FS 5000 receiver demo - Cold War Spy Radio

This is a demonstration of the receiver section of the FS-5000 cold-war shortwave spy radio, developed during the eighties by the government branch of AEG Telefunken which was later acquired by DASA (Deutsche Aeropspace). The FS-5000 receiver is synthesized in 1 kHz steps and covers the entire span from 50 kHz to 30MHz. In this demo it receives an SSB station in the 17m ham band as well as a broadcast station in the medium wave band (1200kHz). The receiver is of the single sideband type with crystal filters for 300Hz and 3kHz. The receiver has an FSK demodulator built-in. The FS-5000 system was primarily developed for the reception and transmission of encrypted text messages.
