The best general coverage transceivers for shortwave listening

This article originally appeared in the May 2014 issue of The Spectrum Monitor Magazine.


Icom-IC7200

The Icom IC-7200 has an excellent general coverage receiver

Like many amateur radio operators, I became interested in HF radio because of my real passion for shortwave radio listening. During my first fifteen years as an SWL, I relied on portable receivers, in my case, the Zenith Transoceanic, Realistic DX-440, and Grundig YB 400. The Zenith was my home radio; I traveled with the DX-440 and YB400. I felt like I had the world at my fingertips.

In the mid 1990s, as an undergraduate, I decided that I would pursue my ham radio license–while on my student budget, I dreamed about upgrading to a proper tabletop receiver like a Kenwood, Icom, JRC or Drake. But when I found out the real cost of buying an HF transceiver (gasp!) I realized that all of my resources would go into a transceiver, and the receiver would just have to wait.

The Icom IC-735 general coverage transceiver

Then, as I was studying for my license in 1997, ham buddy Eric McFadden (WD8RIF) invited me over to his house to test drive his Icom IC-735 transceiver. Eric, along with another friend/elmer, Mike (K8RAT) encouraged me to look for a used IC-735 for an affordable first HF radio.

I recall very well tuning around the ham bands at Eric’s QTH and being most impressed with how the IC-735 seemed to pull signals out of the static. It was my first time ever tuning a tabletop rig, and I was instantly hooked. Later, I asked Eric if the ’735 could also tune in shortwave radio broadcasters? His energetic response: “Sure! The ‘735 is general coverage,” then demonstrated by tuning to the 31M band.

Needless to say, I was absolutely amazed by the number of stations one could hear on this ham radio transceiver. Of course, its sensitivity surpassed anything I had ever owned, especially considering that the rig was hooked up to a proper outdoor wire antenna. I realized then that a ham radio transceiver and receiver–in the same radio–were within my financial grasp.

So, what is “general coverage”––?

A ham transceiver with “general coverage” means that the receiver portion of the radio is not limited to the ham bands only; these receivers typically receive between 100 kHz and 30 MHz (i.e., the full medium and shortwave radio spectrum). Many transceivers, starting in the 1980s, employed a general coverage design as a feature of the radio. Some radios implemented general coverage receiving better than others. In most cases, there was a compromise to performance when the receiver was opened to general coverage reception, so many manufactures held to a ham-band-only platform to optimize performance where hams sought it most. Today, receiver architecture can better accommodate general coverage without compromising sensitivity and selectivity on the ham bands.

Still, in 1997, my Icom IC-735 met all of my ham radio and SWLing expectations. For years, in fact, it was my main SWLing rig. Was the IC-735 as good as a proper tabletop receiver? No. The truth is that its filters and performance were most favorable for the ham radio bands. But as I mentioned, this compromise is much less profound in current transceiver design, and general coverage is status quo.

Benefits of general coverage

While the benefit of having a transceiver that can tune the full broadcast band may seem obvious, there are two reasons I always have at least one general coverage transceiver in my radio arsenal:

  1. Since I like to travel and save space, a small general coverage transceiver (e.g., the Elecraft KX3) kills two birds with one (portable) stone;
  2. If an emergency, such as a dire weather event were to occur, general coverage will allow me the ability to monitor international broadcasters and local AM (mediumwave) stations while still performing any emcomm (emergency communications) duties.

Another advantage to owning a proper HF transceiver is that, if you currently do not hold an amateur radio license, this may just be the push you need to get your ticket! All you’ll need to do is take two multiple choice tests (Technician and General) to unlock the full potential of your HF transceiver, and you’ll soon enjoy hamming it up with the rest of us.

Cons of general coverage

As I mentioned, general coverage transceivers can present something of a compromise in performance; after all, the rig’s main duty is to perform on the ham bands. Here are a few compromises to be aware of:

  • With a few exceptions, purchasing a ham transceiver is pricier than purchasing a comparable dedicated broadcast receiver
  • AM filters are often much narrower than broadcast receiver filters
  • In many radios, you may be faced with a choice of optimizing filter selections for ham radio use (SSB or CW) or broadcast use (wide AM filters, etc.)
  • Older general coverage transceivers (circa 1980s and 90s) may have somewhat compromised ham band receive performance
  • Some general coverage transceivers may actually lack AM mode. All broadcast reception will basically be tuned via SSB (or better known as ECSS)
  • General coverage transceivers typically lack synchronous detection

Another consideration: while anyone can purchase a general coverage ham radio transceiver, until you hold an amateur radio license with HF privileges, you cannot legally transmit using your radio. I doubt that any readers would consider doing this intentionally, but again your radio is designed to transmit, so this could be done accidently especially if you’re not familiar with transceiver functions. Transmitting unintentionally can have more than legal repercussions: 1) if you transmit with a mis-match between your transmitter and antenna, you could harm the finals in your transceiver; 2) you could damage your radio and/or antenna if using a receive-only antenna (like a mag loop); and 3) you could even receive RF burn. To avoid this, and make it foolproof, search the web for modifications to temporarily disable “transmit” on your radio if indeed you never intend to transmit.

