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

While DRM (Digital Radio Mondiale) has long been pronounced DOA (dead on arrival), All India Radio seems to be taking it pretty seriously. Here’s a screenshot of not one, but two simultaneous feeds going out over the same 10 kHz wide 40 meter frequency (7,550 kHz) at 2027 UTC today. The signal on my Perseus was just a tad under S9+5db using my ham band Alpha Delta DX-CC antenna.

image001So what’s the twist, aside from the 2 feeds on 1 frequency? Even at +5 over S9, the feed was only strong enough to occasionally flutter in with some decoded audio. Mostly, it was silence.

[I had] about a 98% successful decode by 2051 UTC when the signal rose to S9+10 db. I could switch between streams by clicking channel button within Dream!

Dan wrote the message above yesterday, I asked him if he could record AIR  today and he kindly sent the following:

AIR DRM recorded today with announcements @ 1930 UTC. Some dropouts as a
great example of the dropout/echo effect heard on DRM when signals are quite
strong enough. This decode was done at S9 signal strength.

Dan actually calls the DRM dropouts, the Max Headroom Effect.”  That is the best description I’ve ever heard, Dan.  Thanks for sharing your notes and recording!

DXing on the Road in Colombia with Don Moore

Radio Mil Cuarenta's studio in Popayan, Colombia. (studio with station's car in front)

Noted DXer and South American radio enthusiast Don Moore (USA) is travelling again and posting fascinating photos & commentary of DXing and life in Colombia.

Don mentions:

The focus is MW. My postings include photos and local recordings of stations from southernmost Colombia including the cities of Pasto and Popayan.  I’m currently in Cali (the third largest city) for two weeks. I’ll also get a complete band scan completed in the next few days.

His current journal entries, photos, and DX clips are on his web site.The Todelar network building in Pasto.

Be sure and check out Don’s extensive coverage of the Central and South American radio scene, and coverage of his previous travels at http://www.pateplumaradio.com

Sean’s recording of an International Space Station EVA

ISSSean Gilbert, WRTH’s International Editor, recently shared this audio he originally recorded on June 19, 2014. Sean writes:

With all the interest in space and the ISS at the moment, I thought I would share a recording I made on 19 June 2014 @ 1715 UTC. This is from the Russian part of the ISS and the audio (which is in Russian) is of the cosmonauts talking during a spacewalk (EVA as they are known). The person speaking is actually in space, outside of the ISS. The audio begins about 2 mins into the recording and lasts for about 5 mins.

[Listen via the embedded player below, or click here for the MP3 version.]

[…]This was received on 143.625MHz NFM (+/- a few kHz due to doppler shift). Receiver here was a Funcube Dongle Pro + into a 2 element circular polarised turnstile in the attic. Signal was lost at a distance of 2000km (to the East of my location in IO92ma) at 3 degree elevation. Altitude of ISS was 418km above earth.

The image [above] shows a grab of the signal, exhibiting doppler shift due to the ISS orbit in relation to the earth.

 […]I would be interested to know what they are saying. […]To me this was far more exciting than receiving SSTV pictures from the ISS. I may never hear another EVA – I am just thankful that I found this as it was an announced/schedules EVA.

That is very cool, indeed, Sean! At some point, I must make an effort to venture up to the VHF neighborhood and attempt to hear the ISS.

I hope there’s a Russophone reader out there who can help Sean interpret the EVA dialog! Please comment!

Star Wars sound designer is, indeed, a radio enthusiast

StarWars-LogoSWLing Post readers may remember a post I recently published in which I believed I’d identified a familiar shortwave time signal station in the Battle of Hoth scene from The Empire Strikes Back. If you haven’t read this post, feel free to do so and listen to the embedded video/audio clips.

Upon hearing this, I went so far as to muse that the Star Wars sound designer might be a radio listener. I asked our readers if anyone could confirm this–?

Well, we’ve got our answer!  I’m truly indebted to an SWLing Post reader who passed my post along to his friend, Ben, who could provide this definitive response:

“This is Ben Burtt, sound designer of the Star Wars films. A friend sent me a link to this blog thinking I would like to comment.

Ben and old recorders

Ben Burtt with his recording gear, circa 1980. The mike on the stand at Ben’s feet is one from his grandfather’s ham radio station in the 1950s, or possibly earlier.

“The answer is yes, I have always been a ham radio enthusiast.”

 

“My grandfather, Harold Burtt, operated W8CD out of his home in Columbus, Ohio 1930s-1960s. I was enthralled as a kid listening to the sounds on his receiver. I heard alien worlds and cosmic ‘voices.’

“So not only did I record his radio, but continued to do so on the Star Wars series and Star Trek as well.

My memory of the Hoth transmission was that it was WWV but it could have been CHU since I was recording all that interested me on the dial.”

Terrific! Thank you, Ben, for taking the time to respond. As I said, you’ve certainly started off this radio enthusiast’s year on the right wavelength…no doubt some of our readers will agree.

Indeed, the powerful sonic experience of the Star Wars and Star Trek films has, in my estimation, helped shape many of us into the radio/sound enthusiasts we’ve become–myself certainly included. Thank you, Ben, for this!  You’ve sharpened my ear to a greater appreciation of sound, especially filmic sound, and your work in particular.    

For readers who are less familiar with Ben Burtt’s work, check out his Wikipedia page and IMDB profile–you’ll find he’s been the sound designer on numerous influential films including the recently released Star Wars: The Force Awakens.

