Guest Post: Richard tests the frequency stability of the Tecsun PL-880

PL-880 (1)Many thanks to SWLing Post contributor, Richard Langley, for the following guest post:


Frequency Stability of My Tecsun PL-880

Recently, while recording the audio on a particular SW frequency unattended over night, I decided to set my Tecsun PL-880 in USB mode with the 3.5 kHz RF bandwidth setting as I had previously noticed splatter QRM from a station 10 kHz below my frequency of interest. I adjusted the frequency to the nearest 10 Hz for natural-sounding voice. On playing the recording, I was disappointed to find that the signal had drifted in frequency and although speech was still recognizable, music was distorted.

I decided to try to measure the stability of the receiver by recording the Canadian time signal station CHU on 7850.00 kHz in USB mode (CHU has no LSB component) over night for over nine hours. The receiver was operated with just its telescopic whip antenna indoors and the audio was recorded with a Tecsun ICR-100 radio recorder / digital audio player. I wrote a Python script to compute the audio spectrum of each one-minute segment of the recorded files using a fast Fourier transform (after removing a DC component). The script then looks for the largest peaks in the spectra centred on a specified frequency and prints out the frequency (to the nearest Hz) and amplitude of the peak. In case the signal has dropped below audibility, a threshold is set and if the detected peak is below the threshold (likely just detecting the random noise background), it is skipped. The specific centre frequency I was looking for was 1000 Hz, the frequency of the tone used to mark each second of the CHU broadcast except when the voice announcement and digital signal are transmitted. In AM mode, the spectrum would consistently show a peak at 1000 Hz but in SSB mode, the peak will vary depending on the receiver frequency setting and the actual frequency of the receiver’s oscillator.

The plot below shows the received CHU one-second tone frequency as a function of time (UTC) from when the receiver was first switched on.

StabilityPlot-CHU1000hz

It shows the tone frequency started out at about 1046 Hz slowly dropping in the first half hour to about 1012 Hz and after about an hour stabilized to 1011 Hz ± 1 Hz for the better part of an hour. (This shows that you may have to allow a receiver to “warm up” for perhaps up to an hour before attempting anything close to accurate frequency reading at the order of 10 Hz.) But then, over the course of the next seven hours when the signal was audible, the frequency slowly rose ending up at about 1034 Hz. The variation might be affected by the ambient air temperature (but this should have been nearly constant), air flow around the receiver, and perhaps the charge level of the receiver’s battery. On several occasions, I have turned the receiver on (after being off for many hours) and seen a CHU frequency offset of only 10 or 20 Hz. So, I intend to repeat this experiment sometime to check on the day-to-day frequency stability. This frequency stability measurement technique could also be used with WWV/WWVH by recording the 440, 500, or 600 Hz tones broadcast at different times during the broadcast hour.

Of course, it’s also possible to check the receiver’s frequency offset in real time by switching between AM and SSB modes while adjusting the receiver frequency in 10 Hz steps until the signal sounds the same in both modes. There is also freely available computer software for various operating systems that can display a real-time spectrum of audio passed to it through a microphone or line input. So, a CHU or WWV/WWVH test using such software could also be performed in real time. And alternatively, by tuning say exactly 1 kHz away from the transmitted carrier frequency in SSB mode, the software can be used to measure the audible heterodyne frequency to better than 10 Hz — even 1 Hz. This frequency can then be added or subtracted as appropriate to the dial reading (assumed accurate or with a noted offset) to get the exact transmitted carrier frequency.

By the way, it is possible to calibrate and reset the PL-880 using the procedure documented on the SWLing Post (click here to view).

As a side benefit of the analysis I carried out, we can also look at the quality of the received signal over the recorded interval. In this case, it is a measure of the level of a particular audio frequency rather than the RF signal+noise level we usually get from the receiver S-meter or other signal strength display. This is illustrated in the plot below for the CHU recording. As you can see, reception was mostly quite good between about 02:00 and 04:00 UTC and then became fair but above threshold level until about 05:30 UTC.

AudioLevel-CHU7850kHz

The signal was then essentially inaudible up to about 08:00 UTC when with bouts of fading it became audible again for an hour or two with sunrise approaching.

