  • Notes

  • FM1677 FM Transceiver covering the Land Mobile service VHF bands, 70-85 MHz or 156-174 MHz as used in Australia in 1965.

    Normally supplied pre-set to one of the above bands. By the addition of a crystal switching kit, both transmitter and receiver may be operated on two, three or four adjacent pre-set frequencies in one band.

     Types:   
     FM1677A    70-85 MHz
     FM1677C  156-174 MHz

    Receiver
    Designed for simplex operation, fully transistorised, double conversion, crystal controlled. It employs an FM demodulator and automatic noise muting in the absence of signal. Additionally, it incorporates a filter circuit to limit the reception bandwidth to 30 kHz. Three watts of audio power is available through its 4” speaker.

    25-Watt Transmitter
    Crystal controlled phase modulated, using double wound transformer coupled, valve frequency multipliers with push-pull output. All other stages, the audio pre-amp, differentiator, deviation limiter, integrator amplifier, crystal oscillator and phase modulator are transistorised.
