Cold War-era Soviet R-014D electronic burst encoder, codenamed 'Datchik,' as used in conflict areas to transmit battlefield commands. The unit measures 14″ x 10″ x 7″, and features a 16-key keyboard, lamp panel display, voltage meter, voltage check switch, mode selector, and on/off switch. The unit allowed the operator to transmit a message in Morse code at a very high speed, helping to evade interception and radio direction finding. Given the importance of the data sent, the device incorporated advanced error-detection and error-correction. In very good to fine condition.
