    R108: receiver with continuous tuning from 20 to 27.9 MHz FM. simple conversion superheterodyne circuit and frequency modulation. power supplied via the power inside the receiver 12 VDC (PP-281 GRC) 24V (PP-282 GRC) apparatus 1 RT 66: transceiver 20 to 27.9 MHz, continuous tuning, output power: Low 2, High 16 W FM 80 preset channels. Receiver Crystal controlled frequency-modulated double-frequency conversion and a frequency modulated transmitter using an antenna comune.Alimentazione supplied from 12 V (PP-109 GR) 24 VDC (PP-112 GR) that provides all the voltages required.

    RT 70: continuous line transceiver 47 to 54.4 MHz, output power: 0.5 w superheterodyne receiver frequency modulated dual frequency conversion, and a transmitter that uses a frequency modulation circuit 'antenna in common. AM-65 amplifier for intercom intercom system function in the radio station, as an amplifier to listen to the outputs of the two auxiliary transceivers and receiver (detailed manual TM - 115039).
    Base MT GR-297 base support and connection of all systems of the various complexes described in the manual TM 11-284.
