Using the Elad FDM-S2 on the $99 HP Stream 7 tablet

The HP Stream 7 Windows 8.1 tablet

The HP Stream 7 Windows 8.1 tablet

Regarding the Elad FDM-S2, Guy Atkins comments:

“This week I bought an HP Stream 7 tablet from the local Microsoft Store for $99, and it runs my Elad FDM-S2 receiver great! This recently introduced tablet is the perhaps the lowest priced new computer with Windows 8.1. I can even record the entire MW band, and play back the WAV files without audio stuttering. CPU load is an impressive 11-12%. Once you add a small OTG USB adapter you can plug in a USB hub and attach a wireless mouse receiver, the SDR’s cable, and other stuff. I was recording to a micro SD card (the slot is a bit of a pain, as you need to remove the back cover of the tablet. Recording to a USB external HD or SSD may also work). I also had an AC adapter powering the USB hub, as the tablet’s micro USB port cannot supply enough current for the Elad SDR.

This will be a neat, very portable setup for camping DXpeditions and when I want to take the SDR right to the termination of a phased loop array antenna for adjusting nulls. I do that now, but it’s more of a hassle with a regular laptop.

I presume I’ll be able to run the Afedri SDR-Net in “LAN mode” also but I’ll need to attach a USB-to-LAN adapter to the tablet first. A LAN rather than a USB connection is required for this particular SDR to have the bandwidth to handle all of medium wave at once.

Here’s a review of the 7-inch, Win 8.1 tablet: http://www.youtube.com/watch?v=SoPNzx8bcVQ. Also, when you buy it for $99 USD it includes a one-year subscription to MS Office 365, that can be used on two different devices. That’s worth $70 in itself.”

Wow–thanks so much for sharing this, Guy.

I’m very impressed you can record the entire MW band to an SD card and playback without stuttering. The quad core Atom processor must have enough horsepower to cope with the incoming data.

This setup would be ideal for field recording then taking the SD card back to the PC for analyzing later on a larger screen.

As you use this set-up, Guy, please keep us informed about any tips or quirks you discover along the way!

I found the Stream 7 at the following places online:

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.

Shoot-out results: Top ultra-portable shortwave

Tecsun-ShootOutThanks to all who participated in our ultra-portable shoot-out! A little over a week ago, I posted recordings of shortwave broadcasts, weak and strong, in an attempt to evaluate which recording–thus which radio–our listeners prefer. I conducted this test on the three radios pictured above: the Tecsun PL-310ET, the CountyComm GP5/DSP (Tecsun PL-360), and the Tecsun PL-380–among the most popular ultra-portables currently on the market. This test was “blind” in the sense that all three radios evaluated were merely labeled “Radio 1,” “Radio 2,” and “Radio 3,” respectively.

The samples

To refresh your memory, I’ve embedded the audio samples below for you to hear; but if you haven’t yet heard them, I encourage you to read our previous post before doing so. (If you’re already heard the recordings, simply skip this section.)

And now…the results!

The following chart shows how each radio scored out of a total of 106 (wow!) survey responses:

ShootOutRadios

Let’s start with the radio that scored lowest in this contest…

Radio 3: the CountyComm GP5/DSP (a.k.a., the Tecsun PL-360)CountyCommGP5DSP

Interestingly, the GP5/DSP consistently came in last in every category. I think a few factors outside of receiver performance led to this.

For some reason, the recorded audio of the GP5/DSP sounds out-of-phase.  Several of you noted this. The resulting sound almost mimics a “stereo” effect. No matter how many times I made recordings on the GP5/DSP, this feature predominated, and I eventually assumed it to be characteristic of this radio’s DSP.

But I’m wondering now, however, if there might be oxidation on one of the headphone jack conductors, or if the headphone jack on my unit is somehow faulty–?  Because of this, before conducting the medium wave shoot-out, I’ll try to clean the conductors with a little Deoxit to see if it makes a difference.

Unlike the PL-310ET and PL-380, the GP5/DSP can’t change AM bandwidths. On the strong recordings, I widened the bandwidths of the PL-310ET and PL-380 to 6 kHz; this improved their audio fidelity. On weak signals, I narrowed the bandwidth to 3 or 4 kHz, keeping both at the same level as I did so. While the GP5/DSP’s fixed bandwidth is well chosen, it simply couldn’t compete with the wider filters of the other two radios on strong signals.

