Tecsun S-8800 Review

by 13dka

Looking for a new toy again I recently revisited the Tecsun S-8800, which looked like it could replace both my battered old Grundig Satellit and my Tecsun PL-660.  Being in production for a few years now, and with the “birdies” situation ironed out long ago, the S-8800 has gathered much acclaim by now but also a few somewhat contradicting reviews.  For example, one review reports that the S-8800 can cope with larger antennas, another one states the exact opposite, one praises the MW performance, another one attests only average sensitivity, and only one mentioned an unpleasant detail I’m going to emphasize on in a bit.

All reviews touted the improved SW performance in AM and SSB though, and that was reason enough to make my own experiences.  Testing it turned out to be a bit of an emotional rollercoaster though.

I hope I can share more than only redundant bits of information about the radio, and I’ll skip most of the general information you can read in most other reviews.

Off to the 13dka radio test site at the dike!

13dka’s SWL Happy Place

General

Like the technically somewhat similar Tecsun PL-880, the S-8800 is a triple conversion receiver and has 2 conventional IF stages, the third IF stage is using a Si4735 DSP chip again, providing the  filters and all that jazz.

Tecsun seems to have thrown a lot more parts into it than in previous radios, plus a pretty big ferrite rod (covering 8-9/10th of the radio’s width) with individual LW and MW coils (most of the smaller receivers have only one coil), a 108mm telescopic whip and of course the “gun metal” knobs.  Designing a radio with a rather simple front panel and making a remote control an integral part of the operation concept (like it is reality with TVs for a long time) is a charming oddball approach, in a way reviving an utmost luxurious feature of 1930s high-end radios.  So let’s cut to the chase and talk performance:

Longwave and Mediumwave

On LW and MW, I first compared the S-8800 with my old Grundig Satellit 400 at home.  The old clunker has similar dimensions, a big old speaker bass/treble controls and it was known to have an average sensitivity on the AMBC band in its time, when all the great, now vintage AM performers were still ubiquitous, so that’s rather a “Jay Allen average” than an “average of the mediocre AM radios of this millenium”.  I think Jay Allen might rate it 3 stars.

Longwave

The first station I tuned in was the BBC LW transmitter network on 198kHz and it turned out a tad more noisy on the Satellit.  Great!  I could also pick up Medi1 and Kalundborg a smidge better than on the Grundig, and in the early evening, out at the beach I was picking up stations on all still populated channels on LW (minus 180kHz where it has one of the remaining birdies).  The other new portables I currently own (PL-660, D-808) are far away (PL-660) and far, far, far away (D-808) from that kind of performance.

Mediumwave

Unfortunately that good impression vanishes gradually when leaving the long wave for the NDB band (still good) and finally medium wave.  Before I left the house to test the radios on the electrically quiet beach again, I was checking out one of my favorite border case stations (low power station from The Netherlands on 1602kHz, whatever their name is this week) and that made very clear already that the S-8800 can’t hold a candle to the Satellit, at least not on the top end of the MW band.  Despite all the noise indoors, on the Satellit I could easily recognize the song being played while the S-8800 didn’t pick up anything at all.

On the beach it turned out that – despite the ferrite rod being twice the size – I find it only marginally better than the PL-660, and not close enough to the little XHDATA D-808 (if you’ve read my D-808 review you already know that this little radio is almost on par with the Grundig on MW):

Of course I have read Thomas’ assessment of the AM performance so I was prepared to be underwhelmed.  But at least you can connect some high gain MW antenna to make up for the missing sensitivity and be happy again, or can you?

A not so nice surprise

The unpleasant detail I mentioned before is:  the Int/Ext Antenna switch does not turn off the internal ferrite bar antenna.  Jay Allen mentioned it in his review, it was the only review with that detail and unfortunately I overlooked it.  How does that matter?

The main issue is this: if you’re (like me) forced to use outdoor antennas to escape high indoor noise levels, the internal loopstick just won’t let you.  The external antenna will just increase the SNR a bit when the station is strong enough anyway.  Even in a low noise environment, the internal loopstick will needlessly add noise to the signal received from a high-performance active loop or FSL antenna.

That also explains a paragraph in Thomas’ S-8800 review:

“I also hooked up the S-8800 to my large horizontal loop antenna. This certainly did improve MW reception, but not as dramatically as I hoped. Additionally, it seemed to be very sensitive to RFI in my shack even when hooked up to the external antenna.”

There’s more external antenna idiosyncrasy:  only the BNC jack is wired to the “Ext” position of the antenna switch,  the “hot” (red) Hi-Z terminal is active when the switch is in the “Int”-position, it just seems to save you an alligator clip on the whip.

The dedicated “AM antenna” terminal was in part what sold the S-8800 to me.  The label made me assume this would be specifically wired to the AM circuit but as it turns out it’s just a generic high impedance input and I really didn’t anticipate that the internal loopstick remains always active (or in case of the Hi-Z terminals, the retracted whip).  Yes, technically you can connect an external antenna for MW, practically…YMMV.

To conclude this section, the final outcome of this antenna connector issue plus the not so brilliant MW sensitivity was that not even my active ML-200 loop (connected to the BNC-jack) could improve reception on 1602kHz enough to make the S-8800 get at least a bit into the ballpark of the Grundig with its loopstick antenna.  The currently mounted small 80cm rigid loop on the ML-200 just couldn’t produce enough signal to lift the station over the noise that much.

Shortwave SSB

As the other reviews reported already, Tecsun has obviously worked on the AGC issues their former products had.  I can confirm this so far, the AGC does not show the distorted onset of leveling anymore – unless the signal is very strong.  But the leveling happens much faster than e.g. on the PL-880 so the remaining blasts of distortion are quite short:

A more relaxed AGC release time would save us most of those too.  I noticed AGC pumping effects from strong signals in the spectrum neighborhood only with a big antenna connected.  But unfortunately there is more…

Stuff you have to live with:

In his great review, Thomas mentioned the auto mute sometimes interfering with reception. I noticed this too (with all bandwidths on SSB) and I credited this to very low noise figures. When the bandwidth is narrow (=less noise) or if you have a very low noise floor anyway like when tuning through 25-30MHz, the receiver gets muted over the entire chunk of spectrum, just to intermittently and pretty suddenly pass the noise again.  Sounds like a broken antenna cable and has some potential to confuse people:

Then I made some experiments with ECSS, destroying my “noise floor” theory.  It doesn’t always happen but under circumstances that may sound like this:

Too bad that setting auto mute to ’00’ doesn’t actually turn it off in SSB mode so there’s likely no remedy for that.

On my example, there is absolutely no difference between the 3kHz and 4kHz SSB filters.  A working 4kHz filter would have been a good choice for ECSS reception.

Another remaining quirk at least on my specimen of the S-8800 is a slight FM modulation of an oscillator in SSB, particularly with strong signals.  You can hear it best if you create a heterodyne or listen to CW, the tone sounds a bit hoarse, so do voices and I’m not sure whether or not this could affect narrow-bandwidth digimiode decoding.  The front panel (namely the bandwidth knob area) is quite susceptible for “hand capacity”, the frequency varies a bit when you move your hand in front of the S-8800.  This is not uncommon with portables of course, but my D-808 for example has its “Theremin playing area” on the back of the radio.

In this clip you can hear both the “hoarse” modulation and my hand waving  to you.

This leads me to calibration and frequency drift.  The S-8800 can be calibrated on SSB (see the “Hidden features” section below), however this turned out to be a (too) fast moving target.  I don’t know if it’s the VFO or the BFO but it is so temperature-dependent that 6°C temperature difference equates to a quite substantial (for SSB) drift of 150Hz.  Whatever oscillator it is, it seems to lack any temperature compensation measures, with all the implications that may have on relaxed SSB listening, digimode decoding and ECSS reception when the temperature isn’t quite stable where you want to use it.  After calibrating it, it’s often slightly off again within the same minute.  My cheap little D-808 won’t drift even when I take it from an overheated apartment into a -5°C cold winter storm.

The good stuff

Now to the fun part!  When I compared the SSB performance of the S-8800 with my PL-660 the first time, I found them very close for some reason.  I could find only one weak station that came in noticeably better on the S-8800 and while I was happy that it wasn’t worse than the PL-660 I was also a bit disappointed.

Timeline: 0:00: PL-660, 0:10: S-8800 receiving the “Gander Radio” VOLMET.

Then I repeated the test a few days later, this time a bit more into the evening and the outcome was very, very different.  The S-8800 won every single weak signal comparison with ease and sometimes in a way that made me think my PL-660 must be broken.

But then I could help the PL getting a lot closer by simply holding it in my hand, the difference was that I had placed the PL-660 differently so I could record both radios easier.  The factor I forgot to put in the equation was that the S-8800 is absolutely not depending on anyone holding it to give it some counterpoise – that and the long whip is certainly a part of its advantage, and the receivers would be much closer when used with the same external antenna.  With the radios just standing there tho (and that’s what most people will do with their radio instead of holding it in their hand), the difference is remarkable nonetheless and I also learned that you should always look and listen twice when testing radios!

When I repeated the test yet again but granted the PL-660/D-808 the litte bit of counterpoise they seem to need (I let them rest on the car door instead of holding them), the results were not that unequivocal anymore.  However, the receivers were 50% on par, the S-8800 was clearly better the other 50% and overall the other two receivers could not score a single point for them.  I think that shows that the S-8800 really is a hair or three better.  Beyond the increased sensitivity and minus the frequency drift, SSB reception feels more mature, the the S-8800 behaves more like a regular communications receiver now and the big speaker is a big plus.  Of course that means there should be also an improved reception of…

Shortwave Broadcasts

I know that the S-8800 has inherited the “Enjoy broadcasting” and “BCL RECEIVER” lettering from the cheap S350, but after stepping the PL-660 and the S-8800 through all shortwave broadcast bands, I felt that’s exactly hat it was made for, and it shows!

There is no doubt that a big speaker can create the illusion of better reception, but I think I don’t fall for that easily and rather listen to the background noise and how intelligible the “content” is.  While the comparison with the PL-660 often ended up in a tie when I subtracted the impact of the speaker in my mind, there were indeed some stations where the S-8800 had remarkably less noise than the PL-660.  But of course the big speaker is giving the S-8800 a permanent edge on all reception cases, and it’s a real joy to listen!  Combined with lower noise and a generally more stable signal (through better AGC) this made quite a difference between the two.

Bottom line is that when listening to shortwave broadcasts, the S-8800 gives you the warm and lush sound of yesterday’s famous receivers while it technically delivers the best performance of all Tecsun portables so far.  If you fancy music programs on shortwave and if you don’t mind the price for the luxury and performance, you’ll enjoy this radio a lot.

FM

Short story: my specimen of the S-8800 lacks the very good FM band sensitivity of the PL-660 or the XHDATA D-808.  While the latter radios present my favorite marginal case station 100km away  fairly with some noise at sea level, the S-8800 just doesn’t receive that station at all, no matter how I position the whip.  It’s not exactly worlds between them but considering that (assumedly) most of the FM receiver is in the Si4735 chip that it shares with a couple of great FM performers from the same company, this is a bit surprising.

