R-880

is a Medium and Long wave receiver, used in the complete Warsaw Pact.

This solid state receiver was used for air traffic surveillance, and also for mobile Satellite- monitoring stations (with a converter for the HF- bands).
It is built into a metal housing.

For this purpose mostly cheap LW/MW- radio receivers were used. It is suspected that the R 880 was too expensive in acquisition, so the cheap radio- solution was preferred.

The front (here in Czech language) has different letterings for each country . For this purpose a screwed on plate is used; behind this plate the front is blank.

The frequency range is devided into four ranges, operated by pushbuttons; The frequency is displayed by LED- numbers. This display can be switched off, to serve energy when battery- operated.

BFO for CW- reception is built-in.

The power supply can be 110 or 220V AC, or 12V DC.

Headphones or loudspeakers can be connected. The middle plug of the 3- pole connector is 12V, for operation of an amplified loudspeaker.

The receiver is designed for 7/24 hour operation.
