[Elecraft] AGC Information Please - Curious

[Lyle Johnson]

You can tap DISP when any of these are displayed and a short help 
message will scroll across the VFO B display.

> AGC HLD (Hold?)

In slow AGC, this is the time that the AGC will hold its most recent 
peak value before starting to decay.

> AGC PLS (Pulse?)

This defines the width of a signal that is considered a pulse (like 
ignition noise) instead of data (like a CW dit).  If a pulse is 
detected, the AGC rapidly decays back to its previous value after the 
pulse ends.  Otherwise, the AGC assumes it was a signal and responds 
accordingly.

> AGC SLP (Slope?)

This allows you to change the "flatness" of the AGC.  Some people like 
ift flat (very strong signals and moderately weak signals all have the 
same loudness).  Others prefer that stronger signals drive the audio 
level alittle harder than weaker signals.

> AGC THR (Threshold?}

Determines the level below which signals do not drive the AGC.

> AGC-F (Fast)

Sets the decay rate of the AGC in Fast mode.

> AGC-S (Slow)

Sets the decay rate of the AGC (after the Hold time) in Slow mode.

> Please use non engineering terms....

The best way to understand what these do is to play with them, adjusting 
one parameter and operating the radio until you are comfortable with 
what that parameter does, then changing another, etc., until you know 
what they all do.  Then adjust them to optimize the K3 for your personal 
preferences.
