I was meandering around the web this morning and stumbled on to a page where famous key collector and curator Tom Perera W1TP had re-created the morse key setup used by Walter Winchell to introduce and punctuate his radio and later TV broadcasts. They were a pair of Vibroplex bugs.
I grew up in Sydney in the 1950s and remember how radio station 2UE would start their news bulletins with a brisk CQ CQ. They were probably inspired by Winchell. Another memory is watching ‘The Untouchables‘ on TV with narration by Walter Winchell.
Ironically in his early years as a gossip journalist he was close to prominent criminal identities and later became friends with J. Edgar Hoover. He was Jewish and in the lead up to the second world war was one of the first Americans to criticise Hitler and those in the US who supported him. Another of his targets was isolationist Charles Lindbergh. His fame followed his reporting the famous kidnapping and subsequent trial.
From the clip you can hear the rapid-fire delivery. In many ways it’s like a precursor to much of what we consume today.
He attacked the Klan and its supporters. After the war he aligned himself with the Senator Joe McCarthy’s hunt for communists. But within this short clip there are a couple of places where he briefly questions a couple of issues that were to haunt the US for the next couple of decades – Vietnam and cigarettes and cancer.
Complex and probably unattractive, what I want to know is if he actually knew how to handle those Vibroplex keys.
A few weeks back – in the post about wartime crystal production – I made a tangential reference to my all time favourite YouTube video – Claude Paillard F2FO distilling down to less than 20 minutes his meticulous work making a triode valve, effectively by hand. Watching it again, this time I spent a bit more time looking over the many pages of background information he had posted on his website detailing his research into triodes of the 1920s, the techniques he used and the equipment he used or made to complete this project and create a very cute looking valve wearing blue shorts.
This prompted me to start a more methodical reading of the documents, and to work through the translations to ensure I understood what he had done. (Google translate is great, but it missed a significant amount.) If you’re vaguely interested in the technology of the earliest days of radio, and have ever wondered how these valves were made, the documents take you on a special journey through the eyes of an explorer with a brilliant workshop and skills to match. His research is comprehensive. By way of exploring how early valves were made he produces a full detailed and illustrated life story of the evolution of valve types and introduces important valve families like the 6L6 and its descendants like the 6V6 and the 807 of the late 1930s. He also takes you on an excursion to discover the history of creating an effective vacuum, critical in the creation of the valve aka the vacuum tube.
It’s also an enjoyable way to build up a French vocab for the terminology of valve radio gear. Along the way I stumbled across the Electropedia, a brilliant resource for translating technical terms from French to English with a number of other languages included. But some of the terms Claude Paillard uses reflect an earlier era and vocabulary. He talks about the plaque (plate) of a valve rather than l’anode. I’d love to find online versions of the French radio engineering references he cites from the 1920s.
Another plus of this experience is reading the history of radio from the perspective of a country other than Britain or the US. The French version of radio history introduces interesting characters and stories to the familiar names and places. An inspiration behind the work of F2FO is the history of the triode TM (Télégraphie Militaire). A good outline is at Michel Siméon’s website.
Paul Berché was another prolific author of French radio texts.
I’m a great fan of the Prelinger Archives which is home to so many items like this video I’ve heard about recently from various ham radio email lists.
I like how the components of the earliest electronics and wireless were so basic and ‘natural’. Think of hand made capacitors and resistors using traces of graphite on paper. Valves (or tubes) of course were another story but still capable of being ‘homemade‘.
I love the idea that an accurate, literally rock solid frequency could be achieved using a piece of a very common rock – admittedly a pure piece of quartz cut just so.
This video details the elaborate and meticulous manufacture of quartz crystals during World War 2 by Reeves Sound Laboratories in 1943.
The 41’24” video can also be viewed (free of youtube ads etc) and downloaded via the Prelinger Archives.
Most of the ‘radio quality’ quartz was mined in Brazil which ceased its neutrality in 1942 and joined the Allies.
The story of quartz crystals during WWII is told in ‘Crystal Clear‘ by Richard J. Thompson Jr. (Wiley) 2011.
