Tecsun’s S-8800:  Is This All The Radio You Will Ever Need?

These days, we who still derive enjoyment from listening to shortwave broadcasts, be they larger international broadcasters or smaller stations that remain on the air against all odds in the Internet age, also enjoy using the many types of radio receivers that enable this activity.

One of the cruel ironies is that today’s technological advances have made possible the kind of worldband radios (the term that first came into wide use way back in the 1980’s) that years ago we could only dream of, be they full communications receivers or portable receivers.

Having begun my own DXing/SWL career in the late 1960’s, and pretty much maintained my hobby activities over the decades, I have used pretty much every receiver that ever existed, from tube radios to today’s latest DSP wonders.

I have a soft spot for classics from SONY — my list of portables today includes the fantastic SONY ICF-SW77, SW-07, SW-55s and SW-100.  Panasonic is represented in my portable collection by the wonderful RF-B65.

Only in recent years did I decide to test the main higher end portable offerings from Tecsun:  the PL-660/680, and PL-880. What I discovered, as have most people who own the Tecsuns, and similar receivers such as the XHDATA D-808, are the wonders of DSP chips and the great flexibility they provide, such as multiple selectivity options, along with excellent sensitivity.

Though it’s been on the market for going on three years now, one of the receivers I had not been able to test was the Tecsun S-8800.  There are quite a few reviews already online. Some go into extensive detail in describing the plus and minus points of the radio.

With so many people having already assessed the radio — and most of them in fairly glowing terms — I won’t repeat a long list of technical specs, as you can find those in other reviews, and on the site of Hong Kong-based Anon-co, which is probably the main seller of the S-8800.

Headline

The S-8800 is arguably the best multi band radio portable among portable category offerings on the market today.  It combines superior audio delivered from its superb front-firing speaker, with equally superb sensitivity (triple conversion), and multiple selectivity options, with an amazingly professionally-executed remote control.

I used the S-8800 in a number of physical locations, from public parks where I hoped to avoid high noise levels, to my back yard where noise levels are, unfortunately, quite high.  I have compared the S-8800 to a number of portables in my collection, including: SONY ICF-2010, SW-77, SW-55, along with Tecsun’s 660 and 880, Grundig SAT-500.

Audio

Hands down, the S-8800 wins the audio competition when compared to pretty much every other radio.  Where the competition gets tight is with receivers such as the classic Grundig Satellit 500, and Tecsun’s PL-880.

Sensitivity

This is a TRIPLE conversion radio.  As everyone knows by now, Tecsun did not merely adopt the cabinet of the old Eton S350 but basically stuffed a hot rod racer into the cabinet of what was previously a mediocre radio at best.

Selectivity

Widely used in a number of radios these days, the S-8800 uses a DSP chip that is seen in a number of other receivers.  The best description I have seen so far is in the review by Jay Allen who notes that Tecsun “decided to utilize a combination of DSP (Digital Signal Processing) circuits along with traditional analog circuits . . .most of the AM/SW circuitry is PLL/analog along with the 1st and 2nd IF’s, while the 3rd IF is DSP.”  It appears that after a bit of a rocky period in the beginning when initial units suffered from images and birdies, Tecsun got it right.

Ergonomics

Much has been said about the fact that Tecsun decided not to include a keypad on the radio itself.  I too was skeptical. We have all become accustomed to keypads as standard equipment on portables.

Personally, I do a lot of my listening on the beach during vacations, and am used to being able to hold and operate the radio in such situations, so the thought of having to carry a remote control seemed uncomfortable at best.

However, the reality is that it’s still possible to navigate the shortwave, AM, and FM bands easily even without the remote — call me old fashioned, but I am from a group of older listeners who have most frequencies memorized anyway, so I know where I want to go to hear certain stations.

Tecsun hit it out the ballpark with the remote supplied with the S-8800.  It looks like something you would find with high end stereo equipment and clearly much thought went into making sure it can control every aspect of the receiver, from SW band slewing to selectivity, volume, readout — everything except BASS and TREBLE control, Timer/Alarm, and master volume (i.e. as other reviewers note, you have to set the on-radio master volume to a high enough level first, then use the remote to vary).

Power

The radio requires two 18650 lithium (Li-ion) rechargeable batteries, with individual indicator LEDS inside the battery compartment.  This choice is perhaps one of the most controversial aspects of the 8800. Among other things, 18650s usually receive more attention from airport security personnel if one is taking the radio on a trip — this is something everyone should keep in mind.  Any radio being transported on a flight these days is going to be subjected to added scrutiny, simply because almost no one uses radios anymore.

