Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
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:
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.
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 GreenHR-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.
For those who are interested, Tivdio passed along several coupon codes that SWLing Post readers can use to save money, should they decide to purchase the HR-11S:

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.
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 RadioShackand The Source have offered in the US and Canada––a more accessible electronics retailer with some shortwave radio selection.
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.
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.
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
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:
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:
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…
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.
With travels, solar eclipse events and family activities this week, I’ve had very little time to play radio.
Yesterday was a gorgeous day though, so I took the family to the Blue Ridge Parkway and (of course) packed a couple portable radios.
While we all enjoyed a picnic, I pulled out the AR-1780 with the intention of exploring its SSB performance and audio fidelity. I found an Islands On The Air (IOTA) activation with a decent pileup on 14,250 kHz.
Overall, I’m very pleased with the AR-1780 on SSB. The noise floor is pretty low, the filter selections are handy and the overall audio is comparable to slightly larger portable radios.
The dedicated fine tune control is quite handy, even though it’s oddly located on the right side of the radio (where one typically finds a volume control).
I’m putting together a short review of the AR-1780, but will need more air and comp time before I form any firm opinions.
For readers that have made it this far down the post, you might recognize a yet-to-be-released portable next to the AR-1780. Of course, I’m comparing it with the AR-1780 and its predecessor, but it’s not a production run unit (yet!), so I can’t comment on performance. Stay tuned, though, as I will be posting more in the coming days!
Many thanks to SWLing Post contributor, Steven Crawford, who shares the following:
I just wanted to take a moment and thank you for posting my inquiry on the Sony 7600GR. The post comments answered my question.
I also wanted to let you know your confidence in Ebay seller Anna and Anon-co continue to be well founded. Remembering your recommendation and wishing to pick up a Tecsun PL-360 as a spare to my CountyComm GP-5 SSB (Tecsun PL-365), I placed the order for it and a couple of other bits of Tecsun kit with Anon-co.
The order arrived in 6 working days to my Gulf coast Texas home, taking longer to travel from Chicago to my home than it took to move from Anon-co in Hong Kong to Chicago and clear customs.
I then had a question about the connecting cable included with the Tecsun badged, Tecsun / Kato / Grundig / Eaton, AN200 Loop Antenna. Posed through Ebay Anna promptly answered the question and added a photo of the cable to Anon-co’s Ebay listing for the AN200. It just doesn’t get better than that. You can continue to recommend Anon-co with full confidence from my perspective.
I picked up the PL-360 as a lower cost AM/FM/SW backup to the GP-5 SSB that would allow me to accept the risk of using the larger and heavier extended ferrite rod loop stick aftermarket antenna that garnered so much interest on your blog a year ago, before CountyComm warned of accelerated wear on the antenna jack. Happily the antenna works just as well on the PL-360 as it did on the GP-5 SSB.
Overall I am pleased with the PL-360.
The performance on AM and SW appears to match that of the GP-5 SSB (Tecsun PL-365) albeit with a slightly higher noise floor. Whether this is due to something akin to sample to sample variation or a direct result of inherent design differences between the PL-360’s Silicon Labs Si4734 DSP chipset versus the GP-5 SSB’s Silicon Labs Si4735 DSP chipset I can’t say. I can say the PL-360 with the included High Gain loop stick external tee antenna received my list of news gathering AM clear channel stations out to 900 miles during the night hours matching the GP-5 SSB. This list includes WGN, WBBM, WLS and KOA at the furtherest extreme. It also includes Mexico City’s XEEP 20kW at night at 800 or so miles. Switching to SW broadcast using the whip antenna and Tecsun’s / CountyCom EZTune system day or night the PL-360 and GP-5 SSB select and load the same stations within the PL-360’s slightly shorter SW tuning range.
Dittio on FM on the whip. Both radios snag my list of FM stations out to 60 miles.
For my purposes both are extremely close in performance to my Sony SW7600GR when using their supplied external loop stick. On AM if you combine one with the larger and heaver aftermarket loopsticks they will slightly outperform the 7600GR combined with a Tecsun / Kato / Grundig / Eaton, AN200 Loop Antenna. The Sony’s speaker gives it the edge in listening pleasure, but on earphones or plugs all three are close.
None of forgoing addresses the SSB performance as the PL-360’s chipset doesn’t offer that option.
I am pleased with the PL-360, Anna and Anon-co and I do thank you for posting my 7600GR inquiry.
