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 reader, Larry Thompson, who shares his review of the CountyComm GP5/SSB:
Been having a ton of fun with my new toy, the tiny survivalist radio, the CountyComm GP5/SSB receiver. $74.95 with free heavy duty cordura case with metal belt clip (normally $17.95). Also purchased 2 spare whip antennas @ $6.00 ea. The unit arrived promptly
in just 5 days from CA.
The radio is manufactured by Tecsun and is similar to the Tecsun PL-365, but re-engineer end to military standards for use in embassies and military installations around the world. The case is a heavy plastic that feels like anodized aluminum.
It’s about the size of a small TV remote control, taller than a cell phone, and about 1/2 the width of an iPhone.
Very, east intuitive menus. Incredibly sensitive to dx, relatively good selectivity. A great radio to throw in your travel bag or briefcase. So small that no one, especially customs, TSA, etc would even suspect it is a shortwave receiver with SSB capabilities.
I live in a very highly QRM and RFI interference zone.
I’m in the central city, in an old 1920’s hi-rise, with high power tension lines right next to the building.
Lots of QRM from the elevator motors, etc. Having a good antenna option is a challenge.
I’ve resorted to a stealth longwire antenna, strung out my 5th floor window. It’s 50′ of #16 black insulated copper stranded wire, weighted by a medium size galvanized carriage nut. It seems to work well.
I also use a Magic Wand shortwave antenna, a type of broomstick antenna with 23′ of lead-in, available from Lowbander on eBay.
My main receivers have been a Sony ICF-SW7600GR dual conversion receiver and the SRDPlay. In the past, I have listened to dx with some really outstanding receivers, including a Nordmende Globetrotter, a National NC-183D, a Japan Radio JRC-525′ and a Yaesu FT900AT transceiver. The later two were computer-controlled using TRX-Manager software.
In just 4 days, I can’t get over the sensitivity of the CountyComm GP-5/SSB and it’s ability to pull in stations. So far, it’s far superior to the Sony or SDRPlay.
Digging into the specs, it is a direct conversion receiver, using a DSP si47XX microchip from Silicon Labs to digitize the analog AM/FM broadcasting signal base on modern software technology and radio principles. The direct conversion circuitry can highly improve a radio’s sensitivity, selectivity, S/N ratio and anti-interference capabilities. Direct conversion using software is far superior to a double or triple conversion traditional IF circuitry. This must explain why the unit is so amazingly sensitive!
I can hear things on this unit that I can’t even begin to hear on the Sony or the SDRPlay. The FM reception and sound with earphones is amazing and LW and AM reception is equally sensitive. I can easily get WLW Cincinnati 700 kHz in the daytime here in St. Louis!
There are 550 preset memories: 100 for AM, 100 for FM, 100 for SSB, and 250 for SW. You can scan the memories or scan the bands in various ways. You can also use the Auto Tune Storage function to store memories.
Something I really enjoy is the Easy Tuning Mode function. The ETM function allows you to tune into stations easily and temporarily store them into the ETM storage. 100 stations for FM/MW and 250 for SW. Scanned stations will not be stored in the regular 550 memories, but will remain in the ETM temporary storage until the next time you do an ETM scan.
This is a great feature for travel. When you are in a different city, you can perform the ETS function and this will not delete any of the stations already in the memory.
Thanks for sharing your review, Larry. I use the GP5/SSB all of the time–it stays in one of my vehicles and I often use it for walks, picnics, camping and even a little parking lot DXing.
I suspect if your SDRplay RSP was hooked up to an antenna that could better mitigate your local QRM, you’d find it outperforms the GP5/SSB. The great thing about portables, though, is that you can simply take them to areas with low noise levels. It’s just a matter of finding the right location!
The CountyComm GP5/SSB is a very handy portable. Thanks again!
The CountyComm GP5/SSB can be purchased from:
CountyComm (current promo includes heavy duty carry case)
The Tecsun version, the PL-365, can be purchased on eBay (though be aware that some sellers have BuyItNow prices almost two times the price of CountyComm).
As you can see in the image above, this antenna is substantially larger than the stock MW antenna supplied by the manufacturer. According to the seller, this ferrite bar antenna has a 10 – 25 db gain over the stock external antenna. I imagine its ability to null unwanted signals is also much better.
On Tuesday I received the new CountyComm GP5/SSB portable shortwave radio, a sample sent me from CountyComm. If you’re familiar with the current shortwave portable landscape, then you’ll quickly note that the GP5/SSB shares a striking resemblance to both the GP5/DSP and the Tecsun PL-360. While I hadn’t anticipated writing yet another radio article before the end of the year, having just published a lengthy review of the CC Skywave, my curiosity got the best of me…and before I knew it, I’d spent a few hours listening to and making notes about the CountyComm GP5/SSB as I put it through its paces. In the end, I found I had the makings of a review.