A special thanks to Ben Burtt for sharing these wonderful photos and kindly giving me permission to use them here on the SWLing Post.  I must say, considering my love of radio in the thirties, I especially like that photo of Harold Burtt (W8CD) in his shack.

Jonathan shares archived Media Network Christmas and New Year shows

Crosley-Dial

Many thanks to SWLing Post contributor, Jonathan Marks, who shares the following from his Media Network Vintage Vault.

Jonathan writes:

“Picking up on the idea of revisiting archive Christmas and New Year shows, here are some from Radio Netherlands for the SWL Blog.

Seasons Greetings, Jonathan”

Media Network 26.12.1996 Boxing Day Show

A radio Christmas spent in the Media Network studio way back in 1996. Sounds like we were having fun! I look back on this period as perhaps one of the golden years for Dutch external broadcasting, producing a range of documentary productions in English and Spanish and recording great concerts, both classical and jazz.

This programme focussed on answering listeners’ letters on subjects like satellite television in Australia (DW was organising a bouquet of signals) and the major changes to the commercial radio scene in New Zealand. The auction of FM frequencies in the Netherlands and shortwave stations that sold radios were also topics for discussions. RBI archives have, for the most part, been destroyed. Swiss shortwave listeners were quizzed on their listening habits. The 410 ft tower formerly used by AFN has been dynamited out of existence. Capital Radio in South Africa is in trouble.

MN.28.12.1995 Rhodesia – Answering Back From Francistown

I met the late Harold Robin a couple of times at his home in Tunbridge Wells, UK. He was a brilliant Foreign Office engineer who built the wartime Aspidistra transmitter famous for its clandestine work out of Crowborough. Have a listen to the programmes Wartime Deception and you’ll see what I mean.

Although his work during the war is well documented in books like “The Black Game”by Ellic Howe, I think we managed to capture the other stories from later in his life. For instance, how he invented the “Picolo” modulation system as used by the diplomatic service to communicate text over shortwave between embassies. He also built the BBC Overseas relay station in Oman, and the external service of UAE Radio from Dubai. This edition, recorded after Christmas in 1995, looked at the story of the British response to the declaration of independence by Ian Smith in, what was then, Rhodesia. Harold talks about setting up a mediumwave transmitter in a matter of weeks in the town of Francistown, in the Bechuanaland Protectorate, now called Botswana. Thanks also to Colin Miller for some of the recordings of the RBC. It seems that one of the two transmitters was sent to Cyprus after the World and Rhodesia operation ended, the other ended up in Ordfordness for some experiments on 648 kHz. You might also want to check out the video of Margaret Howard, who refers to a special programme transmitted over this MW sender. It was called the World and Rhodesia and was more of a UK government editorial than any programme the BBC would make. The programme concept didn’t work although it seemed to have taken the British government a couple of years to find out. Harold refers to staying in the Tati Hotel River Lodge, about 8 kms outside of Francistown. Sure enough, it’s still there.

MN.23.12.1982: Christmas Review 33 years ago

I picked this recording out of the archives because it has a nice capsule summary of the major media stories from 1982. The highlight was, of course, the Falklands-Malvinas “conflict”. This programme contains clips from the FIBS, RAE Argentina and the BBC’s Calling the Falklands Programme. We also looked in some detail at the short-lived Radio South Atlantic which broadcast in May and June 1982 from a requisitioned BBC transmitter on Ascension Island. We asked the British Ministry of Defence to explain how the station was operated. We also analyzed a transmission broadcast on May 20th 1982 (the second night of transmission).

But it was also the last programme in which Wim van Amstel appeared as RNW Frequency Manager. It was certainly not the last time he was heard on the programme, though. Again it is striking to hear some of the predictions – and how they were spot on. The call with Arthur Cushen in New Zealand is rather like making contact with the moon. Cannot believe how fast time has flown.

At the time of publishing this podcast, I was also sad to hear of the passing of BBC correspondent and broadcaster Brian Hanrahan, who famous line when broadcasting under censorship from the Falklands Fleet was brilliant. Unable to reveal how many British aircraft had been involved in the conflict, he reported that after one sortie he “counted them all out and I counted them all back.

MN.26.12.1991.Year End Review

This was a news show 1.6 million tune in to Radio Netherlands in Dutch during their summer holiday. WWV and WWVH have had problems with their automated time announcements. Drum recorders are back on line. Victor Goonetilleke has news about Cambodia. VOA is having challenges building its transmitters at a new site 50km North of Colombo.

Why did we broadcast all these numbers? People forget none of the listeners had access on-line and only a fraction of the audience had access to printed DX bulletins. Andy Sennitt reports on what is in the 1992 World Radio TV Handbook. James Robinson reports that several UK local radio stations are leaving mediumwave. WLS 890kHz is scrapping its FM format. A new Catholic SW station WEWN was being built in Birmingham, Alabama. (The late) Dave Rosenthal reports on an experiment in McMurdo. Remember this show is 24 years old!

Vasily Strelnikov signs off at Radio Moscow World Service and recommends people to tune into Radio Netherlands. Radio Moscow staff watch the red flags of the USSR being lowered.

Thanks so much for sharing these, Jonathan–and Season’s Greetings to you!

I’m looking forward to several hours of listening over the coming days.