Richard’s search to find the best SWLing spot on campus

Richard-UNB

SWLing Post contributor, Richard Langley, has been seeking the perfect spot on the campus of the University of New Brunswick (UNB) to listen to shortwave. He recently shared the following:

Here’s a link to a brief video of my recording of last weekend’s VOA Radiogram “in the field” (a UNB parking lot):

Richard goes on to say that he’s found an even better location:

receiver_locations_smaller (1)

“That location on campus (green pin on attached image) turned out to not be noise-free on all bands. Found an even better location (red pin). Negligible power-line interference although still within Wi-Fi range of UNB’s system but no significant effects from that discovered yet. Got excellent reception of VOA’s Radiogram this past Saturday afternoon. Extremely clean waterfall in Fldigi. And virtually noise-free images [below]”

Many thanks for sharing this with us, Richard!

Those of you who live or work in areas with significant radio noise should consider scouting out a listening spot like Richard has. Also, you might be inspired by LondonShortwave who takes his radios to public parks. Regardless, moving your receiver as far away from sources of radio interference as possible will always yield better listening results.

Do late model PL-880s lack some hidden features?

Tecsun-PL-880-Manufacturing-date-SWLing-Post

SWLing Post reader, Del Fields, writes:

“I’ve bought a new PL-880 this year (2015) and apparently some of the “hidden features” are not hidden anymore. They don’t even exist. HaHa.

For example, I tried the DNR hidden function by pressing and holding 6. Nothing.

Also I tried the hidden date of manufacture trick…..nothing. I tried the pressing holding while turned off, the AM BW button and did that twice and got “8820”. Pressing and holding a third time just returned it to normal off screen. Just fyi. But I do wish there was a DNR function or a squelch feature.”

This is interesting, Del–I have no late model PL-880s to try out these hidden features. My PL-880 dates from November 2013 (see the manufacturing date displayed on screen above).

Have any others who have recently purchased the PL-880 noticed this? Click here for a complete list of PL-880 hidden features.

Pete gives Kaito high marks for customer service

PL-880 (1)

SWLing Post reader, Pete Jernakoff (K3KMS), writes:

“I purchased two PL-880 radios from Amazon about a year ago and before the soft muting issue became a hot topic. Both of my radios (8819 firmware version) suffered from this most annoying problem but it wasn’t until I started reading your excellent blog that I learned of the cause.

About two weeks ago, I called Kaito Electronics USA and asked if they could upgrade the firmware on my two radios to the 8820 version. The person I spoke to said (paraphrasing) “Sure! Send them to us any we’ll perform the upgrade for free. All you do is pay for the return shipping.”

So off the radios went to Kaito. About 10 days later I had them back with the new firmware installed. The return shipping was $10. Weak MW and SW signals are now easy to listen to: no soft muting issues at all. Kudos to Kaito for agreeing to perform the upgrade for me. My dealings with them were thoroughly pleasurable.”

Thanks for sharing that great experience, Pete! You’re right–the 8820 upgrade is certainly worth the shipping costs and I’m happy to hear Kaito makes the process so easy.

Charging the Tecsun PL-880 with the C. Crane Witness AC Adapter

CCWitnessAdapterSWLing Post reader, John Case, comments:

“I bought a C. Crane Witness AC Adapter to try it out on the PL-880. It is rated at 900 mA, more than enough to handle the PL-880. I think it is more than reasonable at $14.95.

I am happy to say that it works very well on the PL-880 and does not introduce any noise in any mode , even when the PL-880 is recharging the internal Battery. I also ran the PL-880 in Shortwave without the battery with no problems off of this AC Adapter. All in all, it is very well filtered, and thus quiet.  I can highly recommend it for use with the PL-880.”

Update–John adds:

“I should add that the idea to use the C. Crane Witness AC Adapter for the Tecsun PL-880 came from Dave Zantow, of “Dave’s radio Receiver Page”. He had looked at the Skywave adapter, but it is rated at a maximum of 300 mA, while the PL-880 is rated at > 300 mA. Dave originally tested the Witness Adapter on the Degen DE 1128H, and was pleased with the results. Unfortunately he no longer had his PL-880 test sample, so he could not test the adapter with that radio.

He did add one cautionary note that it may be necessary to add bypass caps to the power regulators to avoid picking up low level switching hum on a whip or other indoor antenna. I did not experience any of this, but it sound like a good idea easily implemented. Dave’s review is at the bottom of this page: http://webpages.charter.net/n9ewo2/ats909x.html

Many thanks, John! I may pick up one of these myself–would be nice to have a regulated supply for many of my radios and digital devices. (Would come in handy if I ever decide to pull the trigger on the CC Witness, too!)

