I have posted before about noise making my use of HF very difficult/impossible at certain times. Briefly, I have eliminated anything on our property as the noise source. the local power company used their sniffer on all of their lines and poles for a mile in every direction from our rural property. I have "sniffed" my closest neighbor's property. The power company rebuilt 3 power poles (all equipment on each pole) because they were emitting "a little" noise. The problem, however, persists and only occurs when the weather is hot and dry. Any moisture at all (rain or high humidity days) and the noise is gone. Can't figure it out as it is 180 degrees opposite of any noise issues I have ever had in the past. Drone overflights (with video) show no solar systems visible within 2 miles of here. Anyone have any ideas? On a no noise day the noise level (all bands and modes) is maybe an S 2. On high noise days it is 10 db over 9 at best. I am not in an urban area with close by neighbors. Very rural with few neighbors the closest (and only) neighbor being 1/4 mile from me.