A note about power supplies

My trusty Astron Power Supply

My trusty Astron Power Supply

Unlike stand-alone receivers, most general coverage transceivers require an external DC power supply. If you do not have a power supply, you will need to fit this into your budget. Power supplies can be costly, but also an investment in longevity. With a little knowledge up front, you can be selective and save on your power supply purchase. As I have been using the same power supply (an Astron RS-35A) since 1997, I turned to my friend Fred Osterman, president and owner of Universal Radio, for suggestions on power supplies currently in production.

Fred pointed out that if your only goal is to power a transceiver for the receive function, there is no need to invest in an expensive power supply. He suggests a reliable, regulated power supply, such as their popular $35 (US) Pyramid PS-4KX: at 3.5 amps; indeed, the PS-4KX will be more than enough power for any transceiver in receive mode.

Of course, if you plan to transmit at full power–and unless you have a QRP radio–you will need a power supply that can handle the load. For this purpose, Fred suggests two excellent options:

Again, I’ve had my trusty Astron RS-35A since 1997, so once you’ve invested in a good power supply, you should be all set for many years–and radios–to come.

My old 1 amp regulated laptop power supply is more than adequate for SWLing on the Elecraft KX3

Transceivers: Good bets for $1,600 US or less

There are dozens of general coverage transceivers currently on the amateur radio market. Indeed, I don’t believe there are any rigs now in production that do not have a general coverage receiver, or at least the option to add it. Prices vary greatly, but I will assume that most SWLs that are considering the leap into amateur radio will want a radio that costs less than the price of a tabletop radio/transceiver combo. Just to keep things simple, we’ll limit our list to $1,600 US or less, beginning with the least expensive option.

Alinco DX-SR8T ($510 US)

The DX-SR8T ($510 US) is one of the most affordable general coverage transceivers on the market. To be clear, the DX-SR8T lacks many of the frills and features of pricier rigs, but it’s a surprisingly good transceiver and, of course, general coverage shortwave receiver. Indeed, Alinco actually markets a receive-only version of this radio (the DX-R8T, $450US); it is identical in every respect to the DX-SR8T, but simply has no transmit function.

While I have only used the DX-SR8T on a few occasions, I have spent a couple of years with the DX-R8T, and even reviewed it extensively in the SWLing Post. My DX-R8T began life as a review unit that I purchased––it was an early production unit, and even retained the transmit LED indicator found on its sibling, the DX-SR8T. Consider paying the extra $60 US for the DX-SR8T, and you’ll have a basic, full-featured transceiver.

You can purchase the IC-7200 from Universal Radio or other ham radio equipment retailers.

The Icom IC-7200 ($900 US)

The IC-7200 delivers a lot of performance for a sub-$1,000 price. Its general coverage receiver will rival that of the venerable R75, and its AM filter can be widened to 6 kHz. Ergonomics are better than average. Plus, it has Icom’s twin passband tuning: the IC-7200’s general coverage receiver actually tunes from 30 kHz all the way to 60 MHz. The IC-7200 is a fantastic value.

The Elecraft KX3 ($900 kit; $1,000 factory pre-assembled)

The Elecraft KX3

The Elecraft KX3

The Elecraft KX3 is my general coverage transceiver of choice. There’s so much about this radio that I like: it’s nearly as compact as my portable shortwave radios, it’s a full-featured transceiver, it can operate on batteries, it has good ergonomics, and is made and supported by Elecraft, right here in the USA.

Its sensitivity and selectivity rival radios three times its price. The only negative I can point out about the KX3, in comparison with many other general coverage transceivers, is that its AM filter is limited to a width of 4.2 kHZ. When I first learned of this, I thought it would be a deal-killer for me. But I was wrong. The audio sounds much more robust and “wide” than I would ever have guessed. It’s excellent. Want more details? I made an extensive review of the Elecraft KX3 in the SWLing Post.

You can purchase the Elecraft KX3 directly from Elecraft.

Note: Elecraft tech support can instruct you in disabling “transmit” on the KX3, if you wish.

Update: Also check out the KX3’s new sibling, the Elecraft KX2.

