Kama   T-47/50
Body wearable covert radio - under construction

The T-47/50, codenamed KAMA 1 , was a solid-state battery powered body wearable covert transceiver developed in the USSR around 1968. The radio was intended for use by the intelligence services of the USSR, such as the KGB, and was used for surveillance operations.

KAMA consists of a so-called body pack (main unit), a detachable remote control unit (RCU) and various accessories. The body of the KAMA radio is somewhat curved, so that it can easily be hidden under the operator's clothing, where it was usually carried in some kind of harness.

The physical appearance of the radio greatly resembles that of the Sinitsa radio direction finder that was built in the same era. In fact it even shares some of its accessories, such as the speaker and the vibrator.