Who is CountyComm?
Unlike most other brands I review, CountyComm has only one or two shortwave radio offerings. I wanted to know a little of the back story and motivation behind creating the GP5/SSB, so I contacted CountyComm directly and spoke with their representative, Nick.
Nick explained that CountyComm is a retail distributor of products created primarily for US government use. In a sense, CountyComm is the consumer spill-over from the thousands of products intended, for example, for state and federal agencies.
According to CountyComm, the GP5/SSB is a case in point. The company received a large order from a US government department for an “inexpensive, small portable, AM/FM/SW radio with SSB” for emergency supply caches and diplomatic posts. The GP5/DSP (a.k.a., Tecsun PL-360) fit the bill, but lacked SSB. The request was large enough that CountyComm approached SiLabs–manufacturer of the DSP chip in many of the portables on the market–and asked for help. SiLabs made some design changes and worked directly with the factory in China to produce the GP5/SSB.
The GP5/SSB comes with a medium wave bar antenna, carry pouch, stereo ear buds, wire antenna and manual.
Besides SSB, another interesting design CountyComm implemented was extending the upper frequency range of the GP5/SSB to 29,999 kHz; previous and similar Tecsun models only had an upper limit of 21,950 kHz.
You may note that as of today, there are no similar Tecsun portables on the market–this is because the first batch of units were designed for (and all purchased by) CountyComm. However, I have already heard rumblings that there will soon be a Tecsun PL-365 on the market–if so, no doubt it will turn out to be the GP5/SSB.
First impressions
Appearance-wise, the GP5/SSB is nearly identical to its predecessor, the GP5/DSP or Tecsun PL-360. The vertical form factor is rather unique in the ultra-portable world, this radio is designed for one-handed operation, much like a handy-talky. The volume and tuning controls are on the right side of the radio and are designed to be operated by thumb (for right-handed operators, at any rate). All of the buttons on the front face are easily operated by your thumb–they’re small, but have a firm response. The GP5/DSP (like its predecessor) lacks a back stand, but does have a belt clip.
The small internal speaker produces clear audio, but sounds a little tinny; there is not even a hint of bass. Via headphones, the audio quality is far better.
Besides a slight modification to the keypad layout to accommodate the new addition of SSB and a bright green antenna tip, the radio is identical to the GP5/DSP and Tecsun PL-360.
FM Performance
The CountyComm GP5/SSB, like many other SiLabs-based receivers we review, has excellent FM sensitivity.
Medium Wave (AM broadcast band) Performance
The MW bar antenna increases performance–if using headphones, you will need a right angle connector to allow the MW antenna to rotate 360 degrees
While I have not yet had the opportunity to do a proper comp recording session with the CountyComm GP5/SSB versus comparable radios, I plan to do so in the near future…stay tuned for that, right here! I’ll create a post to give you a heads-up when I’ve added medium wave samples to this review.
With that said, I expect the GP5/SSB performance on medium wave will be very similar to that of the GP5/DSP and Tecsun PL-360. I like the included rotatable ferrite bar antenna that plugs into an external antenna port on top of the radio. It certainly helps with both overall sensitivity as well as nullifying unwanted signals.
Shortwave performance
I’ve had a couple of opportunities to compare the GP5/SSB with other portables on the shortwave bands; embedded audio samples follow of a strong station, a weaker station, and even an SSB sample. Note that all of the sample recordings were taken during poor band conditions–QSB (fading) is pronounced.
Single-sideband
Of course, when I received the GP5/SSB, the first thing I did was tune the ham radio bands in SSB mode.
Nick, the CountyComm rep in charge of the GP5/SSB design, is an amateur radio operator, and I’m pleased that he represented the importance of a truly functional SSB mode on this radio.
The GP5/DSP only has 1 kHz tuning steps: more than adequate for broadcast listening, but too coarse for SSB. Amateur radio operators do not necessarily transmit right on a frequency; they’re often slightly off-frequency, either accidentally or intentionally. And older ham radios are also prone to drifting until the rigs have properly warmed up. Radios with SSB need finer-tuning controls to hone in on SSB signals. But the GP5/SSB has a work-around for this.
The GP5/SSB accommodates SSB by allowing the listener to select either the upper or lower sideband, then use the BFO function to help fine tune and zero-beat a signal.
Specifically, here’s how to tune to an SSB (phone) amateur radio signal with the GP5/SSB:
Turn on either the upper or lower sideband, depending on the meter band (generally, 40 meters and below are lower; all else, upper).
When you hear a signal, use the 1 kHz tuning increments to find where it’s strongest.
Now, press the BFO button once to activate BFO tuning; the U or L (indicating upper or lower) will begin to blink.
While the sideband indicator is blinking, use the tuning wheel to adjust the BFO. Adjust tuning until the voices in the signal sound natural.
Once you’ve done this a couple of times, the process becomes second nature.