Signal handling capabilities

The S-8800 is said to have a pretty robust frontend, which I found true but I want to put that a bit into relation.  My “lonely beach/dike listening post” sports 2 abandoned steel flag poles of 6 and 8m height.  They can serve as support for wire antennas, or easily be used as an antenna themselves by inductively coupling them to the receiver – IOW by winding a wire 2-4 times around the pole (you could use the Eiffel tower as an antenna this way) and connecting the other end to the radio.

For some reason this contraption produces quite massive output voltages, but I could always use it for a quick and thorough (and due to the location QRM-free!) reception improvement with my PL-660 anyway.  Why?

The PL-660/880 have a 3-position (DX, Normal, Local) switch. I think it turns off the input preamp in the “Normal” postion and adds a simple attenuator circuit in the “Local” setting.  The latter is sufficient to tame the output of all sorts of antennas (including the flag pole) enough to make my PL-660 work just fine with that on all bands.

The S-8800’s sensitivity switch on the other hand has only 2 positions and telling from the results it really only turns off the preamp.  Now it actually acts up much less on the flag pole than the PL-660 in its comparable “DX” and “Normal” positions, so obviously Tecsun has put some effort into making the frontend more robust indeed.  But it seems they thought “that should do, let’s ditch the 3rd (attenuator) position and save 3 resistors” and that left me with many (but tolerable) images across the entire shortwave above 3 MHz, and a heavily image-infested 160m band.  BTW, a few soft images from (I guess) 49/41m blowtorches could be heard around 29MHz with only the whip.

A word on the audio

I believe that the “legendary” status of the Grundig and Zenith lines of world band receivers is partly owed to their big sound.  They had their music loving and program listening audience in mind, and Tecsun’s choice of casing, big speaker, the bass and treble controls are certainly taking the same line.

Compared to my Satellit 400 (80s model, but still has much of that “legendary” sound), the Tecsun sounds a bit more boomy in the lower mids while having a less super-deep bass response than the Grundig, which also sounds more neutral.  Besides these very unimportant distinctions, the S-8800 does sound big and that also helps reception – lacking low mid/bass content can impair intelligibility as well, and it causes more fatique on long DXing sessions.

The bass/treble shelving EQ is certainly more sophisticated than the Grundig’s, it has quite sharp cutoffs at very sensibly chosen frequencies, so turning the knobs down will leave the main chunk of the mid range completely unaffected and just helps removing rumble or the 5kHz beat frequency from a band neighbor, or add some nice hifi-highs and beefy low end when you turn them all the way up.  In other words you can continuously blend the speaker sound from perfect “voice communications” style to “dad’s big old radio”.

Hidden functions

Of course the S-8800 has some unofficial “power off” and “power on” extra functions assigned to the number keypad on the remote (they all work by pressing and holding a number key for up to 10 seconds).  Some are identical to the PL-880, some are different:

0.) I found calibrating the S-8800 on SSB works with the same method used on the PL-880:  Tune to a station with a known frequency, switch to USB or LSB and use the fine tuning knob to tune for best audio/music playback. An alternative way of doing this is downloading a free spectrum analyzer app for your smartphone (“SpecScope”), tuning the radio 1kHz off frequency so you get a nice heterodyne tone on USB or LSB, then using the fine tuning knob to tune the tone to hit exactly the 1kHz mark on the analyzer display.  Your last 2 (Hz) frequency digits will now show an offset frequency.

1.) Then press and hold the ‘0’ button until a ’00’ appears in the top right corner of the display and the last 2 digits of the frequency readout start flashing.  Release the button and quickly use the fine tuning knob to reset the last frequency digits to ’00’ (the number on the top right corner should be changing while doing that), then immediately hold the ‘0’ key again to confirm – tadaa, the offset should be gone while the last 2 frequency digits show ’00’ now.  This all needs to happen pretty quickly and with the right timing, so it may take a few attempts to get it right.

2.) With the radio off, button ‘2’ turns the LW band on/off.

3.) Press and hold the ‘3’ button while the radio is off to toggle between permanent and “intelligent” display illumination.

4.) When the radio is turned on, this button enables access to the extra functions of the number 6 and number 9 keys.  The display will read “On” when you perform this the first time, doing it again will turn it off again.

5.) Radio on, set to FM band: this toggles between 75 (US) and 50 (anywhere else) microseconds deemphasis on FM.

6.) Radio on: When enabled using the ‘4’-button as described before, holding the ‘6’ will toggle the (annoying) dynamic bandwidth feature off and on.  You can set this independently for AM and SSB.  Ideally to zero, because it automatically resets your bandwidth setting and since this is happening in steps, it sounds quite strange.  The PL-660 uses a stepless dynamic envelope following low pass filter (which is I believe what they called “DNR).

7.) This is still a mystery to me.  On the PL-880, this button apparently controls the line out level on FM.  On the S-8800 it (ostensibly) seems to control the S-meter bias with numbers running from ’00’ to ‘+99’ and ‘-99′ for all bands.  Positive values reduces the S-meter display which made me curious if it rather controls AGC level or gain at some stage, but it really seems to affect the S-meter display only.

8.) Radio off: Toggles the seconds display on the main clock (when the clock is displayed instead of frequency).

9.) Another important one: this controls the threshold of auto squelch/soft mute.  If you want to turn that off, turn it down to ’00’ with the main tuning knob, then hit the ‘9’ key again.  You need to do this for AM, FM and SSB separately.

Random stuff

  • The S-meter was indicating a permanent base level of 2 bars even at my remote beach listening post.  But even though it can apparently be “calibrated”, a 5-bar indicator is quite a step backwards from the 99-step RSSI meter of the PL-880.
  • After an initial discharge and recharge cycle, the 2x2000mAh “18650” batteries gave me a continuous runtime of 21 hours.  When you connect the charger and then turn on the radio, it stops charging unless – and this seems odd – you are in FM mode.  A full charge while listening to FM radio took 4:41.

Verdict

I had a pretty hard time making my mind up about this radio.  It has so elaborate details, so much design improvement and costly parts went into it but I feel like it doesn’t quite meet the expectations Tecsun created with this radio.   Sadly, it has a few things that were started ambitious and ended underwhelming.

It got a huge 2-coil loopstick and somehow they managed to make it perform slightly worse than a 70€-radio with not even half of that loopstick size, they gave it 2 external antenna ports but they disappoint MW enthusiasts right again by keeping the loopstick always active, and how FM could turn out less sensitive than many radios with the same Silicon Labs chip (including their own models) is beyond me.

They improved the front end but then they dropped the attenuator, which costs the overall flexibility and better overloading-resilience their other radios have, they fixed the SSB issues of the predecessors and introduced a free-floating BFO with a mind of its own.

The price tag is making these downers certainly weigh heavier, and I think without them this radio may have turned out to be a real classic.

On the plus side I found a radio that really excels on shortwave. Shortwave program listeners can feast on a most sensitive, selective, luxurious and well-behaved portable with a big sound and I think there’s probably no current portable that could compete with that.

Ham radio aficionados get improved SSB reception and if there wouldn’t be this “cheap 70s receiver trademark” unstable oscillator, it would come close to communications receiver performance levels (minus the frontend needed for big antenna voltages).

That the price reaches into the ballpark of pre-loved high-end(-ish) JRC/Icom/Yaesu communication receivers or buys you a mint-condition ICF-2010/2001D may seem like a problem too.  But then again, none of those radios is perfect either, and only the Sony is a portable.

Despite the quirks, the S-8800 is still a great, valuable radio that revives an out-of-fashion style of radios in a pretty unique and modern way.

What a brilliant, critical review of the Tecsun S-8800!  Thank you so much for taking the time to properly test and compare the S-8800 with the venerable PL-660 and the XHDATA D-808 (readers, also check out his review of the D-808).

You’re right, too, in that I’ve noticed some contradictions in reviews–I do wonder if part of this might be variations between US and EU versions of the radio, or perhaps small quirks in production runs.

No doubt, however, that the Tecsun S-8800 is a champion of the shortwave broadcast bands and its audio fidelity is in a class of its own.

A review of the Tecsun R-9012

by Laurence Neils

I have cheap radios. I can’t really justify buying more expensive ones given how much time (not all that much) I spend listening to the short wave broadcasters. The consequence of this is that, when I do listen to shortwave stations, I have the rather standard ultraportables to listen on.

My go-to radio is the Tivdio V-115, which has pulled out quite nice reception for me, and offers several functions I like a lot. However, it was missing one that interested me the most: analog or analog-like tuning. If I want to listen to something, I either have to know its frequency and try it, or I have to let the radio do an automatic scan. While it’s quite good at pulling out stations and letting me hear them, it can take a few minutes to do a full scan, and canceling it doesn’t result in the part scanned so far to be stored. Very few stations I am interested in hearing are convenient to jump into several minutes after they start (my interest is in spoken content rather than music, and neither news nor stories make a ton of sense if the introductory information was not heard).

From a recommendation here on the SWLing Post, I chose to purchase a Tecsun R-9012 radio to help me do a convenient scan, which is useful because it allows me to find stations without knowing their frequency, and leaves me to not remember all seventy frequencies a certain broadcaster is using this year.

Physical Description

When I bought my Tecsun R9012, it arrived quite quickly from Amazon. It included a short manual, whose contents could be loosely paraphrased as “insert batteries and turn on”. Other than that, the radio is all that’s there.

The R9012 is relatively small, but not as thin or compact as the Tivdio, which will be my main comparison unit for this review. It is your basic rectangle form factor, and about the size of the small tape recorders that were the last to be phased out for portable recorders. It would be easy enough to put this in a backpack, jacket pocket, or glove compartment, but you have no chance comfortably fitting it into a standard pocket. On the back, there is a flip-out kickstand that can hold the radio at about thirty degrees from horizontal and the battery compartment. This radio is powered from two AA batteries.

The right side of the R9012 contains the analog tuning knob, which I will discuss quite a bit later, and the power switch, which is not connected to anything else (not integrated into the volume knob or mode selector).

The left side gives you a 3.5mm audio out jack. This supports all the headphone types I’ve tried. One benefit of this radio is that headphones with integrated microphones, such as the ones that come with the iPhone as well as various sets that are intended for phone use, will work with it. Some other radios won’t work well with that type of headset. The Tivdio, for example, will play through the headphones but forgets to turn off the speaker if there is a microphone on them, making the headphones pretty much pointless.

Next to that jack is a power port, supposedly to recharge the batteries. A connector for this is not included, nor do they seem to sell one. I suppose the theory is that you might already have a suitable one in that box of old cables we all have, but I can’t see this as a particularly useful feature given the RFI you’ll get if you connect a radio directly to the mains to recharge. Above the ports is the volume knob, which is a very basic analog one, and then the wrist strap, which is integrated into the case. There doesn’t seem to be a way to remove or change it, should you desire that.

