Cold War Spy Radio

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.

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.

This is the FS-5000 cold-war spy radio. It was developed for use by NATO and western secret service agencies. It was manufactured by AEG Telefunken during the eighties (later acquired by DASA). The radio covers 50kHz to 30MHz in 1 kHz steps.

It is completely self contained, including batteries and an automatic antenna tuner. It is built like a tank, extremely robust but still light weight. It was designed to fit comfortably to fit in a diplomat case, so that it could be transported under the protection of diplomatic immunity on planes. The radio was designed to receive and transmit encrypted text messages, so a radio modem is built in. See for more information http://www.cryptomuseum.com/spy/fs500…
