Looking somewhat deeper into the mystery, I chose to look closer, not at my antenna and ground, but at the BC band itself. Using my Icon R75 and RxPlus software, I made a band scan of the BC activity. What I found was most troubling for my location. The plot below shows a screen capture of the scan. Clearly KGOW stands out 2 to 3 times stronger than any other local station. It dominates the scene and saturates my post. More disturbingly, it takes the joy out of the hobby. Mercifully, my handy dandy wave trap goes a long way to solve much of the trouble, but not far enough. I need to direct my efforts in trapping this station now.
Question: Is this spectrum normal? Is it common for one station to so dominate the scene? I sometimes wonder if they arent cheating on their power output there. I know, probably not. My next project may be finding a way to use this energy to charge my batteries or light my house, or heck, to power my radios! The following plot shows that while by day I am merely in trouble, at night things are near hopeless. The band scan is a night spectrum. Sad thing is, I don't partictularily care to listen to sports on radio, (or television for that matter).
