Listening to a local station with the BC-348-Q until we lose power.
Here at SWLing Post HQ we’ve been under a Winter Storm Warning since yesterday–it’s not set to expire until sometime tomorrow. This storm hasn’t been all snow–it’s a mixture of snow and ice. If this continues, I fully expect to lose power at some point today.
In general, we’re prepared to handle this sort of thing: our refrigerator and freezer are powered by solar and completely off-grid, we have a super efficient RAIS woodstove to keep us warm and of course, we have a generator at the ready if needed.
Playing radio off-grid
As I write this post, I’m listening to the Signal Corps BC-348-Q (photo above) which is tuned to a local AM broadcaster. It’ll fill my shack with local news/tunes and its vintage valves will do a fine job warming this small room until the power eventually goes out.
When it does go out, I’ll switch to my blackout buddy, the CommRadio CR-1A.
I find that the CR-1A is nearly ideal for off-grid and field listening, as long as you have a good external antenna. The internal Li-Ion battery powers the thing for ages and it has an incredibly capable receiver.
Of course, I also have an Elecraft KX3 and KX2 which can be powered by battery, but I tend to use the CR-1A for broadcast listening and save the KX2/KX3 for off-grid ham radio QRP fun.
In addition, I have the new battery-powered CommRadio CTX-10 transceiver in the shack.
I’ve been receiving numerous emails about this particular field rig because there are so few CTX-10 reviews out there even though it’s been on the market since late July.
Please note that I’ve been giving the CTX-10 a thorough evaluation over the past few weeks and plan to publish my initial review in the next few days.
Even though I live in a very rural and remote area with little-to-no RFI, when the power is cut, my noise floor still drops . We’re not immune–like most homes, we have power supplies and devices that emit radio interference.
It’s funny: most urban radio enthusiasts I know don’t fear power outages, they prepare for and embrace them! When all of those RFI-spewing devices go silent, it’s simply amazing what you can hear from home on frequencies below 30 MHz with pretty much any receiver.
Personally, as long as I have a means of 1.) powering my radios, and 2.) making coffee (extremely important), I consider myself properly prepared.
I’ve always got those two points covered.
Bring it, old man winter! I’m ready to play radio!
My CommRadio CR-1a, with an internal lithium battery, is the perfect off-grid radio companion.
Monday night, the remnants of Hurricane Irma moved through western North Carolina. Because the SWLing Post HQ is at a high altitude compared with the surrounding area, we received higher than forecast winds. Still, we made it through fine and feel pretty darn lucky.
Yesterday afternoon, even though we maintained power throughout the storm, the utilities company cut power to our road due to a tree that had fallen on a pole that also supported a transformer. It’s a tangled mess. Since there are about 17,000 without power in our rural area, it’ll be some time before power is restored to our road–likely late Friday evening or sometime this weekend.
Loss of power isn’t a major problem for us since our refrigerator and freezer are off-grid and solar powered 100% of the time anyway. We also have a propane stove to cook on and plenty of charged battery packs and flashlights (and at least half a dozen HumanaLights in service).
On the plus side? Even though our house is pretty RFI free, when the power is cut, it’s amazingly radio quiet.
I listened to RRI last night on the CommRadio CR-1a (see above). Later, I sat in bed with the pilot run CC Skywave SSB and tuned through the 31 meter broadcast band, the 40, 80 and 160 meter ham bands and the mediumwave broadcast band. Happy to say that the Skywave SSB did an amazing job–and propagation was decent. Reception was so good, it felt like I was camping in a national forest. Just makes one realize how all the devices in our home add to that RFI noisy environment.
We count ourselves lucky as news from all of the areas that took the full impact of Hurricane Irma is simply gobsmacking.
This morning, I listened to a few HF nets on the 80 and 40 meter bands with the Digitech AR1780–I noted no less than five hams reporting that they were operating on generator power. I believe this hurricane has caused one of the largest power outages we’ve ever had in the US due to a natural disaster.
Note that since I don’t have power at home, I also don’t have Internet service–keep this in mind if you attempt to contact me this week. I will post quick updates to the SWLing Post while I’m in town, however I will certainly fall behind on correspondence. Thanks for understanding.
If you’ve been considering the purchase of a CR-1a receiver, note you might find one on the used market (check with Universal Radio) as some owners upgrade to the CTX-10 transceiver next year. I expect the CTX-10’s receiver to be on par with the CR-1a, if not a little better.
