has a DIY that shows how to extract a 10th non proportional channel that is permanently assignedto switch D in the 9Z.
Looking at my 148DP I see it has the same decoder chip and TWO unused pins for channel outputs. All this after I special ordered a new 149DP on 50mhz. Rats.
Oh well. I'll have to change the 9Z name plate to 10Z and the receiver to 150P.
