  • Model: AN/ARC-502 VHF Radio Set for Aircraft - MILITARY U.S. different makers
  • Shape
  • Boatanchor (heavy military or commercial set >20 kg).
  • Notes
  • Airborne radio transmitter/receiver equipment for 24 crystal controlled channels in the 100 - 156 MHz VHF band. AM modulated at 8 W rf output. Based on AN/ARC-3 system , the radio set has been extended from 8 to 24 channels to suit the requirements of the R.C.A.F. (Royal Canadian Air Force).
    With 3 additional relays in RX and TX resp., 3 crystal banks of 8 crystals each can be selected. As a consequence, new crystal holders were required that keep 24 crystals of smaller sized CR-18 rather than CR-1 as being used in the original ARC-3 system.

    The radio set comprises the following items:
    R-5009/ARC-502 Receiver
    T-5015/ARC-502 Transmitter
    J-5007/ARC-502 Power Junction Box with Dynamotors DY-21/ARC-3 and DY-22/ARC-3
    C-5037/ARC-502 Control Panel