On the front of the radio, the speaker takes up the left half. This is fine for standard listening, but don’t expect wonders of audio fidelity. On the right half, there is the twelve-position mode switch (from left to right, FM, MW, SW from low to high frequency) and the tuning display.

FM performance

The Tecsun has a standard FM function, with stated coverage from 76 to 108 MHz. This is the leftmost position on the mode selector. The band is not divided into multiple switch positions, meaning that stations will be relatively packed into dialing space when compared to shortwave, which is spread across ten bands.

I didn’t buy this radio to use it for FM. I have very little interest tuning for FM stations. Some people may enjoy the experience of manual tuning for a station they can locate quickly, but I’m not one. I can easily type the frequency I want on my Tivdio, and I intend to keep doing that for FM. I mostly intended to test FM performance on the R9012 because I was curious to see whether there would be anything audible in the 76-87 MHz section. I know that our TV standards have switched off using analog audio, so I assumed there would be nothing, but I’d never formally put that to the test.

FM on the R9012 has problems. In fact, it has a lot of problems. Among other things, the FM process on this radio doesn’t seem to have a very good idea where things are. I’d be tuning through looking for some station and I’d find it…only to see that I was in a completely foreign part of the spectrum where that station had no business being. It seems that, unless you’re very focused in on a station, the R9012 is liable to pick up some other broadcast and layer them on top of each other. Never mind that the broadcasts have nothing to do with each other and aren’t anywhere near each other on the band. If you have a specific station you want, you can tune to it and have no problems. If you want to see what’s there, you’ll have a very fun time listening to stations that you might want to listen to, only to find that that was an image, you’ve lost it now, and you can’t find it again.

Sometimes, I managed to find a part of the spectrum that gave me three different images simultaneously. Ironically, the broadcast I intended to use as my landmark, the local classical music broadcast, which is located very close to the middle of the FM spectrum, was strong enough or at a coincidental frequency that I identified images of it at six different places on the scan, in addition to where it should be. So I got my answer about 76-87 MHZ. According to the R9012, there’s a lot of signal there. It’s just coincidence that it sounds exactly the same as standard FM broadcasts with extra static.

FM performance gets worse: this radio is extremely sensitive to location.

In order to get nice reception, you have to have the radio in a good position. This seems to be completely random. Standing up so the antenna lies flat on the top, but is not extended produces almost silence. Lying down so the antenna is touching the table (not a metal table) or chair (not a metal chair) causes most signals and images to come through quite clearly. Extending the antenna to medium length helps reception. Extending it all the way introduces a lot of interference. On FM, volume also changes a lot. We may reasonably expect for the signal to change if we connect something conductive to the antenna by, say, touching it with our conductive fingers. Maybe reception will get more static, or maybe it will in fact improve. What we don’t expect is for the broadcast to switch from comfortable volume to let’s see if we can get you some tinnitus volume. Unfortunately, that’s sometimes what happens on FM if you touch the R9012’s antenna. Or tilt it a bit in the wrong direction. This doesn’t seem to happen much if it is tuned onto a station, but if it is anywhere in the middle or if there’s some static, the volume change is very noticeable, in that it makes you want to get the radio off as soon as possible.

In summary, this radio just can’t really do FM. If your other radios are broken, you’ll be fine by using this, but don’t buy it if you intend to do FM things.

Mediumwave performance

The MW frequencies are mostly there, with stated specs including from 525 to 1610 kHz. While there are broadcasts between 1610 and 1710 KHZ, that’s not a ton of the spectrum. I don’t have much interest in MW. I tested the radio’s performance, and it seems fine. Strong stations come in loud and clear. Stations that have low broadcast powers are easy to tune in. I was able to get some skywave MW in here as well, but I really don’t have any interest in that. I was able to verify, however, that the terrible effects that plague FM performance don’t appear on MW. I got no images of distant stations, no rapid volume switches, and the position of the radio doesn’t seem to affect MW reception all that much. Perhaps this is due to the different antenna that most radios employ in tuning MW. However, the manual doesn’t say whether this radio has such an alternative antenna and I haven’t gone to the effort of disassembling it to find out.

Shortwave performance

Once again, the crazy stuff seen on the FM band doesn’t appear during shortwave listening. I was able to tune in quite a few stations, although this probably isn’t a DX-capable device unless you’re willing to go out into RFI-free areas. That sounds enjoyable, but it’s not really my thing. When I got signal, it came in quite clearly. I got very little interference from the device itself, although it does seem quite susceptible to RFI from power lines. Of course, so is everything else, but if you put its antenna closer to a line, you’d know it.

Frequency coverage

Shortwave is covered in ten bands that allow access to the more populated areas of the spectrum, but have many gaps. Certain descriptions claim that the radio has coverage from 3.90 to 21.85 MHz. This is so misleading I’d be willing to call it a lie. The actual ranges are as follows:

  • SW1: 3.7 – 4.10Mhz
  • SW2: 4.75 – 5.06Mhz
  • SW3: 5.95 – 6.20Mhz
  • SW4: 7.10 – 7.30Mhz
  • SW5: 9.50 – 9.90Mhz
  • SW6: 11.65 – 12.05Mhz
  • SW7: 13.60 – 13.80Mhz
  • SW8: 15.10 – 15.60Mhz
  • SW9: 17.55 – 17.90Mhz
  • SW10: 21.45 – 21.85Mhz

So what if most signals are in there somewhere? Those gaps are very large. For example, the only broadcast frequency for WWV that would be covered on this set is the 5MHZ one. 10, 15, and 20MHZ are all located in various gaps on the bands.

This turned out to be quite annoying. I know that these are standard areas of the spectrum, in which people place a preponderance of broadcasts, but the fact remains that a lot of broadcasts occur between the bands on this set. I checked the A18 shortwave schedule to identify how crazy I was. Of the 5530 broadcasts that were listed between the limits of 3.90 to 21.85 MHZ, 1870 of them or 33.8% of the total, are outside the range of this set.

It strikes me that the largest band on this radio covers only 500 kHz of space, whereas the smallest gap between bands covers 750 kHz. In many cases, bands cover only 100 kHz of bandwidth. While I guess it’s better that they’re there rather than their being completely absent, perhaps some effort could have been done to open that up a bit more. I quickly analyzed where missing signals were, and if Tecsun could extend the 5.95-6.20 MHz band down to 5.8 MHz, 7.10-7.30 up to 7.60 MHz, expand the 9.5-9.9 band, and give an extra 50 kHz to the 11.65-12.05 band, most of the missing spectrum, nearly a thousand broadcasts, would be brought back into coverage. This could be done and still keep the maximum band width at 500 kHz. Therefore, as they didn’t seem to feel this an important issue, it falls to me to consider it so.

Manual tuning

So I bought this to tune manually. It stands to reason that I should review how well it does that.

The analog dial is on the right, and protrudes outward. Once again, the knob does its job, but not all that well. It was very easy to use this to pan through the spectrum and pick up stations, but the wheel doesn’t make it all that easy to do so quickly. You have to turn it by grasping, as the wheel has a fair bit of resistance. I don’t doubt that this feature helps to keep from knocking it off frequency, but you have to use two fingers to rotate freely, and that slows the process down. Meanwhile, the wheel has a rather disconcerting way of stopping, where the wheel seems to have hit an obstruction. However, this essentially increases the resistance, rather than feeling like a barrier. It’s noticeable, but it feels like something’s blocking the turning mechanism, rather than that the mechanism has reached its limit. Actually, it is possible to keep turning the dial, which I assume will eventually damage something, but if you’re not used to how it feels, you may do so without realizing that you’re not actually going anywhere.

The wheel has quite a bit of travel. On my set, it will rotate about three full turns. I believe this is necessary because all of FM, including the standard and Japanese bands, is in one section. Therefore, the wheel needs to be able to turn a lot in order to separate those stations. However, this means that panning over a shortwave band that covers at most 500 kHz of spectrum includes a great deal of panning over static. This works to scan quickly, but there are undoubtedly even faster ways to do so.

Conclusions

It’s a radio. It will pick up stations and make noise. In that, it works. However, this isn’t exactly a great set. The $22 price tag may forgive some of its flaws but not all of them.

Radios like the Tivdio models cost similar amounts and cover the spectrum more fully with some extra features. When I purchased this model, I expected the lack of features to be made up by convenient scanning over shortwave, relatively good sound, and relative disposability. I got enough for me to keep the set, but nothing more.

Pros:

  • Mediumwave is rather sensitive for those who enjoy listening to those signals.
  • Radio has a kickstand and the antenna can be rotated freely.
  • Radio supports headphones with inline microphone.

Cons:

  • FM is plagued by images of other stations that should not be there. This is rather bad.
  • FM is far too sensitive to antenna position.
  • Shortwave coverage, while it includes most of the spectrum in use, has big gaps that are actually being used by a lot of broadcasters.
  • Analog tuning works, but not really well. The knob can turn but does so with effort.

Would I recommend people to purchase this? Probably not.

Those who have higher-priced devices will get nothing from this. Those getting into the hobby aren’t going to get a ton of benefit from this, because tuning on shortwave requires enough familiarity with dial position that they may spend too long figuring it out. It would be useful on FM only if most other radios have been broken. It’s not even that good as an emergency set because of the FM sensitivity problem.

If all you want is analog tuning over the bands that are provided, the radio will do it for you. If you want more, buy something else.

Thanks for sharing your evaluation Laurence. Thanks for focusing on one of the points that is often overlooked with analog radios: the frequency coverage on various shortwave bands. The R-9012 does seem particularly segmented.

The Professor reviews the XHDATA D-328

8 Replies

Many thanks to SWLing Post contributor, The Professor, who shares the following review of the XHDTA D-328:

First off, this is the best radio I’ve ever operated… that cost me less than ten dollars new. When I saw the promotion on the SWLing Post for free or half price radios, I had to bite, especially because the deal was that the first ten to respond would get a free XHDATA D-328. They told me I was the 15th caller, so I was allowed one for half price. And since they were going for just under fourteen bucks on Amazon, it felt like it was almost free.

Of course, I didn’t expect much. But as they wanted the people who received these free or very inexpensive little radios to leave reviews, I figured the Chinese manufacturers knew there were some good features radio folk might notice. And there are. And I’m not sure if I’ll post part of this brief review on Amazon, but I’ll do so here in this comment.

If you want a radio that will reliably pick up local AM and FM stations and play some MP3 files, this will work, and work pretty well. And it doesn’t sound bad at all for the size. I personally don’t have much love for these new analog-style tuning DSP radios, but I suppose people who aren’t as radio wise as readers of the SWL Listening Post won’t notice the less than poetic effects of moving between stations on these sets. Most probably tune in their desired stations and just listen to it, and this radio does this well enough.