Overall, I’m very pleased with the SSB functionality and performance. While I prefer either very fine tuning increments, or a separate BFO knob (no room for that on this tiny radio), I appreciate that CountyComm has used the BFO function to eliminate the need for a separate tuning wheel.
Audio samples
While there are a number of portable radios with SSB on the market, there are very few in this $80 price range with SSB. Indeed, to my knowledge there are no other SSB-capable portables currently on the market that are as compact as the CountyComm GP5/SSB.
Below, you can hear two representative audio samples of how each radio receives an SSB conversation between two ham radio operators on the 20 meter band. I like this sample because one of the operators has a very strong signal, while the other is much weaker:
You may notice that the GP5/SSB has a slightly higher noise floor and DSP artifacts while listening to the weaker signal. The PL-600 sounds a little muffled in comparison.
I listened to many SSB signals that afternoon on the 20 and 40 meter ham radio bands. At length I concluded that I prefer the PL-600 for weak-signal listening. The PL-600’s AGC could cope with the QSB better than the GP5/SSB.
With the majority of the SSB signals, however, I found that the GP5/SSB’s audio was clearer and voices seemed to “pop” out better than on the PL-600.
I should note that I also attempted to include the Grundig G6 in this comparison, but the G6 somehow picked up noise from my digital recorder, thus making the recorded audio sound worse than it actually was. To my ear, the Grundig G6’s SSB reception was very similar to that of the CountyComm GP5/SSB–the G6 perhaps has a veryslight edge in terms of weak-signal reception.
This morning I also had an opportunity to record Radio Australia on 12,065 kHz. This time, I had the Tecsun PL-310ET handy, so I used it for comparison:
As you probably hear in these examples, the GP5/SSB has fine sensitivity, though not quite as good as the PL-310ET.
I’ve also noted good selectivity during casual broadcast listening with the GP5/SSB.
However, I do not like the GP5/SSB’s AGC (auto gain control) as well as that of the other portables in this comparison–it’s a little too reactive to fading on the broadcast bands. To be fair, these audio samples really accentuated the AGC on the GP5/SSB since all were made during poor reception conditions and pronounced fading.
Under normal conditions, I believe I would be quite pleased with the GP5/SSB; it’s otherwise on par with most of the other ultra-portables on the market.
Summary
Every radio has pros and cons, and I jot down my reactions as I evaluate a new radio so as not to forget any details. The following is my list:
Pros:
Audio well-tailored for AM broadcast listening–fidelity quite good via headphones
Adequate sensitivity and selectivity
Clear, simple LCD back-lit display
SSB mode is quite functional
BFO feature allows for zero-beat tuning
Includes both upper and lower sideband selection
Much like the PL-880, when in SSB mode, the GP5/SSB will select ham bands when changing meter bands
Extended frequency range (up to 29,999 kHz)
Very good medium wave reception with supplied external bar antenna
Uses three standard AA batteries
Can be charged with common mini USB adapter
Displays temperature in Fahrenheit (if MW set to 10kHz steps) or Celcius (if set to 9 kHz steps)
Great radio for an emergency kit or bug-out bag
Designed for one-hand operation/included belt clip (see con)
US Warranty
Cons:
AGC doesn’t cope with fading as well as other comparable portables
Audio from internal speaker rather tinny (without headphones)
No back stand, nor rotatable whip antenna; thus this radio is not ideal for tabletop listening (see pro)
If you’re looking for an ultra-portable radio for travel and general broadcast listening, I would encourage you to consider the new C. Crane CC Skywave, the Tecsun PL-310ET or the Tecsun PL-380. Overall, the performance and form factor of these radios are a better fit for broadcast listening. If you’re looking for armchair SSB listening, a larger portable with a larger internal speaker such as the Tecsun PL-600 is a good choice for the same price as the GP5/SSB.
If you’re looking for an ultra-portable radio with SSB, then the GP5/SSB is a very good choice (if not the only ultra-portable SSB choice currently on the market). While the SSB performance can’t compare with larger, pricier receivers and ham radio transceivers, it’s very good for $80 US.
If you’re looking for an emergency communications receiver–something to stash in your vehicle, emergency kit or bug-out bag–the CountyComm GP5/SSB is a great choice and value. Indeed, that’s who the GP5/SSB was designed for; that’s why this rig has excellent frequency coverage in all modes, with good sensitivity/selectivity and designed for portable, one-hand operation. In fact, CountyComm has even designed and manufactured (in the USA!) a robust, protective 1000-Denier case for the GP5/SSB. This case makes it very easy to strap the GP5/SSB to your belt or backpack securely.
In conclusion, the CountyComm GP5/SSB was designed for a specific purpose: to be an emergency communications receiver. It does this job quite well, despite any shortcomings in comparison to other popular shortwave portables, and for this purpose, I can recommend it.
