General description and the advantages of the OM3501A amplifier

The automatic linear amplifier OM3501A is designed for all short wave amateur bands from 1.8 to 29 MHz (including WARC – bands) and all modes. It is equipped with a one piece of ceramic tetrode GU78B.

 

The advantages of OM3501A:

  • Full compatibility with TRXs-CAT
    • - 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
    • - Apache Labs Anan
  • RF sensitive Band and Frequency switching, for use with radios which do not have CAT
  • Automatic switching between bands
  • Automatic tuning with the band according to segments
  • Automatic switching of band pass filter – BAND DATA output compatible with YAESU radios (BCD code)
  • Automatic switching of the antenna switches - maximum number of antennas is 10, controlled by BCD output code
  • Remote control via PC Windows Application
