The tiny 13 dollar GPS module has arrived and I have it connected to the progrock. Its working perfectly.
The 2 leds on the GPS pcb indicate data output and 1 pps output. It only outputs 1 pps when its got lock, so perhaps the led could be extended out to the front panel to indictate when its actually sending 1 pps into the pll.
Using BKTtimesync software the data output of the GPS can be used to timesync your laptop, so its worth putting a db9 on the front panel too.
I ran the setup from a couple of LM regulators, 5 volts for the GPS (maximum) and 8 volts for the pll, but 9 volts would be suitable, and it will then run from 11 to 16 volts for portable use.
