Re: Factory service still available?

I had a strike come in through the buried tv cable. Took out the cable modem, the router, the Ethernet-connected PC (in the shack), and the RS232 connection to the K3. 

Currently, the shack pc connects wirelessly to the internet!

 Most lightning damage I’ve seen comes from the antennas. A good ground and lightening arrestor system is important, but I still leave my antennas disconnected. I also use APC ups and plug strips with a high choke value

It's very possible the USB failure on my K3 IO board was due to lightning, we do get some lightning here occasionally. All of the radio and PC equipment run off a large APC pure sine wave UPS - I was hoping that would isolate my stuff from the AC mains but maybe the UPS is normally in bypass mode until loss of input AC. I wonder if an isolation transformer would be of any benefit?