The SWLing Post 2014-2015 Shortwave Radio Buyer’s Guide

RadiosShootOut-SonyTecsunSangean

The following article originally appeared in the November 2014 issue of The Spectrum Monitor magazine.


Although many large government shortwave broadcasters are departing the shortwave radio scene, there’s no shortage of great products being introduced to it. Indeed, growth in the portable and SDR (software defined radio) markets is reasonably rapid.  This suggests, perhaps, a new kind of future for shortwave.

The following is a basic, easy-to-follow buyer’s guide to some of the best receivers on the market. This guide is, by no means, comprehensive; rather it’s a selection of rigs I know or own, thus have tested.

Compact/Travel portables

If your budget is tight, or if you’re looking for a radio that could easily slip into your glove compartment, backpack, carry-on, or even jacket pocket, you need to look at an compact shortwave radio. Typically, there is a performance compromise with compact radios: they don’t typically have the sensitivity, like their more expensive cousins; they have a more limited frequency range; and they don’t detect single-sideband signals. Nonetheless, the ones listed here are fine performers for their size and price. Entries are listed in alphabetical order.

ccradio-swpCrane CCRadio-SWP

The CC Radio SWP has been on the market for many years and has become a classic portable. The layout and design are very simple, the display clear, with easily-read icons and intuitive controls. The tuning knob on the right side is for fine tuning–no muting or chugging between frequencies, either. Shortwave and MW sensitivity are better than one might expect for a radio this size; I often find myself comparing it to much pricier portables. But most significantly, this radio offers the longest battery life of any radio I own: almost 70 hours on 2 AA cells!

The CC Radio SWP is available from C.Crane for $55.00 US. You can also purchase the CC Radio SWP from Universal Radio ($44.95) and Amazon.com.

Note: The CC Radio SWP may soon be replaced by the new CC Skywave which has just started shipping at time of posting.

KA1103Kaito KA1103 or Degen DE1103

The Kaito KA1103 packs a lot of bang-for-your-buck if you’re looking for an inexpensive, ultra-portable entry into SWLing. Like the CC Radio SWP, the KA1103 (a.k.a. Degen DE1103) has enjoyed a long market life. The KA1103 is full-featured and one of the only sub-$100 radios with SSB mode. One interesting design feature of the KA1103 is its large Digital/Analog frequency display: the LCD screen features the frequency display in digits, but also sports a working digital representation of an analog frequency dial. As you tune up and down the band–with, yes, a tuning knob–the LCD needle moves along the display as it would on an analog radio dial. While I believe radio ergonomics could be improved, the KA1103 is still a great bargain.

The KA1103 is available at Universal Radio for $79.98 and Amazon.com for $79.99. Click here to search eBay for the Degen DE1103.

Tecsun PL-310ETTecsun PL-310ET

The Tecsun PL-310ET is an updated version of the acclaimed PL-310, a mini-legend in the world of portable radio, offering exceptional value and high-performance in a small package. The PL-310ET is fueled by a SiLabs DSP (Digital Signal Processing) chip that gives this ultra-portable excellent sensitivity and selectivity. The PL-310 has been a favorite amongst ultra-light Dxers, as sensitivity and selectivity are  exceptional for the price. The new “ET” version of the PL-310 sports ETM tuning; a feature which allows you to scan the entire band and automatically store all strong stations to temporary memory locations. I believe the updated PL-310ET also has better AGC for weak signal DXing than its predecessor. Another bonus is that the PL-310ET sports an external antenna jack for shortwave and FM reception.

The Tecsun PL-310ET is largely available from Hong Kong-based sellers on eBay (http://ebay.to/1seZP3h) as well as on Amazon.com.

Tecsun-PL-380Tecsun PL-380

The Tecsun PL-380 is my favorite radio under $60. Much like its cousin, the PL-310ET (above), the PL-380 has a DSP (Digital Signal Processing) chip that gives this ultra-portable excellent sensitivity and selectivity. For three years, I have traveled extensively with the PL-380 in tow, and I’m constantly amazed by this radio’s excellent audio and reception across the bands.

The Tecsun PL-380 is available from Universal Radio for $59.95 and from Amazon.com for $54.99. Click here to search eBay for the PL-380.

Tecsun offers a number of compact portables, based on a similar DSP chip as the PL-380, but with built-in stereo speakers. Check out the Tecsun PL-390, PL-398BT, and PL-398MP, too.

