[Elecraft] K3 Dual PB

[Fred Jensen]

I've found that the APF is very sensitive to the multitude of AGC 
settings available.  I haven't actually broken the code yet, but there 
are times an inaudible signal without APF rises to "copyable enough to 
get a Q" with APF.  Other times, not so much.

Just one more way to learn how to use my K3. :-)
