[Elecraft] Fwd: OT Mystery QRM Help (Video)

[ac5p at sbcglobal.net]

Yes, but David says, "only occurs on 20M", so this may not hear it at 135MHz?   Need portable like KX3 and small mag loop tuned to 20M.

 If one is serious about finding noise, I've found this item to go a long 
way in identifying down to the building or site from which it 
originates.  It takes a bit of practice and time to triangulate but does 
work well.  I'm sure there's other equipment and methods available as well.

This is always a good item for a club to have and own for its members.

> A bit more: I watched this mystery QRM pretty closely for an hour Friday evening as 20 meters closed for the day (by 6:30pm PST). The cadence of this noise changed. It slowed. Then faded away with the band. I’m scratching my brain to try think of a mechanical device that would create that kind of rhythm. And as always as I check 20 meters at 11am Saturday, there is no sign of the QRM.
