Clandestine Radios of WWII And Beyond
By Brian Harrison
"Spy radios" came into their own during WWII, and were commonly used during the 1950s - 1960s and up through the end of the Cold War (at least!). This session will discuss and demonstrate a number of the more popular purpose-built portable radio transmitters and receivers used by spies and military intelligence such as the famous British B2 set and the American PRC-1, PRC-5, SSTR-1, RS-1, and RS-6. Many of these radios are still available and all are fun (and challenging!) to use on today's HF ham bands, CW only! Also two very unusual WWII radios designed to help locate clandestine transmissions and put them “out of business” will be discussed and shown.