I look forward to your blog.
Steve
Thank you, Steve! I’m happy to hear the 7600GR posting helped you–that’s what this community is all about…helping each other. Thanks to everyone who commented on that post.
And, yes, I think what surprises so many SWLs is the fact that Anna at Anon-Co actually knows Tecsun radios as well, if not better, than the manufacturer. I’ve only had good experiences working with Anon-Co and that’s why I recommend them so readily. Anna provides excellent customer service. (Click here to check out Anon-Co on eBay.)
I’m also happy to hear you’re enjoying the PL-360 and that you understand the risk of using the large ferrite bar on this radio series (PL-360, 365 and GP5 DSP and SSB). I use my antenna as well, though like you, very carefully.
I only use the large ferrite bar when I’m stationary and I’m careful not to put a strain on the antenna in any way; keeping it balanced and steady. In other words, you must handle it with kid gloves. If you take these precautions, I think your radio will enjoy expected longevity.
Thanks, again, Steven for sharing your review! I’m very pleased to hear you’re enjoying the SWLing Post!
Many thanks to SWLing Post contributor, Troy Riedel, for sharing the following report of his Sony ICF-EX5MK2 analog receiver:
A report on the Sony ICF-EX5MK2
by Troy Riedel
The consensus, ultimate, all-time AM DX radio is the Panasonic RF-2200. I do not nor have I ever owned this radio [yet!]. As such, I do not have that radio as a baseline and I cannot approach my review with that reference radio in mind. I own 10 or 11 portable Shortwave radios. Until now when I would AM DX, I would generally reach for my Grundig Yacht Boy 400 (~5.9” internal ferrite bar antenna). In my experience, the YB400’s Sensitivity is [overall] better than my Sony 7600GR, the Eton E5, and the Grundig G3 (just a few of the SW receivers that I own).
In this Sony review I also mention Tenergy batteries. I have no stake or financial interest in either Sony or Tenergy. I’m just a guy who enjoys SWLing as a secondary hobby – and let’s call AM DXing a tertiary hobby.
Part I: Description & Overall Impressions Prior to Use
History:
The Sony ICF-EX5MK2 is what I would call a legendary AM DX Radio. The radio is manufactured in Japan. It replaced the highly rated Sony ICF-55W (discontinued early-1980s and can command high prices on eBay). The EX5 was originally introduced in 1985 and it has been in continuous production since that year.
I’m not a radio expert, but I am not aware of any other AM receiver that has gone mostly unchanged for 32-years. The EX5MK2 has quite a loyal following among AM DXers. Its following and longevity is what I feel makes this receiver legendary.
The EX5 is smaller, but resembles the iconic Sony ICF-2010 shortwave radio. I do not own the ICF-2010, but it is my understanding that the EX5 shared similar internal circuitry with the 2010 until Sony ran out of component parts in the early 2000s (later versions of the EX5 and the EX5MK2 thus have more differences, under the hood, as compared to the ICF-2010).
The current version of this receiver being sold NEW is a “version II” that carries the model designation EX5MK2. The EX5MK2 was introduced in June 2009. So what are the differences between the EX5 and EX5MK2?
The original EX5 had analog TV Bands. Since Japan (like the USA) migrated to digital TV, the “version II” or EX5MK2 eliminated the TV Band and replaced it with limited shortwave. The shortwave on the current model has 6 crystal-controlled frequencies for the Japanese domestic service of radio Nikkei. As such, unless you live in Japan … or are in an area that might be able to coincidentally receive another SW station on one of those 6 crystal oscillator frequencies, you won’t be able to receive shortwave transmissions on this receiver (radio Nikkei 1: 3.925 MHz, 6.055 MHz, 9.595 MHz; radio Nikkei 2: 3.945 MHz, 6.115 MHz, 9.760 MHz). To be perfectly clear, all six frequencies are accessed via a switch setting to a 1, 2 or 3. There is no SW tuning, thus no other shortwave frequencies other than the six that are programmed into this radio can be accessed! Do not purchase this radio if you desire a shortwave radio!
Additionally, the EX5 & EX5MK2 both have SYNCHRONOUS DETECTION. However it is my understanding that the EX5MK2 has updated or improved this feature (I do not own the former thus I cannot say for sure).
Before Purchase Research:
In my research before purchasing the unit, I relied on an EX5 review by Gary De Bock as well as a review by “RadioJayAllen”.
