Om Power OM4000A

General description and advantages of OM4000A amplifier

The model OM4000A is a auto power amplifier, designed for use on all amateur bands 1.8 -29.7 MHz (including WARC) and all modes.

It has two ceramic tetrode valves FU728F.

The advantages of OM4000A:

 

  • Automatic switching between bands
  • Automatic Tuning with Ribbon according to segments
  • Automatic transfer of band-pass filter
  • Automatic switching of antenna switch
  • The ability to use 2 different antenna within a band or segment
  • Full compatibility with
    • -I COME
    • -YAESU
    • -ELECRAFT
    • -Ten-Tec Orion
    • -Kenwood
    • -Icom transceiver protocol using microHAM output devices-CI-V (MK II, MK2R, MK2R +, etc)
    • -Flex Radio 6xxx series
