Free online lecture: “Aspidistra and the Broadcast Group of the Diplomatic Wireless Service”

Many thanks to SWLing Post contributor, Kris Partridge, who shares the following information about a free online lecture hosted by the The Institute of Engineering and Technology. This presentation will take place tomorrow (September 8, 2021 staring at 19:00 BST/18:00 UTC). You must register online to attend this lecture.

Here are the details from the IET website:


Aspidistra and the Broadcast Group of the Diplomatic Wireless Service including the wartime transmission of black propaganda.

The History of the Broadcast Group of the Diplomatic Wireless Service. The event starts at 19:00 BST on 8th September 2021

This is the story of Broadcast Group of the Diplomatic Wireless Service (DWS) which had its origins in the Political Warfare Executive (PWE) at the beginning of WW2. In 1972 it was amalgamated into the administrative structure of the Foreign and Commonwealth Office (FCO) and was renamed Communications Engineering Department (CED). The latter had two groups, Broadcast Group which was responsible for transmitters carrying many of the BBC’s World and Vernacular services, and Communications group which provided radio communications to embassies for diplomatic traffic. In 1986 CED’s Broadcast Group was taken over by the BBC.

In this illustrated talk we will learn first about the transmission of black propaganda and associated activities during WWII. Also such activities as trying to interfere with enemy rocket guidance systems. Then about the various Medium-Wave and Short-Wave transmitting stations of Broadcast Group with transmitter stations at Crowborough, Orfordness, Cyprus and the island of Masirah, a part of Oman. Transmitters ranged from 1?kW carrier power to 600 kW. Several of these were designed and manufactured in house. There will be many pictures and descriptions of the equipment and aerials used at these stations. Also covered will be an introduction to the progress of amplitude modulation techniques which enabled transmitters to become more compact.

So, what is Aspidistra? Please register to hear the story of Aspidistra and the Broadcast Group of the DWS with the engineering used to build and operate these stations.

About the Speaker

Roger Castle-Smith FIET

Mr Roger Castle-Smith FIET. Roger first became interested in radio when he joined the signals section of his school’s Combined Cadet force. This led to him gaining an amateur’s radio license at the age of 15, callsign G3IOT. Then on to the Royal Military Academy, Sandhurst, where he started an amateur station for the academy. Graduated into Royal Signals. Achieved a BSc(Eng) degree as an external degree from the University of London whilst at the Royal Military College of Science. Many of his army postings were of a technical nature. On retirement at the age of 37 he was made a MBE. Joined the Diplomatic Wireless Service then worked his way up to becoming Head of Broadcast Group in 1979 leading to Chief Engineer and Head of Communications Engineering Department (CED) in 1981. During his service a CBE followed his MBE. Retired age 66.

Radio South Atlantic: recording of a short-lived clandestine radio station

Crosley-Dial-BlackAndWhite

In reply to our recent post about Radio Atlantico del Sur, SWLing Post contributor, Jonathan Marks, adds:

Radio South Atlantic was a short-lived clandestine radio station started by the UK Ministry of Defence with programmes aimed at Argentine troops on the Falkland islands. This programme was broadcast from a transmitter on Ascension Island which was temporarily taken away from BBC World Service.

The Falklands War (Spanish: Guerra de las Malvinas), also known as the Falklands Conflict, Falklands Crisis and the Guerra del Atlántico Sur (Spanish for “South Atlantic War”), was a ten-week war between Argentina and the United Kingdom over two British overseas territories in the South Atlantic: the Falkland Islands and South Georgia and the South Sandwich Islands. It began on Friday 2 April 1982 when Argentina invaded and occupied the Falkland Islands (and, the following day, South Georgia and the South Sandwich Islands) in an attempt to establish the sovereignty it had long claimed over them.

On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with the Argentine surrender on 14 June 1982, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel and three Falkland Islanders died during the hostilities.

This is a studio copy of Radio South Atlantic. In May 1982, the British government decided to set up a Spanish language radio station targeting Argentine troops. This was probably in response to an Argentine radio station (nicknamed Argentine Annie by the UK press) which appeared on shortwave some weeks earlier using the Beatles theme “Yesterday” as a signature tune.

I was editing the Media Network programme at the time. We could hear Radio South Atlantic in Hilversum – but the signal was very weak. So I rang the British embassy in the Hague and asked if it would be possible to get a studio copy of the programme to use in a documentary feature we were making. A few days later, a courier riding a large motorbike arrived at RN’s reception and asked for me. I went down to the front-desk to sign for the tape. “But you can’t keep this tape. You can only listen to it” was the message from guy in the helmet. “I have to take it back to the Hague in about half an hour”. I said I’d look for an empty studio, gave the guy a large coffee and wandered casually round the corner. Then I made a mad dash to the fast copy-room used to make tape copies of RNW transcription programmes for other radio stations. It had a machine that could copy tapes at around 8 times faster than normal. Luckily, Jos, the guy in charge, saw my challenge, set up the machine immediately and 15 minutes later I was back in reception to return the tape to the messanger. And I had a copy.

It seems the British dropped leaflets over the Falklands to try and spread the word that this shortwave radio station existed. And we later analysed the programme. It was classic Sefton Delmer (Black Propaganda), although rather poorly presented. Bit like calling up Vera Lynne if the British had a dispute with France.

But this is one of the few surviving recordings of Radio South Atlantic. You be the judge of how effective it all was. http://jonathanmarks.libsyn.com/radio-south-atlantic-may-1992

This is an amazing recording, Jonathan.  I’ll admit that I had never heard of Radio South Atlantic before and never knew a UK-supported clandestine station was on the air during The Falklands War/Guerra de las Malvinas.

Thanks for the excellent history lesson and your own (clandestine) recording!
