Icom IC-761 (IC 761 IC761) activate tuner when in general coverage mod

Remove the top cover of the IC-761 and locate the tuner band switch unit PC Board which is the 2nd small PC board located behind the antenna tuner preset unit.
On the board, locate J 7 and at that location, you will note a three (3) pin molex plug with a black, brown, and red wire connected to it. Either unplug, remove, or clip the center brown wire coming from the plug. Carefully unplugging the wire and placing heat shrink tubing over the end works very well.
This enables the tuner to be activated on GENERAL as well as the ham bands.
