This is a "stay behind" radio with a crypto component to it.
Nearly all of them are missing the control unit with crypto
(DSU). Such is the case for the example below.
The frequency coverage is 500 KHz to 30MHz on receive and
2MHz to 30MHz on transmit at an output power of 25 watts. It was
designed in the late 1980’s by Telefunken for use by different
NATO partners.The system was designed for short code burst
messages that can be pre-programmed in the DSU control unit and
transmitted at a preset time.
A small batch of these radios was released in 2005 via Fair
Radio in the USA but without the control units.
For an excellent description of the
FS-5000 and more photos, please visit the Cryptomuseum web
page. The name of the complete system was SY-5000.
