I'm going to build an amplifier with around 5x gain to sit between the 11X trainer port output and the ppm input on the rangelink - unless anyone has a better idea?
I believe it is a pulse stream so not an amplifier but a comparator with the reference set at 2v and Vcc at 10v so output swings between 0v and Vcc.