Though the GP5/DSP (Tecsun PL-360) came in last, the irony is that most people who made comments on the survey form actually mentioned that the GP5/DSP was also a strong contender. Here are a few responder’s comments:

  • “The bassiness of Radio 1 was pleasing to listen to, but the clarity of radio 3 was also pleasing. All three sounded very good.”
  • “I was divided–Radio 1 seemed to provide the better audio on the stronger stations (not as muddy) yet Radio 3 beat it out on the weak stations and seemed to hold the station steadier (less fading) thereby providing a better audio to hear and understand.”
  • “I think if I were to place these three radios in order of “listening pleasure” based on the provided samples, my order would be 3, 1, 2.”
  • “By a small margin Radio 3 seemed to have the best signal to noise ratio and general audio quality across the range of signal strengths.”

Also notable:  the GP5 has one very distinct advantage over the other two radios, something that wouldn’t have been noticed in this test: its ETM function, which scans the whole band then automatically stores stations to temporary memory, is almost two times faster that that of the other radios. It also seemed to be equally accurate.

So, who would buy the CountyComm GP5/DSP (Tecsun PL-360)? Someone who likes this radio’s form factor, it’s stable AGC, and quick ETM scanning. Keep in mind, we are comparing this model with two of the best radios under $60, in my opinion. Had we compared the GP5 with most other sub-$60 radios, it might have won that shoot-out, and with ease.

Radio 2: The Tecsun PL-380

Tecsun-PL-380

The Tecsun PL-380 came in a very consistent second place in this shoot-out.

The ‘380 is one of my favorite portables on the market; for many years, it has been my go-to radio for one-bag travel.

Before recording the shoot-out, I guessed that the PL-380 might take first place. But up to this point, I had never actually compared it with either of the two other radios in this shoot-out. Listening to the blind samples, I tend agree with the results.  Still, the PL-380 is a great value and a fun little radio, one I can still easily recommend for travel.

Click here to search for the Tecsun PL-380 on Amazon.com, click here for eBay and click here for Universal Radio.

Radio 1: The Tecsun PL-310ETTecsun PL-310ET

As you can see from the graph, the Tecsun PL-310ET won our shoot-out in every category–and by a fairly wide margin:

UltraPortableShootOut

While comparatively few participants’ comments were specific to the PL-310ET (“Radio 1”), it’s interesting that these most often made note of this radio’s very close resemblance to the PL-380 (“Radio 2”).

The PL-310ET had only a slight advantage over the PL-380 to my ear, but it was enough; so along with most survey respondents, I took note of that advantage.

Now, I know this much: when people ask me whether they should purchase the PL-380 or PL-310ET, I think I’ll suggest the PL-310ET. In the end, it makes for a better travel radio because it also has an external antenna jack, one of the few sub-$60 radios that has this useful feature.

In summary, the Tecsun PL-310ET is truly a fantastic ultra-portable radio, and, at $48 – 52 US, it’s a real bargain, to boot.

Coming soon…our medium wave shoot-out!

When I find the time in the next month or so, I plan to test the same radios in a medium wave (AM) shoot-out. Weak-signal medium wave will put AGC circuits and internal ferrite antennas center stage. Please be patient, however, as these tests actually take time to put together and evaluate.  Again, your participation will be most welcome!

Mike’s mini review of the RadioShack Model 2000669 shortwave radio

RS-ShortwaveRadioRegarding the performance of the RadioShack Model 2000669 portable radio, SWLing Post reader, Mike, comments:

I picked one up today, and overall, I’m impressed. It does have complete coverage from 2.5 to 26.1 MHz as advertised, and overall, it has very good sensitivity and adjacent channel rejection for a small portable (in fact, the best I’ve heard from such). Sure sounds like some sort of DSP filter is involved. Reception is at least as good as my old Grundig Mini 300 and much, much better than a Degen DE22. Clipping an external long-wire antenna did not cause overloading (I was very surprised by this). AM BCB reception is actually quite decent: I was able to listen to several distant stations that were only 10 kHz from local ones. Audio is OK but not great, and the case does not stand up stably. I guess you can’t expect too much from a $30 radio. No case or earbuds are included.

By the way, if you go to a local Radio Shack store, be sure you get the internet price. We have two stores near my house; both had the radio marked as $39.99 instead of the $27.99 online sale price. The guys at the first store said “sorry, we can’t change the sticker price.” No sale. So, I went to the other store. When I pointed out the web price to the young women helping me there, she said, “this isn’t right” and called her manager over who overrode the store price with the cheaper one.

So, who makes this radio? Good question. The back of the case says “Custom manufactured in China for Radio Shack Corporation.” Maybe Tecsun?

