I had a situation with an older (analog) power supply (that had its negative side grounded to the main AC ground) that tripped the Ground Fault Circuit Interrupter (GFCI) in one of the bathrooms. Eliminating the bond to ground fixed the problem. And, NO there was no problem with high SWR, RFI, etc. on the rig or antenna. It was a new house, it only happened on the whirlpool tub circuit, and since I did not use it that often It took months to determine that use of the transmitter was causing the problem - It tripped off while I was on air and the tub was in use. Only the tub used that circuit, so there was no indication other than it not working after filling up the tub and turning it on. It was a cheap GFI, and I can only assume that a transistor/diode in it was rectifying the signal on the ground line and tripping the circuit. -- View this message in context: http://n2.nabble.com/Grounding-negative-side-of-power-supply-tp4424150p4424658.html Sent from the [OT] mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
