LAN Connection
Power amplifier is interfaced to LAN via XPORT made by Lantronix (type XP1001000-05R). More info can be found atwww.lantronix.com .
Default factory settings of XPORT are:
IP address: 192.168.1.211
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 address:

NEWS @ HAM RADIO FHN 2016: OME POWER “OM2000A”
OM POWER is introducing a 2KW (2.3 KW max CW output) HF+50 MHz Amp to compete with ACOMs 2000A amplifier: The OM2000A. A totally truly automatic amplifier (self-tuning) with total remote control by software. Probably the first high power amp with an ethernet connector (TCPIP addreseable) on the back. VERY promising.
“Rolf, KE1Y, has a EFHW 80 – 10 and it’s wire has broken near the loading coil. He wants to know if there is a better way to have the loading coil so it would be so likely to break and Dave’s view of the EFHW.” Read more
