Cold War–era Czech MRP-4 radar locator, codenamed 'Barbara,' designed for the direction finding of mobile radar and radio stations. The unit measures 7˝ x 10.5˝ x 2.5˝, and includes its wooden transit case with accessories including power packs, earphones, cables, test unit, pack of spare diodes, and more. The top has two circular antennas for high and low band, and the main control panel features a meter; adjustment knobs for tone, range, amplifier, and mode; detector diodes; and an audio output. The MRP-4 was used on tanks and reconnaissance vehicles and worn directly on the chest of an officer while hunting for hidden radar and radio devices. It was also used for locating transmitters attached to passive covert listening devices. In very good to fine condition, with a crack to the meter's plastic window but a spare meter is included.
