At the outbreak of World War One, Russell Clarke was practising as a barrister in Aberavenny and operating as a wireless amateur using the callsign THX. Together with his friend and fellow wireless amateur Baynton Hippisley based in London, he began isolating wireless signals being sent from overseas espite the official call to confiscate all privately-owned wireless receivers. The two had isolated and reported a number of regular signals they believed to be from German naval wireless stations at Neumunster and Norddeich.
Their report was passed onto the Admiralty's Intelligence Division and so, along with many other such amateurs, they were sent to work for Naval Intelligence as 'voluntary interceptors' (VIs) and reported their signals intelligence back to Room 40.
Together with Baynton Hippisley, Russell Clarke was sent to Hunstanton, Norfolk to establish a listening station there. The two amateurs were given permission to set up a listening post at Hunstanton, the highest point nearest the German coast which eventually became the basis for 14 listening posts
