You could also try moving the GFCI to the panel box by installing a GFCI breaker in the panel box and replacing the GFCI outlet with a normal one. This might solve the problem by increasing the distance between the RFI source and the breaker. Also the shielding provided by the panel box may help.
Of course this assumes you do not have anything on the circuit which you would not want GFCI for (like lights, smoke detectors etc.) Lou W2ROW John Shadle wrote > > Hi all, > I realize that this is tangentially related to Elecraft gear since I'm > using a K3 and experiencing this issue, but I thought someone else may > have some knowledge to share with me to help me solve my problem. > > Recently I stopped using a 25' long extension cord to power my > computer, power supply, and other accessories and installed a 2 gang > box directly off of the main electrical panel, where my shack happens > to be (in the basement).
