I should have mentioned that the receivers tx modules and hand held units are spektrum rc equipment not arduino
problem im having is I think the module needs to be in a radio with a active ppm signal for me to bind everything as usual
an easy fix would be to just get 2x radios but that is expencive and bulky to do this thats why I want to simulate the radio to power the modules
I have 2x spektrum sm1000 tx transmitter modules
2x spektrum sr3000 rx surface receivers
2x spektrum handheld telemetry screens
2x spektrun on-board telemetry sensor stations
now as I said before all this stuff usually binds to each other no problems if you have the radio for the module to fit into but I want to eliminate the radio and swap it with a arduino instead
