Whaddon: Secret life of village that helped crack WW2 code

On May 9, 2016, Milton Keynes Amateur Radio Society members operated GB1SOE to establish contact with French special event station TM75SOE using WWII equipment

This was to commemorate the 75th anniversary of the first transmission sent back to Whaddon Hall, Buckinghamshire, by Special Operations Executive (SOE) agent Georges Begue. They operated from Whaddon Hall during Monday using a replica MKIII transmitter and HRO receiver,  on the French side a WWII B2 spy set was used.

The BBC report: The Codebreakers at Bletchley Park are well known for their top secret work which helped to change the course of the World War Two.

But the Buckinghamshire village of Whaddon, just a few miles down the road, has long been forgotten, despite the vital role it played. It was codenamed Section 8 and was a satellite station for Bletchley Park.

It is hoped a new memorial will give it its rightful place in history.

Update: Please read Brian’s update regarding frequencies.

SWLing Post contributor, Brian D. Smith, writes:

“Thought I’d forward you this information on the annual “Night of Nights” event on July 12 (U.S. local time)/July 13 UTC, which provides an opportunity for shortwave QSLs – assuming the listener understands Morse code!

I’m sure you’re familiar with this one-night-a-year happening, in which maritime radio stations rise from the dead and transmit Morse code messages again for a few hours.

As a guy who honed his CW sending skills by listening to these stations’ constantly repeating messages, I have a sense of nostalgia and gratitude toward these stations, which helped me obtain my first Novice license, WN9ICB, at the age of 15 … less than 2 months after I taped the WWV recording that I submitted.”

Many thanks for the notice and sharing your nostalgia! Brian also forwarded an announcement from the Maritime Radio Historical Society of America. The MRHS describe the event:

It’s that time of year again. Time to honor all those ops who came before us by preserving their skills, traditions and culture through on the air operations.

Why 12 July? Long time True Believers know the story. But it may be worth repeating for new arrivals and to remind everyone of the traditions we hope to keep alive.

On 12 July 1999 some very tough looking grizzled old radio pioneers had tears in their eyes as the last commercial Morse code radiogram was sent. It was the end of an era. And as the last beeps faded away into the static they witnessed the end of the career to which they had devoted their lives.

These men – and some women – had stood watch over the airwaves on shore and at sea. Theirs was mostly the business of maritime commerce. But when their ship was in peril they were called upon to send the most electrifying three letters in radio, S O S, knowing that all their fellow radio operators would press their earphones close to get every scrap of information and bring aid to their stricken ship.

Once, our coasts were dotted with great Morse code radio stations, all communicating with ships at sea. They’re all gone now… all except one, the one they called the Wireless Giant of the Pacific, located at Point Reyes.

On that sad day in 1999 another event took place. The Maritime Radio Historical Society (MRHS) was formed. We made it our life’s work to honor the men and women of wireless by restoring that wireless giant. One year and one minute later the giant’s voice once again spanned the oceas as we picked up the thread and kept the faith with our colleagues of the air.

Every year since, in an event that became known as the Night of Nights, Morse code station KPH has returned to the air, joined by KFS and the station of the MRHS, KSM.

This year our friends and colleagues at USCG station NMC have labored mightily to bring that storied call sign back to life on Morse code for the evening along with NMQ in Cambria, CA..

And station NMW in Astoria, OR will be on the air as well.

Stations WLO and KLB will join us again as hey have in years past.

This is a global and local event. Hundreds of listeners around the world will be waiting with their earphones on, waiting for the signals of the great station to once again arc over the dome of the Earth to their receivers.

You can be with us in person!

The frequencies for this event are numerous! I have listed the USCG (NMC) frequencies below, but please check the MHRS newsletter for MRHS and other maritime station frequencies.

Again, Brian, thanks for the heads-up!

Happy listening, everyone!

This is brilliant, Martin! I just started searching through the recordings at the Open Society Archives–an impressive collection. Thanks again!

Radio Botswana, 1987 Style

No seasoned shortwave DXer can forget one of the most distinctive interval signals ever–the “barnyard animals” which marked the beginning of the broadcast day of Radio Botswana, Gaborone, for decades.

On its long-time frequency of 4820 kHz, Botswana was an occasional catch for me from the Seattle USA area. I yearned for clearer, more reliable reception of this station and other Africans which my East Coast USA DXer pals enjoyed!

