The Worldwide Listening Guide 7th Edition: now released

WWLG-7th-Edition

Many thanks to SWLing Post contributor, Thomas Ally, who notified me that he has just purchased a copy of the WWLG 7th edition through Amazon.

Here’s the description of the new edition:

New, fully-updated 7th edition provides a complete guide to listening to radio in all of today’s formats: “live,” on-demand, WiFi, podcast, terrestrial, satellite, internet, digital, and of course analog AM, FM, and Shortwave.

The introductory section explains all of the newest delivery methods for radio, and the devices used to access broadcasts from around the World at any time of day or night. Listening to programs from distant lands is no longer a late-night activity dependent upon shortwave propagation conditions. There are thousands of radio stations worldwide that use the Internet to stream their broadcasts. Traditional radio is being augmented by computers, tablets, smartphones, satellites, WiFi receivers, and multiplexed digital transmission methods, greatly enhancing the listening experience.

The Worldwide Listening Guide shows you how to access all of this audio content using these different delivery platforms. The Guide is focused on English language broadcasts that can be heard in North America. There is a comprehensive listing of more than 3500 programs. These are then placed in separate categories by program type, such as news, music, talk, current affairs.

The WWLG 7th edition is also available from Universal Radio, the W5YI Group and Ham Radio Outlet.

Whereas the WRTH–also just released–is a guide to stations and broadcasts, the WWLG is a guide to content and programming. I always have copies of both in my shack.

Thanks, Tom Ally, for the tip!

The SWLing Post 2015-2016 Shortwave Radio Buyer’s Guide

This article originally appeared in the November 2015 issue of The Spectrum Monitor magazine:


FourRadiosAbstract2

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.

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 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

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.

The Eton Traveller III is available from Universal Radio, Amazon.com and more outlets via Eton. Pricing ranges from is $55-60 US.

The C.Crane CC Skywave

The C.Crane CC Skywave

CC Skywave

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.

The CC Skywave is sold by Universal Radio, Amazon.com and directly by C.Crane. Price is $89 US.

The CountyComm GP5/SSB

The CountyComm GP5/SSB

CountyComm GP5/SSB (Tecsun PL-365)

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.

The CountyComm GP5/SSB is available from Universal Radio and directly from CountyComm.

The Sangean ATS-405

The Sangean ATS-405

Sangean ATS-405

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.

The Sangean ATS-405 is available via Universal Radio and Amazon.com. Price is $89 US.

Other compact/travel radios

In the 2014 Buyer’s Guide we included several other compact travel radios worth considering: The [original] Kaito KA1103/Degen DE1103, Tecsun PL-310ET, and the Tecsun PL-380 to name a few.

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 with a few notable exceptions, the ability to receive single-sideband.

The Tecsun PL-680

The Tecsun PL-680

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

The Eton Satellit

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.

Other full-featured portables

In the 2014 Buyer’s Guide, we included several other full-featured radios that are still certainly worth considering: The C. Crane CCRadio-SW, Sangean ATS-909X, Sony ICF-SW7600GR, Tecsun PL-600, Tecsun PL-660, and the Tecsun PL-880.

Hybrid Stand-Alone SDR/Tabletops

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

The Elad FDM-DUOr

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

The CommRadio CR-1a

CommRadio CR1-a

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.

CommRadio CR-1a owners only need to update their firmware and download software to use the new feature. The CR-1a is priced at $599.95 US, shipped, and includes a battery through Universal Radio––good value for a quality piece of kit. CommRadio also sells the CR-1a directly through their website.

Other tabletops

In the 2014 Buyer’s Guide, we included several other tabletop radios, including the Alinco DX-R8T and the Icom IC-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 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

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.

Both the Elad FDM-S2 and SPF-08 are available via Elad’s online store: http://ecom.eladit.com/

The SDRplay RSP

The SDRplay RSP

SDRplay RSP

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 SDRplay RSP is available at SDRplay.com and, in the US, at Ham Radio Outlet.

The RFspace Cloud-IQ

The RFspace Cloud-IQ

RFSpace CloudIQ

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 OutletAmazon, 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.

Other SDR/IF receivers

In the 2014 Buyer’s Guide we included several other SDRs and IF receivers worth considering, including the Bonito RadioJet IF-Receiver 1102S, Microtelecom Perseus, and the WinRadio Excalibur. Additionally, note that the affordable Airspy SDR will soon have a new converter to cover HF down to 1kHz–look for a review in 2016.

