[Elecraft] OT: Request for EMI/RF Interference Opinion

There's also a website where you can hear what all the new and old digital 
signals sound like.   Sorry, I forgot what it was, but it should be easy 
enough to find.

I'm still wondering what those "weebles" signal are on 10 & 12 meters.  Now 
that I have a waterfall display, they're easy to spot.

They typically start high in frequency and end abruptly, some moving very 
fast and some slowly.

Probably just a Barsoomian invasion fleet.

73, Charlie k3ICH
