You don't mention the quality of your VCXO. Do you have a part # or else specs i.e. ppm vs temp, time, voltage, etc.
Nice pic btw. And that looks like an OSH Park "gold plated" board. I love their service.

The software is still under development and will eventually include a low-grade GPSDO but right now even the simplistic algorithm is working quite well so I figured I'd share. http://www.eevblog.com/forum/oshw/%27laureline%27-embedded-gps-ntp-server/ This is a low-level microcontroller implementation, there is no OS nor ntpd in the traditional sense. Just enough logic to keep time using the incoming PPS and timestamps, and a tiny VCXO to discipline. It's no Thunderbolt and there is no clock output but it should be fantastic at NTP. Before too long I will have adapters for connecting to Oncore GT+/UT+ (and maybe M12, haven't checked) as well as Trimble Resolution T and Resolution SMT using a ribbon cable instead of the jumper wires. All open-source hardware and software. Pictures, details, and design documents are in the eevblog thread. I'll let you all know if and when I'm ready to sell them, for now I just wanted to show what I've got. -- m. tharp Engineering is the art of making what you want from what you can get at a profit. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