The New Degen DE1103 DSP: First impressions & review

IMG_20151124_085005760_HDR

When I discovered that Degen had recently refreshed the receiver design of the DE1103, I was intrigued, to say the least. The original DE1103 sported some serious performance for a sub-$100 receiver.

IMG_20151126_165751594_HDR

The 2015 model of the Degen DE1103 implements a DSP chip (the Silicon Labs Si4735-D60).

Yet I was on the fence about purchasing the new DE1103. Why? In truth, I never fell in love with the original DE1103. While I appreciated the 1103’s unique analog-style digital display, I never got used to its quirky ergonomics. Degen had quality control issues, too: I had to return two faulty units before getting one that worked as advertised (incidentally, I had a similar problem with the Kaito KA1102).

Then last week, SWLing Post reader, Ron, contacted me. He had purchased the new DE1103 from Hong Kong-based eBay vendor Bigbargainonline.

IMG_20151124_085138034_HDR

Ron kindly provided the SWLing Post with his impressions of the DE1103, as follows:

Performance is roughly on a par with the earlier dual conversion version. This one is just as hot, but no hotter.

If you were thinking a GP5 on a bigger ferrite bar, yes…and no.

There is one major gripe…[this unit] will not remember frequencies set with the BFO on, like the earlier dual-conversion version did. Instead you have to turn the BFO on for each memory frequency [for which you] need it.

One thing [I] noticed right off was the almost complete lack of AGC “pumping” on CW and SSB that all earlier versions had (yay!) but this plus comes at the cost of having the BFO “remembered” in memory.

Zero-beating (or centering) the BFO to null on WWV and local AM stations to check alignment was…strange. At null beat the BFO seems to quit for a second. It is fine
either side of zero beat, however.

This is doubtless due to Tecsun’s adapting the Silicon Labs IC to a full range BFO like this. Recall the same IC in the GP5 features Upper and Lower selection on CW/SSB.

This 1103 DSP version also has the GP5’s slight tuning mute, not a problem.

But for ease of operation in CW/SSB mode, the GP5 is [much] better IMO.

Ron also notes that he wasn’t pleased with the DE1103’s longwave performance and didn’t feel the mediumwave and shortwave reception was an improvement on the original DE1103.

He decided that he would sell this DE1103 and gave me first dibs, so I bit the bullet. I was eager to compare the new DE1103 with some of the other DSP-based portables in my collection. Ron dispatched the DE1103 immediately–it arrived a few days ago, but I didn’t have a chance to test it until yesterday.

IMG_20151126_165748588_HDR

I took the Degen DE1103 outside, sat it on the tailgate of my truck and put it on the air…

I tuned around the mediumwave band and picked up all of the local benchmark stations. Same with FM. So far, this tuning confirmed Ron’s assessment of the DE1103: it didn’t surpass the original.

But the shortwave bands were a different story.

As I tuned around the HF bands, the DE1103 seemed to receive quite a lot signals.  But in most instances, I could hear local AM broadcasters bleeding in, as well. Indeed, imaging was prevalent across the shortwave bands–the receiver was obviously being overwhelmed by a local broadcaster.  Unfortunate.

Could strong interference account for this? While there are local AM broadcasters around, they’re not exactly “blow-torch” stations. Indeed, I’ve never had overloading issues with other shortwave portables I’ve used in the same location–not even with my Kaito WRX911!

Imaging was prevalent on the DE1103 when it was tuned to pretty much any audible shortwave broadcaster.

Here’s a video of the Degen DE1103 tuned to the Voice of Greece on 9,420 kHz:

What you’re hearing in the audio is a local broadcaster bleeding in. Note that when I tune off-frequency, no imaging is heard.

Wondering if something had changed locally–and just to be fair–I pulled out my Sony ICF-SW100 and sat it next to the DE1103. The Sony had no issues.

This time, I tuned to WWV on the 19 meter band and compared the two receivers:

As Dan Robinson expresses it, the ICF-SW100 “wipes the floor” with the DE1103. There’s no hint of overloading in the SW100.

