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

[Bob McGraw K4TAX]

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.

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.