I don’t really listen to FM much, but the XHDATA D-328 seems adequate enough. And with headphones on it sounds quite rich on FM. AM isn’t bad either, but it’s far from selective. I was able to dig out clear channel regional biggies like Zoomer Radio at 740kHz and WHAS at 840kHz in Louisville from here in Brooklyn at night, but in between often easy to find fifty-thousand watt stations like WBBM or CKLW weren’t there. The DSP tuning just defaulted to the next local station like WNYC or WABC when I turned the dial.

Shortwave was worse. Beyond the U.S. powerhouses like WWCR this radio doesn’t seem a very worthy shortwave set for those of us in North America. But I can imagine in that in third world countries where international and local broadcasters still target broadcasts that this radio might be an inexpensive way to access that programming.

I must admit that listening to MP3 music files was kind of pleasing. Again, the audio is really good for a radio at this price point. However you are listening blind, there’s no screen to tell you what you’re hearing, and no shuffle function to make a folder full of MP3s into unique sequences of songs each time. What you get are the songs in the alphabetical order of the file titles, although you do have the option to jump ahead 10 files before or after the one you are playing. So the best use of an MP3 player like this would be to listen to podcasts or whole radio programs with it. What I would do is copy the files onto the SD card and then perhaps number the filenames in the order I would like to hear the shows.

So, for the price there’s not a lot to complain about. People have already mentioned the off-center small kickstand, and that’s a little cheesy. But the tuning thumb wheel moves smoothly thru the imperfect DSP tuning function, and the volume thumb wheel is actually analog which make it much easier to get the exact volume you want out of this radio. But the sliding band selection switch under the tuning scale is a bit worrisome, as I’ve had a few cheap Chinese radios with a switch like this and just normal use eventually rendered them unable to switch bands adequately. This one feels a little bit more stable then they did, but time will tell.

All that said, there are radios that are not too much more expensive than this radio that offer much more in a number of ways. The small and inexpensive analog Tecsun radios from a few years ago are a case in point. Selling for twenty to thirty dollars, those multi-band radios are a little challenging to tune (a stiff thumb wheel on some), and the tuning scale may be a little off and they may drift a little, but the analog tuning is a much better experience. And you can DX with them. I remember listing to All India Radio with a decent signal one afternoon on my Tecsun R-9710.

There’s a lot of similar analog radios which I believe are probably just about the same radio – the Tecsun R-9012, the Tecsun R-911, the Tecsun R-909 and the Kaito WRX-911, among others. Once you get a look at these you’ll recognize other similar radios in this family. I’d say they’re the best really cheap receivers I know of. They generally run between twenty to just over thirty bucks. I believe these radios appeared on the scene in the early 2000s.

I have this fear that they’ll start turning these radios into DSP sets. That would be a real shame, but I’ve heard no mention of that. However I did notice that the marketers of the XHDATA D-328 didn’t even mention that it was based on a DSP chip. And Chinese manufacturers are notoriously not very open about how they are altering radios that they’re putting out, so be aware of that.

As far as MP3 playback, the one radio I would really recommend is the Meloson (or Tesslor) M8 (or the Meloson M7 or S8 if you can find one). It’s simply the best audio you’ll hear in a really small radio, AND you can shuffle the MP3 files in a folder with these. While it only give you the sequential number of the song in the display, it will generate a unique sequence of songs each time you shuffle. Fill a folder on a card full of songs and let it rip. It’s the perfect micro music player if you make a good folder of music. And the DSP radio in these is not bad either. It’s digital, not fake analog tuning, and most AM clear channel targets you can usually find at night in your region will show up on these. They used to go for less than thirty bucks, but right now I see they cost close to fifty dollars.

Two other radios I have that I can recommend for MP3 playback, are the Tecsun ICR-110 and the Tivdio V-115. Neither one offers playback shuffle, but they will play the files in alphanumeric order just fine. But they both have a cool feature in that you can press a button and record the broadcast you’re hearing as an MP3 file. And they both also sound great. The Tivdio has incredible sound for a tiny radio, but the ICR-110 is even more impressive. I believe it has the same speaker setup as the much more expensive Tecsun PL-880 and it also has similar warm and clear audio.

The reception with the V-115 is OK, nothing stellar, but the ICR-110 is kind of a monster on medium wave. I’ve been impressed. The ICR-110 is rather big compared to the other radios I’ve mentioned, closer to the PL-880 in size, but quite a bit lighter. The ICR-110 used to be cheaper, but can be found for around forty bucks. The Tivdio V-115 still goes for just under twenty if you look around. A bargain. Tecsun, Tivdio, Degen and other Chinese manufacturers have all sorts of inexpensive radios for sale out there, and others I haven’t used or mentioned might be quite good as well. If one appeals to you, do a little online research.

Of course, since I’m talking about small and inexpensive radios I should mention that the Tecsun digital DSP sets like the PL-310ET, the PL-360, PL-380, PL-390 and other variations are all amazing inexpensive radios that will run you around 35 to 50 bucks. The ultralight DX community loves these things, and for good reason. And there’s a version of the PL-390 that plays MP3 files from an SD card and another that offers bluetooth playback. No, none are perfect, but they’re solid sets, and all would have been dream radios thirty years ago.

So, that’s my evaluation of the XHDATA D-328, well worth fourteen dollars, but for a few dollars more you can get radios with similar features that do much more. It’s small, it doesn’t sound bad, and it’s fairly well-built. It will pick up all your favorite local stations and play all your MP3 podcasts effortlessly. Not bad. Like I said, it’s the best super cheap radio I’ve ever used.

Excellent review!  I’m impressed that the D-328 has enough AM performance to grab some  night time clear channel stations. It’s disappointing, however, that it lacks performance on the shortwave bands.

Thanks for posting your review–always great to hear from The Professor!

A review of the Tivdio HR-11S self-powered shortwave radio

8 Replies

A few months ago, the radio manufacturer Tivdio contacted me to see if I would be interested in evaluating their new Tivdio HR-11S self-powered emergency radio. I receive requests like this frequently, and often pass on the opportunity since I generally don’t have the time to evaluate the overwhelming number of inexpensive DSP radios that have hit the market in the past few years.

But this time, I seriously considered it.  There were two reasons I was interested in the HR-11S:

  1. I purchased a Tivdio V-117 last year, and have been pretty pleased with it; indeed, I’m overdue a review on this unit. We’ve also posted several positive reviews of the Tivdio V-115.
  2. At our non-profit ETOW, we’re always looking for reliable self-powered radios with shortwave for use in areas of the world where radio remains the primary news source.

Thus this radio is a rather rare breed.  Tivdio dispatched the radio very quickly, but my work with the Radio Spectrum Archive and several other reviews already in the pipeline took priority.

I’ve had the HR-11S in service for several months, and have now explored every feature to some degree. What follows is my summary and review notes.

Green and Red radios are different models

First things first: note that I’m reviewing the Green HR-11S. Tivdio also makes a Red version which is actually a different model number: the HR-11W.

The main difference between these models, as I understand it, is the green HR-11S is a shortwave version, and the red HR-11W is a NOAA weather radio version.

Both are useful; why not combine the two roles in one unit?  I’m not surprised this radio can’t include both shortwave and NOAA weather radio. Through Ears To Our World, I’ve worked with self-powered DSP radios for many years, and know that a limitation of the DSP chip is that it can be set to feature either shortwave or weather radio, but not both, simultaneously, if both AM and FM are included.

Form factor

The HR-11S has a built-in solar panel.

The HR-11S adopts the standard “flashlight” form factor found in so many other self-powered radios. I think the flashlight functionality is a useful feature and results in a handy form factor.  It’s compact, lightweight, and seems relatively sturdy, so is suitable for camping, travel, and off-grid utility.

Flashlight/Siren switch

A small switch on top toggles between four positions. The first two positions are off/on for the main white LED. Though the flashlight aperture is relatively small, the white LED provides enough luminosity to light your immediate path at night, and certainly more than enough to read by.

The third switch position engages a flashing red LED. The red LED is not terribly bright and I’m not sure how helpful this would be in an emergency situation.

The red LED is rather dim and can only flash.

I would much rather have the red LED maintain a steady beam which would be great for amateur astronomers, campers, or anyone else wishing to preserve their night vision.

The fourth position engages a LOUD siren. More than once when attempting to turn on the flashlight in the dark, I’ve accidentally engaged this pain-inducing feature. The switch is small, thus it’s very easy to engage the siren. In a quiet campground, this might annoy your neighbors––not to mention you, yourself.  Of course, in an emergency situation, a loud siren could come in handy. I just wish its switch wasn’t combined with the flashlight switch.

The display HR-11S display is backlit and easy to read.

The HR-11S sports a keypad that allows direct frequency input––a very good thing, considering there is no tuning knob.

To band scan, you must use the #7 and #8 key on the keypad to increase and decrease frequency in predetermined steps. And, yes, the radio mutes between frequency changes.

You can also press and hold the #7 or #8 buttons to engage an auto-tune feature that finds the next strong signal.

The HR-11S’ rechargeable battery pack.

To input a frequency directly, simply press the enter button, key in the frequency, then press the enter button once more to engage that frequency. Very simple.

The volume up/down buttons are #1 and #2 on the keypad.

The keypad is not backlit and the layout for volume control, tuning, mode switching, etc., is a bit confusing; it doesn’t match any other radio I’ve ever used.  Of course, with time you’ll master the keypad functions, but the design could be made more user-friendly.

Performance: setting expectations

SWLing Post community members know that I tend to review what I call “enthusiast grade” radios: receivers that perform well enough to attract the attention of DXers and dedicated listeners.

Self-powered radios, with few exceptions, rarely impress me in terms of performance. Indeed, some of the best that have been on the market have been analog units (I’m particularly fond of the Grundig FR200).

The Tivdio HR-11S is no exception––don’t expect to snag elusive DX with this unit. It’s not going to happen.

FM

The HR-11S is a capable FM receiver. Performance is on par with most average FM radios: you’ll easily receive all of your local broadcasters, but distant stations may require holding the unit in your hand, careful positioning, or adding an extra bit of wire to the antenna.

The FM audio is quite good via the HR-11S’s built-in speaker.

AM

The mediumwave, or AM broadcast band, is the HR-11S’ weakest suit. AM is plagued with internally-generated noises–especially in the lower part of the band–thus you’ll only be able to clearly receive local AM broadcasters that rise well above the noise floor. Thus I cannot recommend this radio for AM reception.

Shortwave

Shortwave reception is on par with other DSP self-powered radios I’ve tested. As I write this section of the review, I’m listening to China Radio International on 9,570 kHz in my office without even having the telescopic whip antenna extended. (CRI is a blowtorch station, however).

I find that the HR-11S can receive most strong broadcasters and even weaker stations, though the AGC is not ideal when fading is present.

If you’re seeking a self-powered radio with shortwave, the HR-11S is somewhat useful in this regard and is worth consideration.

Keep in mind, though, that an inexpensive dedicated ultralight shortwave radio like the Tecsun PL-310ET will perform circles around this unit.

