This is a modernized successor to the R-105dM radio. Its variants for operation on a different frequency range were designated as: R-108M - from 28.5 to 36.5 MHz; R-109M - 21.5 to 28.5 MHz.
Despite the similar name, this is a completely different design, significantly lighter (bakelite casing), built on subminiature tubes and semiconductors. The R-105M was intended for ground forces
