Hi all,
I'm planning on converting my KO Propo EX10 Helios radio to use Frsky DIY module. This radio was originally FM via a module interface, currently it has an original 2.4Ghz spektrum module in it.
I'm pretty sure I've identified the PPM signal, V+ ,gnd from the module pins (I delved inside identified the RF pin, measured V+/gnd, so that leaves PPM) - how I can't seem to get any feedback from the pins using a piezo speaker?? Any Ideas?
Note I've done two conversions already and the piezo gave clear PPM feedback on those radios (I converted a Turnigy 9x to Frysky, and converted an old Esky FM to 2.4G with the old module from the 9X).
Thanks,
Pete.