As for the power needs of the receiver, the 18650s seem to do a good job and last quite a long time, even days.  Included in the box is one of those white USB charger blocks — quite small and convenient. I usually travel with separate 18650 chargers, the kind used with high end flashlights, so having spare sets of charged batteries is not a problem.  But if both 18650’s in the Tecsun are drained, the radio definitely needs to re-charge to a minimum level required for operation.

As I write this, I plugged the S-8800 into a wall outlet (a blue LED indicator on front indicates charging mode) and I was unable to use the radio as the battery level had completely zeroed out.  Also keep in mind that the USB charging brick throws off EMI to other radios in the vicinity, and makes it impossible to use the S-8800 itself — there is just too much interference from the charging process to the radio’s receiving circuitry.

Comparisons

As mentioned, I compared the S-8800 with a number of other portables in my collection.  Each of these other radios, including the classics from SONY such as the SW-55 or SW77 have their strengths.  For example, the SW77 has the best implemented synchronous reception of any portable since the ICF-2010 along with superb sensitivity.  However, even the large speaker on the SW-77 was unable to compete with the S-8800. Only radios such as the older Grundig SAT 500/700 had the advantage when compared to the S-8800’s speaker, with the Tecsun PL-8800 close behind.

Receiving Comparisons

I decided to take the S-8800 out to my back yard for a receiving comparison with the receiver I consider to be among the top five best in what I call the small portable category (which is above the mini-portable category in which we find the SONY SW-100 and SW-07 and similar size radios).

In intensive use over the years, I have concluded that the Panasonic RF-B65 is probably among the hottest small portables.  With its famous amplified whip antenna, the 65 time after time succeeds in allowing me to hear stations that other portables struggle with (see this 3 radio comparison I posted a few years ago in which the B65 outguns the Sangean 909X and SONY SW-07).

Rather than produce several separate videos, I have combined one listening session comparing the S-8800 with the RF-B65.  It’s a bit long, so my apologies, but gives you an idea of how these two fine portables did going head to head.

Leaving aside the obvious superiority of the Tecsun where audio is concerned, the S-8800 competes well with the Pan RF-B65, often superior to the smaller radio, but sometimes inferior in one respect.

While there was nothing the S-8800 could hear that the Panasonic could not, signals seem to jump out of the S-8800 in a way that they did not with the smaller radio. However, there appeared to be an interesting difference when it came to the ability of each radio to deal with interfering stations 5 kHz above or below.

As shown in the video, the Panasonic was able to distinguish more clearly between a station on 9,650 kHz (Guinea) and a station 5 kHz above (in this case, Algeria via France, using 9,655 kHz) than the Tecsun, which seemed to struggle.  Indeed, at one point I was forced to attempt ECSS (Exalted Carrier SSB) mode to separate the two stations, whereas on the Panasonic, being the older and simpler radio design was an advantage in that the RF-B65 was actually able to more clearly separate the two stations by “de-tuning” from the center frequency.

One huge advantage of the S-8800 by the way is that there is a hidden software change that enables one to adjust SSB zero beat to zero or near zero.  This means that in theory using LSB/USB to improve reception is possible, though keep in mind that there may be some variation from unit to unit. So far, after performing the so-called ‘secret’ fix (among a list of tweaks discovered so far) my particular S-8800 appears to be able to zero beat LSB/USB with little or no variation between the side bands, pretty much up and down the SW bands.

Conclusions

For me, the S-8800 has turned out to be the biggest surprise of the last several years.  Coming seemingly out of nowhere, packaged in the cabinet of a receiver that was seen as mediocre at best, we have a triple conversion beauty (it seems to weigh almost nothing by the way) that provides pretty much every tool required these days to tackle what is left of shortwave broadcast reception.  It has superior audio, unless one compares to older Grundig and similar sets.

Drawbacks are quite few to be honest.  A case can definitely be made that using 18650 batteries was a poor choice by Tecsun.  This means, for example, that if you’re out on the beach or elsewhere for many hours, the only way to charge up the radio would be to use a separate phone battery charger rather than simply be able to slip in regular alkalines.  But then, I carry separate battery charge units already for my phone.

