Resonant ground?

[N1API]

Odd little thing popped up. Have a Kenwood TS-2000 and running HRD using a 'good' FTDI based USB to RS-232 adapter. All works great, except on 10m. Key up and the USB adapter goes unrecognized by the PC. All other bands work fine. Of course when the USB goes unrecognized then HRD stops logging and working with the radio. My guess is a ground issue.

I'm on the second floor of my house. Ran a 14 AWG run of wire for my ground which is about 40' long. Something to research this weekend.

Yep sounds like it's acting more like an antenna. You could try braided wire the larger the better but still may not work. Its there a good electrical ground close by? If there is a good solid electrical ground you could try that.
