[Elecraft] K3 AGC Mush ... or "blur"

[David Gilbert]

To be honest, I've never tried that very often.  The one or two times I 
have done so (AGC off, RF Gain at max) have not been pleasant 
experiences.  The only time I get a pileup of weak signals is working 
Europe from here in Arizona, and that means I have to point through some 
very loud signals on the East Coast ... it only takes one of them to 
cross my passband to teach me a lesson.

If I get the chance during the upcoming ARRL 10m contest I'll give it 
another try.  I'll also try to record the entire contest to see if I can 
come up with a decent sound clip.
