England, 1942: Having fled Germany after her father was captured by the Nazis, Lilli Bergen is desperate to do something pro-active for the Allies. So when she’s approached by the Political Warfare Executive, Lilli jumps at the chance. She’s recruited as a singer for a radio station broadcasting propaganda to German soldiers – a shadow network.

The Aspidistra Radio Transmitter by Deborah Swift

The Shadow Network which forms the title of my latest book refers to the fake news radio stations set up by Sefton Delmer in WW2. These secret radio stations operating in WW2 pretended to be genuine German radio stations and employed German prisoners of war or other German speakers to make their broadcasts. 

The broadcasts were deliberately racy and were designed to capture the hearts of ordinary Germans and make them believe they were listening to a forbidden radio station from their own country. Their popularity spread, and they got wide audiences for their programmes.

The radio signal for these ‘fake news’ radio stations needed to be strong enough to appear as though it came from Germany and had to be more powerful than anything that was then available.

Harold Robin

By coincidence, the Radio Corporation of America (RCA) had created two high-powered radio transmitters which could not be used in the US, because of a change in American law. The RCA were eager to sell them to Britain. So Harold Robin, a Foreign Office radio engineer, saw their potential, and travelled to America to examine them, and then worked to improve them. 

He adapted a transmitter so it was able to move frequency in a fraction of a second, at the flick of a switch.The powerful ex-RCA transmitter, eventually installed in Sussex, England, was named Aspidistra, referencing the popular Gracie Fields song ‘The Biggest Aspidistra in the World’, in which an Aspidistra houseplant grows until it ‘nearly reached the sky’.

In fact, most of the technology was buried underground at the site at Crowborough, though its antennae were visible – three guyed masts, each 110 metres tall, directing the signal broadly eastwards. The Art Deco–style transmitter building was housed in an underground shelter which had to be excavated by the Canadian army troops who were stationed nearby.

Intrusion operations

The Aspidistra mast was so powerful it could be used to intercept German frequencies. During Allied air raids, German radio transmitters were switched off so the Allies couldn’t use them to locate their installations.

 
As soon as the Germans switched off their masts, Aspidistra began transmitting on its frequency, just like the German station. The transition was seamless and German listeners believed the original station was still broadcasting. Aspidistra operators would then insert pro-British propaganda and fake news into the broadcast as if it was coming from official German sources.

Radio Transmitter

After the war, Aspidistra was used by the BBC. It made its final transmission on 28 September 1982, before being finally switched off by Robin, the man who had been responsible, forty years earlier, for bringing the transmitter from the US and setting up the station at Crowborough.

In my novel based around the Aspidistra transmitter and the fake news radio stations, I include a fictional plot to blow up the transmitter. Although fictional, this is not unlikely as there were several attempts by the Germans to sabotage infrastructure and communications systems in England at the time.