Full-Featured Portables

In the portables market, I believe you get the most value and quality in the $90-250 price class. Most beginners and seasoned SWLs prefer a radio that includes everything necessary to get on the air immediately; all of these radios provide just that. Straight out of the box, you’ll have everything you need to listen to shortwave bands. All of these recommended radios are designed to pick up major shortwave broadcasters with ease, and offer the following features: good frequency coverage; circuitry that helps in the detection of weaker stations; and the ability to receive single-sideband (with the exception of the CCRadio-SW, see below).

ccradio-swCrane CCRadio-SW

If you’re not as concerned about portability, the C.Crane CCRadio-SW is an excellent broadcast receiver. Think of the CCRadio-SW as a larger portable or tabletop radio (11.25″ x 7.25″ x 3.5″). What makes this radio stand out from its peers? Exceptional audio fidelity. The large built-in speaker has separate treble and bass controls and reminds me how important audio quality is while listening to a faint signal. This radio’s audio will fill a large room. Shortwave sensitivity is very good. Medium wave (AM broadcast) reception is excellent. Negatives? No direct keypad for frequency entry, and the SW also lacks a native SSB mode (a rare missing feature in this price class). With that said, it does have impressive array of external connections, including an IF-Out connection, which (with an IF converter and some free software) will allow you to interpret SSB and an array of digital signals, including DRM (Digital Radio Mondiale). What really strikes me about the CCRadio-SW is its sheer ease of use.  Its design is simple, ergonomic, and highly effective. I’ve often recommended the CCRadio-SW to listeners who want simplicity of use and robust audio.

The CCRadio-SW is available for $149.95 at C.Cranes’ website, $129.95 from Universal Radio and is also available on Amazon.com. Click here to check eBay for used models.

Radios with a similar form-factor include the Grundig S450DLX and the new Eton Field.

ATS-909XSangean ATS-909X

At $249.95, the Sangean ATS-909X is one of the priciest full-featured portables on the market. The 909X sports a large alpha-numeric display, tactile buttons, and a solid build quality. I also believe the 909X has a one of the better internal speakers and audio fidelity amongst portables. Negatives? Surprisingly, the 909X lacks synchronous detection, a tool most other portables have in this price range. Additionally, in my recent shortwave portable shoot-out, I gave the Sangean low marks for sensitivity; this review was based upon use of the built-in telescopic antenna. With an external antenna, on the other hand, the 909X performs admirably. If you’re looking for a quality portable with a front-end robust enough to be attached to a larger external antenna, the 909X may very well be your radio.

The Sangean ATS-909X is available at Universal Radio for $249.95 and Amazon.com for $219.99. Click here to search for used ATS-909Xs on eBay.

Sangean still has several models of portables available.  Check out the Sangean ATS-404 and ATS-505P.

Sony7600GRSony ICF-SW7600GR

For performance, you’ll find that the Sony ICF-SW7600GR is top of its class among full-featured portables. Two of its outstanding features is a solid synchronous selectable sideband (a feature which helps to reduce fading distortion and adjacent-channel interference) and stable AGC circuit. In fact, the ICF-7600GR was chosen as a favorite in a blind audio test on the SWLing Post. Indeed, my only criticism of the ‘7600GR is that it lacks a tuning wheel; instead, you’re forced to use tuning buttons on the front face of the radio.

The Sony ICF-SW7600GR is available at Universal Radio for about $150.00 and at Amazon.com for $130-150.00. Click here to search eBay for a used ICF-SW7600GR.

KX3-Helper-Tecsun-PL-600Tecsun PL-600

The Tecsun PL-600 is the value leader among the full-featured portables in this list. It can be found at a wide array of retailers, such as Universal Radio, Amazon and eBay. Price ranges from about $65 to $90. I’ve often recommended the PL-600 as a first full-featured radio for the budding SWL, and for good reason: the PL-600 has great sensitivity, selectivity, and even has capable single-sideband reception. The PL-600 does a surprisingly good job of holding its own against the other contenders in this list. Negatives? Like all sub-$100 portables, the PL-600 lacks synchronous detection (and if this is a deal-killer for you, check out the PL-660). Additionally, the PL-600 is not well suited for large external antennas; but it does work quite well with its own antenna. In a nutshell: if you’re not willing to spend over the $100 mark, the PL-600 is a safe bet.

The Tecsun PL-600 is available at Universal Radio for $89.95. Click here to search eBay for new and used PL-600s.