The big criticism that synchronous reception could have been included is also valid.  The same was said about the SONY ICF-SW55 — with synchronous reception, and a bit more careful design of the tuning circuit, that radio could have been a heavier hitter, a mini-ICF 2010, something the much more expensive SW-77 was designed to improve upon.

However, so far radios utilizing DSP chips have struggled when it comes to synchronous reception capability.  Indeed, the feature has ended up being discovered only as one of a number of ‘secret’ features. Only the PL-660 has a decent synchronous feature, but that radio is hobbled by limited selectivity options, while sync on the PL-880 is pretty much useless.

Finally, I have to say thank you to Tecsun for doing everything possible to avoid the dreaded ‘MUTING’ problem that has been seen on so many small portables.

As I found to my disappointment when using even the much-praised Eton Grundig Satellit, and even the C Crane Skywave SSB, this problem can be a killer for those of us who consider it absolutely critical to be able to hear EVERYTHING on and between frequencies.

So, the big question — would I recommend the S-8800?  As with almost everything, the answer to that is, it depends on what kind of a listener you are, and expectations.

From a performance perspective, if you are like me, a die-hard DX’er at heart who gets a kick out of searching for the last Peruvians on the air, the S-8800 should be more than sufficient.  If you’re both a die-hard DX’er and enjoy FM and AM, the 8800 should also be a perfect selection, since it’s been reviewed quite well in terms of medium wave and FM capability.

A personal note — for me, part of the fun of shortwave portables has been their ‘cool factor’.  I’m just one of those who likes to carry around complicated looking radios with lots of buttons. The SONY 2010, SW-55, SW-77s, older Grundigs all fit the bill.

I never thought the S-8800 or radios similar to it in appearance would.  So, for me it’s going to require a bit of a change, since the S-8800 looks like, well . . . it looks like a ‘toy radio’!

But it’s one hell of a toy-looking radio.  It’s a triple conversion monster packed in the frame of something that, at one point in the past, you might have considered getting for your kids (if they even knew or know what a radio is!).

As many of us are at this point in our lives, I am also thinking ahead — to the day when my numerous premium Watkins Johnson and JRC radios, and a few boatanchors hanging around, will have to go because of downsizing.

When I’m 65, as the Beatles song goes — or more likely 85 or 90 — what will I be able to fit on a bedside dresser and use easily to tune in whatever is left on shortwave (if anything)?

The answer to that question is a radio that’s small enough and enough of a performer, preferably with a well-designed remote, to bring in anything that’s still on HF, MW, and FM.  With those needs in mind, the answer is already here, in the Tecsun S-8800.

[I want to express sincere thanks to Anna at Anon-co who responded quickly when I proposed a review of the S-8800 and supplied the receiver on which this article is based.  Anna was patient as my original plan to have a review in by September was delayed by unavoidable personal matters. Thanks also to Tom Witherspoon for getting the review up so quickly].

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.

Tecsun S-8800 Hidden Feature: Frequency display calibration

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following procedure for calibrating the Tecsun S-8800. Dan received this procedure from Anna at Anon-Co:

Apparently there is a “hidden function” through which you can manually calibrate the SSB frequency display. Please follow the below calibration steps to see if it helps:

1) Turn on the device and set it to USB/LSB.

2) Now press & hold the “AM NORM.” button until you see the backlight blink twice (takes about 2 seconds).

3) Now press & hold the “MEMORY” button, until a certain value is shown on the display, for instance “6829”. This example value refers to a frequency like “xxx68.29 kHz”.

4) If you noticed a frequency deviation of 0.05 kHz up/down earlier, then you can use the main tuning knob to do the calibration. In the above-mentioned example, you would turn the main tuning knob to adjust the value to “6824” or “6834”.

Wow!  Thanks for sharing this Dan!  That’s two posts about S-8800 hidden features in one day. A record for sure!  Readers: please comment if you know of other hidden features.  I’m compiling a full list.

Bill discovers a number of Tecsun S-8800 Hidden Features

Many thanks to SWLing Post contributor, Bill (WD9EQD), who writes:

I’ve owned a Tecsun S-8800 for about eight months and have come to enjoy it more all the time. It, along with my PL-880, have become my main work horses for shortwave listening.

The S-8800 is perfect on the desk connected to a wire antenna and the PL-880 is perfect for carrying around.

Since I knew of the hidden features of the PL-880, it got me thinking on whether the S-8800 had any hidden features.

