[Skimmertalk] Anybody recognize this qrm signature

[Pete Smith]

Bill, W9OL - I think if I were you I would use some sort of panadapter - 
either software or hardware - to determine whether it recurs, and, if 
so, at what intervals.  If you can see that sort of a pattern, then it 
is very likely a switching power supply.  Trouble is, it could be 
anything, almost.  If it is, then I'd start by shutting down circuits in 
your house - I found one like this that turned out to be the power 
supply in one of my shack computers.
