General description and the advantages of the OM3001A amplifier
The automatic linear amplifier OM3001A is designed for all shortwave amateur bands from 1.8 to 29.7 MHz (including WARC bands) and all modes. It is equipped with a two pieces of ceramic tetrodes 4CX1500B.
The advantages of OM3001A:
-
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

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 user name 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 link: Remote control software version 3.41.
NOTE: For the correct functioning of the software, it is necessary to have accessible LAN ports 9999 and 10001.
