Cold War Broadcasting: Two articles feature RFE & Radio Liberty

Many thanks to SWLing Post contributor, Andrea Borgnino, who shares the following article from the website Journalism Is Not A Crime:

From Propaganda to Journalism: How Radio Free Europe Pierced the Iron Curtain

The end of the Second World War signaled the beginning of an information war in Europe. As the military alliance between the Soviet Union and its main western allies — the United States and Britain — came to an end, the USSR backed small communist parties that asserted ever-tighter control over much of Eastern Europe.

Speaking in Fulton, Missouri in March 1946, former British Prime Minister Winston Churchill warned of an “Iron Curtain” of totalitarian control sealing off half the continent. His speech heralded the beginning of an ideological “cold war” that would last for more than 40 years, a struggle in which citizens of the eastern camp were only meant to hear one side of the argument.

“We talk about the Iron Curtain as a physical barrier, but it was also an information curtain,” says A. Ross Johnson, a former director of Radio Free Europe and author of a history of RFE and its companion station, Radio Liberty, which broadcast into the Soviet Union. “All the communist regimes saw control of information as a key to their rule.”

An SWLing Post contributor also recently shared the following PDF article by A. Ross Johnson for the Wilson Center. Here’s the summary:

To Monitor and be Monitored– Radio Free Europe and Radio Liberty during the Cold War

Monitoring of Soviet bloc radios was an important input to Radio Free and Radio Liberty broadcasts during the Cold War. RFE and RL also monitored the official print media and interviewed refugees and travelers. Soviet bloc officials in turn monitored RFE, RL, and other Western broadcasts (while jamming their transmissions) to inform themselves and to counter what they viewed as “ideological subversion.” On both sides, monitoring informed media policy.

RFE and RL monitored their radio audiences through listener letters and extensive travel
surveys, while the Communist authorities monitored those audiences through secret police
informants and secret internal polling. Both approaches were second-best efforts at survey
research but in retrospect provided reasonably accurate indicators of the audience for RFE, RL, and other Western broadcasters.

Video: Air traffic on the HF bands

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

Air traffic bands on VHF is well-known.

Not so well-known are the shortwave (HF) communications networks that must be operated by transoceanic flights.

This is an ARINC station for San Francisco, California. I am located about 70 miles inland from this station. I assume ARINC is using a directional antenna system beamed westward toward the Pacific Ocean.

I recorded this video of an ARINC station late last night for my YouTube channel.

Many thanks, Dan!

I enjoy monitoring air traffic on VHF and often forget that when I’m outside the range of an airport’s tower, I can still hop on HF and often hear international traffic. Thanks again!

Radios spotted in the Netflix movie “Spectral”

Last week, I watched the Netflix movie, Spectral, and couldn’t help but notice a couple of radios on set.

I spotted the first rig at the beginning of the film while the camera was panning a military communications center. It’s a dark screen shot, but I believe this may be a Kenwood TS-940S:

The second radio appeared to be a 1950s-60s era Grundig tabletop. Perhaps someone can identify the model?

I’ve noticed that many of the radios we’ve spotted in film and TV lately have been in Netflix original productions. I assume the art/set designers appreciate the radio aesthetic. I certainly do!

Senate Hearing: ABC & HF broadcasting

First thing I tuned to with my Elecraft KX2 in August 2016 was Radio Australia on 9,580 kHz. Radio Australia is no longer on shortwave.

Many thanks to SWLing Post contributor, Nigel Holmes, who shares the following link to the ABC & HF broadcasting Senate Hearing and notes:

http://parlview.aph.gov.au/mediaPlayer.php?videoID=355749

3 hours in total.

Three quality options for streaming/download – Hi 1400 MB, Med 675 MB & Lo 250MB

Witnesses in order
1. DFAT (Foreign Affairs & Trade)
2. 52′ Gary Baker (ex-Broadcast Australia) and NH (ex-ABC/RA)
3. ABC
4. 2h22′ Graeme Dobell (ex-ABC/RA journalist & ABC Pacific correspondent) (By far the most interesting testimony, a tutorial in South Pacific geopolitics. Who knew the Australian Constitution refers to the S Pac in the External Affairs Powers area??!!)

I was tickled by Sen. Xenophon’s retort, “What, they don’t have ears?!” to ABCs assertion that letters of support (for HF b’casting) from the hobbyist fraternity were irrelevant. Sen. Xenophon could have added, “What, they don’t vote, pay taxes or are entitled to have a view of ABC?!”

A couple of you had trouble locating the submissions to the enquiry, they’re found here:

Many thanks, Nigel, for sharing this and for your regular updates from the Senate.

Catch the 2017 BBC Antarctic Midwinter Broadcast?

Listening to the 2017 BBC Antarctic Midwinter Broadcast from the back of my vehicle in Saint-Anne-de-Beaupré, Québec, Canada.

Yesterday afternoon, I packed up the Sony ICF-SW100, Audiomax SRW-710S and Elecraft KX2 portables in search of a quite spot to listen to the BBC World Service Antarctic Midwinter Broadcast. I also packed my PK Loop and NASA PA 30 antennas.

