Has anyone built one of these? Can't find it with search...
I am part of a small group that wants to put up a VHF/UHF repeater. The specs I have been given:
On startup send Morse code ID then start a 10 minute timer. If no activity send Morse Id again.
Waiting for carrier detect. On carrier from receiver, key transmitter and connect audio.
On carrier, start a 3 minute timer which resets on carrier drop. If 3 minutes is up and carrier still active, wait for carrier drop then transmit raspberry tone.
If 10 minute timer up, send Morse on carrier drop.
I have the Morse routine from another repeater setup, but not the timing bits.
I have started but these new-fangled M2 devices are a bit of a challenge. I am looking at interrupts and 'parallel' processing.
