Product Information
  • Overview
  • Description

The linear amplifier OM2500A is designed for all short wave amateur bands from 1.8 till 29 MHz (including WARC – bands ) and all modes. It is equipped with a ceramic tetrode FU-728F.


The advantages of OM2500A:

  • Automatic switching between bands
  • Automatic tuning with the band according to segments
  • Automatic switching of band pass filter
  • Automatic switching of the antenna switch
  • The possibility to use 2 different antennas within one band or segment
  • Full compatibility with
    • - ICOM
    • - YAESU
    • - ELECRAFT
    • - Ten-Tec Orion
    • - Kenwood
    • - Icom transceive protocol using by microHAM devices –CI-V output (MK II, MK2R, MK2R+, etc)
    • - Flex Radio Series 6xxx
