old futaba 2 channel 27mhz AM transmitter question
I have an older Futaba FPT-2F transmitter on 27 MHz AM. This is the type that has the big printed circuit board inside. I would like to convert it to 2.4 using a Frsky module. Can anyone help me to find where to solder the ppm and positive and negative voltage leads from the module? I know its just easier to buy a new radio that is modern and has servo reversing but this would be used in a vintage sailboat. Any help would be appreciated. Thanks
