[RFI] Possible Solar inverter issue

[Dave (NK7Z)]

Hi Mike,

You may want to look over some notes I have on taking a site survey of 
your RFI at:

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

This is a two part article on setting up and visualizing your RFI 
environment.

I also have a presentation under "Presentations", covering steps you may 
need to take in reporting the RFI to get it corrected...

See: NK7Z.NET, and under the menu, look at presentations...

We must reject the idea that every time a law's broken, society is 
guilty rather than the lawbreaker. It is time to restore the American 
precept that each individual is accountable for his actions.
