[Elecraft] AGC threshold

[Guy Olinger K2AV]

I have suggested an AGC setting where the response is linear until a
maximum audio level is reached, where the AGC cuts in flat with with a
slow decay that converts to fast decay over one second.  To set up for
this, turn your audio to your "normal" audio.  Then tune in a very
strong carrier.  Adjust the audio limiter in config to the loudest
tone you want to hear. Use the RF gain/PRE/ATT to get the band ambient
noise at a comfortable level.  For this "contest" AGC, "light" both
the S and F on the display.  I believe this will give the results of
riding RF gain with no AGC, without the blasts.

For myself, the above should be what you should get with AGC in the
off position, but that is another discussion.

73, Guy.