Before a purchase I will typically download and read a receiver’s user manual. However since this is a radio manufactured for and sold on the Japanese market, the radio’s documentation is only published in Japanese. But this didn’t stop me!
Because my Japanese is not at a level to translate, I relied heavily on online language translation and I painstakingly translated the entire manual in MS Word and then converted it to a PDF (click here to download as a PDF).
Frankly, I found nothing earth-shattering in the manual. The EX5MK2 is an analog receiver with bare-bones features (other than the SYNC – more later). Unless you are unfamiliar with using SYNC and/or you do not know what it means to separate the USB or the LSB of a carrier signal, there is really no need for the manual.
Until recent times, this receiver was only available from Japanese sellers on their retail web sites, and via Japanese sellers on eBay & Amazon. However, Amazon now stocks the EX5MK2 in their US Warehouses and offers free, 2-day Prime Shipping. Amazon Prime is where I purchased my receiver. If one is interested in this receiver, my advice is to shop. I have never seen a receiver in which prices varied so wildly – and I do mean wildly – from approximately $119 to $249 USD! That’s crazy.
Reading reviews on Amazon were also very helpful in my purchasing decision. But I recommend you read individual reviews and not rely solely on the numerical overview. Why? You can tell by the review if the reviewer has knowledge of radios … there are several reviews of people complaining that the “shortwave feature is useless” – and yes, that’s correct (outside of Japan) but one should not buy the EX5MK2 as a general coverage shortwave receiver as it has AM DXing DNA in its core!
Specifications:
The radio is packaged inside a fairly non-descript cardboard box with no accessories other than an old-school carry strap for the radio and a complimentary set of four Sony C/R14 [disposable] batteries. Once these Sony batteries are expended, I will switch to Tenergy Centura “C” Low Self Discharge (LSD) NiMH Rechargeable Batteries. I am an occasional AM DXer and the Tenergy Low Self Discharge batteries keep 85% of their charge after one-year. I keep Tenergy LSD AAs in my infrequently used shortwave radios and I always know they will have a charge no matter how long they sit idle. Tenergy Centura LSDs are very reasonably priced, too.
The radio is 10” long/wide (10 3/8” to include the tuning knob on the right-side of the cabinet), 5 9/16” tall, and 2 ¼” deep. With batteries installed, it weighs slightly less than 2.5 lbs.
The optional AC Adapter is the Sony AC-D4L. The adapter, new, is only available in Japan and possibly via a pricey purchase through eBay. There are many listings on eBay and Amazon, of Chinese-made “For Sony AC-D4L” adapters but these are not the recommended Sony-made adapter. The Sony AC-D4L is highly rated and said to be a quiet adapter that does not produce RFI that could be introduced into the radio I do not know how well the aftermarket Chinese adapters function. Also, the EX5MK2 requires a negative center tip. For those of you that own a Sony ICF-7600GR, that radio requires a positive center tip. The AC Adapters for those two radios are – unfortunately – not interchangeable! I note this because at least one vendor that I encountered tried to tell me otherwise (he tried to sell me a positive tip 7600GR adapter and said it was the same adapter used for the EX5MK2 – not so).
Note: During the Field Test I found this receiver to be extremely RFI sensitive. I would only operate this receiver on batteries – but if I had to use an AC Adapter, I would only trust the recommended Sony-branded AC.
The EX5MK2’s analog slide tuning dial is linear, or rather the frequencies are evenly spaced across the dial (a nice feature that makes tuning a bit easier; admittedly I’ve become spoiled by digital tuning and I had to re-develop some patience with analog tuning). An additional, unique feature of this radio is the size of the analog slide dial window. It covers approximately 60% of the radio! The dial is filled with the precise locations of 48 domestic Japanese AM stations (in Japanese characters, of course). Obviously this won’t help anyone outside of Japan (but remember, this is a Japanese radio for the Japanese market thus I’m sure this feature is appreciated in Japan).
The EX5MK2 does not have a lighted dial. That is quite disappointing. The only lighted feature on the receiver is a red LED on the very top of the slide dial that illuminates on strong signals – but not all signals. At this price point, I feel a non-illuminated dial is a huge omission.
I have not opened-up the cabinet of my EX5MK2, but my research indicates this receiver has a 180mm (7.1”) internal ferrite bar antenna (there are photos on multiple Japanese language blogs where owners have opened the case and show the internal ferrite bar antenna next to a tape measure or ruler – you can find these sites via a Google Image search). The FM/limited shortwave whip antenna is 36 ¾”.
