Here is my situation. I am pretty sure noise is from switching power supplies. Unfortunately, it tends to put noise right where I don't want it. Like bottom of 160, 80 and 40m. Typically the noise is 20-25 kHz of S8-9. One hears modulations on it and the whole band moves up and down in frequency 15-25 kHz over many hours. Best way to locate, inside house, outside house and correct?????