“In Crystal Clear, Richard Thompson relates the story of the quartz crystal in World War II, from its early days as a curiosity for amateur radio enthusiasts, to its use by the United States Armed Forces. It follows the intrepid group of scientists and engineers from the Office of the Chief Signal Officer of the U.S. Army as they raced to create an effective quartz crystal unit. They had to find a reliable supply of radio-quality quartz; devise methods to reach, mine, and transport the quartz; find a way to manufacture quartz crystal oscillators rapidly; and then solve the puzzling “ageing problem” that plagued the early units. Ultimately, the development of quartz oscillators became the second largest scientific undertaking in World War II after the Manhattan Project.” (from the book’s blurb)
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 other day I noticed a very interesting photo on a fellow Australian ham blogger, Peter Mark’s site. The blog entry was titled a “Radio nerd’s tour of Canberra“. The first photo is described as ‘a transceiver with a nifty antenna tuner’. But the instant I saw it I sensed there was slightly more to it.
The fact that it was built on a beaten up old kerosene can prompted me to google “Winnie the war winner” and the results confirmed Peter’s photo is of this most famous piece of Australian ham homebrew ingenuity. Max (Joe) Loveless’ skill to be precise. The photo prompted me to find out the story of this iconic wireless set that’s an inspiration to a generation of Australian radio hams proud of their traditions of ‘making-do’.
The wikipedia entry on the Battle of Timor gives detailed historical and military background to this little radio’s moment of fame in April 1942.
As a result of British intrigue Australian troops were sent to Portuguese East Timor to disrupt any Japanese invasion on Australia’s northern doorstep. By April the 2/2nd Independent Company had been fighting a guerilla campaign for four months. Many were ill and they were low on supplies, and had had no contact with Australia since February.
For weeks a team had been trying to build a transmitter from salvaged parts from damaged radio gear. Before the war Max Loveless was a radio amateur in Hobart with the call 7ML. He became a Signaller with “Sparrowforce” on the Dutch part of Timor with the Australian Infantry Forces (AIF).
Bill Marien reported the story in the Melbourne Argus of 1st January 1943:
“Force Intact. Still Fighting. Badly Need Boots, Money, Quinine, Tommygun, Ammunition.”
This was the first official message received in Australia from the lost AIF commandos of Portuguese Timor who, for 59 days after the Japanese landing on the island, had been written off as missing or dead.
The signal came to Darwin on the night of April 19. It was transmitted by “Winnie the War Winner,” a crazy contraption built from scraps of wire and tin, and pieces of long discarded radio sets.
When the commandos showed me the incredible Winnie recently, it was easy to recapture the scene of that night of April 19.
In the thin air of a Timor mountain hideout, 4 bearded, haggard Australians were working by the smoking, stinking light of a pig-fat flare. Three of them watched anxiously as the fourth thumbed a Morse key. Weak batteries sent the dots and dashes of the morse dimly across the Arafura Sea to the Northern Territory of Australia. The tension was something physical as the operator strained his ears for a reply. At last a reply came.”
The AIF commando force which had been in Portuguese Timor were joined by other Australians from Dutch Timor including two signalmen, Cpl John Sargeant, of Bonshaw, NSW, and Lance-Cpl John Donovan, of Lindfield, NSW. Under leadership of Capt George Parker, of Earlwood, NSW, they joined Sigs Max (Joe) Loveless, of Hobart, and K. Richards, of Victoria, both of the original commando force.
“On March 8 the 4 men got to work — Loveless just out of sick bed and Sargeant just recovered from malaria. Three days later a Dutch sergeant, exhausted, stumbled in. He had carried what he thought to be a transmitter-receiver 40 miles through some of the roughest country in the world. It was an ordinary commercial medium-wave receiving set – and out of order.
CORPORAL WENT SCROUNGING
Loveless, whose knowledge made him No 1 man of the team, thought he could build a one-valve transmitter from parts of this set and of another small and weak set. He planned a circuit, and all the commandos were asked to be on the lookout for anything that might serve as a radio part.
Cpl Donovan went scrounging at Attamboa, on the north coast, to see what he could salvage, while his companions recovered an abandoned army set. The parts of the 3 sets were unsoldered, and a bamboo used to catch all the melted solder for re-use. Loveless had carefully preserved 2 small batteries, but they needed recharging. A generator was taken from an abandoned 10-year old car and rigged to a series of wooden wheels, which a native was persuaded to turn. The set was complete on March 26.
It would not work!
The only tools available were a tomahawk, pliers, and screw-driver. They had no test equipment to determine the set’s frequency. The coils were wound on pieces of bamboo.
