[RFI] SMPS RFI Hunting

[Charles Plunk]

Great topic Mike. Looking forward to suggestions. Have a switcher on 6m 
right now somewhere, hope its in my house. I have 2x 817 & a tinySA 
also. I have played with the tinySA for hunting these without much luck. 
Always seems better just loop and receiver. My FT-60 HT in AM mode has 
been real handy and really portable for V/U hunting but not spectrum 
display. I adapted the battery packs to lithium for long runs. Also made 
a holder for it on the pvc boom on my 2m tape measure homebrew yagi for 
more portability.
