There was something wrong with the power connection on the back of the IC-706MKIIG. Power would sometimes cut in an out, usually when I was driving over bumpy roads. I pulled the cable off and noticed that the pins were bent out of shape. The pins in the connector (cup shaped) were spread too far out and were not making solid contact with the pins on the back of the radio. I had replacement pins, so I yanked each of the old pins from the connector (no easy doing) and soldered on the new pins, slid them into the connector, used the tip of a pair of needle nose pliers to lock them into place. I placed the the power connector back on the rig in the truck and it works great!