On that note, I plan to review the CTX-10 and, of course, give its general coverage receiver a thorough workout on the broadcast bands once the unit has been released in 2017.
Despite the often-expressed view that shortwave may be on the decline, if one were to look at this year’s shortwave technology alone, the truth would seem to be anything but. Remarkably, 2015 has been a great year for the shortwave radio listener, as several models of portables, tabletops, and SDRs have been either introduced or improved.
The following is a basic, easy-to-follow buyer’s guide to some of the best receivers on the market currently. This guide is, by no means, comprehensive; rather, it’s a selection of rigs I have tested, some of which I now own. It builds on the guide I published in the November 2014 issue of TSM, and highlights innovations since that issue, while still acknowledging the contributions of previous models.
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 consider a compact shortwave radio.
Typically, there is a performance compromise with compact radios: they don’t always have the sensitivity of 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.
The Eton Traveller III
Eton Traveller III
Eton has once again refreshed the design of its popular “Traveller” series of compact receivers: their latest is the third edition, the Eton Traveller III. I’ve owned the past two versions of the Traveller, and having learned to appreciate these, was eager to get my hands on the newest Traveller III. As the name implies, this is a great little radio for the international traveler; it not only has shortwave, AM and FM bands, but it also has a world clock that can easily be switched from the front panel, a useful alarm function, and great built-in speaker. New to the Traveller III is FM RDS: a great way to capture FM station identification when visiting a new city. The key lock is prominent on the front panel and the included padded nylon case is one of the most rugged I’ve seen in years. Performance is what I’ve come to expect from the Traveller series: superb AM (mediumwave) reception, great FM reception, and capable shortwave reception. It lacks the multiple bandwidths found in other similar DSP radios, but my impression is that the default bandwidths are adequate for multi-band listening.
Only a couple of weeks before the Christmas holiday of 2014, C. Crane introduced a compact portable that truly impressed me: the CC Skywave. The Skywave is as compact as any other ultralight radio, but adds a host of features that has made it an invaluable radio for my one-bag air travels. The CC Skywave covers the following bands: Shortwave, AM, FM, Weather, and Aviation. It’s a comprehensive toolbox of frequency bands and listening modes which only lacks, sadly, SSB.
Ergonomics are excellent for such a small portable. It’s easy to use, as well: I only needed to reference the well-written manual for a few functions. I find the CC Skywave to be very sensitive on shortwave and mediumwave, rivaling radios that cost much more.
One negative I’ve learned through readers of the SWLing Post is that the first production run of the CC Skywave was prone to overload in the presence of strong local broadcast stations. C.Crane have confirmed that this has been addressed in the latest CC Skywave production run and is no longer an issue. To insure you’re receiving a unit from the latest production run, consider purchasing directly through CCrane.
CountyComm––a retail distributor of products created primarily for use by the US government––introduced a new shortwave portable late in 2014: the GP5/SSB. The GP5/SSB came about as a result of a large order CountyComm received from a US government department for an “inexpensive, small portable, AM/FM/SW radio with SSB” for emergency supply caches and diplomatic posts. Like its predecessor, the GP5/DSP, the GP5/SSB has a vertical form factor, much like a handy-talky, and a detachable/rotatable ferrite bar antenna that greatly improves AM/mediumwave reception. The GP5 series is limited by a small internal speaker that sounds somewhat tinny; it also lacks a direct entry keypad. Still, with a pair of headphones and some careful memory allocation, the GP5 is a pleasure to use.
If you’re looking for an ultra-portable radio with SSB, then the GP5/SSB is a very good choice. (It may, in fact, be the only ultra-portable SSB choice currently on the market). While the SSB performance can’t compare with larger, pricier receivers, or 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, and why this rig has excellent frequency coverage in all modes, with good sensitivity/selectivity and designed for portable, one-handed operation. In fact, CountyComm has even designed and manufactured (and 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.
I was surprised this year when Sangean introduced its latest compact/travel receiver, the ATS-405. I had heard rumors that Sangean may have been leaving the shortwave radio scene, so was pleased to learn that Sangean was not only still invested in the hobby, but innovating. Indeed, the ATS-405 has features that have not yet been included on small DSP-powered portables: specifically, the ability to control squelch, tuning mute, and soft mute.
