[Elecraft] K3s AFSK frequencies

Ed is correct on this, but turning AGC off on the K3 causes 
problems with loud signals due to the hard-limiting and 
distorting action of the AF Limiter.  A better approach with the 
K3 is to use fast AGC,  AGC SLP=0, and AGC THR as high as 
possible without causing a sound card overload warning on the 
loudest signals.  For RTTY, with my usual gain settings, I find 
that AGC THR = 17 works well.