Since this is a Japanese market radio, it has FM Coverage from 76 – 108 MHz and AM/MW Coverage from 530 – 1600 kHz. My sample of the EX5MK2 has coverage up to 1650 kHz to the very top end of the tuning slide beyond “1600”. For those who need extended AM beyond 1600, this may not be the receiver for you.
As mentioned earlier, the most important feature of this radio is SYNCHRONOUS DETECTION with SSB that not only SYNCS or “locks on” to a signal, but also has two additional switch settings that allow one to separate the carrier signal in either the Upper Sideband/USB or Lower Sideband/LSB. This means there are three settings: NORMAL SYNC where the signal locks on to the entire signal, as well as a second LSB and a third USB setting that allows you to isolate a Sideband and listen to only the lower or upper parts of the carrier signal. This should help the receiver’s SELECTIVITY – hopefully I’ll find out when I Field Test this unit.
Summary of Part I: Initial Impressions
First, a little disclaimer: I am not a radio expert – not a “radiohead”. I am not an amateur radio operator. I know what I like and I know what works for me.
The radio appears to be well made. It has girth and weight like some receivers I’ve owned in yesteryear – it just feels like one is holding quality. The receiver is analog, not digital, and the tuning is tight and smooth (no slack in the tuning knob like some lesser quality analog receivers and turning the tuning knob results in a proportional movement in the tuning dial). The linear dial – which I found to be extremely accurate on my sample – makes tuning to a precise frequency a bit easier than I had expected. Despite this, I still found myself longing for a digital readout and I frequently used a digital receiver to verify a frequency if I didn’t hear a station I.D. after a reasonable amount of time.
At this price point, it is disappointing there is no illumination of the dial. But I have to remind myself that this receiver is essentially a 1985 model with minimal changes over the past 32-years.
But the big question remains: how does it perform and is it worth its price? Reported excellent AM DX performance – enhanced through the SYNC DETECTION WITH SSB feature – is the reason I chose this model. Was it a wise purchase? I’ll field test it in Part II to answer those questions.
Part II: Field Testing
Field Test Conditions:
Power: Battery, with no external antenna (only the internal ferrite bar antenna) though I did try enhancement through inductive coupling via a Terk Advantage and a Tecsun AN-200 – two very similar AM Loop antennas.
Audio:
I measured the speaker to be 3 ¼” in diameter. Too bad the analog slide tuning dial takes up 60% of the front of the radio because the cabinet size could support much larger speakers (“speakers” plural instead of singular) to produce much better sound. With AM DXing, I’m not interested in high fidelity. However, I found the audio to be good enough to fill the room with a pleasing sound.
There is a TONE switch. I suspect this is really a bandwidth setting as the translated owner’s manual states to leave it on “High” unless there is adjacent station interference (then toggle the switch to “Low”). To me the switch appears to be a wide(r) versus narrow(er) bandwidth – wider for fuller sound and narrower to help eliminate adjacent channel interference. It seems to function as intended.
FM:
The EX5MK2 is not renowned as an FM receiver. However, I was pleasantly surprised. It very easily pulled-in my favorite station about 40-45 miles away. During bandscanning across the dial, the receiver proved itself a decent if not worthy FM radio – not a DX machine, but of a quality where I wouldn’t feel I needed to reach for another receiver that possesses high fidelity audio. For general usage, I was pleased.
AM:
To me, AM performance is the meat and potatoes … AM is the reason this receiver is so popular with a huge following. Unfortunately, mine did not measure up.
To reiterate, I’m not a reviewer. I am not loaned complimentary radios to review. And as a retiree, I am not able to buy multiple samples. I can only evaluate the sample I received and thus I can only assume I have received a representative sample.
I quickly discovered the Sony EX5MK2 is the most RFI sensitive receiver I have ever encountered!
My Listening Post is a sitting room off the 2nd floor master bedroom. It extends outward from the main profile of my house with our breakfast nook underneath. This room has served me well for shortwave listening and AM DXing (AM DXing via several of my shortwave receivers).
