K3 in a CW pileup - version 3

[Dave Hachadorian]

Here is an improved method for keeping loud pileups in the linear
gain region of the K3, improving copy.  This method takes
advantage of the recently-discussed fact that K3 overall gain is
reduced when you turn AGC OFF.

1. Dedicate an F-Key in your logging program to turn off agc
whenever a loud pileup shows up.  Turn it off on both rigs if you
are so2r.  In N1MM, the macro is:
{CAT1ASC SWH027;}{CAT2ASC SWH027;}

2. Add to the "exchange" message a command to turn fast agc back
on (for both rigs in so2r). In N1MM, the macro is:
{CAT1ASC GT002;}{CAT2ASC GT002;}


The effect of the above is that agc is turned off, and gain is
reduced, only while you are struggling to pick a callsign out of
a loud pileup.  As soon as you send the exchange, fast agc is
restored, and gain goes back up on both rigs.

I don't EVER use fast AGC in a contest. It makes things hard to copy.  I
always use slow AGC set to its fastest setting, that's long enough to keep
the loud bauds linearly loud, and short enough to recover when the loud
station gets worked.     73, Guy.
