rats@cbnewsc.cb.att.com writes about he Bearcat 760XLT scanner:
 
 I decreased  the  hysteresis  in  my  Uniden/Bearcat  760xlt
 squelch circuit like I did in the 800xlt.  I replaced R58, a
 22,000 surface mount resistor, with a 1 megohm resistor.
 One side of R58 connects to pin 14 of  IC2,  the  same  3359
 chip  used  int  the  Uniden  800xlt.  The other side of R58
 connects to both the wiper of the squelch  pot  (VR551)  and
 VR1, the board-mountsquelch limit adjustment pot.
