Perfect Straight-Key Morse Code? Can It Be Made Without Machines?
How I Reunited Two Devils Brigade Canadian and American Veterans of World War Two
In the 1990s while living in eastern Montana, I had the amazing experience of reuniting two soldiers that served in the Devil’s Brigade. They both trained near Helena, Montana.
One day, I was operating on the amateur radio shortwave Ten-Meter band, and a gentleman answered my, “CQ, CQ, CQ, this is N7PMS in Montana, Over”. I took notes of our conversation.
The next day, when again I called for any station to answer my call for a conversation, another fellow, from Canada, answered me. I learned something amazing: Both of these two men mentioned that, during World War Two, they both were in the same special forces unit, training near Helena, Montana.
One of these Veterans served in the Canadian Armed Forces, and the other in the American Armed Forces. Listen to my story, for the full details of this amazing experience I had as an amateur radio operator.

This certainly was one of the most memorable moments in my amateur radio hobby experience! The joy of reuniting friends is good.
From https://en.wikipedia.org/wiki/First_Special_Service_Force:
The 1st Special Service Force (also called The Devil’s Brigade, The Black Devils, The Black Devils’ Brigade, and Freddie’s Freighters), was an elite American-Canadian commando unit in World War II, under command of the United States Fifth Army. The unit was organized in 1942 and trained at Fort William Henry Harrison near Helena, Montana in the United States. The Force served in the Aleutian Islands, and fought in Italy, and southern France before being disbanded in December 1944.
The modern American and Canadian special operations forces trace their heritage to this unit. In 2013, the United States Congress passed a bill to award the 1st Special Service Force the Congressional Gold Medal.
Thank you for watching, and sharing. Comments are welcome: do you have a memorable moment in your radio hobby experience on the air?

Hidden heroes
The BBC have just broadcast and put on YouTube an excellent hour long documentary about two people whose wartime work is credited with shortening the war and saving millions of lives. Yet because of the cold war and the climate of secrecy, credit came late or not at all.
‘Code-Breakers: Bletchley Park’s Lost Heroes‘ details the work of young mathematician Bill Tutte who broke the German’s top-secret Lorenz code and Post Office engineer Tommy Flowers who built the first electronic computer ever – to replace ‘Heath Robinson’, the mechanical device used to process the code-breaking.
Bill Tutte and Tommy Flowers were both ‘scholarship boys’ who benefitted from the best educational and research opportunities available to their generation. Earlier conflicts may not have been able to discover and develop such talents. (And it’s questionable whether comparable educational opportunity is available today.)
It’s hinted towards the end of the program that the extended secrecy about their achievements is connected to the assumption that the Soviets continued to use the captured German Lorenz system into the 1950s. You can only imagine Tommy Flowers’ frustration, biting his tongue every time someone referred to ENIAC as the first computer!
You have to marvel at the beautiful minds of these two men – dealing with complex matrices and patterns and the logic associated with understanding them – without the tools we take for granted today. One of my favourite scenes is Bill Tutte at his desk with a hand drawn grid on a large sheet of paper tracking the pattern of the characters in the coded messages.
The unfortunate & epic saga of the perfect military radio

The long awaited but ultimately unwanted GMR radio |
As my day job starts to include more long term projects & project management I was particularly intrigued by an article in arstechnica.com. The article is, “How to blow $6 billion on a tech project“, although the title may be more inflammatory than technically accurate.
The article covers the 15 year development of an advanced & unified military radio communications system that suffered from multiple issues including scope-creep & a rapidly changing underlying technology.
If you are involved with a group that is working to develop a product or service you’ll really get something from this article. If you interested in radio systems, military or otherwise, you’ll find this interesting as well.
Its hard to image the frustration people suffer when contributing to a project that is mismanaged unless you have been there yourself. I hate to think of the wasted effort that resulted when people found out How to blow $6 billion on a tech project
Monitoring Odyssey Dawn
One of the most memorable DX programs was Radio Nederland’s Media Network presented by the energetic and innovative Jonathan Marks. Both the program and the presenter live on in different guises.
I remember being astounded to hear intercepted military signals from the early hours of the Falklands War being broadcast on the program. Long before crowdsourcing or the internet, Jonathan Marks had a network of highly skilled shortwave enthusiasts and gave them a destination – a tape recorder linked 24/7 to a phone number – where they could leave recordings they had made along with relevant details like time, frequency and identifying callsigns etc. From memory he had sounds of commands being issued by the Argentine Navy to the Belgrano.
After almost 20 years on air the last Media Network was broadcast in 2000. The program morphed into a weblog in the northern spring of 2003 as war broke out in Iraq.
I was reminded of Jonathan Marks’ ingenuity by reports this week of another radio enthusiast based in Holland and how his monitoring activities revealed a US Psyops broadcast as part of the current ‘Odyssey Dawn’ operation in Libya. It was heard on 6877kHz at 0900Z Sunday 20 March.
In fact Jonathan Marks may have been one of the sources of this latest story! It appeared on his Critical Distance blog the day before.
Now in place of Media Network’s phone and cassette recordings, we have blogs, twitter and audioboo! And a torrent of information.
The Milcom Monitoring Post blog is pulling material together including mp3 clips. But the action and spots are moving very fast. The most appropriate tools appears to be twitter feeds. The source of the psyops recording is @FMCNL. Other monitoring tweets come from @MilcomMP and @QSLRptMT, occasionally using hashtags such as #odysseydawn or #libya.

@cencio4 David Cenciotti is an aviation writer and he’s published comprehensively detailed daily ‘debriefings’ of Operation Odyssey Dawn. His writing is clear and military acronyms are de-coded and explained. The posts on his blog reveal an deeply informed understanding of strategy and a profound knowledge of the aviation industry. His analysis shows how even in the heat of battle there’s some high powered marketing going on!
Here are some of the frequencies that were being monitored in the early stages of the campaign:
4196.0 Naval Military style CWC tracking net USB (American English accents). AGI (3/21 @ 2150 UTC). Early on in Operation Odyssey Dawn that was used as a NATO AWACS tracking net USB: Callsign Magic ##/NATO ##

Seems like a good time to sign up for and account with www.globaltuners.com to get my radio ears a little closer to the action. If you follow any of the twitter accounts mentioned above you will have no shortage of up to the minute details of air (and radio) traffic to follow.