A quick Google search turned up the following Web Page:

http://swli-05940-mi.blogspot.com/2017/03/tecsun-s-8800-hidden-features.html

I used Google Translate to get a rough translation and then spent some time testing the features out and also just pressing and holding buttons to see if anything else showed up.

Following is what I have come up with:

(Note: some of these are in the manual)

With the radio off

Toggle Longwave on/off: With the Radio OFF, Press & Hold 2

Toggle backlight permanently on/off: With the Radio OFF, Press & Hold 3  – Note that this means the light will be on even when radio is off. While the light does go out when radio is turned off, any operation of a control will turn the backlight on and it will then stay on. Too bad they just didn’t install a slide on/off switch. Plus I know of no way to turn the backlight on permanently without the remote.

Toggle Seconds display on/off: With the Radio OFF,  Press & Hold 8

Displays “0888”: Maybe this is version?: With the Radio OFF,  Press & Hold “Back”

Displays all segments of display: With the Radio OFF, Press & Hold “AM NORM” – Displays all segments of display. Press & Hold again to display “H802”

With the radio on in FM mode

Displays “75US”: With the radio ON, Press & Hold 5

Squelch Setting: With the radio ON, Press & Hold 9 – Range 0-5. Use Tuning Knob to set. Press 9 again to set.

With the radio on in SW/AM mode

Toggles Extended functions on/off: With the radio ON, Press & Hold 4

With extended functions on:

Press & Hold 6 – Toggles DNR (Dynamic Noise Reduction) on/off.

Press & Hold 9 – Squelch Setting. Use Tunng Know to Set. Press 9 again to set.

Squelch ranges:

MW: 0-40

MW with USB/LSB: 0-30

SW: 0-25

SW with USB/LSB: 0-30

So far that’s all I’ve been able to find. Has anyone else found any others?

Post readers: please comment if you’ve discovered other hidden features on the Tecsun S-8800! I’ll compile a complete list and post it separately.

Troy compares the Tecsun S-8800 with the Grundig Edition Field BT

Many thanks to SWLing Post contributor, Troy Riedel, for producing this excellent comparison of the Tecsun S-8800 and Grundig Field BT “lunchbox” radios:


The Lunchbox Showdown

by Troy Riedel

I have been watching with interest all of the information & reviews of the new Tecsun S-8800. Frankly, I was especially interested in how it would compare with the other “lunchbox” SW radio – the Eton Grundig Edition Field BT (the Digitech AR-1748 lunchbox radio is also available in AUS for approximately $207US shipped). As I contemplated which lunchbox to purchase, I put together the following Excel comparison table of the S-8800 vs. the Eton Field BT to assist me in making my decision:

Yes, the S-8800 without a doubt has more features than the Field BT.  However, the S-8800 is slightly more than twice the price of the Field BT ($268 vs. $130)!  Does the performance of the S-8800 equate proportional to the price difference?

Shortly after I made my Excel comparison table, Thomas published video comparisons of the S-8800.  I very much appreciated the review and video comparisons that pitted the S-8800 against several popular portables.  It gave me a baseline to set my expectations.  However, those videos didn’t answer my question: “should I purchase the S-8800 or the Field BT”?

I contacted Thomas and I told him “we need an S-8800 vs. Eton Field BT” video comparison so SWL’ers have a true lunchbox vs. lunchbox comparison!  I volunteered to purchase an Eton Field BT and have it delivered to Thomas for him to compare the two (after which he would forward the Field BT to me).  After he hesitated, I replied: “what if I buy the Eton and we meet in North Carolina to compare them together”?  Fortunately Thomas readily agreed and I made the 6.5-hour journey from Southeast VA to Mount Mitchell State Park for the Lunchbox Showdown (864-miles roundtrip on my odometer)!

Thomas and I had a limited amount of time.  I arrived at noon.  Thomas and I had 8-hours … and that included time for Thomas’ Parks On The Air (POTA) Activation, our S-8800 vs. Field BT comparison, we had to eat (it was a long drive for me!), and Thomas brought many other toys so we had to carve out time to “play radio” (and I can’t drive 400+ miles to Mount Mitchell and not walk to the summit of the highest point east of the Mississippi River!).

Luckily conditions were as ideal as I have ever seen them (evidenced by the fact Thomas made contacts from TX to the Azores with his Elecraft KX2).  So please keep in mind, what follows is in no way a complete comparison.  And to be clear, it was never my intention to review either receiver (there are many people more competent than I am that have already done this – Thomas among them!).

