RE: buddy box setup. (FF9-FF7)
Guys, I turned my hobbyroom upside down and found the FF9 manual last night.
The trainer switch seem to be non-configurable and is allocated to "F". this is good, because "F" is on the left shoulder on my radio (diffrence between FF9 chp & cap)
The configuration seem pretty simple, turn all channels to "func" and activate Trainer mode.