However, the EX5MK2 proved to be quite fickle in this location. I was never able to completely eliminate the RFI issue I encountered with this radio. Even a FitBit in its charger created RFI so bad that the only thing heard between booming AM stations was a high-pitched RFI squeal. And this charger is plugged-in for perpetuity and has never cause any hint of an issue with any other radio (while sitting at my Listening Post, I routinely recharge my FitBit while listening to my radios – plural – and until now I had never, ever encountered any such RFI issue with my FitBit on any of my other SW radios). Frankly, I was dumbfounded to discover this.
I can only speak for my sample, but prospective buyers should keep RFI sensitivity in mind. Since I have never read any other report of RFI problems, maybe my unit is not properly shielded? Since I’m not a technically savvy “radiohead”, opening up the receiver to look inside would do me no good to evaluate its shielding.
Sensitivity:
I can see why people like the EX5MK2’s sensitivity (or the ability to receive distant AM broadcasts). During its first daytime test, I immediately and easily captured a signal from WWJZ 640AM in Mount Holly, NJ (Metro Philly). That station is approximately 300-miles to my northeast. It operates at 50,000 watts, however it’s not the easiest 50,000 watt station to receive from my location.
But complications from RFI interfered with my Field Testing.
After reasonably eliminating nearby RFI to include unplugging my FitBit, AM bandscanning revealed a horrible RFI hum (more like a shout and not a hum) – the worst of which is below approximately 850 kHz. It seemed the only stations that I was able to receive within this RFI Zone was the WWJZ 50,000 watt station and a couple of local stations. The true “DX Test” type of stations seemed to be buried in the RFI with zero chance of anything being audible. This was quite disappointing to say the least.
I continued with daytime as well as nighttime bandscanning over multiple days, however I found myself frustrated with interference issues. Yes, I easily received WSB AM750 in Atlanta at night (565 miles to my southwest), but again it seemed only the big boomers were receivable below 850 kHz and even some of the more local stations disappeared.
Comparing the EX5MK2 to my Yacht Boy 400 … yes, the YB400 received the same stations the EX5MK2 did, but the EX5MK2 definitely received them louder and more clearly (possibly attributed to the superior SYNC DETECTION of the EX5MK2). But most importantly to me the same interference issues that the EX5MK2 displayed did not plague the YB400.
I must admit, at this point frustration & disappointment out-weighed my planned Field Testing and I lost my desire to continue with rigorous testing.
Some people reading this might be disappointed and may be thinking, “why didn’t you take this outside, or into the countryside away from possible RFI sources?” to finish the testing. That’s not how I use my radios. Nearly all of my listening is from my house. Yes, I may have been able to isolate and better diagnose the interference problems I encountered by going outside my house. But I had already made the decision that this radio was going back to Amazon. In the end, my 1994 Yacht Boy 400 better met my needs than the EX5MK2.
Note:
The SYNC DETECTION feature on the EX5MK2 appeared to justify its hype. Unfortunately due to my RFI issue, I never truly put the USB/LSB feature to a test. Yes, isolating the USB/LSB did help to separate several distant stations on the upper two-thirds of the AM band, but in my opinion a true SELECTIVITY test would be to separate and receive a distant, weak station from the adjacent channel interference of a much stronger station. I never encountered this opportunity, but I must also admit that I essentially abandoned the Field Testing once I decided to return my EX5MK2.
Also, and I don’t know why, inductive coupling with a Tecsun AN-200 enhanced the EX5MK2’s AM reception but the Terk Advantage didn’t yield the same results. They are similar antennas and why the AN-200 was exponentially superior to the Terk Advantage is not something I can answer.
Summary:
Given its reputation, I am sure the EX5MK2 is a good, if not great, receiver. But my sample, for whatever reason, did not measure up.
And please, if you soon see an “open box” EX5MK2 listed on Amazon – it quite possibly will be the one I returned! My recommendation is to pass on that one and purchase a new, sealed box unit.
Many thanks, Troy, for sharing your detailed review/report of the Sony EX5MK2. Thank you, especially, for taking the time to translate the EX5MK2 manual.
As Troy mentions, perhaps he simply received a lemon unit–one that had quality control issues such as possible shielding and/or grounding problems.
I can tell you as a reviewer that there are few things as frustrating as throwing yourself into a highly-anticipated review only to be disappointed by your particular unit’s performance. It’s like buying a new car only to find out it rattles as you drive–!
I am very curious if anyone else has purchased the EX5MK2 from Amazon recently and experienced similar issues? Or, have you found that this analog receiver lives up to its stellar reputation? Please comment!
