After 9 months of phone calls and complaints, PG&E finally came out this week and "fixed" the two power poles that were causing most of my powerline noise problems. I say "fixed" because it is too ea

About 15 years ago, I ran into something very similar, except that it was on 80M. Same asymmetrical frequency distribution, in particular, but in my case there were two peaks, one at about 3515 and o

Spark gap exciting a length of wire that just happens to be resonant on a bad frequency. If its outside the frequency can drift with temperature and humidity, and if the wire isn't real tight also in

I have a question. I when I transmit on 40M I turn on my CD player deck. I have to keep all the system power on an outlet strip so I can turn off all power to the system. My audio system is located o

My problem is not that interference in the normal way we think of interference. I do not hear my signal in the speakers nor does it seem to affect the system while it is playing, The only effect I ha