Bluetooth

One feature I’ve found incredibly useful is the Bluetooth functionality.  With Bluetooth mode engaged, you can connect the HR-11S to pretty much any mobile device and use it as a wireless portable external speaker. Since the speaker has decent audio fidelity for the size, and can be powered by battery, it’s a brilliant feature and will make watching videos on your smartphone, for example, that much better.

One negative? At least in my unit, I can hear some internally-generated noises in Bluetooth mode. This is especially noticeable at lower volume levels.

Recording

In full disclosure, I haven’t tested the recording functionality extensively. Built-in radio recording is an interesting feature, but one I would rarely use in a self-powered radio. I did make a handful of test recordings, however, and like many other DSP radios with a recording function, the HR-11S injects noise in the recordings.

Summary

Every radio has its pros and cons. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions and observations. Here’s the Tivdio HR-11S pro/con list, from the first moments I turned it on to the present:

Pros:

  • Keypad entry
  • Great audio for size
  • Replaceable battery (Note: after unboxing unit, you must place battery in battery compartment; it’s packed in the side box)
  • Siren  (see con)
  • Micro SD card for digital storage
  • USB can port audio from PC
  • Bluetooth––use as a portable wireless speaker for mobile devices (see con)
  • ATS (auto tune) function
  • Multiple power sources:
    • 850mAh rechargeable lithium battery
    • hand-crank dynamo generator
    • Mini solar panel
    • DC 5V input (standard micro USB)
  • Backlit informative display
  • Customer service: Tivdio representatives seem to respond quickly to customer emails and comments on Amazon.com.

Cons:

  • Tuning is cumbersome (no tuning knob)
  • Mutes between frequencies
  • Siren too easy to activate, resulting in accidental activation
  • AM broadcast band (MW) is plagued with internally-generated noises
  • Keypad configuration is not intuitive and difficult to memorize for use at night or low light settings
  • Hand strap is very difficult to insert (hint: use a thin loop of wire to help thread it)
  • At low volume, noises can be heard in Bluetooth mode
  • Noises heard in recording function

Conclusion

Running an ATS scan on shortwave.

As I mentioned early in this review, I must set realistic expectations when reviewing self-powered radios. When most consumers consider a self-powered radio, they’re seeking a simple, basic radio that will provide information during times of need: power outages, natural disasters, or while hiking, camping, boating, or simply in an off-grid setting.

Internally-generated noises––especially on the AM band––will disappoint radio enthusiasts. If Tivdio could address this in future iterations of the HR-11S, it would substantially improve this unit.

My overall impression is that the HR-11S is chock-full of features, but none of them are terribly refined. There are even some internally-generated noises in Bluetooth mode, which really surprised me as it seems like an oversight by engineering.

I see the Tivdio HR-11S is a bit of a “Swiss Army Knife” of a self-powered radio. It has more functionality and connectivity than any other self-powered radio I’ve tested to date. Its features will, no doubt, appeal to the average consumer––and a quick look at Amazon reviews seem to support this theory. As a radio enthusiast, however, I would pass on the HR-11S until the internally-generated noises have been addressed.

Jack reviews the Digitech AR-1780

Many thanks to SWLing Post contributor, Jack Kratoville, who shares the following guest post:

A review of the Digitech AR-1780

by Jack Kratoville

As a previous post noted, the quest for the perfect radio drives us far and wide; in this case, as far as Australia. Since it’s rare these days to be able to walk into brick and mortar to touch, play and even bring home a radio to test; I’m grateful for online communities like the SWLing Post to research new and existing product. The caveat being “another must-have for my collection.”

I truly thought I had found happiness with my traveling Grundig tandem of the G5 and G6 – that is until the DSP chip was introduced. For the past 2 years, I’ve been satisfied packing the CCrane Skywave, Tecsun PL-360 and one wild card for domestic travel. My bottom line is when I’m listening to a certain radio in a given location, did I ever regret not bringing something else? The Skywave has satisfied over 95% of the time.

When the AR1780 popped up on this site, something about it piqued my interest. I had heard the Digitech name and it was always associated with a less than favorable opinion. This radio, however, was drawing unexpected praise. It was the video reviews that put me over the top with rich audio coming through even cheap condenser mics. I called Jaycar and had one shipped. Now you can add me to the list of those who are quite pleased with this addition to my radio family.

I’ll start with the primary reason to consider this radio – the sound emanating from the on board speaker. The AR1780 sounds better or as good as any unit this size. And this isn’t just a benefit for FM listening, but for AM/SW/AIR as well. I’ve never seen such tonal balance across all bands.

If you’re looking for a smaller portable with above par performance and excellent audio, you can stop here and place your order. Otherwise, on to my observations:

FM

I enjoy FM DXing and the fidelity of this band. Even though I’ve become accustomed to the sound of the Skywave (it does mellow with age), the AR1780 blows me away. Crisp highs and lows with rich bass that highlights both music and vocals. There is no tonal adjustment on this radio and, frankly to my ears, it doesn’t need one.

Performance is on par with the Skywave and other DSP units. While the Skywave has slightly better selectivity, the 1780 pulls in a tad more signal with its longer whip. The RDS feature works great and is a plus when skips and trop bring in distant signals.

Mediumwave / AM

As sensitive as the Skywave and G5. I’ve gone up and down the dial and my unit doesn’t produce birdies or hets anywhere. Very happy about that. For local signals, once again the sound is wonderful with choices of wide bandwidth. And even with distant music stations, rare as they may be, the AR1780 produces more fidelity than noise. When Zoomer 740 comes in full strength, this radio sounds as good as it gets. Where the Skywave has a tonal advantage is when filtering is at its narrowest. I can still hear signals clearly, whereas the Digitech can get a bit muddy. Depends on signal.

I’ll mention here that the advantage of CCrane’s products is upgraded filtering. The AR1780 burps and clicks when you enter anything on the keypad – even from the Skywave’s keypad if the radios are close to each other! Otherwise, they are very similar in response to outside RF and other noise producing electronics.

Shortwave

I receive everything on this radio as I do on the Skywave & G5.

Where I find weakness with the AR1780 is the soft muting and the scan feature is far, far slower than the Skywave. I’ve scanned for signals on other radios and loaded the presets on the Digitech.

I haven’t found any birdies yet, but it will whistle while starting up on Radio Miami, then calm down completely once fully captured. But that’s only when 9395 is the start up frequency. If I switch to SW and it starts elsewhere and I hit the preset for 9395 – nothing! Strange, but an acceptable artifact. I have to admit, it sounds great listening to music on WRMI!

SSB

I don’t have the Skywave SSB, but the Digitech is slightly less sensitive than the G5. Not sure if it’s due to filtering, antenna length, the DSP chip or all of the above. It’s there, but sometimes not worth straining to listen to. I haven’t tried an external antenna as of yet. The G5 doesn’t feature the USB / LSB option, so the Digitech is easier to tune. Full disclosure, SSB was never a deal breaker for me and I’m satisfied with what I can hear.

AIR Band

A touch more sensitive than the Skywave here. As all my testing is done strictly from the whip – that might be the advantage.

General

I have to say the build of this radio is very impressive. Buttons are very firm and responsive. The tuning knob is superb. As the weakest physical part of the Skywave, the AR1780’s knob, and its fine tuning counterpart, are spot on perfect. Nothing sloppy here.

Battery consumption (4 AA) seems above average, although not super-impressive. It’s hard for me to analyze at the moment as I’ve been playing with this radio constantly. I probably take more notice when I’m replacing 4 instead of 2 and may eventually jump over to rechargeable AAs. Interestingly, I took the 4 batteries I had worn down just one notch in the AR1780 and stuck them in a Sangean PDR-18. The meter on the PDR-18 showed only one bar or less.

The Skywave gives you 10 pages of 10 memories, the AR1780 gives you 50 pages! Even without explanation in the manual, setting these up are very intuitive.

The dial provides plenty of information. Curiously, if tilted while off, there are indicators for Music, Voice, Snyc, DAB & WB. While none are employed by the AR1780, perhaps there’s something else in the works!

What I find annoying

The display defaults to the temperature or the alarm. If you use signal strength or time during operation, it defaults to temp when you turn it off. Both of my Tecsuns will let you set display for both radio on and off. It bugs me most because holding the radio always sends the thermometer up by 10-12 degrees!

It takes a good 3 seconds to power up or switch bands. I’ve heard of other radios having this trait, but this is my first experience. And this action does use a bit of power because switching bands, not the dial light, will show the first signs of battery wear. (Again, I’ve had no issues with severe battery draw and compare 4 alkaline usage with my G5.)

The Skywave has spoiled me with its super-fast scanning. The Digitech is similar to most Tecsuns. I’ve noticed them all skipping segments on the SW band.

I hear a difference between FM stereo and monaural from the onboard speaker. This is the result of a right or left channel only feed to the speaker when the radio is in stereo. The Grundig Mini 100 did this and without a mono setting, it drove me crazy. I like to see the stereo indicator, but it looks like the AR1780 needs to be set in Mono when listening to FM through the speaker.

There are a number of general traits that the AR1780 shares with the Skywave that I would have preferred to be more like the CC Pocket:

  • I prefer a lock switch over a long-press lock button.
  • When you switch to a different page on the Pocket, it only changes that band and stays on the current frequency. Both the Digitech and Skywave switch over all bands to that page number.
  • One last minor annoyance (getting very picky here), the dial light seems to flash when you turn the radio off. The Pocket doesn’t.

OK, the bad

As a portable / travel radio, I can’t image why there is no pouch!

Add $5 and provide something to protect this in the go bag. At least this problem can be remedied. A pouch from the Sangean ATS-606 fits perfectly.

But the biggest flaw I found (and this may answer the power consumption others have noted) is the light continues to function in the locked position! All buttons are disabled, but press anything and the light comes on. I can imagine packing this radio and as it gets pressed against something else, the light remains on until the batteries are drained. A major design error here.

Conclusion

I’m more than impressed and extremely happy I made this purchase. I have no doubt this radio will be a primary travel companion. Since I always take a few on the road, surprisingly this won’t displace the Skywave. (I really enjoy that radio), but rather the veteran Grundig G5. While still considered one of my favorites, the Digitech provides as much performance and a few more features in a smaller package.

If I were choosing between the Digitech AR1780 and the Skywave SSB – that would be a touch choice. As I mentioned before, SSB has never been a deal breaker during travel and I love the original Skywave as is. Portable means smaller and the Skywave is the perfect size. I use the weather band more than LW, but the fidelity on the AR1780 is absolutely superb.

And while I’ve read the Skywave SSB is going through initial run growing pains, CCrane has been stellar when it comes to customer service and final product. They’re radio geeks like us – Digitech is simply a badge on a product manufactured by another company. (Jaycar seems like decent people.) Bottom line – let’s see how the Digitech is holding up after 2-3 years of usage.

I treat my radios like babies, but I’ve seen most wear down with unresponsive buttons, scratchy volume or fading displays. In fact, the only two grizzled veterans still operating at 100% are my Grundig G6 and Tecsun PL-360. Even my 7600GR’s volume is failing.

