I just confirmed with Ten-Tec that the RX-320D PC controlled receiver and the Ten-Tec Superhet receiver kit, the Model 1254, have both been discontinued.  A Ten-Tec representative told me the reason both of these models have been discontinued and removed from Ten-Tec’s product line is because one of the parts used in production is now obsolete.

A long run…

The RX-320 and RX-320D have had a very long product life as the RX-320 was introduced in the late 1990’s (1998, if memory serves)–pretty amazing.

I owned an RX-320D for a long time and thought that it was still a great value. Here’s a review I wrote in 2009.

As third generation SDRs have emerged, and become so affordable in the past few years, it’s hard to justify the purchase of a receiver whose control software was designed for Windows 95.

So long RX-320D, you’ve had a long run…

I have SWLing Post reader, Larry, to thank as his recent inquiry about the Model 1254 Superhet kit prompted me to call Ten-Tec for verification. 

Looking back at the The 26th Annual SWL Winterfest

I originally wrote this article for the July 2013 issue of Monitoring Times Magazine. I hope you enjoy:

Every year, I look forward to the only event I know that brings together both my avid interest in radio and my loyal radio-listening friends: the Winter SWL Fest. This is the one place where, among the 100-plus attendees, you can talk freely about all aspects of the shortwave hobby without any need of explanation as to why you find radio so fascinating. As a result, over the course of the five years I’ve attended the ‘Fest, it has begun to feel less like a technical hobbyists convention and more like a (most enjoyable) family reunion.

Larry Will of Area 51 presents an audio and video history of WBCQ

This year, and for the third year in a row, the Winterfest was held at the DoubleTree Inn and Suites in Plymouth Meeting, Pennsylvania, just outside Philadelphia. The venue is spacious and comfortable, and all presentations are held within its generous environs.

Moreover, we enjoyed presentations on a number of interesting and unique topics that were, by no means, limited just to shortwave radio. A few topics catered to individuals who simply enjoy DXing in any forms. Here’s a sampling:

  • Ed Mauger started the forums off on a light note with a fun discussion on how to increase the size of your radio collection through online auctions and flea markets. His forum drew a large crowd–and many questions.
  • Larry Wills, of Area 51 fame, held the second forum, which was a look back through the WBCQ video and audio archives. During the course of his presentation, Larry covered many of the nuances of WBCQ’s history, including some of the people and circumstances surrounding the birth of this remarkable free speech radio station. Trust me when I say that it was not difficult to keep the audience engaged on this topic: WBCQ listeners are well aware of the variety of shows, not to mention the on-air personalities, that station features. Larry’s presentation put these in context. By the conclusion, I felt I had visited the WBCQ transmitter site in Monticello, Maine, myself.
  • Mario Filippi’s forum, DXing with a Dish, explained the hobby of TV DXing–in a sense, via Free-To-Air (FTA) satellite television and radio. His presentation was comprehensive, covering everything from the components of a home system to the free content currently available–and speaking of satellites, Dave Marthouse’s forum, Sounds from Space: Monitoring and Tracking Satellites Using HF, taught us how to monitor various orbiting satellites that can be heard throughout the spectrum. He also demystified the process, showing us how easy and inexpensive hunting space sounds can be.
  • Skip Arey presented a topic many ham radio operators can appreciate, namely, QRP: How Low Can You Go? Skip’s presentation made for an interesting juxtaposition to the kilowatt shortwave broadcasting world when he revealed how to communicate across the planet on 5 watts or less–!
  • Jef Eichner once again presented on the topic of loop antennas. As more and more of us are bombarded with radio interference (RFI) from consumer electronics, loop antennas make for an affordable means to an antenna that can help you cope with noise. Though this topic can get pretty technical, Jef kept the discussion at a level most anyone could understand. He even brought his own homemade loop for demonstration.
  • Dr. Kim Andrew Elliott and yours truly presented a forum on Digital Text via Shortwave Broadcast. We demonstrated how incredibly effective and simple it is to broadcast digital text modes used by radio amateurs (e.g., PSK31) on analog amplitude-modulated shortwave broadcasts. These modes can be decoded by anyone with a basic shortwave radio and and personal computer or smartphone. We proved that even when the human voice is difficult to comprehend because of poor shortwave reception conditions, digital text can be received with nearly 100% accuracy. The applications for this technology are numerous, but the service can be invaluable when the internet is disrupted by disasters (or by dictators). [Update: since publishing this article, Kim Elliott’s VOA Radiogram has enjoyed great success on the air.]
David Goren hosts the annual Shortwave Shindig

