Some WW motors create a lot of RF hash and some don't.

If you find what works, let me know. I had a *bunch* of Cormorants decide 
mine was a good place to roost. I gained new respect for the boom, elements, 
and truss for that C3i 7L 6-meter beam.  Too bad they aren't around any 
more.

I'll have to try and find the photos of those guys setting up there.