PL-660Tecsun PL-660

The Tecsun PL-660 is one of the best selling portable shortwave radios currently on the market–and for good reason. This rig has a full compliment of features and is quite easy to operate. The sync detector (selectable USB/LSB) is currently one of the best in the sub $150 US price range. Sensitivity and selectivity are both excellent; indeed, I consider it to have the most sensitive receiver among the portables listed here (and so. With the introduction of the Tecsun PL-880 on the market, the PL-660 has also become more affordable and can be found at or near the $100-120 price point with shipping. What a bargain!

The Tecsun PL-660 is available at Universal Radio for $109.95 and on Amazon.com (prices vary). Click here to search fro a new or used PL-660 on eBay.

Tecsun PL-880PL-880 (1)

The Tecsun PL-880 was introduced to the market one year ago (November 2013), and while the introduction was a bit bumpy (feature variation based on differing firmware versions), it has recovered and found quite a good following. While the PL-880 does not rank as highly as the PL-660 or ICF-SW7600GR in terms of sensitivity (see review TSM June 2013) it does have compensating factors.  For one thing, the PL-880 has the best audio fidelity from its internal speaker among the radios listed here. It’s also the most feature rich, boasting the most filter selections and a growing number of “hidden” features (http://wp.me/pn3uc-2tl). I also love the build quality, ergonomics, and tuning options; indeed, the PL-880 even has a dedicated fine tuning control. Negatives? Though the PL-880 has an undocumented sync detection among its “hidden” features, I find its sync lock quite feeble, compromising audio fidelity a bit too much. If you’re looking for a small portable that will fill a room with rich audio–whether you’re listening to the BBC, a classical concert, or just two ham radio operators chatting on 40 meters– look no further than the PL-880.

The Tecsun PL-880 is available at Universal Radio for $159.95 and on Amazon for $159.99. The Tecsun PL-880 is also available from Hong Kong-based sellers on eBay.

New Eton portables now shipping

Eton-SatellitAt time of publishing, Eton Corp–the North American distributor of Grundig–has four updated models of shortwave portables new to the market. All are updated versions of recently retired Grundig models:

If history is a guide, I expect all of these radios to prove worthy of the 2016 Shortwave Radio Buyer’s Guide. Indeed, preliminary reviews of the Field have been most favorable. Barring schedule changes, all models should be available in time for the 2014 holiday season…Stay tuned.

Tabletop receivers

While tabletop receivers have started to decline with the advent of SDRs, there are many listeners who still prefer a simple, dedicated, stand-alone high-performance receiver with a good tuning knob and clear display, which is to say, a tabletop receiver. Tabletops are designed to perform best with a resonant external antenna.

AlincoDXR8TFrontFaceAlinco DX-R8T

I reviewed the Alinco DX-R8T in 2011 a few months after it was introduced. I was favorably impressed with the DX-R8T. So much so, I purchased one after the review. It has excellent selectivity and sensitivity, a large display and tuning knob, a detachable faceplate (if your desktop space is limited), and a decent built-in speaker. What’s more, the DX-R8T has an SDR mode that allows you to hook up the receiver to your PC to see a spectrum display, and with an optional accessory cable, control its rig functions and tuning. The DX-R8T requires a regulated 12-volt power supply (not included). Cons? The DX-R8T lacks a selectable synchronous detector–a feature I enjoy using to combat adjacent signal interference.

The Alinco DX-R8T is available at Universal Radio for $449.95. Click here to search eBay for the Alinco DX-R8T.

Icom-R-75Icom R-75

Various versions of the Icom R75 have been on the market for well over a decade.  This receiver stands the test of time because it’s a full-featured tabletop with attributes like twin passband controls, a two-level pre amp, separate AF/RF gain, adjustable AGC, an alpha numeric display, a direct frequency entry keypad, not to mention a logical, ergonomic layout for all controls.  Amateur Radio operators, pirate radio listeners, as well as utility broadcast listeners will all appreciate the R75’s performance in SSB mode. Cons? The current base version of the R75 lacks synchronous detection, though some models in the past have had this option.

The Icom R75 is available at Universal Radio for $669.95. Click here to search eBay for the R75.

SDRs/IF Receivers

If you’re searching for maximum performance for the price, software-defined radios (SDRs) and IF receivers are hard to beat. These small “black box” radios require a computer to unlock their performance; none of these are stand-alone. But while I’ve never been a fan of combining my PC with radio listening, once I starting using an SDR, I never turned back.  Now, 90% of the time that I’m on the air, it’s with an SDR. They’re simply incredible.

The following selection of SDRs–and IF receivers–are all available for $1,000 or less.

