[Elecraft] K3 - Latest Beta update

[Wayne Burdick]

Terry,

With AGC OFF, your first line of defense is to set CONFIG:AF LIM to  
something in the 18-24 range so that the limiter will jump in to  
protect your ears when a strong signal appears.

The "AF output protection" feature kicks in at a *much* higher level.  
To trigger its muting action, you'd have to inject a very strong  
signal (say S9+50) along with max RF GAIN.

We've had a few reports that this AF muting comes in a little too soon  
in the AGC OFF case, and we'll be updating the firmware soon to move  
this threshold upward.

73,
