There have been several proposals for altering (speeding up) the stock AGC
response of the K1.  The most common is just reducing C31 on the RF board
from 2.2 uF to 1 uF or less.  Some who have the KNB1 noise blanker installed
do likewise with NB C10, though I haven't found that necessary.

Most people find fast AGC to be appropriate for CW operation, so I've been
at a loss to understand why the stock K1 uses such a high value of C31 to
produce such a terribly slow AGC response.

You might want to verify that C31 in your K1 has been changed.
