[RFI] RFI turn out to be a New Solar Panel installed on Roof of Garage 700 feet away from my QTH

[Dave Cole]

An easy way to help differentiate between the two--  if it starts at the 
exact same time each day for the next two weeks, it is more than likely 
a timer, and may indicate a grow operation.  if it follows 
sunup/sundown, then it may be your solar array...

If you look at: http://nk7z.net/sdr-rfi-survey-p1/ you will find a 
method of showing several sources, being able to differentiate between 
those sources, and how to get the start/end times of each source, all in 
one operation.
