Plugged in and it works. I got a few radio checks. They say I sound distant.. of course that varies.. When I turn the RF gain up the noise goes up abit like it should but the RF meter really don't move at all (like the 29).. on the 29 I can go from zilch on the RF meter to about 3db on the meter.. this does nothing like that. So here's the pics of the guts.. I don't see anything jumping out at me. It does have the RCI 8719-A chip.
