One update to this diagram that should be noted is the fact that the PTT resistor should go to ground in order to activate. I imagine this could be done with a single PNP transistor acting as a switch. I’ve toyed around with the idea of make a small IC amplifier and PTT switching circuit for data transmissions. I’ll post it when it comes to fruition.
