Compact radio receiver or control unit, rectangular in shape and enclosed in a dark brown Bakelite housing. The front panel features a horizontal frequency dial window, calibrated in kilohertz (kHz) from 175 to 215, with a red tuning marker. The Telefunken diamond logo appears both above and below the central control area.
The center of the panel contains a rotary selector knob surrounded by labeled input/output ports and two secondary adjustment wheels on either side, made of ivory-coloured plastic. The casing includes several mounting holes, metal fittings, and recessed connectors for signal or power cables.
This device is marked as “PE 484/3”, identifying it as a core module from the Telefunken PE-484 field communication system — a portable German WWII radio receiver set designed for military and possibly air force signal coordination.
