Shortwave receiver of Soviet production, entered the equipment of the Polish Army in the early 80s last. Century as thoroughly modernized successor to the R-326 receiver.
It is built exclusively on modern silicon semiconductor devices and integrated circuits. After closing the front cover and the back is fully hermetic, it remains on the water (floating).
