  • Separate independent receive path based on Direct Down Conversion principle (DDC)
  • Separate independent transmitter, based on the Direct Up Conversion principle (DUC)
  • Full or half-duplex mode *
  • Antenna switch for 2 antennas in HF
  • 10 MHz reference input
  • Built-in power-meter and SWR-meter in HF band
  • 8 open collector outputs for control of antenna switches, band pass filters or other accessories.
  • ALC output for external power amplifier**
  • PTT input for footswitch
  • CW key input
  • Headphones output, impedance 8-10000 Ohm
  • Microphone input for dynamic or electret microphone

    20W may not sound like a big number, but ample of power for day to day traffic. If you need more output, just put a amplifier behind.
    Nice to be able to run 2m with a useful spectrum view in the normally very uncrowded band.