The ‘405 is a decent little radio with a great deal of functionality and features for a rig in its price class. But overall, its performance seems rather mediocre. If you primarily listen to FM, you’ll be pleased. If you’re a mediumwave listener, you’ll be pleased only if you don’t mind the 800/1600 kHz DSP birdies which plagued both of my review units. If you’re primarily a shortwave listener, you’ll need to carry a clip-on wire antenna to bring the sensitivity up to the level of similarly-priced receivers. I also found performance variations between my two review units; an indication that quality control is somewhat inconsistent at the factory.
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 with a few notable exceptions, the ability to receive single-sideband.
The Tecsun PL-680
The latest Tecsun full-featured portable––the PL-680––appeared on the market in February this year. Cosmetically, the receiver is nearly identical to the Tecsun PL-600, but with the added features of the Tecsun PL-660. Indeed, in terms of features and comparing them with that of the venerable PL-660, there are no obvious additions on the PL-680. The PL-680 has been improved, however, in its shortwave reception. The PL-680 is both slightly more sensitive and has a more stable AGC (Automatic Gain Control) than the PL-660. If you are primarily a shortwave radio listener and wish to have one of the best sub-$200 receivers currently on the market, the PL-680 may be the rig for you.
On the other hand, if you are primarily a mediumwave DXer and already own the PL-660, you will likely want to pass on the PL-680. The PL-680’s mediumwave reception is simply not as good as that of the PL-660. The PL-660 is both more sensitive and has a lower noise floor on mediumwave.
Note that since its introduction, inventory of the PL-680 has fluctuated; the primary retailer is Anon-Co in Hong Kong and on eBay. Price is $95 US (plus shipping from China).
The Eton Satellit
Last year, Eton released the Satellit: a new full-featured portable, essentially replacing the venerable Grundig G3, but carrying the name of the flagship Grundig Satellit series.
The Satellit has many of the same functions as the Grundig G3, and has a near-identical form-factor, but sports a new amber backlit display, multiple bandwidths, and a double-jointed telescopic antenna. The Satellit performs admirably on the AM/mediumwave bands, quite well on the shortwave band but, most notably, performs brilliantly on FM. The audio fidelity from the built-in speaker is quite robust; indeed, it’s among the best in its class. The key layout and ergonomics are similar to the Grundig G3 and G5; meaning, the radio is quite simple to use. One negative is that the Satellit mutes between frequencies while tuning, however, this is minimal in the most recently-updated production runs. I’m very pleased that all of the new Eton radios lack the tactile rubber coating found on some previous models, for while the coating works excellently to improve one’s grip on the radio, over time it can become sticky to the touch (if you find this to be a problem, here are several techniques to clean the sticky residue: http://bit.ly/1KQN8TX).
At time of print, the Satellit is generally available for about $180-190 from a variety of retailers, including Universal Radio and Amazon.com.
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.
The Elad FDM-DUOr
If you’ve been thinking of purchasing an SDR, but really want a traditional front-panel tabletop receiver, the Elad FDM-DUOr may be for you. I’ve included the FDM-DUOr under the tabletop heading because it is, in fact, a tabletop receiver, with the features of a tabletop such as a front panel, knobs, display, and capability to operate independent of a PC. However, if you choose to hook it to a PC, you unleash a full-fledged SDR and a wide array of features. The FDM-DUOr is built on the same receiver and software as the FDM-S2, one of my favorite sub $1000 SDRs. The FDM-DUOr also sports 10 selectable and customizable filter preselectors and an internal switch box for use with an external transceiver.
At time of print, Elad is seeking FCC approval for the FDM-DUOr in order to distribute these units in the USA. The FDM-DUOr is currently available in Europe via the Elad online store: Price is 899.00 €.
The CommRadio CR-1a
US-based manufacturer CommRadio introduced the CR-1 in 2013––an amazingly rugged, portable receiver, and essentially a small tabletop SDR. I’ve used mine in travels and at home; the built-in rechargeable battery will power it for hours, it’s built to a mil-spec standard, and it performs like a champ.
In 2014, CommRadio increased the SDR potential of the CR-1 by updating with a new model: the CR-1a. In 2015, CommRadio continued to add features to the CR-1a through firmware and software upgrades, such as a new Spectrum Viewer SDR application, and 3D-Waterfall for Windows PCs.