BonitoRadioJetDaytonBonito RadioJet IF-Receiver 1102S

The Bonito RadioJet is included in this group because it is very similar to an SDR, but strictly speaking, it’s an IF receiver. Like an SDR, it requires a PC for operation. But while the RadioJet’s spectrum bandwidth is more limited than the SDRs that follow, it has advantages over the others.  For one, the RadioJet is more akin to a PC-controlled radio–most of the hard work is done in the receiver itself, not your computer–-so even older model Windows PCs, tablets and netbooks can run the  RadioJet application with ease. The RadioJet is great for travelers since it requires no external power supply: it derives its power from your computer, from the same USB cable used for data. The RadioJet is an excellent receiver and has a very low noise floor. If you like listening to DRM, you’ll be impressed with its native ability to decode the mode. Click here to read my comprehensive review of the RadioJet.

The Bonito RadioJet 1102S is available at Universal Radio for $649.95. The RadioJet can also be purchased directly from Bonito in Germany.

Elad-FDM-S2-CoffeeElad FDM-S2

If you’ve read my Elad FDM-S2 review (coming soon!) you’ll know that this little SDR packs a powerful punch for the price. Indeed, I would venture to say that the FDM-S2 offers the best value among the SDRs listed here. Its performance is uncompromising, comparing favorably to receivers $300-400 more in price. The S2 also provides native DRM decoding.  In short, the S2 makes for a fine DRM receiver.

Any negatives with this rig? Some users have reported diminished receiver performance in the presence of high-powered AM stations (fortunately, not an issue in the rural area where I live). Additionally, the Elad application has a greater learning curve than, say, the Perseus or the Excalibur (below). Still, I like the S2 so much that even though I already own a benchmark SDR, I’m planning to purchase the S2 after review.

The Elad FDM-S2 is available at Elad USA for $580.00.

PerseusMicrotelecom Perseus

If you’re looking for a benchmark SDR, it’s hard to overlook the venerable Microtelecom Perseus. Though it’s been on the market for many years now, the receiver architecture holds its own and is as robust as they come. Selectivity and sensitivity are absolutely superb: no matter the mode or band. Another benefit of the Perseus is that users can network their receivers with relative ease, sharing them with other Perseus users. Negatives? The Perseus price point still tops the charts at $1000. And while the supplied application works quite well, it lacks features found in other SDR apps, and the window cannot be resized (though numerous customer requests have been made). Still, the Perseus is likely to remain a DXer’s receiver of choice for years to come.

The Microtelecom Perseus is available at Universal Radio for $999.95. Click here to search eBay for a used Perseus.

WinRadio Excalibur

I have owned the WinRadio Excalibur since 2012, and it has become my primary home receiver. I have directly compared the Excalibur to the Microtelecom Perseus and the Elad FDM-S2 (above); any receiver performance differences are minor. As a radio broadcast archivist, I find the Excalibur to be the best receiver suited to capturing broadcasts, as it’s the only one in this group that can record up to 2 MHz of radio spectrum (and allow you to play back this recording later); up to three broadcasts can be captured simultaneously within that 2 MHz window. Negatives? The Excalibur application only works on Windows PCs. Additionally, it requires a dedicated 12V power supply, thus is less convenient than the RadioJet or FDM-S2 for travel and outdoor listening. Read my full review of the Excalibur by clicking here.

The WinRadio Excalibur is available directly from WinRadio for $945.95. Click here to search eBay for a used Excalibur.

Hybrid Stand-Alone SDR/Tabletops

The CommRadio CR-1

CommRadio CR-1a

The CommRadio CR-1a could be classed as either an SDR or a stand-alone tabletop receiver, as it fits both profiles. Furthermore, the CR-1a is as portable as nearly any of the portable radios mentioned above. In short, I really dig this radio! It’s beautifully engineered and mil-spec rugged; performance-wise, it’s hard to beat. Receiver sensitivity and selectivity are superb. The best part? The CR-1a has an optional internal battery that will power it for hours on a single charge. With antenna and fully-charged CR-1a, you will enjoy hours of outdoor listening while traveling [check out my recent travel review]. If you’re on the fence about getting an SDR or tabletop radio, grab the CR-1a; at $599.95, it’s a lot of kit for your investment. Click here to read my comprehensive review of the CR-1.

The CommRadio CR-1a is available from Universal Radio for $599.95 and directly from CommRadio for $599.99. Click here to search eBay for a used Comm Radio CR-1 or CR-1a.