On March 28 Donovan returned from Attamboa – laden like a treasure ship. He had the power pack from a Dutch transmitter, 2 aerial tuning condensers, 60ft of aerial wire in short lengths, and a receiving set. Next day the men had to move all their precious gear, for the Japanese were getting too close.
Loveless got to work on a second transmitter twice as big as the first, and built it into a 4-gallon kerosene tin. A battery charger was recovered from enemy-held territory. To get it 14 commandos went through the Japanese lines to the old Australian headquarters at Villa Maria. There, within 100 yards of Japanese sentries, protected only by the dark, they dug up the charger which had been buried when the headquarters were evacuated.
HEARD DARWIN WAS SAFE
On April 10 the signallers heard Darwin on the receiver, and knew then that Darwin was still in Australian hands. But their second transmitter was also a failure.
Loveless had another idea, but he needed more batteries. Four were found. Then the petrol ran out and the charger could not be kept running. So they raided the Japanese lines and carried off tins of kerosene. Finally the charger was started on kerosene and run on diesel oil.
With batteries at full strength they signalled Darwin on April 18, but got no reply. They did not know that their message had been picked up on the Australian mainland and passed on to Darwin, that all transmitting stations had been warned to keep off the air and listen to Timor the following night.
You can get a good sense of the story from this video of the documentary ‘The Men of Timor’ filmed in Timor by Damien Parer in late September 1943. You can see a reconstruction of the building of the radio about 3’16″ in from the start.
On the 19th April they heard Darwin but their batteries failed again.
On the night of April 20 they again got Darwin. But Darwin was suspicious; demanded proof of their identity. So questions and answers like these were rushed across the Arafura Sea:
“Do you know Bill Jones?”— “Yes, he’s with us.”
“What rank, and answer immediately?”— “Captain.”
“Is he there? Bring him to the transmitter. . . . What’s your wife’s name, Bill?”— “Joan.”
“What’s the street number of your home?”
Once they provided the correct answers, help was on its way.
I found the newspaper report on the National Library of Australia’s brilliant Trove, where digital versions of many Australian newspapers have been put online courtesy of crowd-sourced editors across the global internet. Truly astounding!
Only there were more pieces of equipment on display! Justin’s clearly been collecting for a while, specialising in valve gear and the SB series. He had a stash of catalogues dating back to the early 1960s which evoked memories for many of us there old enough for Heathkit – even on the other side of the Pacific Ocean – to have been a radio icon.
Justin filled in the deep history of the company, with its kit airplane beginnings through to its heyday when it actually made economic sense to build your own colour TV!
He also managed to evoke the history of the time – which is some achievement for someone who I don’t think was actually alive for most of it!
MAKE magazine beautifully evokes the times and the anticipation – those long painful delicious moments between posting the order and the kit arriving.
I was especially interested in observations about how the fortunes of the company were in synch with a strong tradition of making it yourself – which seems to be a core part of both the US and Australia. We both have frontier experiences still in our recent folk memory.
I wonder what Heathkit would make of the kit market today if they were still around. They certainly set a benchmark. And they certainly sold a lot of kits over the years.
The Genesis G59 is a very exciting sounding project. I believe I’ll have a pretty impressive SDR transceiver once it’s complete.
While GenesisRadio is more cottage industry in scale than Heath – who grew so much they opened a factory in the UK – the quality is there where it counts. Part of the decision to take the plunge was an estimation of the support both from Nick Hacko VK2DX and the online community of builders on the Yahoogroup.
The then and now comparison shows how much kit building has changed. Kits now can be delivered across the world in days. Speedy support from a global network of enthusiasts is available via email. Documentation is able to be kept up-to-date and builders alerted to important developments. And most amazing, of course, the firmware can easily be updated and improved.
The key to the success of all of this is the social glue of the builders online. That’s another reason not to delay the build and to glean maximum advantage of the communal energy available there.
The Genesis documentation is clear with excellent photos. Not the component by component style of Heathkit, but totally adequate.
So far I’ve completed phase 1 successfully (the power supply) and am in the middle of the second phase (the microcontroller circuit). I’m taking it slowly and really enjoying those moments at the end of the night when I can get to it. That lateness is the one reason I’m taking it slow. The other is – I really enjoy this part!
An ABC News story today tells of the celebrations in Darwin this week marking the start of the Overland Telegraph on 20th June 1870 when the South Australian parliament voted to dedicate about half its annual budget to building the telegraph line!
Barrie Barnes of the SA & NT Morsecodians and others appear in the video accompanying the story explaining the history.