My interest re: these two models is primarily limited to each’s shortwave performance (I use a Sangean PR-D15 and a Grundig YB400 for AM DX, I prefer my Sangean PR-D15 for FM and I own 12 shortwave receivers).  Thus our goals were to find and compare multiple representative SW signals.  Thomas is obviously familiar with local AM stations in the area that he uses in his comparisons, thus we sought out a few AM signals (I recorded one to illustrate one huge difference that we both perceived in the two radios).  Due to time, hunger, and eventually darkness we had to call it a day at 8 P.M.

I used my iPhone 6S to record the following comparisons.  This was the first time I recorded shortwave signals.  In retrospect, I wish I had made the recordings longer but at the time I was unsure of how much memory each recording would used, how much time it would take to upload, etc., so I kept everything at 1-2 minutes.  As you will see, I recorded nearly all of the signals with the backlight off.  You’ll see me reaching in, on Shootout 5, to tune off frequency – then back on – simply to show how the backlight would/or would not affect the weak signal on the Field BT (you’ll also see that it’s harder, outdoors, to read the Eton display without the backlight vs. the clearer Tecsun S-8880).

The Eton Field BT has its own SW RF Gain (a huge bonus) and you will see me reach into the field of view once or twice to fine tune the Field BT on weaker signals.  And if you’ve studied my comparison table, you’ll see that the S-8800 has multiple bandwidth choices whereas the Field BT only has Wide & Narrow settings.

You will see me occasionally change the BW on both.  I preferred not to speak during the videos as not to mask the audio of the signal thus I will set-up the specifics of each video with each individual link to my new YouTube Channel, SW Hobbyist, that I set-up to host these (and hopefully many future SW-related videos to include radio recordings & antenna comparisons).

General Conclusions

Thomas and I both felt that the AGC of the Tecsun S-8800 was very slightly better (more stable – absolutely no “chug”) than the Eton Field BT (again, a very subtle difference). We both liked the sound of the Eton Field BT much better – it was crisp, full and just seemed to “pop” through its grill (see Shootout #7). The huge thing we both disliked with the Eton Field BT is its tuning dial. Yes, it has Q-Tune so one can jump from 5000, 6000, 7000, etc., with the push of a button but the tuning dial (even in “Fast” mode) is painfully slow and deliberate (dare I say horrible in comparison to the S-8880?). We both love the fact the S-8800 has a remote. But even without the remote, the S-8800 was much more pleasurable to manually tune.

Not to speak for Thomas, but I believe we generally felt [overall] that the SW signals were essentially close enough to call even … the edge to the Tecsun on a couple and the edge to the Field BT on a couple of others (I specifically remember us both commenting on an Arabic language broadcast from Radio Saudi Arabia where we both felt the Field BT was a very clear winner – that was one of the signals that I did not record). The better “sound” of the Field BT’s speaker may have influenced our opinions – a sound that was markedly better on FM, better on AM, but a sound that was much closer on SW.

My final thoughts and conclusion: Radios are like vehicles. No one vehicle is best for everyone. Each vehicle has a specific purpose and each has a subset of features. I own a large travel trailer. I need and thus own a heavy-duty diesel truck to tow it. But I surely wouldn’t recommend my vehicle to somebody who only needs a commuter vehicle. That’s why we have everything from SmartCars, to sedans, to SUVs, to dually diesel trucks. The same goes for radios. Some people will absolutely need SSB, others may demand SYNC (neither of these units has this feature!) while others may choose a radio based on size (compact for travel or larger models with a large, easy-to-read display for desk or tabletop use). Until now, I felt the video comparisons we had for the S-8880 were comparing a truck to an SUV to a sedan. At least now we have a few videos of two lunchbox radios compared side-by-side. True, one (the S-8800) is fully loaded (in vehicle terms: a 4×4 with a touchscreen GPS and DVD entertainment system). But not everyone who requires a truck needs a 4×4 with GPS and DVD entertainment system. Some truck owners prefer the smoother ride from a 4×2 truck. I think that’s the best way to describe these lunchbox receivers.

