Per Bob post below, you don't need the 1PPS with the latest FW. It uses the leading edge of the $GPRMC string. I can provide you an MCU with the latest version he issued. V11-02-10 if you want it. I also have a boatload of Haicom 204III's and GlobalSats BR355 I'm not using (which work just as well, as do several others also per Bob's post below) if you need one. Send me an email