Worth it so far? Absolutely – without a doubt. Any future quirks, discoveries and disappointments will be shared.

Jack, thank you for sharing this excellent review!

I couldn’t agree with you more–the AR-1780 must have the best on-board audio of any compact shortwave portable I’ve tested. As you state, what makes it stand out is the fact that audio is wonderfully balanced across the bands. And what better way to check mediumwave audio? Why Zoomer Radio (CFZM) of course! One of my favorite night time catches. 

Thanks for the note about switching FM to mono while listening via the built-in speaker. I don’t believe I had tried that yet.

And, like you, I find the active backlight during keylock such an odd behavior. I actually opened one of my travel bags during the holidays to find that the backlight was somehow fixed in the “on” position…with keylock engaged! I supposed the LED backlight has little effect on battery consumption because I imagine this the backlight was engaged for as much as three days, yet the battery still showed full bars. 

The AR-1780 is a quirky radio, but by golly it’s a good one and a great value! Thanks again for the excellent review, Jack.

Review of the Digitech AR-1780 portable shortwave radio

46 Replies

The following review first appeared in the October 2017 issue of The Spectrum Monitor magazine.

Earlier this year one of my readers in Australia noted the addition of the Digitech AR-1780 to the product offerings of the Australia and New Zealand-based retailer Jaycar.

One thing I’ve learned over the years is that there are few in-country sources of shortwave radios in both Australia and (especially) New Zealand. Jaycar, in a sense, represents what RadioShack and The Source have offered in the US and Canada––a more accessible electronics retailer with some shortwave radio selection.

Jaycar sells radios badged with the name Digitech. Unfortunately, none of Jaycar’s recent additions––and there have been a few––have been enormous hits among serious radio enthusiasts. The company currently offers five Digitech models: the AR1736 ($18.95 AUD), AR1721 ($25.95 AUD), AR1748 ($129.00 AUD), AR1945 ($159.00 AUD), and now the AR1780 ($129.00 AUD).

The Jaycar models are either very cheap sub-$30AUD digital portables, or pricier large portables with a form factor similar to the Grundig S350DL and S450DLX, or the C.Crane CCRadio-SW. The new AR1780 fits somewhere between––a compact portable that promises a compliment of features tailored for the radio enthusiast.

In this review, we’ll take a close look at the AR1780, starting with its feature set.

Operation Manual

The Digitech AR1780 ships with a small user manual. In fact, other than the hand strap, the user manual is the only additional item in the box besides the radio itself.

The manual is quite thin––slightly smaller in height and width than the AR1780––and only contains about eight front-and-back mini pages.  Although readable, it’s littered with grammatical and punctuation errors.  While a manual is certainly a welcome reference item with this feature-packed radio, this manual comes up short, lacking detailed explanations of features and even leaving some out altogether:  it does not, for example, offer any explanation on the use of the excellent squelch control, nor does it fully explain the station memory set on multiple memory pages––!  Rather unfortunate, as these features deserve a clear explanation.

First impressions

The Digitech AR-1780, like many DSP-based portables, includes a handy temperature display which can be toggled for Celsius or Fahrenheit.

I really appreciate the modest, portable form factor of the AR1780, so it had that going for it before I even opened the box. I travel with portable radios a lot, so the compact body of the AR1780 is very appealing. It’s not as compact as the C. Crane CC Skywave series, or the Grundig G6, but is much smaller than my Tecsun PL-660 and PL-880, or my Sony ICF-SW7600GR.

Comparing size: The Tecsun PL-680 (top), Digitech AR1780 (middle), and the C. Crane CC Skywave (bottom)

Unlike the radios mentioned above, the AR1780 does not include some sort of protective case or bag. I believe this is an omission for a radio aimed squarely at the traveler.

Fortunately, the plastic chassis of the AR1780 feels substantial enough. With the key lock engaged, the only likely problem that could arise from having no protective case is damage to the display, such as scratching.

The buttons all have a tactile feedback and seem to respond quickly enough, save powering up the radio, engaging the SSB mode, or changing bands, each of which takes a couple of seconds to engage.

I especially like the fact the AR1780 has, on the right, a dedicated multi-function tuning knob. One can turn the tuning knob to scan frequencies or press it to cycle through fast or slow tuning steps (or to turn off this knob’s function entirely).

The AR1780 also has a dedicated fine tune control––a tuning wheel just beneath the main tuning knob also on the right side of the radio (see image above).  The only odd quirk about this is that this is where most radios have a volume control. Being a creature of habit, many times I’ve inadvertently shifted frequencies when I simply wanted to turn up or down the volume! The volume control, meanwhile, is in the same position on the left side panel of the radio between the antenna and earphone jack.

Speaking of volume, the AR1780 can provide plenty of it-––almost room-filling audio––via the internal speaker. Best yet, I like its balanced fidelity: mellow, with notes of bass, but ample treble when listening at moderate volume. The audio response curve is almost ideal for such a small package.

Something else worth noting: the AR1780 fits nicely in the hand. In general, it’s a great size for portable listening.

Major bonus for a travel radio: the AR-1780 is powered by standard, accessible AA cells. Note that the frequency range information silk-screened on the back stand is incorrect–shortwave coverage extends up to 29,999 kHz.

On the downside, however, one negative I noted shortly after beginning use: muting between frequency steps. In AM mode, this is not as distracting as in SSB mode. Muting makes band scanning a more tedious and fatiguing experience. Unfortunately, in this era of DSP-chip-based receivers, it seems muting has resurfaced.

Also, as with many other DSP portables, you can often hear “input” noise when pressing buttons. In other words, if while listening to one frequency I decide to key in another, I’ll hear a little clicking or buzz in the audio as each button is pressed. This is a very minor annoyance since it only happens when buttons are pressed, nonetheless, I thought it worth mentioning. I often wonder if it’s a result of poor shielding, something from which similar models suffer.

Performance

Over the past two weeks, I’ve had the AR1780 on the air almost every day. I’ve compared it with a number of receivers, but mainly The C. Crane CC Skywave, The CountyComm GP5-SSB, and even the Grundig G6. Below, I break down my notes by band.

AIR band

Let’s start with the “bonus” band: the VHF aviation band.

I’m sure there a number of readers who’ll never use this band, but I am not one of them. Personally, I really enjoy listening to aviation traffic, especially when I travel by air. Since the advent of the AIR band on ultra-compact radios, I no longer feel like I have to lug an additional scanner or receiver just to listen to the local air traffic control; that’s a plus.

Performance-wise, the AR1780 seems to be equal with the CC Skywave on the AIR band. Like the CC Skywave, the AR1780 has a squelch control––a fantastic feature, indeed. Simply tune the radio to your favorite aviation frequency, press and hold in the tuning knob on the side, and then use the tuning knob to adjust the squelch level. I find level 3 or 4 works well.

Note that unlike the squelch on the CC Skywave, the squelch control on the AR1780 actually carries over to the shortwave band. If you have squelch set on the AIR band, then switch to another band where squelch isn’t needed, you will need to turn it off. I never use squelch on the shortwave or mediumwave/AM broadcast bands; normal fading (QSB) can trick the squelch to open and close while tuned to a frequency.

Another convenient feature: press and hold the AIR button to start an automatic scan of the entire band. It’ll run through the AIR band once, saving any active frequencies. This is an ATS feature, so only makes one pass.  I wish you could set it to continuously scan the aviation band in a loop, much as a traditional scanner would.

FM

The AR1780 does a fine job on the FM band. It easily received my benchmark FM stations and even decoded the RDS from one broadcaster about 110 miles from my home base.

When listening to marginal FM signals, the AR1780 can be set to mono mode instead of default stereo mode.

What’s more, the internal speaker is exceptional at handling music––reasonably full fidelity given the limitations of the speaker size.

Longwave/Mediumwave

I’ll be the first to admit that longwave is not an easy band for me to evaluate. Here in North America, there are so few opportunities in the summer to log trans-Atlantic longwave stations. Indeed, unless I’m travelling to New England or the Canadian Maritime provinces, I never try to do so on a portable. I leave TA longwave DXing to my SDRs and tabletops back home where I can listen with the assistance of a large antenna.

But when I travel to Europe, longwave is a must, so my travel radio needs this capability. Based on my ability to receive benchmark LW airport beacons, I’m going to assume the AR1780 will do a fine job receiving European longwave stations while in Europe.

Likewise, the AR1780 should serve you well for both daytime and nighttime reception on mediumwave. Fortunately, switching between 10 and 9 kHz steps is simple: with the radio powered off, simply press and hold the “0” button to toggle between these steps.

On longwave and mediumwave, you can also use SSB mode (both upper and lower sideband). This could come in handy to reject adjacent signal interference on MW.

Likely an oversight on the part of the manufacturer, you can even engage the squelch feature, though why you would on LW and MW, I’m not sure.

Of course, with the fine-tuning control, you can navigate both bands in 1 kHz steps should you desire.

In short: the AR1780 is adequately sensitive on mediumwave and likely on longwave, as well. I wouldn’t rely on it for any serious DXing, but for a travel radio, it will serve you well.

Shortwave

Being first and foremost an avid shortwave listener, I spent the bulk of my AR1780 evaluation time on the shortwave bands and I’m overall very pleased with its performance.

In almost all of my comparisons on the shortwave bands, the AR1780 had a slight edge over its competition, namely, the CountyComm GP5-SSB, the Grundig G6, and the C. Crane CC Skywave.

To be clear, though, it was a very slight performance edge which I think may be attributed to the fact the AR1780’s telescopic antenna is longer, giving it a bit of gain over its competitors. For example, the AR1780’s antenna is about 17.7 cm (7 inches) longer than that of the smaller CC Skywave.

Still, placed on a table and not held in the hand, the AR1780 was able to pull in weak signals better than its competitors. I also compared it with the the Tecsun PL-680––one of my most sensitive shortwave portables––and, not surprisingly, the PL-680 outperformed the AR1780.

Again, I should stress that the sound from the AR1780’s internal speaker is more pleasant to listen to for extended periods than that of its smaller competitors.

SSB

Single sideband reception on the AR1780 is pretty impressive for a radio in this price class. On my particular unit, I found that the fine-tuning control was almost always needed to budge the frequency a few tenths of a kilohertz, even when I knew a particular signal was exactly on frequency. My Grundig G6 always had the same problem––indeed, sometimes in SSB mode, I had to listen “up” as much as 2 kHz on the G6.

The fine-tuning control works very effectively in SSB mode, nonetheless. Audio is quite pleasant, although the noise floor is not quite as low as it is on my larger portables like the Tecsun PL-680, PL-880, and the new S-8800. In my comparison tests, the AR1780 was slightly more sensitive than the CountyComm GP5-SSB, and about equal to that of the Grundig G6.

In short? SSB is a welcome, capable addition on this compact portable.