Of course, there are a few mainstays in the Winterfest forum line-up, forums we’ve come to anticipate:

  • The annual “Scanner Scum” forum, which this year focused on scanner antennas that are effective and affordable. The presenters also explained the differences in the numerous types of rechargeable batteries on the market; as a result, many of us now have a better understanding of discharge curves and their effect on radios.
  • The Annual Pirate Forum always attracts a large crowd. This year, George Zeller and a panel of pirate broadcast enthusiasts took the stage to introduce newcomers to the pirate radio listening hobby and review the pirate radio year. This year, Free Radio Weekly editor Chris Lobdell and the pirate station Captain Morgan were inducted into the Pirate Radio Hall of Fame.
  • David Goren (our resident Shortwaveologist) held his 10th Annual Shortwave Shindig, an evening celebrating the unique sonic properties of our favorite international medium. David showcased a number of his own shortwave audio productions and numerous intriguing recordings. Saul Brady played radio-themed folk music, and the talented Martin Peck quizzed the audience with his woodwind renditions of dozens of interval signals past and present. Martin even took requests from the audience and played interval signals on demand…Where else could you hear this stuff, but at the Shortwave Shindig of the Winter SWL Fest?

Of course, there are also opportunities to buy and trade equipment at the Friday night swap meet–and if you’re lucky, you might just win a treasure in the silent auction (where all proceeds go to charity) or in the dinner banquet raffle. Indeed, since I’ve been going to the ‘Fest, I’ve been most impressed with the number and quality of items in the raffle. The odds are good, and this year yours truly even won a few items. This year’s grand prize? The newly introduced CommRadio CR-1 tabletop SDR.

Winterfest-SocialAs interesting and varied as the forums are, and as rewarding as the silent auction and dinner/raffle can be, I believe many of the ‘Festers would agree that one of the strongest attractions is the yearly opportunity to socialize and connect with all of radio’s kindred. At times radio listening can feel like a very solitary hobby, as voices drift in and out of the ether; perhaps the beauty of the Winter SWL Fest is that it brings everyone together face-to-face to socialize and to theorize on the ever-widening scope of radio communications and broadcasting.

Many thanks to Festmeisters John Figliozzi and Richard Cuff

In short, the SWLing Winterfest is always a unique and dynamic event–but don’t take my word for it. Next year, you might just want to check it out for yourself! It will be held February 28-March 1st, 2014 somewhere in the greater Philadelphia area.

Cameroon takes a note from Mugabe, shuts down 11 media outlets

While I certainly can’t confirm they got the idea from Robert Mugabe, nonetheless, it seems more than coincidental that as Cameroon enters an election cycle, the government is closing down media outlets that journalists describe as critical of the current government.

(Source: VOA via Andy Sennitt)

Cameroon’s National Communications Council has closed down 11 newspapers, television and radio stations, for what it describes as disrespect of ethics and professional norms. But journalists say these private media outlets are being silenced because they are critical of the government.

On Friday morning, Cameroon’s state radio CRTV announced the suspension of three radio stations, a television station and seven newspapers.  The report said Cameroon’s National Communications Council also suspended a journalist and two publishers.

The journalists and media organs were accused of failing to respect professional norms and ethics. But Ngah Christian Mpipgo, publisher of the Guardian Post— one of the suspended newspapers — called the act an abuse of press freedom.

“I mean, I look at it as some kind of repression,” he said. “It is understood that the Guardian Post is too critical of government action, and then coming at a time when we are preparing for elections, I have to just conclude that it is a way of stopping us from exposing a well-planned government rigging machinery,” said Ngah.

The publisher said the law stated publishers should be informed and warned before any government sanctions were meted out.  But that was never done.

“We have never received a warning,” he said.

However, some journalists said the Communications Council had called on media practitioners to be more professional, but the calls were largely ignored.

Simon Lyonga, president of the Yaounde chapter of the Cameroon Association of English-Speaking Journalists, said that many of those working in Cameroon’s media industry were, in his word, quacks.

“We are in a profession where anybody comes in, they usually do not know the ethics of the profession and so go against it.  So I think if somebody is sanctioned for not respecting the ethics of the profession, to me [that] is not press censorship,” said Lyonga.

