How VOA’s Communications World Started

How VOA’s Communications World Started

by Dan Robinson

NOTE: This exclusive is being published simultaneously with the North American Shortwave Association (NASWA) journal in its March 2022 edition.

Voice of America recently observed its 80th birthday. Readers may recall that in the mid-1980’s into the 2000s, VOA broadcast a program about communications, but which was in fact designed specifically for shortwave listeners.

Communications World as it was known owed its existence to my efforts in the late 1970’s and into the early 1980’s to persuade VOA managers to put such a program on the air, The story is told in detail here for the first time.

In a SWL career that began in the late 1960’s, I was an enthusiastic consumer of DX programs broadcast by stations at the time, from Radio Netherlands to HCJB and others. I always wondered why VOA wasn’t among them, and I was determined to make some progress on this.

First steps came in 1975 as I was attending The American University and began making contacts at VOA in downtown Washington, DC. This would become a multi-year effort to induce VOA to re-start a DX’ing program. I say “re-start” because I would later learn that VOA once had such a program, but aimed at radio amateurs.

These early efforts included at one point a meeting with the head of a major think tank on K Street in Washington. I can only imagine their reaction when two college age kids (I was accompanied by ace DX’er Taylor “Pitt” McNeil) arrived seeking help in selling a federal agency on a hobbyist show.

I never learned whether anything came from that meeting. In my final two college years, I interned with ABC News, where I observed network operations, including the evening news with Frank Reynolds, and also interned with local station WASH-FM.

By 1979, my contacts at VOA had led me to part-time work in its English to Africa, Worldwide English, and central news divisions. In 1980, I was formally sworn in as a full-time VOA news writer. My objective was to become a VOA foreign correspondent, which I would achieve in 1983. But putting VOA back on the board, so to speak, with a SWL program remained high on my priority list.

A pilot for the show needed to be produced. It needed a name. What came to mind was something containing the word communications, to have wider appeal. So, there it was: the VOA Communications Magazine.

My time in VOA’s central news operation included work on all three shifts over 24 hours. On the side, I set about putting together a script for VOA Communications Magazine – conceptualizing what elements would go into it. By 1983 – just before I departed for Nairobi as VOA’s new East Africa correspondent – we were ready to record the pilot.

The show began by recognizing World Communications Year, and a message noting that we would cover SW hobby news, international broadcasting developments, satellites and computers, news about receivers and antennas, along with letters from listeners.

WRNO New Orleans had gone on the air on shortwave. I thought that would make an interesting segment. Shortwave broadcasting had not yet started its downward slide. Stations remained on the air in Africa, Latin America, and Asia. Transmitter manufacturers still had customers. New stations were coming on air.

I served as host of the Communications Magazine pilot. Bob Arnold, who was doing science reporting for VOA at the time, voiced a roundup of broadcasting news. Included were some of my personal recordings, including Voice of Kenya and Radio Mozambique.

In the news, Kenya was reported planning international broadcasting (we now know this never happened). Ghana was expanding domestic radio. The U.S. was helping Liberia expand rural radio. We noted ELBC and ELWA, and played a recording of ELWA.

Iran was installing what were expected to be the world’s most powerful transmitters. There was news from Singapore, and a recording of Radio Singapore. Malaysia planned two 500 kw transmitters. I noted existing domestic Malaysian stations, and included a recording of Radio Malaysia Sarawak.

Arnold reported on the explosion of the production, distribution and storage of information, including an interview with Wilson Dizard, then with Georgetown University.

Dipping into the mailbag I read letters and reception reports from VOA listeners in Denmark, Sweden (one of whom used a Grundig 3400 receiver), Australia (who used a Panasonic RF-2800), and Japan (who used a Kenwood R-1000).

My interview with Joseph Costello of WRNO concluded the pilot, and began with a recording I had made of a WRNO test transmission. Costello pointed to “a couple of thousand pieces of mail per month,” and surprising response from New Zealand and Australia, though WRNO’s signal was beamed northward.

Private shortwave stations were granted to reflect the culture and lifestyle of the United States, Costello said. By partially simulcasting WRNO-FM, listeners heard about life in New Orleans, with coverage of the Jazz and Heritage Festival, and progress reports on Mardi Gras. WRNO was considering a morning Spanish service beamed to central and south America

Doug Flodin of Drake-Chenault discussed the purpose of KYOI. And we reported on other shortwave broadcasters preparing to go to air, including Radio Miami International, and KNLS from Alaska.

Based on my pilot for VOA Communications Magazine, VOA green lighted what would become Communications World, hosted first by Gene Reich, who later would join Worldspace, the satellite radio pioneer that filed for bankruptcy in 2008, and later by Kim Elliott.

This is the first time I have told the in depth story of how Communications World came into being, which likely never would have existed had it not been for my efforts to bring this kind of program to Voice of America. The full 1983 pilot for Communications World is available on the Internet Archive and below:

eBay Find: A “near mint” Sony ICF-6000W PSB/FM/AM band receiver

Many thanks to SWLing Post contributor, Dan Robinson, who shares a link to this Sony ICF-6000W he found on eBay:


The seller notes that the condition is “near mint” and the radio works perfectly both electronically and mechanically.

