Here is an interesting situation. On 80 meters (3.980 MHZ) the background noise goes from S7 to S9+20 when I plug the KPA500 into the AC outlet. I have not turned on the Amplifier, just plugged it into the AC outlet. I disconnect the power cord from the amplifier at the amplifier and the noise remains. I unplug the power cord and the background noise drops back to S7. This only happens on 80 meters. I have an idea the outlet may have a grounding problem. I will test it tomorrow. Any ideas??
I have a ground bar that all of the radios are attached to. Single ground wire to an 8 ft ground rod just outside the shack. Hmmmmm!
