[RFI] weird noise "waves" 60 khz Apaert

[Pete Smith N4ZR]

Today, for the first time, I looked at the bands on the bandscope of my 
RTTY Skimmer Server.  To my surprise, the background noise level shows 
very pronounced maxima every 60 *Kilo*hertx, with a notch next to each 
maximum.  I'm trying to get a screenshot to post, but my Skimmer PC just 
died.  In the meantime, does this ring any bells with anyone.

These are not discrete peaks - more like parabolic shapes repeating 
every 60 KHz, but with significant energy on the upslopes.