My buddy, Ron, is clearly a keen radio reviewer; obviously he didn’t hear overloading on the shortwave bands where he tested the rig, else he would certainly have mentioned it. The location where I tested the DE1103 does have some local broadcasters in the area, but no clear channel or high-power stations; in short, there’s no likely interference within a ten-mile radius to account for this debilitating performance problem.

Too bad…!

Obviously, the new DSP version of the Degen DE1103 is especially prone to imaging on the shortwave bands. In fact, it’s the only receiver I’ve ever tested that has overloading issues at this testing location (where I tested the original Degen DE1103, by the way).

My assessment? Avoid the new Degen DE1103.

A much better receiver with SSB for roughly the same price would be the venerable Tecsun PL-600 ($89.99 at Amazon and $89.95 at Universal Radio). If SSB reception isn’t necessary, you might also consider the CC Skywave or the very affordable Tecsun PL-310ET.

eBay: Mario considers the Time Out Radio Bench

Time-OutRadio-Bench-001

Many thanks to SWLing Post contributor, Mario Filippi (N2HUN), who writes:

Hi Thomas,

For hams and SWLs that have a lot of clutter, a great idea, reminds me of a foot stool that has been re-purposed for radio buffs. Nice idea, good price, free shipping, what’s not to like? My spending finger’s getting itchy hi hi.

Click here to view on eBay.

I’m with you, Mario: this is not a bad price for a useful and portable shelf that is even made here in the USA (Kentucky). I could see using one on Field Day where horizontal space is often limited on club tables.

It appears that the seller (a ham: Ron, KK4RON) purchased a large number of these in a deal. He writes this in the product description:

These benches are great for setting up a compact ham station or use 3 for a surround set up , They also stack nicely if you only have a narrow space available. Go UP rather than out.

These are very sturdy and well made in the USA by a factory in Kentucky , the surface is a very durable and easy clean kitchen cabinet material (Formica) on 3/4″ wood so screwing on mounting brackets and mike holders and such is very easy

These were intended to sell for $49.95 but the company that ordered them went out of business before they had payed the factory so the factory got stuck with literally thousands of these finished and ready for sale.

We were able to acquire there entire inventory including boxes and packaging at a fantastic price but that is also why we are limited to 8 colors and 2 top colors. But these are very well built from a factory (not home made) and just perfect for mounting several radios to and cleaning up your bench.

Again, many thanks, Mario, for sharing this find (and perhaps it’s time to get yourself an early Christmas gift?)!

Updated release: “At The Tone: A Little History of NIST Radio Stations WWV & WWVH”

AtTheTone

Almost five years ago, I wrote about a unique collection of archived recordings called At The Tone: A Little History of NIST Radio Stations WWV & WWVH.

Producer Myke Dodge Weiskopf recently released a new and expanded edition of At The Tone which is now available for purchase and download.

Myke describes the update:

“The new edition significantly expands on the previous CD reissue from 2009. It incorporates a bunch of tapes sourced from the original announcer tracks made by Jane Barbe herself for WWVH, as well as a handful of vintage broadcast recordings previously left out of the set. I’ve also taken the opportunity to clean up and remaster the set overall, so it’s a much more cohesive listening experience as a body of work.”

Click here to purchase the new digital edition of At The Tone.

Please comment!

Myke is also giving away a free download of At The Tone to a lucky SWLing Post reader!

Simply comment on this post, noting the first time you heard WWV: note both the year and the model of receiver used.

For example, I would comment: “The year was 1976 and the receiver was an RCA Model 6K3 console radio.”

Myke will pick a winner from the comments next Wednesday (November 25th). If the winner has already purchased the expanded edition of At The Tone, Myke will reimburse the purchase. Good luck!

Tecsun S-8800 launch possibly first quarter 2016

Tecsun-BCL3000-001After learning about the new Tecsun S-8800, yesterday, I contacted Anna at Anon-Co and asked for any information regarding specs and availability.  Anna replied:

“Regarding the S-8800, there is no information available of when this will be actually launched. I think that the absolute earliest could be some time in January, but I expect that it will be after Chinese New Year. To be honest, it is very difficult to say at this moment. There isn’t much information available about it yet.

Supposedly it is pretty much the same [chassis design] as the existing BCL-3000, but it will be a PLL radio with DSP IC. It should have SSB features, but other details (like SYNC) I’m not aware of at this moment. I’m hoping to hear more about this soon.

Anna will contact me as soon as she has more info about the S-8800 features and availability.
