Broadcast in February 2004 on three PBS television stations in
Illinois
(see News and events).
David and Debra have spent almost a year, researching. filming and editing this
two-hour video. Armed with information from local author and historian, John
Taylor from Bletchley, they visited and interviewed men in their late seventies
who were specially enlisted more than 60 years ago for secret wireless
operations during World War II. As a result of this extensive and fascinating
research, two one-hour documentaries have been made about the secret use of
wireless equipment (much of which was of American manufacture) in the Allies’
battle with the Axis powers.
Part one:
BEYOND BLETCHLEY PARK
This programme is already of great interest to radio amateurs, both in the UK and US. We visit Bob King G3ASE in his shack where he has re-created his wartime listening post when he was a Radio Security Service Voluntary Interceptor. He shows us his restored Eddystone two-valve receiver. Over 1500 ‘VIs’ like Bob listened throughout the UK for enemy intelligence messages in morse code. These were documented, processed and passed on to the famous Bletchley Park codebreakers for decrypting and analysing.
At Bletchley Park we visit David White G3ZPA who founded and runs the Wireless
Museum. He demonstrates a spy suitcase set and tells us about the clandestine
radio station hidden in the roof of Bletchley Park mansion (now famous as
Station X), still equipped with several American receivers from the period. Not
far from ‘B.P.’ is Whaddon Hall, used as an HQ for the Secret Service during
WWII. Here special wireless sets were made and installed in vehicles by Geoffrey
Pidgeon and his team. He and Debra ride in an authentic 1940 Packard, used as a
special wireless vehicle at that time.
After D-Day, British and American military and Intelligence sections at
Bletchley Park needed vital wireless communication with their commanders in the
field inside Europe. Maurice Richardson, an operator at Whaddon’s Windy Ridge
wireless station, tells us how the encrypted messages were received and sent. In
France and Germany, attached to General Patton’s 3rd Army, wireless
operator Wilf Neal tells us of conditions for him and his team, working near the
front line operating an HRO receiver in the specially fitted out Dodge
ambulance.
Part two:
BLACK PROPAGANDA
Not everyone knows that in WWII Britain waged
an extremely effective ‘black’ propaganda campaign against the Germans. The
Woburn estate in Bedfordshire was the setting for most of the wireless
transmissions to Europe, as it was 50 miles from London and out of the bombing
zone. We trace the development and content of the broadcasts with Ingram, son of
Ralph Murray, who was one of the important Foreign Office officials that shaped
the operations.

Phil Luck was a young engineer who operated the RCA 7½ Kilowatt transmitters in
the area, beaming the British ‘black’ propaganda broadcasts to Europe. He
tells stories of the operations, and with Debra in the back of the Packard,
visits the remains of his old transmitter station at Potsgrove. It was here that
he and his team replayed the broadcasts from pre-recorded discs much like a
modern DJ. More remarkable remains are found at the village of Milton Bryan.
Debra visits the ‘black’ propaganda broadcast station there, still almost
intact. She finds traces of switchgear and transmission lights from 60 years
ago. Teleprinter engineer Roy Tink tells some interesting tales about life and
the people at ‘M.B.’ Debra visits Stephen, the station manager Ted Halliday’s
son. They uncover new secret papers and cartoons from Ted’s trunk, which give
a unique insight into what life was like at ‘M.B.’
The Milton Bryan studios were linked by landline to a
gigantic ‘dreadnought of the ether’, an RCA 600 Kilowatt Medium wave
transmitter, code-named Aspidistra, obtained from America. Ingram Murray
describes some of the dirty tricks (for which Britain had an unexpected talent!)
that the transmitter was used for. We hear nostalgic music and extracts from
recordings made of the last two days’ propaganda broadcasts in 1945 (courtesy
of the Imperial War Museum). The mastermind behind the operations was a
journalist called Sefton Delmer, who fought this secret wireless war with the
enemy. Although the efforts of his extremely talented team were demonstrably
successful, because of the secrecy, his triumphs have largely gone unnoticed.
The two one-hour films uncover
just how important wireless communication was in WWII and helped to shorten our
conflict with the enemy.

commemoration event is available to buy in both UK and USA formats. Click

In the past few years, Geoffrey Pidgeon has been writing his own and compiling
many other accounts of secret communications during World War 2. His excellent
new book has now been published, and is thoroughly recommended.