Sounds like this may be a great portable for the glove compartment of a car, or to keep in your backpack/briefcase.

Thanks, Mike, and please share any other comments about this radio as you use it.

Sony ICF-SW100: difference between MKI and MKII

Sony-ICF-SW100

In response to our post about the Sony ICF-SW100, Michael comments:

“I’ve found that, with some patience and a willingness to search outside of eBay, that the ICF-SW100 can be found for under $250. It’s more than a fair bit of money for a shortwave receiver. If I had to take a guess at why it has held its value so well it would most likely be down to the amount of performance and features that still exist in a radio so small.

It is rather sensitive but even more so with an active external antenna or just a long wire attached to either the external antenna jack or the whip itself. It seems that the size of the whip itself (due to space constraints) limits the sensitivity of the radio. I use mine with a PA0RDT mini whip that I have constructed and the two work well very together. If you add a small outboard filter such as a NEScaf you have an entire station in miniature.

The fault with the hinges was only found on the MKI models. The MKII model was released by Sony primarily as a revision to solve the ribbon cable issue. You can tell a MKII from a MKI by looking at the lower right hand corner of the display part of the clamshell. If you see a rectangular shaped notch then it is a MKII. That notch is there for preventing the ribbon cable from being pinched between the two halves when the case is shut.

If you’re looking for a radio that is feature laden as well as exceptionally small then the ICF-SW100 is still an excellent choice.”

Many thanks for your comment, Mike!

Include in the CIA’s Survival Kit: the Sony ICF-SW100

CIAEscapeandSurvivalBag

I recently discovered an article on the excellent blog, LifeHacker, which describes the contents of the CIA’s Escape and Evasion Survival Kit.

The kit’s contents currently include:

Lifehacker believes the small bag used is the Maxpedition M-2 Waistpack. I like Maxpedition packs: they’re very durable, typically military grade, and reasonably affordable. But the M-2 is small–quite small.

This led me to thinking about über-portable shortwave radios I would carry in such a small pack for survival purposes. If I were a foreign operative, ideally, I’d want a shortwave radio that has SSB mode, in case my home country’s numbers station broadcast in SSB.

In reality, there are very few good radios that are so compact they could fit in the M-2 Waistpack.

A few that came to mind were the Tecsun PL-310ET or Tecsun PL-380, but the fit would be very tight, if at all; both radios are slightly wider and taller than the M2’s main pocket, which measures 5 x 3 x 1.5 inches. I then remembered the Kaito KA1102 that I owned a few years ago–a very portable radio, but it, too, would be too large at 143 x 88 x 28.50 mm.

But then, it hit me: there is one radio, which, though no longer on the market, would fit the bill (and the pocket)…

The Holy Grail of über-portable receivers: The Sony ICF-SW100

Sony-ICF-SW100

I have never owned an ICF-SW100, but I’d love to. Occasionally they show up on eBay, but prices range from $300-$800 depending on condition. That’s simply too pricey for my budget. Universal Radio has acquired used units in the past on rare occasions; these have sold between $200-400.

Then there are the lucky few, like my radio-listener buddy, The Professor. Remarkably, he tracked down (and knows I’ll never forgive him for it) an ICF-SW100 on Craig’s List for about $50! That was a steal.

Performance is superb for a radio this size. Not only does it have SSB mode, but selectable sideband sync detection.

One note of caution, should you be lucky enough to acquire one: the ribbon cable that connects the lower portion of the radio with the display (especially in the mark 1 production units) is known to fail. Fortunately, there are a number of videos (like this one) which walk you through replacement.

Honorable mention: the Sony ICF-SW1S

icfsw1cs

The ICF-SW100 predecessor, the ICF-SW1S (above), would easily fit in the M-2 Waistpack–it measures a mere 4.75 x 2.785 x 1 inches. Like its younger brother, it is highly sought after on the used radio market, and usually fetches $300+. The ICF-SW1S does not have a sync detector and lacks SSB mode. Still, as a broadcast receiver, it is truly superb for its size.

If you purchase a used ICF-SW1S, do ask the seller if all 6 original electrolytic capacitors have been replaced. If not, you may have to replace them in short order as the originals were known to fail. While not a repair for the faint of heart (as parts are quite small), there are several instructional sites and videos to help you.  Alternatively, you can send your ICF-SW1S to Kiwa to be professionally re-capped.

Any others–?

Do you know of any other high-quality shortwave portables out there compact enough to fit in the M-2 Waistpack?  Let us know!

The hunt is on…!
