OK, I built my ghetto Tx with an Arduino Pro Mini @ 3v3 and get no output from it.
Built one of Zitron's boards as a Tx and get no output from it.
Checking with one of Zitron's boards as an Rx and running the Spectrum Analyzer software, I see nothing from either of the above boards.
Using my OpenLRS module, I see a nice fat signal on the Spec An software.
My Tx is a Futaba T9C (FF9).
I scoped the PPM module pin and see nearly no signal output on my ghetto board or Zitron's board, but, with my OpenLRS module installed I see 2.3 volts on the 'scope.
So, how do we 'trick' the Futaba T9C into outputting a PPM voltage??
So near and yet so far!!
