Thanks all for your suggestions.
I decided to use subroutines for dit and dah audio frequency and tone length (dit/dah). In main I will just run through my callsign characters calling on subroutines, once it is done ID'ing then run a timer for 10 ~ 15 min between ID's. I guess I was looking at this too closely... I will need to integrate this into my controller code. The repeater TX control passes through the processor and is delayed for 7 seconds after the receive signal COR drops. This eliminates the ker-chunk that you hear from the carrer dropping at the end of a transmission between two parties talking.
