General:
Radios used by the GDR :R-350M, R-353, R-354, and R-394KM are spyradios. Being HF radios, they cover up to 1000 km. All radios have a high speed morse device. The resulting short emitting time made the tracking of agents more difficult.
The radios mostly were parachuted to their destined place.

  R-354
is a clandestine radio.
It was issued in the 70s. Even though transistor radios were common in these days, the Russians kept using miniature tubes- only the keying device and the transverter were built using transistors.
Lettering is cyrillic. (R-354's predecessor, R-353 had english lettering).