The Kenwood TS-590S ($1,500 US)

The TS-590S has an excellent general coverage receiver and brilliant audio fidelity. With one of the lowest noise floors in the business, the 590S is well respected amongst amateur radio operators and shortwave radio listeners. If you doubt this, see how the TS-590S compares on Rob Sherwood’s receiver test data page.

You can purchase the Kenwood TS-590S from Universal Radio or other ham radio equipment retailers.

Updates

[June 13, 2020] Since originally publishing this article, a number of general coverage transceivers have hit the market. Many of them are very affordable.  Here’s a short list of additions:

Looking to spend a little more?

Icom-IC-7600

The Icom IC-7600

If you happen to be a ham looking to upgrade their transceiver for benchmark performance, you may be willing to dedicate more funds to your purchase. My buddy, Dave Zantow (N9EWO), a discriminating reviewer for the late great Passport To World Band Radio, is very pleased using his Icom IC-7600 for broadcast listening. He told me recently, “[The IC-7600 is] not perfect, of course, but does perform near excellent and also has a great display [with] a very useful spectrum scope.” Dave has a full review of the IC-7600 posted on his website.

The Ten-Tec OMNI VII

The Ten-Tec OMNI VII

I have also been impressed with the superb broadcast reception of the Ten-Tec OMNI VII ($2,800 US), Ten-Tec Eagle ($1,800 plus wide AM filter) and Orion series transceivers. While the OMNI VII and Orion II will set you back more than $2,000, used original Orions can be found for $1,800 and even less. Ten-Tec still services all of their radios at their headquarters in Sevierville, Tennessee.

Used transceivers

If you would like to save some money, consider searching the used market for one of the radios mentioned above. Alternatively, look for some of these select transceivers that are no longer in production, but are known to have capable general coverage receivers (do note that what follows is simply a selection, not a comprehensive list):

Keep in mind, when you purchase a quality used radio, you can get excellent value for the performance it will reward you. The flip side of this, though, is that if you purchase a radio that hasn’t been in production for over a decade, the chances of finding replacement parts become more difficult with each passing year.

For more hints on purchasing a used rig, check out our Marketplace page.

With the option wide AM filter installed, the Ten-Tec Eagle makes from an amazing broadcast receiver. They are available new from Ten-Tec, but can also be found used.

Summary

If you plan on investing in a fine communications radio, it may be best to economize by investing in a good general coverage transceiver. For the prospective ham, the leap from a tabletop receiver to a fine general coverage transceiver may be less than $300. To prove my point, if an SWL planning to get a ham ticket asks about buying the venerable Icom R75, I would encourage spending $250 to get the Icom IC-7200, instead.

Indeed, with modern receiver architecture, there is little reason not to invest in a good general coverage receiver that you can also use to communicate all over the world when you get your ham ticket. And, need I add, it’s fantastic fun for the money.

Today: Choppy seas for the Shipping Forecast

Peeters_Sea_storm

Since the dawn of time, there is, there was, and there always has been…the Shipping Forecast. We set our clocks by it. Despite the complexities of our planet–war, famine, daytime television–the Shipping Forecast has been there for us.  Our steady friend amid the choppy seas of life. Our rock of Gibraltar…our security blanket.

Regardless of our diverse beliefs (or unbeliefs), it seems we all believe in the Forecast. We somehow find ourselves regularly returning to its altar, taking comfort in its soothing ministry. And why should we not? It’s been there, without fail, for ninety years.

That is…until this morning.

This morning, BBC Radio 4, who produces the Shipping Forecast experienced some technical difficulties. These, alas, led to a failure to broadcast the Forecast for the first time in, yes, ninety years.  Andy Sennit shares this article from The Guardian:

It was early-morning chaos and warnings of impending armageddon when BBC Radio 4 failed to broadcast the Shipping Forecast for the first time in more than 90 years.

The BBC radio service is something of an institution, metronomically broadcasting four forecasts a day since 1924, a routine which failed for the first time at 5.20am on Friday.

A technical glitch meant the BBC’s World Service was played in its place, a gaffe that prompted listeners to take to Twitter to voice their bewilderment.

Kirsty Connell said: “Eep. The shipping forecast didn’t get broadcast on @BBCRadio4 this morning. Isn’t that the sign of impending nuclear armageddon?”

Jordan Rowland added: “No shipping forecast? If UK submarines don’t get shipping forecast, don’t they launch nuclear attack?”

The BBC was only able to resolve the issue at 5.40am when it cut back to the Radio 4 programme. Friday morning’s Shipping Forecast eventually aired 6.40am.

[Continue reading…]

If this news has greatly unhinged you (as it has me) rest assured:  the world continues. Thus the Forecast will await us at its regularly scheduled time tomorrow morning.