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 performance, none are stand-alone. But while I was never 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. The ease of doing so is incomparable, and the functionality simply incredible.
The Elad FDM-S2
Elad FDM-S2 and the new SPF-08 preselector
If you read the Elad FDM-S2 review in the November 2014 issue of TSM you’ll know that this little SDR packs a powerful punch for the price. FDM-S2 performance is uncompromising, comparing favorably to receivers $300-400 more in price. The S2 also provides native DRM decoding; it’s a fine DRM receiver.
Users who live in the vicinity of high-powered AM stations will be pleased to know that Elad has developed an outboard preselector box that pairs with the FDM-S2––the new SPF-08, which covers the amateur radio bands. Elad already has a broadcast band version of the SPF-8 in development. The SPF-08 enclosure is the same size as that of the FDM-S2 and couples with it directly via a port on the back of both units.
The SDRplay RSP was one of the most pleasant surprises I encountered in the world of software defined receivers this year. I published a review of the RSP in the May 2015 issue of TSM; in short, I was amazed at the performance of this $149 SDR. While it doesn’t have its own proprietary SDR application, it is compatible with some of the most popular free applications on the market: SDR Console, SDR Sharp, and HDSDR to name a few. SDRplay developers are even testing a Raspberry Pi application for the RSP.
Since the time of my review, SDRplay has updated the RSP to include gapless coverage from 100 kHz to 2 GHz––talk about wideband coverage!
If you have been hesitant to invest in a benchmark SDR, or simply want to explore the world of SDRs on a small budget, the SDRplay RSP is a no-brainer. Without a doubt, it packs a lot of performance in a tiny, affordable package. The SDRplay user community is also very active and routinely pushes the boundaries of this little receiver.
The Cloud-IQ is the latest software-defined receiver from the US-based company RFSPACE. The Cloud-IQ offers two modes of operation:
the “IQ mode,” which provides 24-bit IQ streaming to your PC over an ethernet cable (much like the RFSpace NetSDR).
the stand-alone “cloud mode,” which includes a built-in internet server. In cloud mode, according to RFSpace, “the receiver performs the tuning and demodulation of signals and transmits the demodulated information back to a PC, OS-X, Linux, or Android client anywhere in the world.”
RFSpace is essentially one of the first SDR manufacturers to include built-in SDR streaming functionality, something that has been somewhat complicated to implement in other SDRs.
The price point is also favorable at $629.95 through Ham Radio Outlet, Amazon, Astroradio and ML&S. Availability has been quite limited this year, but more production runs are planned for the near future. I plan to review the RFSpace CloudIQ in late 2015 or early 2016, as soon as a unit becomes available.
Many thanks to SWLing Post reader, Grzegorz Jasionek, who notes that CommRadio has just released a firmware update for the CommRadio CR-1a that includes a new Graphic User Interface (GUI) with a 3D spectrum display.
The CommRadio Dropbox site has an 18 minute video showing how to operate the GUI and the various features; CommRadio recommends you watch the video prior to using the GUI for the first time.
“I have continued to run A/B comparisons between my CR-1a and an NRD-515. Digital to Analog competition.
My NRD-515 has been a station favorite for many years. I find the two radios are pretty much equal in terms of performance. Sensitivity between the two are even. The wide range of BW filter options on the CR-1a are a real plus. My 515 has the stock 2.4 mechanical and the 500 hz cw filter.
The CR-1a with the portability, long battery life and internal speaker makes this one awesome receiver. I plan to use this radio when camping and recharging via a small solar panel should be a snap. A small QRP transmitter with T/R switching is the works.
I was really blown away by receiving an email from the president of Comm Radio concerning feedback I left on their website.
Big performance in a small package. 5/5+”
Thanks for your comment, Ray! Wow–The JRC NRD-515 is a classic. It’s great to hear that the CommRadio CR-1a stacks up so well against this benchmark.
Like you, I love the portability of the CR-1/CR-1a line. The internal battery powers it for hours at a time. I’ve hinted to CommRadio that they should design a small companion transmitter for portable QRP–link the two together and that would be one cool piece of kit!
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.
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.
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 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 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-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.
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.
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).
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.
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.
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 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-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-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.
At 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.
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.
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.
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.
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.
Bonito 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.

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.
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.
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 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.
