Radio station R-123M “Magnolia-M”

R-123M “Magnolia-M” – onboard VHF radio station in the range 20.0 – 51.5 MHz

  The radio operates in simplex mode, has a frequency modulation.

  A brief description of the scheme of the radio station:

  The radio station R-123M is assembled according to the transceiver scheme. The operating frequency range of the radio station is divided into two sub-bands: 20.0 – 36.0 MHz and 36.0 – 51.0 MHz. Tuning to the frequency is done with the smooth tuning knob. It is possible to tune the radio station to 4 pre-prepared frequencies (ZCH), with the simultaneous tuning of the antenna matching device. The receiving path of the radio station is assembled according to a superheterodyne circuit. Squelch – by low frequency signal. The matching antenna device has two tunable elements, which are controlled by a single multi-turn knob. The voltage converter for powering the anode circuits is made in a separate housing. The radio was installed mainly on armored vehicles.