Some media outlets in Cameroon have published articles warning of alleged actions by the government to rig upcoming municipal and council elections in favor of the ruling party, Cameroon People’s Democratic Movement.

Kilian Ngalla, a journalist who has been closely observing these developments, said the closure of the media outfits could be interpreted as an initiative to silence critical voices.

“At a time elections are coming, it is curious that the government chooses this time to start banning press organs.  When you look at the composition of the National Communication Council, the president there is appointed by the president of the republic. And that director is executing the opinion of the head of state.  I think they are actually gagging the press,” he said.

The suspension order said that except for one radio station, the media outlets may be re-opened next month – after the September 30 elections.

KVOH test broadcasts this weekend

KVOHCoverage-Map-VoiceOfHopeRay Robinson, Operations Manager at KVOH (Voice of Hope / Voz de Esperanza) writes:

[W]e would very much appreciate your reception reports (or preferably, recordings) of the tests we will be running on 9975 kHz on Friday and Saturday evenings this week. The exact times are:

  • Saturday 7th – 0100-0400 UTC
  • Sunday 8th  – 0100-0400 UTC

In North and Central America, that would be this Friday and Saturday evenings, 8-11pm Central, 9pm-12am Eastern. The test program will be similar to last time, but not exactly the same. It will contain segments in both English and Spanish.

The transmitter site is near Los Angeles, and here it is currently getting dark at about 0230 UTC (7:30pm local). Therefore, during the first half of these tests, the transmission path will be increasingly in darkness, and for the last 90 minutes or so will be in complete darkness. Please let us know what reception sounds like at your location as the evening progresses, and also what type of receiver and antenna you are using.

Reception reports may be emailed to “[email protected]” or sent to:

KVOH – Voice of Hope
P.O.Box 102
Los Angeles, CA 90078
United States of America

All correct reports will be verified with our QSL card.

Thank you very much in advance for your assistance with this test!

VOA Radiogram, 7-8 September 2013: Fldigi, Flmsg, Flamp, RSIDs, MFSK

VOARadioGram(Source: VOA Radiogram)

VOA Radiogram for the weekend of 7-8 September 2013 will include more experiments with RSIDs, the brief signals that automatically switch your decoding software to the correct mode.

For best results, please install Fldigi 3.21.75 from w1hkj.com. When you have 3.21.75 installed, go to Configure > ID > RsID, and adjust Errors to 0 (zero). This will prevent Fldigi from flipping to another mode while decoding our MFSK transmissions. For more information about this, seewww.w1hkj.com/FldigiHelp-3.21/ConfigID.html

Please also download the latest versions of Flmsg and Flamp (2.1.00) from w1hkj.com.

This weekend’s VOA Radiogram will include another transmission in MFSK128. This will be done mainly to see if the RSID works. However, to improve the chances for a successful decode of the very fast MFSK128, it will be in Flamp format. A paragraph will be divided into seven blocks of 64 characters each. And it will be transmitted three times, with the second and third passes filling in any blocks with incorrect checksums. Make sure Flamp is running before the MFSK128 transmission begins; it does not turn on automatically like Flmsg.

The foreign language for the weekend will be Spanish, with brief VOA news items in both plain text and Flmsg formatted. Please turn off and restart Fldigi before each of this weekend’s VOA Radiogram broadcasts to ensure the accented Spanish letters display correctly. You will need the UTF-8 character set. The adjustment can be found via Configure > Colors & Fonts.

In the Flmsg-formatted Spanish news story, you will see several html codes such as í for the accented characters. They might look like decoding errors, but the story should look OK when the web page renders.

To make Flmsg work with Fldigi, in Fldigi: Configure > Misc > NBEMS — Under Reception of flmsg files, check both boxes, and under that indicate where your Flmsg.exe file is located.

Here is the lineup for VOA Radiogram, 7-8 September 2013:

Shortwave Radio Recordings: Voice of Greece

greeceLately, the Voice of Greece has been playing very long sets of music; and not all of it Greek. I assume the break in format has to do with the reorganization of Greek national broadcasting.

I believe VoG could be cut without notice. With heavy budget cuts being dealt to national broadcasting, I doubt investment in shortwave radio will continue since they no longer even have an English language service. This is one of the reasons I’ve devoted a lot of recording time to VoG as of late. Admittedly, I certainly hope I’m wrong about my prediction.

On September 1st, I recorded over five hours of VoG, starting around 22:00 UTC. After about an hour of Greek commentary, you’ll hear music ranging from contemporary to classical.
