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 sort
of switching power supply, but from what I've read most run at higher
frequencies than that. Is this by chance a signature of a particular
source?
