[arm-allstar] How to generate PL

[Max]

I believe if you took a TS64 tone board you could use that for your receive
tone.  Also, you could use your COS signal to turn the tone board on/off on
pin 4.  That way if there were no received signal the board would not
transmit a tone when your repeater ID'ed
