I have had this sitting on my USB for a while and just forgot to push it to github. https://github.com/wgaylord/ESP32-Repeater-Controller

It firsts initializes all the needed pins then both radio modules before registering two interrupt routines. 

The interrupt routines are used for detecting when the RX radio gets a signal to trigger the TX radio.

The main loop does a check if its been on for too long. (Someone talking a long time with out unkeying) If this is the case it turns of the TX modules PTT. The next thing it does is the Identification.  I will probably have to add some sort of delay to this but I will figure that out when I have to.

I will be trying to program the module over the next week.
