German spy radio set - this page is a stub

The ESK-632 was an HF spy radio station for CW signals (morse), developed by Telefunken in Hannover (Germany) in 1954 for clandestine operations of the French intelligence services. The radio was based on the ESK-52 but was also suitable for speech transmissions in AM (phone).

Like its predecessor, the design of the ESK-632 is based on the wartime British Type 3-Mark II (B2). For security reasons, both transceivers were listed as Amateur Radio Set.
