  Sb: speeding up Uniden 2510 AGC

  For those of you who are using a Uniden 2510 for packet, you can
  speed up AGC speed considerably, just by removing the AGC SSB switch
  transistor Q-111 This transistor switches the AGC off for CW
  operation, and on for SSB operation.  All I did was remove it and my
  radio now works with very good speed on 10m.  You may put a switch
  between the pads that were for collector and ground.  When you want slow
  AGC turn the switch ON pulling line to ground.  For fast agc turn
  switch off leaving line floating.  That is all there is to it.

  The description of the mod for the 2510 may work for the 2600.
  Those who have the Uniden 2600 may find that the AGC is the same for this
  radio. Look for NJM2902 IC (this is the AGC amp), you may find a
  transistor connected thru a RC network, to pin 12 of said ic. Remove
  also.  (this mod not tested!)
