[RFI] Does anyone recognize this RFI?

[Dave Cole]

Here is a blog entry I created on locating RFI-- that is your real task...

https://www.nk7z.net/i-have-rfi-now-what-locating-it/


It does not cover how to DF using loops, but it does give an overview... 
  Also see:

https://www.nk7z.net/sdr-rfi-survey-p1/

Which covers how to set up and use an SDR to help in all of this...

73, and thanks,