Summary

Every radio has its pros and cons, of course. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions. Following is the list I’ve formed over the time I’ve been evaluating the Digitech AR1780:

Pros:

  • Display is clear and easy to read
    • Time is always present via display button
    • RDS info scrolls on lower line
    • Backlit display easy to read
    • Viewing angle good, save from top
  • Dedicated fine-tuning control (even on FM)
  • External antenna jack
  • 9/10 kHz selectable MW steps
  • Time set is simple
  • Adjustable bandwidth in AM and SSB
  • Decent battery life from four standard AA cells
  • Audio from the built-in speaker has better fidelity than other radios in this size

Cons:

  • No bag or carry case
  • DC input voltage is an odd 7V
  • Muting between frequency changes, especially annoying in SSB
  • Sometimes keylock activates backlit display permanently
  • Scan function on AIR band doesn’t loop, it’s an ATS pass only
  • My AR1780 had incorrect information silk-screened on the back regarding frequency coverage
  • Minor: sluggish response when switching bands or modes

Conclusion

Is the Digitech AR1780 worth the price?  I think so. For $129.00 AUD (roughly $103 USD), you’re getting a full-featured radio that is, by and large, a pleasure to operate. It has its quirks, but so do so many ultra-compact portables in this price bracket. It’s certainly worth considering if you live in Australia or New Zealand.

I’d like the AR1780 to be a little more refined:

  • No muting while band scanning in AM or SSB modes
  • A proper scan function to accompany squelch on the AIR band
  • Squelch that doesn’t carry over when bands are switched

What I do think is impressive for this price:

  • Overall smooth audio from the internal speaker
  • Dedicated external antenna port
  • Dedicated tuning and fine-tuning controls
  • Useful screen which displays time and even RDS information
  • Sturdy, relatively long telescoping whip antenna

These are features that make the AR1780 stand out among radios in its price class.

Is it a benchmark performer?  No. But it does the job rather well for the price, and frankly, I think I’ll use this during travel occasionally, even though I have several other smaller portables.

Why?  Well, for one thing, this radio has better audio fidelity from the internal speaker than most of my ultra-compact portables. When I’m in a hotel and listening to a local radio station or even a shortwave broadcaster that’s punching through typical hotel RFI, I’ll appreciate the richer, mellower audio. Many of my smaller portables are lacking in this respect, thus I usually end up listening through headphones.

In fact, the only thing this little receiver lacks for us here in North America is NOAA weather/Environment Canada radio frequencies––but it’s no wonder it’s not included, as it was never intended for this market. But I’m glad the step size on the AM broadcast band can be switched to our 10 kHz spacing, which makes it useful here in North America.

In short, the AR1780 has exceeded my expectations––though admittedly, it may be because it was my first experience with a Digitech radio and I had heard so many lukewarm reviews of previous models.

Regardless, I’m happy I paid a small premium to order this little rig from Down Under.

If you’re a radio enthusiast in Australia or New Zealand who wants the best performance in a portable, and doesn’t mind a larger radio, then do splurge for the Tecsun PL-660, PL-880, or Grundig Satellite. There is a dedicated Tecsun distributor in New South Wales and there are always, of course, retailers on eBay and one of my favorites, Anon-Co in Hong Kong.

And if you’d like to order a Digitech AR1780 outside of Australia or New Zealand, you can purchase from this eBay seller, as I did.

A review of the Tecsun S-8800 shortwave/LW/AM-MW/FM portable receiver

29 Replies

Earlier this year, Tecsun released its long-awaited newest large portable: the Tecsun S-8800 portable shortwave/LW/AM-MW/FM receiver.

Though I fully intended to buy a Tecsun S-8800 for review, our friendly Hong Kong-based Tecsun retailer, Anon-Co, sent an S-8800 to me before I could. I’ve worked with Anna at Anon-Co for at least a decade and have purchased numerous radios for review, not to mention as gifts for family and friends.  When she insisted to send it as a gift, I decided I would (gratefully) accept the unit.

I received the S-8800 on February 1 and promptly posted unboxing photos here on the SWLing Post.

My new Tecsun S-8800 had a serious problem, though––one that two early S-8800e adopters noticed as well––internally generated noises, also known as birdies. And while most receivers will have a few minor birdies scattered across the bands, this S-8800 hosted a whole chorus of them, overwhelming the bands and making use of the radio difficult.  Read through this post thread for details.

I contacted Anna at Anon-Co and she immediately notified Tecsun; as a result, they halted distribution of the S-8800.

Tecsun took the S-8800 to their engineering team, and I’m happy to report they’ve now eliminated the horrible warbling DSP birdies of the initial unit I received.

On the S-8800s since released, while there are still a few minor birdies across the bands (more on that later), they’re merely what one might expect to find on any receiver. In short, the S-8800 now in production is a functional receiver, and a contender in its class.

I’ve had the S-8800 for a few weeks now and have had time to put it through its paces. What I present now is a review of the re-engineered Tecsun S-8800.

First impressions

Tecsun S-8800 Front Ang

In the spirit of full disclosure, I must note that I’m not as avid a user of large portables like the S-8800. Personally, my preference is for smaller, full-featured travel-friendly portables, or else larger tabletop models.  I travel often and like to pack lightly, so I rarely reach for anything bigger than my trusty Sony ICF-SW7600GR, or Tecsun PL-880, and more often than not, I grab the ultra-compact Sony ICF-SW100 or C. Crane CC Skywave.

But to say that I never reach for large portables would be inaccurate. In fact, I use a Grundig GS350DL daily; it’s my analog kitchen radio. I rarely move the tuning dial (a good thing, since it unfortunately drifts) because it’s locked onto my in-house SSTran AM transmitter on 1570 kHz.

What large format portables like the GS350DL and S-8800 can provide that a small portable cannot is broad, rich, room-filling audio. In my world, good audio is an important factor in overall signal intelligibility.

The S-8800 chassis resembles several other receivers: the Grundig GS350DL, S450DLX, and more recently, the Field BT, just to name a few.

The body is made of a hard plastic (not rubberized) and feels rugged enough. The knobs and buttons also feel tactile and of comparable quality to the previous similar models noted above.  With the rechargeable batteries inserted, it weighs about 3 pounds 4 ounces (1.5 KG).

The backlit display is large and viewable from almost any angle––even at a distance.

The main encoder (tuning knob) has appropriate amount of brake for most listeners. It wobbles very slightly, but functions amazingly well. I prefer it over its large portable predecessors, especially the 350GL. There is no soft mute while tuning, so band-scanning is a fluid, almost analog, process.

Both the “Band Select” and “AM BW” knobs have soft detents that mark steps in selection. In the field, I noticed that these can occasionally skip an increment when the detent only moves one position or the knob is turned very slowly. This doesn’t really affect functionality in any way, but I thought it worth noting nonetheless.

Like previous similar models, the S-8800 lacks a built-in keypad for direct frequency entry. That would be a major negative for a radio in this price class if the S-8800 didn’t come with one invaluable accessory:  an infrared remote control.

Infrared (IR) Remote Control

The Tecsun S-8800 ships with a IR remote control, and as far as I’m concerned, it’s great.

The remote feels durable, fits well in the hand, and the back has a place for it to balance on your index finger when holding…

But more importantly, the remote works quite well.  The controls are intuitive and the labeled buttons are quite easy to read. They’re also tactile and have a muted “click” response when pressed. Indeed, I wish my television’s remote was this well designed.

And the remote is quite useful, especially if you like listening from bed, from a porch, from the kitchen or dining room or den––or, in fact, from any space where you might wish to control the receiver at a distance. I believe its possible that every function of the S-8800 can be controlled with the remote––even the sleep timer!

Perhaps my dream remote for such a purpose would be backlit, but the S-8800’s remote is so simple to use, I’ve already nearly memorized where the buttons are located for nighttime use.

Operation Manual

The S-8800 ships with an informative operational manual, although this radio is intuitive enough that a seasoned radio listener will not need to reference it, save for advanced settings. Still, it’s written in clear language––with comparatively few English grammar errors––and the diagrams for both the radio and the remote are exceptional.

I referenced the manual several times to sort out ATS operation, saving/erasing memories, and to hunt down function shortcuts.

Features

The S-8800 is a feature-packed triple conversion receiver.  Here’s an abridged list of its features, focusing on those most radio enthusiasts seek:

  • Frequency coverage:
    • LW: 100 – 519 kHz (1 kHz & 9 kHz steps)
    • MW: 520 – 1710 kHz (1 kHz, 9 kHz and 10 kHz steps)
    • SW: 1711 – 29,999 kHz (1 kHz & 5 kHz steps)
    • Note in SSB mode on LW, MW and SW, tuning steps are 10 Hz and 1 kHz.
    • FM: 64 – 108 MHz (selectable for various markets: Russia, The Caucasus, Caspian/Black Sea regions, Japan, China/Europe, and North America)
  • Modes: AM, FM, SSB
  • Variable filter widths
    • AM: 6, 4, 3, and 2.3 kHz
    • SSB: 4, 3, 2.3, 1.2, and 0.5 kHz
  • Digital Signal Processing (DSP)
  • Antenna gain selection: DX/Local
  • External antenna connections: both BNC (SW and FM) and a high-impedance port (LW, MW and SW)
  • Both 9 and 10 kHz spacing on mediumwave
  • Dedicated fine-tuning control
  • Auto Tuning Storage (ATS)
  • 650 station memories
  • FM stereo/mono
  • Backlit LCD display
  • Treble and bass tone controls
  • RCA line-out audio
  • Full-featured clock, alarm and sleep timer
  • IR remote control
  • Two 18650 lithium cells (included) that can be safely charged internally via USB

Wishlist? The S-8800 feature set is pretty comprehensive, but my dream large portable would also have synchronous detection and an RF gain control, though the latter is not common in the world of portable radios.  Fortunately, the S-8800 does have a local/DX gain toggle.

I’m sure some enthusiasts would also like to see Bluetooth connectivity as on the Eton Field BT, but I personally don’t miss it. I like to keep my HF portables free from anything that could potentially raise the noise floor.

With the exception of synchronous detection, the S-8800 has a solid, comprehensive tool set.

Performance

Over the past two weeks, I’ve had the S-8800 on the air almost every day. I’ve compared it with a number of receivers, but mainly its smaller sibling, the popular Tecsun PL-880. Below, I break down my notes by band.

FM

As is typical with my shortwave portable reviews, I spent less time evaluating FM performance on the S-8800.

With that said, I did compare the S-8800 with the PL-880, PL-680 and CountyComm GP5-SSB and a few other portables. The S-8800 found my benchmark weaker broadcasters with ease.

Here’s a short video demonstrating FM performance with a broadcaster over 100 miles distant:

AM/Medium Wave

I’ve had more inquiries about S-8800 mediumwave performance than I’ve had about any other radio I’ve recently reviewed. Why?  Well, for one thing, some radios in this particular portable format perform quite well on mediumwave––the C.Crane CCRadio-SW, for example, comes to mind.  Also, the S-8800’s large front-facing speaker lends itself to superb AM audio.

Unfortunately, mediumwave is not the Tecsun S-8800’s strong suit.

