Help Brian identify this 1970s era interval signal

[Mystery solved! Click here to read the update.]

Many thanks to SWLing Post contributor, Brian (W9IND), who writes:

I want to thank you for stirring a memory that I never thought I’d relive – even though it still doesn’t solve the mystery of what the heck I was listening to in the first place!

Back in the early 1970s, I was a teenage SWLer with a curiosity for the worldwide signals that emanated from the speaker of my shortwave radio. Bitten by the SWLing bug after stumbling across Radio Nederland’s Bonaire relay station, I spent many a happy hour twirling the dial in search of fresh game to hear and QSL.

But on one such occasion (I’m going to guess it was in 1971), I was surprised and fascinated by what sounded like a snake-charming horn playing notes at random. Stranger still, the transmission would seemingly go off the air for a couple of seconds and then return to play the strange melody again. I chalked it up to one of the countless beeps, hums and other electronic noises that often appeared on utility frequencies in those days.

I never recorded it, I never had a clue what it was, and I never heard it again.

Until recently. On the Shortwave Radio Audio Archive.

A couple of weeks ago, while looking for old shortwave interval signals from the 1970s, I saw a recording marked “Unidentified interval signal 1” listed right after the interval signals of Deutsche Welle and Radio Nederland.

“OK,” I thought. “Sounds like a challenge. Maybe I can even help figure out what it was.”

Then it played … and I almost fell off my chair! I literally sat with my mouth open as the long-lost sounds of the “snake-charming horn” played again. Could it indeed have been an interval signal – and if so, for what station?

I wanted to contact the person who recorded it, but then I learned the sad news that Mr. Greg Shoom is no longer with us.

So I remain mystified, probably forever. But it sure was fun hearing that weird recording again! Thanks for the memories.

Let’s see if an SWLing Post reader can help, Brian!

I know of at least a dozen readers who are experts on all that is interval signals, so hopefully someone can listen and ID this one.

I’ve embedded audio from this SRAA recording below. Note that the unidentified interval signal can be heard between time marks 1:27 – 2:07 in the following recording:

Can you positively ID this interval signal?  If so, please comment!

Shortwave Radio Audio Archive: A treasure trove of radio history and nostalgia

One of the most amazing things about hosting and curating a massive collection of shortwave radio recordings is listening to each recording as they’re published on the site.

I created the Shortwave Radio Audio Archive (SRAA) in 2012 as a dedicated space to post and share off-air recordings with the world. Listening to SRAA recordings and subscribing to the podcast is 100% free, and entirely void of any advertising. The fact is, I pay for this site out of my own pocket, although some of your generous coffee fund and Patreon gifts are used to reinforce the archive’s longevity and future.

Not only does the SRAA serve as a historical record of radio–and even as audio samples for musicians–it’s also for radio listeners like us to enjoy.  We have over 3000 podcast and RSS subscribers. We invite you to subscribe as well as to contribute content in the form of your own radio recordings!

Great content, great contributors

Speaking of recordings, check out a sampling of our latest offerings from our amazing contributors:

One of our contributors on the Shortwave Radio Audio Archive, Tom Gavaras, has been sharing some brilliant airchecks. I also discovered that Tom runs an amazing site simply chock-full of Minneapolis/St. Paul airchecks. Tom writes:

Hi Thomas,

[…]As an FYI … I own/run a website called RadioTapes (www.RadioTapes.com). It features more than 2,000 airchecks of Minneapolis/St. Paul radio stations dating back to 1924. You will also find some shortwave recordings that I previously posted (on the Special Postings page).

In addition to my collection, the website includes airchecks provided by more 100 contributors. RadioTapes also has a Facebook page with 1,400 followers.

Post readers: I strongly suggest you check out Tom’s amazing archive of airchecks.  If you ever lived in or DXed the Minneapolis/St. Paul market, you’ll certainly hear some familiar voices and IDs.

Thank you Tom!

From the Shortwave Radio Audio Archive: VOA and BBC on the anniversary of moon landing

There are a hundreds of fascinating off-air radio recordings in our Shortwave Radio Audio Archive.

One of our frequent contributors, Tom Laskowski, has digitally converted numerous magnetic tape recordings from his personal collection to share with the archive. Tom made the following recording of the Voice of America on July 20, 1979 at 0500 UTC on the 31 meter band.

Tom notes:

The first 4:30 is from a VOA newscast that aired before the main part of the program.

The main recording was presented on the 10th anniversary of the Apollo 11 moon landing. I enjoy listening to this every year on the landing anniversary.

I’ve enjoyed listening to this 10th anniversary presentation as we, today, celebrate the 50th anniversary of the moon landing::

[Update:] Tom also shares another recording that marks this anniversary:

I thought this might be [another] appropriate file to upload considering we are  marking the 50th anniversary of Apollo 11. I recorded this program thirty years ago on July 20, 1989 [5.975 MHz at 0400 UTC] the 20th anniversary of the Apollo 11 moon landing. Omnibus takes a look back at the historic Apollo mission and how and why it happened:

Thank you so much for sharing this, Tom!

Space Flight: Colin’s collection of Radio Moscow recordings on the Shortwave Radio Audio Archive

One of the joys of running the Shortwave Radio Audio Archive (SRAA) is that, over time, more and more people have become aware of it and submit recordings they’ve had in their private collections for decades.

Quite often, SRAA off-air recordings were originally made on reel-to-reel or cassette tapes which degrade with time. When SRAA contributors take the time to digitize these recordings, and share them via the SRAA, they put these collections in the hands of hundreds of archivists. We’re grateful each time we receive one of these shortwave or mediumwave/AM recordings.

You can imagine my excitement when I received the following message from one of our newest contributors, Colin Anderton:

“As a space flight nut, I have many recordings from the 1970s from Radio Moscow. They used to broadcast on the medium wave, and I used to record the news bulletins during some of the space flights. In particular, there was a period between December 1977 and March 1978 when Soviet cosmonauts first lived aboard the Salyut 6 space station.  I recorded each days’ news reports on the flights, and also some additional items about them.”

Colin’s recordings are amazing. Here’s a sample from December 10, 1977:

We’ve started publishing Colin’s recordings on the archive at regular intervals.

Interestingly, I discovered that Colin also has a website dedicated to NASA highlight recordings from the space age.  Several months ago, he spent a considerable amount of time making the public domain series more listenable–removing voice-actuated recorder noises, tape clicks, etc.

Colin has made his collection of re-engineered NASA recordings free to download on his website. If you download and enjoy his recordings, consider dropping him a donation. If you’re into spaceflight like I am, you’ll certainly enjoy this collection:

Colin, once again, thanks so much for adding your off-air recordings to the Shortwave Radio Audio Archive!

Indeed, thanks to the many contributors who make the archive such a treasure trove of broadcast recordings! Click here to browse the Shortwave Radio Audio Archive.

Shortwave Radio Recordings: KNLS test transmission circa 1983

We’ve just posted yet another excellent recording by Tom Laskowski to the Shortwave Radio Audio Archive. I thought a number of Post readers might appreciate this one.

Tom notes:

KNLS – Anchor Point, Alaska, from what I believe is a test transmission on August 1, 1983. According to Wikipedia, KNLS signed on the air July 23, 1983. The program consists of the sign-on ID in English and Russian then is mostly a mix of Big Band music. This recording is 31 minutes long.

Tom’s receiver was a Sony ICF-2001 and he started recording at 09:00 UTC on 11.820 MHz. His location, at the time, was South Bend, Indiana (USA).

Click here to download the recording as an MP3, or simply listen via the embedded player below:
