[RFI] Anyone have a guess as to the source of this noise?

[AA5CT]

In the "olde  days", Jim, we would tune across the band
and note any similar buzzes at xx kHz apart IF indeed we
could find any more 'buzzes'. With powerline arcs,
the spectra is continuous, there are no discrete 'buzzes'
every xx kHz as with a switching power supply working
at say 48 kHz. Anyway, once this short search is done,
a mental picture (in the mind) is assembled, which can 
then be passed along to others using words in print.

The most useful "picture" of RF noise is a spectrum and waterfall, at 
least 200 kHz wide. Wider views can also be quite useful. Study NK7Z's 
website.
