What would cause noise spikes at 5khz intervals (perfectly) across an entire spectrum from 160 meters all the way up into 2 meters ?? (and maybe beyond?)
It wasn't there earlier today but when I went to listen this evening, I had squealing noise spikes at 5 khz intervals from the very long wave lengths to the vhf band. (can't check any higher).
This is coming from a G5RV antenna though RG8/U.
I unplugged all the little transformers from the outlets and even tried turning off the CFL and LED lights.. nothing had any affect.
Thought maybe wife was running microwave or something but no.
The spikes are almost all the exact same size on spectrum analyzer display, perfectly spaced at 5 khz.. When getting to the 10 meter and 6 meter band, they start to change a bit where every other spike will be 1/2 the size.. but perfectly spaced at 5khz.
I didn't see this during the day... any ideas?
