OM-Power 4001A Fully Automatic
HF Amplifier
General description and the advantages of the OM4001A amplifier
The OM Power model OM4001A is an automatic power amplifier, designed for use on all short wave amateur bands from 1.8 to 29.7 MHz (including WARC bands) and all modes. It is equipped with a two pieces of ceramic tetrode FU728F.
The advantages of OM4001A:
-
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
- – 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
