[RFI] 8-KHZ-spaced low frequency RFI

[Pete Smith N4ZR]

I'm seeing very crisp, clean 8-KHz-spaced RFI spikes on 160 and 80 
meters (on HDSDR).  Because it is clean and does not appear to drift 
noticeably, I'm inclined to rule out switching power supplies.  Any 
ideas what else it might be, to simplify my search?