I absolutely love the design of this radio. When this was being produced (assuming sometime in the 1980s), Sony and Panasonic’s aesthetic smacked of utility, simplicity, and had a near military-grade feel. Ever function had a switch or knob.

Neither Dan nor I have ever seen this particular model before. If I had money to burn, I’d buy it in a heartbeat. Sony radios of this era tended to have stellar AM/MW performance. I’d love to see how large the ferrite antenna inside might be.

Note that even though this radio may work perfectly–it’s obviously been very well taken care of–you would need to mentally allot funds to have it re-capped at some point soon (Vlado could do this, I’m sure). You wouldn’t want a leaky cap to damage the board or other components inside. With radios pushing 40 years old, you must plan to replace the capacitors.

The price is $399 US with a modest shipping fee. The seller has stellar ratings and there’s a 30 day return window .

If you own or have owned an ICF-6000W, we’d love to hear your thoughts about its performance! Please comment!

eBay find: A Sony PRO-80 receiver, new in unopened box

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

With still days to go before auction end, this Sony PRO-80 receiver is already above $700 U.S. This is new in unopened box, which explains the sharp price rise.

The seller notes that the unit up for auction has never been opened. The photos of the ICF-PRO80 interior in the auction come from one of their previous listings.

The PRO-80 was one of Sony’s technology showcase receivers, designed in the walkie talkie format. The radios are almost never seen NIB, but aging capacitors often cause audio problems and the tops mounted potentiometers often need cleaning or replacing.

I fully expect this PRO-80 to top $1,000 but the auction winner will have to be prepared for some refurbishing.

https://ebay.us/xgTHGu

Thank you, Dan! I always wanted an ICF-PRO80, but could never afford one back in the day. You’ve got a great point that the winner of this bid may have to re-cap it almost immediately. They’ll need Vlado on speed dial!  It will be interesting to see the price this auction fetches.

Dan compares the Chameleon CHA RXL to the Wellbrook and W6LVP Loops

Many thanks to SWLing Post contributor, Dan Robinson, for the following guest post and review:


Chameleon CHA-RXL:  Is This Pro-level Loop A Worthy Competitor To Wellbrook and W6LVP?

by Dan Robinson

At the end of summer 2021, I took up an offer from Chameleon to test and review their CHA – RXL loop antenna.  The company describes this as a “new design high-performance” LF, MF, and HF receive-only loop perfect for mobile RV and apartment situations and with low noise characteristics.

This is not a cheap antenna, like the Chinese-made MLA-30, but a heavy duty professionally-built unit designed to, as the old TIMEX watch commercial said, “take a licking and keep on ticking”.

Price for the CHA RXL is around $500, though the company dropped the price at to $382 – but only for the two section loop rather than the single piece antenna advertised on its site.

You can see the Chameleon on the company’s website here, but it’s also sold by Gigaparts, DX Engineering and other radio suppliers.  Chameleon lists features as:

Highly directional, balanced input preamplifier to eliminate environmental noise and ground loops, receives on new 2200m and 630m ham bands, flexible mounting and power options, and a stealthy [36 inch] Navy gray loop [that] fades into the background sky.

The built-in preamplifier, says Chameleon, “will enable clearer reception than many large horizontal wire or vertical antennas.”  Weight of the amplifier is given as 7 lbs.  The large pre-amp box is made of heavy metal, with a rubber gasket seal. Continue reading

Dan spots “an ultra rare” JRC NRD-302A at auction on Buyee

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

The seemingly un-ending stream of classic premium receivers continues at the Japan auction site known as “Buyee”:

This ultra-rare Japan Radio Company NRD-302A is expected to exceed the U.S. $5,000 mark.

As premium receiver collectors/users know, the 302A is certainly among the top rarest of the JRC professional/marine line. At the top of that line was the NRD-630, which was described by the company at the time it was being manufactured, as a “training” receiver. For some reason, though more of them were manufactured by JRC, the 302A is even more infrequently seen on the used market.

Listed as “typically unavailable” on Page 347 of the Osterman Receivers Past and Present guide, the 302A exceeds the previous 301A model in having ISB mode and a narrow 0.5 filter, with 1 Hertz tuning resolution. Previous other ultra-rare JRC sets on the Japan site included two NRD-95 receivers, both of which came in at over $5,000 U.S.

What a beautiful radio!  Thanks for sharing this insight with us, Dan. Very curious what this ultra rare rig will fetch!

Dan reviews the CountyComm GP7/SSB (Gen 4)

Many thanks to SWLing Post contributor, Dan Robinson, for the following guest post and review:


CountyComm GP7 / Tecsun PL-368:  Is It All You Need?

by Dan Robinson

It’s been a long wait, but CountyComm, that supplier of all kinds of neat and useful stuff, finally released the GP7 SSB (Gen 4).

As the name states this is the 4th generation of the series of radios adapted by the company from the Tecsun PL-36xxx series of receivers (there was at one point a GP6 that was a never-released special project).

All photos by CountyComm

This walkie-talkie style, though receive-only, portable has undoubtedly been a big seller for CountyComm since the first model came out.  It’s popular not only with SWLs and amateur operators but also with preppers.

When OEM Tecsun finally did what everyone was clamoring for – redesign the radio with a keypad and including features associated with the PL-880/330/990x/501x receivers – the ground shook. Continue reading
