- This is a bit of a puzzle, to me anyway. With my tribander pointed in one direction (west), I have extremely bad what sounds like line noise. This noise is not audible on 20 meters, on 10 meters, o

- Pete, Does your noise remain constant in intensity/signal strength across the 15 meter band? If not, you may have a non-power line source to hunt. If you have an oscilloscope, place its probe across

- Couple of things that will change a noise from what's considered normal. The source of the noise or where the noise is radiating from to get to your antenna could be in a position that allows it to a

- Thanks, Mike - As to your latter point, I think this qualifies as line noise because it is present all across 10, 15 and 20, just at much lower amplitude except on 15, but it certainly could be a res

- Mike, You're statement that it's not likely is correct most the time (99.9%), but there are rare occasions when the hardware configuration doesn't follow the expected weather changes. Had one case wi

- Thanks, Ed - those are good, notable exceptions to the general trend of rain/condensation shorting out the arc path/gap. We have some transformer primary bushings equipped with squirrel guards, but t