Am I glad that I bought the Eton Field BT? For me – despite the cumbersome tuning of the Field BT – I feel the S-8800 is not worth 2x the price of the Eton (I got an even sweeter deal for my new, sealed box Field BT off eBay that was well under the $129.99 street price). But you can make your own decision, you can decide which features are must-have, and you can listen to these videos as well as the other videos that Thomas has already posted and determine if one of these lunchbox models are in your future. And because I learned so much regarding the video recording of shortwave signals (I suffered from tunnel vision while recording – not fully aware of what I caught and what I missed), I hope I can meet-up with Thomas again so I can do a better, more thorough job with a “Lunchbox Comparison, Deuxième Partie” (that French was for Thomas – I hope I got that correct!).


Thanks for putting together this comparison, Troy! It was great hanging with you last week on Mt. Mitchell!

If you’re shopping for either of these radios, you have a few options:

The Tecsun S-8800 is only available worldwide via Anon-Co at time of posting. Eventually, they will begin appearing on eBay. There are retailers in Australia and Europe also selling the model (Important: make sure you’re ordering a model from the latest production run which solves the DSP birdie problem in early units).

The Grundig Edition Field BT is available from a variety of retailers including Universal Radio, Amazon.comCrutchfield, Adorama and others.  Occasionally, like Troy, you can find excellent prices on the Grundig Edition Field BT via eBay.

Radio Day at Mount Mitchell State Park

Troy Riedel preparing the Tecsun S-8800 and Grundig Field BT for a comparison review.

Shortly after publishing my review of the Tecsun S-8800, SWLing Post contributor Troy Riedel contacted me and asked if I would consider comparing the S-8800 to the Grundig Field BT. Of course I was very curious how the $130 Grundig Field BT might compare with the $268 Tecsun S-8800, but I’ve got a lot on my plate at the moment and didn’t really want to purchase another large portable.

Long story short: Troy found a honey of a deal on a perfect Grundig Edition Field BT via eBay. He ordered it and we decided to bring the two radios together yesterday at beautiful Mount Mitchell State Park the highest point east of the Mississippi river.

Yesterday was an ideal day, too. The weather was picture-perfect, the park was (surprisingly) not too busy and propagation was the best I’ve experienced in weeks.

Troy left early in the morning and embarked on the 6+ hour pilgrimage to Mount Mitchell–I only live an hour away, so it was a casual drive for me. We met at noon.

Parks On The Air

After a quick lunch, we deployed my Elecraft KX2 with EFT Trail-Friendly antenna and made my first Parks On The Air (POTA) activation.

You might recall I was very active during the ARRL National Parks On The Air (NPOTA) program last year, but since then I’ve done few field deployments. It was great fun to get on the air again and do a park activation for the World Wide Flora & Fauna POTA program.

While we didn’t log a lot of stations, I was still impressed we worked stations from Texas to Quebec to the Azores. Not bad for 10 watts SSB!

Sure, I only worked a handful of stations, but this activation was essentially unannounced so chasers had no advance notice. No doubt, many more POTA activations are in my future! The bug has bitten!

Radio Fun

Except for a break to eat dinner at the park restaurant and a short hike to the peak of Mount Mitchell,  we played radio until about 8:00 PM. It was amazing, uninterrupted fun.

Troy spent a lot of time comparing the Tecsun S-8800 with the Grundig Field BT and made several videos. No doubt, he’ll post his thoughts and review in the near future!

Being a bit of radio geek, I couldn’t help but bring a few “extra” radios and accessories. Here’s what I packed:

We were a little disappointed to discover that both my Tecsun PL-680 and Grundig Satellit exhibited flaky behavior.

During my S-8800 comparison tests, a few weeks ago, I did notice that sometimes when I turned on the PL-680, it was absolutely deaf. Next time I turned it on, it worked fine. Yesterday, the PL-680 simply didn’t want to perform. I’m not sure what happened.

The Grundig Satellit, on the other hand, worked great, but sometimes if you touched either the antenna or even brought your hands near the radio body while tuned to a station, it would go deaf. You could correct this by tuning off frequency, then back on–still…very strange! It’s as if the AGC or RF gain were hanging up.

Have any Post readers experienced this before? I’ll look into the issue this week and reset both radios. Perhaps that will help.

A great “Mini DXpedition”

Thank you, Troy, for suggesting the meet up and for making the pilgrimage. It was great meeting you in person! I also thoroughly enjoyed watching someone else do comparison tests and exploring a new radio–Troy certainly has a knack for doing radio evaluations!

This has encouraged me to do more meet-ups, perhaps during my travels. Great fun!

Post Readers: be on the lookout for Troy’s comparison of the Grundig Field BT and Tecsun S-8800 in the coming days/weeks (no pressure, Troy!).
