R7000.12 Also from IC-8 pin 19, run a long wire to the front of the unit. This wire will be connected to a switch that can be mounted to the bottom cover. Resolder the lithium battery lead that was disconnected and reinstall the control board and the partition above it. Looking at the bottom cover, you will see two holes near the front. The hole closest to the edge is used to adjust the drag on the tuning knob. The next hole in from the edge is the one you want. Mount a small SPST switch in this hole. I used a small plug and mating connector to make the connections between the switch and the logic board. The long wire that you connected to IC-8 pin 19 goes to one side of the switch and a wire to a ground point goes to the other switch connection. I used one of the mounting screws that hold the remote control board for my ground lead. When you have finished, you will have a second switch selectable bank of memory channels. This also means that you can program in one pair of search limits for each of the two banks of memory. Rich ( K2QG )
