Hi Larry,
That would be good to use 'time synchronized' DFCW (or QRSS) at higher
speeds (well ... 'high' means 3 sec./dot or so). But for 30 sec./dot the
internal PC clock (if set correct) will do the job.
But if there is any interest to use a GPS receiver (or any other timer
source) for synchronisation I am willing to see if I can adapt QRS.

Well if your going this far why not ad real time as an optional alternative?
Connect the INVERTED 1 PPS output from a GPS receiver to the RI line in
RS232 and use the RI interrupt to make the timing coherent to a rather
excellent and free standard available everywhere on this mudball.
RI (Ring Indicate) is available on dB-25 Pin 22, and DB-9 Pin 9.