I’m traveling in Canada again and staying in an RFI-dense condo. There was no way I’d hear the broadcast through the noise, so I searched for a field location.

I discovered a quiet spot to park on the banks of the Saint Lawrence River in Sainte-Anne-de-Beaupré, Québec, Canada.

The location was almost ideal: it was RFI quiet compared to other spots I checked and I had access to a tree where I could hang the NASA PA 30 wire antenna.

Once I arrived, with little time to spare, I deployed the NASA PA 30 and connected it to my Elecraft KX2 transceiver. I then connected the Sony ICF-SW100 to the PK Loop antenna.

Since the KX2 is the most sensitive receiver in my travel arsenal–and even has built-in noise blanking, variable DSP noise reduction, and variable filter width–I used it as the source for my recording.

I checked audio levels by tuning the KX2 to the Voice of Greece on 9420–VOG was blowtorch strength.

None of the frequencies used for the Midwinter broadcast were ideal for my location and time of day (after all, these broadcasts target Antarctica!) but last year I did successfully receive the 41 meter band broadcast.

My fingers were crossed as the broadcast time approached (17:30 local/21:30 UTC).

A few seconds before the half hour, I heard the AM carrier light up on 7,360 kHz (ASCENSION). Very good sign! The broadcast audio followed a few seconds later and was weak, but intelligible. I would give the signal an overall SINPO of 35343.

I couldn’t receive a thing on the 6035 kHz (DHABAYYA) and only an extremely faint signal on 5985 kHz (WOOFFERTON).

The Elecraft KX2/NASA PA 30 combo did prove to be the most effective receiver/antenna pair.

I forgot to do two things in advance, however: to turn off the KX2’s key beeps (which would have been audible in the recording had I adjusted receiver settings) and to set my Zoom H2N to record in WAV format. Oh well…

I was very pleased with the results, all things considered.

The Sony ICF-SW100/PK Loop combo was also quite effective. The signal was a little weaker and less stable than the KX2, but I was still very pleased overall. Here’s a short video–note that I have the sync lock engaged:

The PK Loop was positioned on a folding trail seat close to the ground. After experimenting, I found that loop height had little impact on overall reception, so I opted to keep it closer for accessibility.

The PK Loop antenna.

Very impressive reception of weak DX for such a small portable a compact loop antenna. In the end, the SW100 is a phenomenal little DX machine!

I brought the Audiomax SRW-710S along as well. Since it has a built-in digital recording feature, I had hoped it might provide an additional recording of the broadcast.

Sadly, it fell short.

No matter how I positioned the receiver, nor what antenna it was connected to, the SRW-710S simply couldn’t cope with the weak signal, QRN and overall band conditions. The noise floor was high and the signal (when audible) very unstable. It was like listening to a battle between the receiver’s internal noise and the target signal.

The $20 Audiomax simply can’t compare to benchmark receivers like the ICF-SW100 and Elecraft KX2. Still, it’s an acceptable little radio for recording stronger shortwave, mediumwave and FM signals. I completely agree with Troy Riedel’s assessment.

Another Midwinter broadcast for the books!

It’s always a treat to enjoy the BBC Antarctic Midwinter Broadcast live, knowing that the BAS crew, wintering over in Antarctica, are enjoying it at the same time!

That, in a nutshell, is the magic of shortwave radio.

Please share your recordings!

I’ve already received a healthy number of recordings from SWLing Post readers!  Thank you so much!

If you have a recording of the 2017 Midwinter Broadcast that you’d like to submit, please do so by Sunday. I’m participating in Field Day and attending an airshow this weekend, but plan to publish a post with all of the recordings and your photos early next week.

Please send your recordings with any notes and photos to my email address which can be found on the Contact page. If you submit a video, please upload it to YouTube or Vimeo and simply send me the link. Thank you!

eBay: Galaxy R-530 Communications Receiver & Speaker

Many thanks to SWLing Post contributor, Rob G, who shares a link to this rare Galaxy R-530 receiver and speaker on eBay:

Click here to view on eBay.

The R-530 is certainly a handsome receiver. FYI: the last time we posted one of these from eBay, the final price was $470 shipped, but this particular listing also includes the SC-530 matching speaker.

Earlier this year, when an R-530 appeared on eBay, our resident rare receiver guru, Dan Robinson, chimed in with the following:

Some observations on this. The R-530, and military version R-1530, were considered fairly top of the line when they were made. They’re still among the rarer radios on the used market, though not the rarest. The R-1530 is not seen often.

On performance, these receivers were not on the same level as National HRO-500s, 51Js, and R-390s. This was made by Hy-Gain after all, which was not top of the heap in receiving design.

However, the R-530/1530s are great looking pieces. Anyone considering these should make absolutely sure that the PLL circuit functions on all bands. Poor cosmetic condition is a tipoff that the radio had a hard life.

Are there any Post readers own and use an R-530 of R-1530? Please comment!