(Readers, thanks for letting me wax poetic.)

Pirate Radio Recordings: Wolverine Radio

SWLing Post reader, Steve Yoth, decoded this Wolverine QSL two weeks ago using a Flex 3000.

A previous eQSL from Wolverine Radio. Try decoding the one at the end of this recording! 

For your listening pleasure: 1 hour, 20 minutes of the pirate radio station, Wolverine Radio–recorded May 26, 2014 starting around 1:20 UTC.

Wolverine was broadcasting on 6,950 kHz in the upper side band. Typical of Wolverine, lots of music variety which spans the decades and no commentary other than station ID throughout.

At the end of this recording, you’ll hear an SSTV QSL card being transmitted.

Try decoding the QSL image from this recording–it’s quite easy! I usually decode Wolverine’s SSTV QSL with Chris Smolinski’s SSTV app for iPhone, but there are other programs to do this. The eQSL above came from a broadcast about two weeks ago and was submitted by SWLing Post reader, Steve Yoth.

An easier way to comment on the SWLing Post

If you’ve ever commented on the SWLing Post (or almost any other website, for that matter), you’ve no doubt been challenged by a CAPTCHA code before your comment could be published. The CAPTCHA system saves this blog from hundreds of bogus comments each day so it’s a necessary tool.

For those of you not familiar, CAPTCHAs look like this:

CAPTCHA-code

While the CAPTCHA code above is relatively simple, many are not and require several attempts before you can prove to CAPTCHA that you’re a human and not a SPAMbot. In this sense, CAPTCHAs can be rather annoying.

How to get around CAPTCHA on the SWLing Post

If you’re a regular here on the SWLing Post and would like to comment without a CAPTCHA moderation, I can register you for a subscriber account on the SWLing Post. I’ve made it so that CAPTCHA will skip any SWLing Post account holder who is logged in at time of comment.

Because of SPAMbots and Malware, I don’t make registration open to the public; I manually create each account.

If you would like an account, simply email me with the following info:

  • Your preferred username (a one word name, callsign, etc.)
  • Your valid email address
  • The make and model of your favorite radio (just a test to make sure you’re human! SPAMbots rarely listen to the shortwaves.)
  • Optional: your personal website URL (if you have a blog, etc.)
  • Optional: your full name (only if you want your name to show with your comments)

I’ll assign you a password which you can change later.

As soon as I create your account, you’ll receive a short email with your username, password and the URL to log in.

You’ll need to be logged in to the SWLing Post to avoid the CAPTCHA code, but I think it’s a much easier and quicker way to comment.

CW pirates promote separatist movement in Ukraine ?

Disputed Ukraine Map via Wikimedia Commons

(Source: Southgate Amateur Radio News)

“Two CW [Morse Code] stations have appeared on the higher HF bands, claiming to operate from Donetsk, as promoting a separatist ‘Peoples’ Republic of Donetsk’, or ‘NovoRossiya New Russia’.

The callsigns, D0A and 1C4M are believed to be two operators on the same transmitter. The callsigns are invalid and do not count for anything in ham radio terms.

While a QSL manager may be appointed shortly in Donetsk, communications are poor, and direct QSL is unlikely to succeed.

There is some doubt that the stations are really in Donetsk. There is evidence that they may be operating from Kazakhstan.”

Many thanks to the Southgate ARC for this news item.

Has anyone logged or recorded these pirates?

Pirate Radio Recordings: Hot Legs Radio (corrected)

"Grandma! Is that Cyndi Lauper buried in the static?"

“Grandma! Is that Cyndi Lauper buried in the static?”

For your listening pleasure: about 20 minutes of pirate radio station, Hot Legs Radio–recorded May 25, 2014 starting around 1:55 UTC.

Hot Legs Radio was broadcasting around 6,925 kHz in AM.

Hot Legs was rather weak and somewhat over-modulated during this broadcast. Indeed, in regular AM mode, I couldn’t make out the station ID at all. Fortunately, by turning on the WinRadio Excalibur‘s AM synchronous detector and selecting the less noisy lower sideband, I dug the signal out of the noise. AM sync also helped compensate for the over-modulation.

You’ll hear me re-tune a couple of times in this recording. Hot Legs’ signal was a bit of a moving target.  I don’t think it would have been as noticeable in standard AM mode (which is more forgiving of drift), but in AM sync, you’ll hear a tone when the frequency shifts.

Still, I’m quite happy to have caught Hot Legs Radio–a new pirate logging! Hope to hear them on again soon.

Update: Correction to station name. I originally posted this as “Hot Raves Radio.” Many thanks to Andy Yoder for the correction!
