Dave,
I have forwarded You a copy manual off the list,
however I am a little surprised when You say that
the connector on the controller is only four
pins. To my knowledge the G800SA and the G800DXA
should use a 6 pin Molex/AMP type plastic plug,
while the G800S and the G800SDX use a 6 pin
Chinch/Jones metallic plug. Are You sure that the
contact has not been replaced? The Yaesu
schematic drawing can be confusing leading people
to belive that only 4 wires are needed.
regards,
