hello
thanks all for the suggestions, you send me some links to device that will
be useful
Actually i use the station remotely, so no way to disconnect the equipements
First of all I will try WiFi on the computers.
Most of the equipments are bonded to a common ground. I have a copper bar
behind the desk and radios, amplifiers, rotor controllers (RT-21), etc, are
connected to ground
Thinking about it now, I have an internet link. The Ubiquiti antenna at the
farm was burned, then there's a LAN cable to a switch inside the shack
connected to a Netgear switch, it was burned too. Thank LAN cables go to
two computers, Red pitaya, LAN power switch, remoterig
One computer was burned, the other is OK
RedPitaya is OK
LAn power switch had some issues, but still work
Remoterig still work
From the burned computer, USB cables to:
- Green Heron everyware BASE, burned
- 3 x RT-21, need to check USB, but they are working manually
- KPA1500 amplifier, will check today. Is working but I think USB is damaged
Today will return to station, if stop raining, and will continue checking
thigs
