This may be a fool's errand, but just in case - I have discovered relatively pure carriers every 8 KHz 2-28 MHz (not heard on 160), tapering in strength as the frequencies get higher.  I assume some

If they are pure and stable I would not assume a power supply, most of them are wide and drifty. Pure carriers are more likely a computer, tv, or other electronic device source. Most switching suppli

Pete, As I recall you may be a Hi-Z user. If you are hearing these spurs on a Hi-Z array you may want to check all the elements. If one gets shorted or partially shorted to ground we have had cases w

These are characteristics that typically identify a switch-mode power supply. 1. The noise is not uniform across an amateur band, but has peaks that occur every N kHz, with N typically being between
