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. Ciao de Chuck ti3djt NOTE: I HAVEN'T TRIED OR VERIFIED THIS, PROCEED AT YOUR OWN RISK! WA2ISE A NOTICE FOUND ON A PIECE OF TEST EQUIPMENT MADE IN JAPAN: IT PUT ON THE VINYL SHEET ON THE SURFACE OF UPPER & LOWER PANEL FOR THE PROTECTION PLEASE USE AFTER TEAR OFF VINYL SHEET WHEN USING.
