Thanks for getting back to me.
Pin 3/Orange writing 1 to pin 12 will raise voltage to 4.22v
PTT light goes on
Pin 3/Orange writing 0 to pin 12 will lower voltage to 3.6mv
PTT light goes off
Removing the cable I think is PTT on the radio side and touching the ground on the DRAWS side (Pin 5) results in open transmit until removed.
New Development: If I have radio and DRAWS connected properly I can turn on PTT with CLI. When I turn off PTT at CLI, DRAWS PTT light goes out, THEN if I touch something to the PTT it adds enough resistance to pull the circuit down and turn off the radio.
So I tried some resistors in-line:
1.0k = Too Much PTT wouldn't open
820 = Close, works, but not very reliably
570 = Too Little PTT wouldn't close
outside of that, I'm either out of ideas or parts.
`gpio -g write 12 1 && sleep 1 && gpio -g write 12 0`
Any thoughts are welcome?