It was always fun–and a DXing challenge–to catch Radio Botswana’s interval signal and sign-on announcements, but it was typically mid winter for reception in Seattle. Propagation on 60 meters needed to be favorable to enjoy anything other than a weak, barely listenable signal. Imagine my surprise and excitement when on the evening of December 27, 1987 I came upon the following signal booming in on 4820 kHz, far, FAR better than any previous Botswana reception. Indeed, their signal that evening surpassed in clarity even the Papua New Guinea and Indonesian “regulars” I would hear on the tropical bands from the Northwest USA.


This recording begins with the famous barnyard animals interval, the beautiful Botswana national anthem (Fatshe leno la rona, or This is Our Land in English) and is followed by a full list of broadcasting frequencies and times in English and the (presumed) Setswana language. That information is followed by a flute instrumental version of the Christian hymn Beautiful Savior, which introduces a short devotional or scripture message. The 10 minute recording wraps up with an a cappella children’s choir.

My receiving setup for this 1987 recording was an ICOM IC-R70 and a 300 foot long random wire antenna. Such a long antenna is unusual for the middle of an urban area, but I took advantage of living in a 3rd floor apartment across from a small city park. One midweek day, while most folks were at work, I managed to string out this long antenna with very small diameter braided steel wire from the 3rd floor apartment balcony to a distant treetop. This “sloper” antenna had significant directivity to the northeast, which happens to be the bearing for many African stations heard from the Pacific Northwest USA. The small diameter wire was suspended so high that it was virtually invisible from ground level.

Antenna orientation for 1987 reception of Radio Botswana. I'm sure this urban location is plagued by QRM and radio frequency interference now in 2016! My ICOM IC-R70 receiver handled the strong signals from nearby MW & FM broadcasters surprisingly well with the addition of a Grove Tun3 Mini-tuner preselector.

I continued to log Radio Botswana occasionally on 60 meters until the station eventually left the air (early 2000s I think), but I never heard them again with such a strong, clear signal as in late December 1987!

Shortwave Radio Recordings: KNLS test transmission circa 1983

A.4towers3antennas

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).

We are fortunate to have a number of active contributors to the Shortwave Radio Audio Archive who have dusted off old magnetic tapes and digitized them for all to enjoy. One such contributor is Paul Harner, who has submitted a number of recordings the past few months. Paul recently submitted a 1976 recording of What’s New from Radio Netherlands.

Paul notes:

Radio Nederland’s “What’s New” was a Saturday night program that featured hits from the weekly Dutch Top 30. The show was co-hosted by American Bruce Parsons and Australian Graham GIll. Based on the charts from that week, this show aired on 6 November 1976. Shows like “What’s New” introduced me to pop/rock artists that didn’t receive airplay in the USA. It also introduced me to other shows on Radio Nederland later on, such as “His And Hers,” “Happy Station,” and especially “Media Network.”

1953 film anticipates the transistor’s impact on technology

TheTransistor-Film

Many thanks to an SWLing Post reader who shared this brilliant 1953 documentary film about the anticipated impact the transistor could have on technology.

Here’s the film description from the AT&T YouTube channel:

Made between the 1947 invention of the transistor at Bell Labs and the 1956 awarding of the Nobel Prize for Physics to its creators, this documentary is less about the discovery itself than its anticipated impact on technology and society. The intent of the film was clearly to give the public of that era their first understanding of what a transistor was and why it mattered so much.

Made for a general audience, the film provides a clear and concise presentation on technological developments that began with the vacuum tube, showing different types of transistors and explaining the significance in their ultimate replacement of tubes.

Included are visions of “things to come,” concepts and creations of how the small transistor might free up an encumbered world: the wrist radio, similar to Dick Tracy’s, but with a cool lapel sound speaker worn like a boutonniere; a portable TV set, which must have seemed astonishing at the time given the huge, heavy cabinetry required to accommodate the plethora of tubes inside 1950s TVs; and the “calculating machine,” or computer, whose size, we’re told, will one day be so reduced because of transistors that it will only require “a good-sized room” rather than a space the size of the Empire State Building. The concept of how small computers could be still remained decades away.

While The Transistor’s vision of the future seems somewhat quaint in retrospect, it captures a moment in time before the transistor became ubiquitous; a time when Bell Labs wanted the world to know that something important had occurred, something that was about to bring tremendous change to everyone’s daily lives.
