[Elecraft] [K2] : Laptop UPS

[WILLIS COOKE]

I don't know if it applies to your situation or not
Raymond, but I had a lot of hum on when I connected my
110V Lap top to my TS-850 for PSK-31.  I had the
charger plugged into a house circuit and my radio
equipment plugged into a separate circuit for the
radio station.  When I moved the charger plug to the
radio circuit the hum went away.