I did extensive testing, comparing it with much smaller portables: the Tecsun PL-880, the Sony ICF-SW7600GR, the Digitech AR-1780, the CC Skywave, and even a pre-production CC Skywave SSB. All of these portables had better sensitivity on mediumwave.

I posted the following representative video a couple weeks ago in a post:

To reiterate from my previous post, comparing any modern radio with the Panasonic RF-2200 on mediumwave is hardly fair.  For one, the RF-2200 has been out of production for a few decades.  For another, the RF-2200 has a large rotatable ferrite bar antenna that provides excellent gain. The RF-2200 simply wipes the floor with all of my modern portables, as their ferrite bar antennas are but a fraction of the size.

To my ear, the S-8800’s  mediumwave band seems noisier than its competitors. Perhaps this is why it struggles with marginally weak stations.

Here’s another comparison with the PL-880––this time at a totally different location:

With that said, when tuned to a local AM broadcaster, the S-8800 really shines. It produces rich audio which can be customized with bass/treble tone controls and by changing the AM filter width.

I also hooked up the S-8800 to my large horizontal loop antenna. This certainly did improve MW reception, but not as dramatically as I hoped.  Additionally, it seemed to be very sensitive to RFI in my shack even when hooked up to the external antenna.

If you took the S-8800 to the field, added a decent inductively-coupled magnetic loop antenna, no doubt it would improve mediumwave reception, but I still doubt it would come close to the RF-2200 in performance.  As long as I own the latter, I wouldn’t be motivated to do so.

Due to my schedule over the past few weeks, I’ve had precious little time to test the S-8800 on mediumwave at night, but some quick air checks proved performance was consistent with daytime testing.

I am pleased to report that no receiver overloading was observable during testing.

In short: if you’re only considering the S-8800 for mediumwave DXing, you should look elsewhere. I would suggest a dedicated AM broadcast receiver like the excellent CCradio 2E,  a vintage Panasonic RF-2200, or perhaps a used GE Superadio.

LW – Longwave

I’ve spent less time on longwave than I have on mediumwave and shortwave.

With that said, the S-8800 was able to receive our local airport beacons at night with relative ease. I was not able to catch any transatlantic longwave broadcasters, but that’s no surprise as it’s almost impossible on even my commercial-grade receivers during the summer months here in North America.

As I said regarding the mediumwave band, I suspect there are much better radios out there for the longwave enthusiast.

SW – Shortwave

At the end of the day, I believe the Tecsun S-8800 was designed with the shortwave and amateur HF radio enthusiast in mind.

The S-8800 has gapless HF coverage from 1,711 kHz to 29,999 kHz, can be used both in AM or Single Sideband (selectable LSB/USB), and has adjustable bandwidth filters tailored to AM broadcast and SSB/CW (ham radio/utility/pirate) reception. The filter widths are well-chosen for each mode: 6, 4, 3, and 2.3 kHz on AM; 4, 3, 2.3, 1.2, and 0.5 kHz on SSB.

It also has a dedicated fine-tuning control that adjusts steps based on the mode.

All of these are desired features for the HF radio enthusiast.

I’m happy to report that the S-8800 is a very capable shortwave receiver, perhaps even one of the best portables currently on the market.

In every comparison test I made on shortwave, the S-8800 outperformed each of its competitors.

Check out the videos below and judge for yourself:

I was pleasantly surprised by the audio in SSB mode and by how well the filters seem to work. Note in the video the warbling sound as I adjust the fine-tuning control on the S-8800.  But it’s actually only present as I adjust the fine-tuning control; I noticed no stability issue once on frequency.

External antenna

Since the S-8800 has a handy standard BNC connector and high impedance AM antenna socket on the back, I hooked it up to my large horizontal loop. In my testing, it handled that antenna’s gain very well and I was most impressed with the performance.

The front end seems to be robust, and selectivity––which is excellent––was not compromised by my antenna. I was able to pull apart two broadcasts with only 5 kHz of separation that were both quite strong. The S-8800 locked onto the stronger of the two stations with ease. When tuned to the weaker station, I used SSB reception on the upper sideband to ignore the noisier lower sideband which was buried in the adjacent signal. Once I zero-beated the signal, it sounded quite good.

Final thoughts about shortwave performance

Perhaps what the S-8800 has going for it on shortwave is a combination of very good sensitivity, excellent selectivity, and a feature all too often overlooked: good audio fidelity (via the internal two-watt speaker).

The AGC (auto gain control) is actually fairly stable on the HF bands (less so on mediumwave). Like the Tecsun PL-880, the AGC has a soft hiss response when the signal fades below the AGC threshold. While I’m not crazy about this, I must confess that it is pretty easy on the ears when fading is pervasive.

I did note one quirk that could annoy those wishing to copy narrow SSB or CW. If the filter bandwidth is set to .5 kHz and you’re listening to a marginal CW signal, the AGC sometimes mutes the receiver during CW dead space. It equates to very unstable audio with audio levels jumping around wildly. This happened more often when I was copying moderate to weak CW signals. I’ve even noticed it when listening to SSB ham radio conversations, but mostly in the narrow bandwidths. I usually keep the filter set to 2.3 kHz or higher and it hasn’t been a problem at these settings. It’s worth noting that I have observed the same AGC behavior in my PL-880 at times.

The S-8800 ships with two rechargeable lithium cells which provide hours of listening time from a full charge.

I never encountered overloading from local AM broadcasters on the shortwave bands, with the caveat that I never tested the S-8800 in an RF-rich urban market.

One thing I have noticed in general about the S-8800 is that it seems pretty sensitive to RFI indoors (electrical noise in the home, office, etc)––more so than my Sony ICF-SW7600GR, for example. If you live in a noisy environment and never plan to use an external antenna or take the radio outdoors, you might think twice about the S-8800.

Birdies

I’m pleased to report that Tecsun did properly address the “birdie” issue I mentioned at the beginning of this review. Still, like most receivers, the S-8800 does have some birdies across the bands. These birdies are well within the norm for such rigs:  a relatively stable heterodyne sound. I made a short video to illustrate what I mean when I talk about a birdie:

I spent one afternoon carefully mapping out all of the birdies I could find across the longwave, mediumwave and shortwave bands.

Here’s what I mapped:

As you can see, there are no birdies in the middle of sensitive areas like broadcast bands, amateur radio bands, etc. A good report, in my book.

Note that while tuning through the shortwave bands, I used 5 kHz steps. I suppose there’s a possibility I might have missed very weak birdies doing this, but any strong birdies would have been received and noted within the 5 kHz window. On LW and MW, I tuned in 1 kHz increments.

Summary

Every radio has its pros and cons, of course. When I begin a review of a radio, I take notes from the very beginning so that I don’t forget my initial impressions. Following is the list I formed over the time I’ve been evaluating the Tecsun S-8800:

Pros:

  • Brilliant audio fidelity from built-in speaker
  • Dedicated AM bandwidth and fine tuning controls
  • Excellent, bespoke IR remote control
  • Capable SSB mode
  • Excellent shortwave sensitivity (see con: mediumwave)
  • Excellent shortwave selectivity
  • Excellent FM performance
  • Easy-to-read backlit LCD digital display
  • Remote control beautifully equipped for full radio functionality
  • Included 18650 rechargeable lithium batteries power radio for hours

Cons:

  • Lackluster mediumwave performance (see pro: shortwave)
  • No synchronous detector
  • No direct keypad entry (Pro: Remote control has excellent keypad entry)
  • Can’t charge and listen at the same time–not designed for AC operation
  • No backstand
  • Line-out audio level is a little high (hot)
  • When in narrowest SSB filters, AGC can’t reliably handle audio/signal changes
  • Slight “warbling” sound while using fine tune control in SSB mode
  • No RDS display on the FM band

Conclusion:

As I’ve already mentioned, if your primary use of the S-8800 is for mediumwave or longwave DXing, you should look elsewhere. While the S-8800 will serve you well with local AM stations, it will not dig signals out of the noise like other better-equipped AM receivers.  The GE Super Radio, Panasonic RF-2200, or CCRadio 2E are much better options.

But if you’re primarily a shortwave radio listener––? I think you’ll be pleased with the S-8800.

To my surprise, the S-8800 consistently out-performed my beloved Sony ICF-SW7600GR and my PL-880. I fully intend to compare it with other portables in the coming weeks and post the videos here on the SWLing Post. [I will update this review with any other findings.]

I did not mention this in previous posts, but the first S-8800 I received in January––the one with the birdie-chorus problem––also outperformed my other modern portables on shortwave. In part, I feared that when the Tecsun engineers addressed the birdie issue, it could have a negative impact on overall sensitivity. I’m happy to report that it did not.

What’s more, I realize that larger portables do have a place in my life.  You might have noted that I did all of my review testing and preparation outdoors, mostly in a nearby national park. I do this, in part, to insure I’m far away from any RFI, but also I simply love playing radio outdoors.

And the S-8800 was a pleasure to tune and use in the field. I really like the large encoder and find that the multi-function knobs, tone controls, volume, and other buttons are well-spaced–I believe I could operate most of this receiver’s functions with gloves on in the winter. And again, there’s that excellent remote control…

Is the S-8800 a good value? Let’s talk price

Only yesterday, Anon-Co announced the price of the Tecun S-8800: $268 US with free shipping to the US.

This review was in final draft form two days before I learned the price from Anon-Co. I had assumed the price would not be released for another week or two at least, thus I made a few predictive statements that I’ll now quote here:

I understand that the S-8800e is being sold in Europe for 339 Euro, roughly $400 USD, plus shipping. There is no way I’d pay that price; it’s simply too much.

If the price exceeds $300 US, I’d suggest careful consideration, as the S-8800 price would be venturing into the realm of used Sony and Panasonic benchmark portables.

But.  If this radio should be sold for less than $250, or even $200…?  Being primarily a shortwave radio listener, I would certainly buy this radio for that price.

In the end, the price is $18 higher than the $250 I mentioned in my review draft, but I assumed shipping would be tacked on to that price. So $268 ended up being pretty close to the mark.

So I believe the Tecsun S-8800 hovers at the top price threshold of what most radio enthusiasts would be willing to pay for a portable.  At $268, it’s over $100 more than the excellent PL-880 and only $20 less than the Tecsun S-2000. And for radio enthusiasts outside the US, it sounds like shipping will be added to the $268 price. I expect European consumers will pay a premium due to embedded (and required) sales tax and customs handling fees.

Nonetheless, I would still consider purchasing at the $268 US mark because of its shortwave performance, ability to connect external antennas, audio fidelity, and the included IR remote control.

I would like to see the price lower than $268. If the price were nearer the $200 mark, it would be a no-brainer––this radio would likely fly off the shelves, and I’d strongly suggest purchasing.

Perhaps, with time, the S-8800 price will decrease. In the meantime, if you have the budget, I believe the S-8800 would make for a nice field companion, pulling weak DX out of the noise with excellent audio fidelity to boot. It’s already been a great field companion for me…and, I’m sure, will accompany me into the field again.
