You can reduce the AGC threshold voltage by changing the resistor.  It is
simply a voltage divider biasing a pin on an amplifier.

Earl was apparently uncomfortasble going to less than 33K ohms in his
radio's divider and opted to try and change the regulator.  But there is no
reason that I can see that you can't go to less.  In my radio, a value
around 27K is right.

YMMV, mine certainly does!
