Hello Jim,

Something that might help you in your RFI fight is being able to 
accurately define your RFI environment.  See:

http://nk7z.net/sdr-rfi-survey-p1/

for a brief write up on how to use an SDRPlay RSP-1 to look at your 
entire RFI environment, shown as a spectrogram, of frequency vs time, 
across a 24 hour period.

73s and thanks,
Dave
