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
