OM4001A Manual link.


The OM4001A linear amplifier is designed for all short wave amateur bands from 1.8 to 29 MHz (including WARC – bands ) and all modes. It is equipped with two FU-728F ceramic tetrodes.

 

The advantages of the OM4001A:

  • Automatic band switching
  • Automatic tuning by band segments
  • Automatic switching of band pass filters
  • Automatic switching of the antenna selector
  • 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
      • - 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

LAN Connection

Power amplifier is interfaced to LAN via XPORT made by Lantronix (type XP1001000-05R). More info can be found at www.lantronix.com .

Default factory settings of XPORT are:

IP address: 192.168.1.222

Mask: 255.255.255.0

Gateway: 192.168.1.1

These are strictly default settings. You can modify any of these by going to XPORT web GUI via your web browser. We do not recommend changing any other parameters of the XPORT interface as loss of communication can be caused by doing so. There is no default username or password. It is highly recommended to secure web interface with username and password.

For remote control and monitoring over LAN special software is needed. It is available free of charge, it can be downloaded from the following address:
