Sounds like a good job for a PIC. K1EL already has a CW ID PIC (K-ID) for only $6. Unfortunately it lacks the timing needed for repeater IDing & the output is square wave. I used one in one of my portapeaters along with Skipp's favorite IC (555 timer) & a BPF to clean up the square wave. But a PIC should be able to handle the ID interval timing, & a PIC with more outputs could generate an approximated sine wave. The mid- & high-range PICs have built-in serial ports that would make user programming of the callsign, interval, tone freq., etc. easy. Bob NO6B
