    Tell us about that. How do you do it?

    Probably using his phone as a mobile hotspot and then synching over the Internet.

    I use this software to sync to a USB GPS/GLONASS rcvr ... millisecond accuracy read once a day. Automatic. No internet, no WiFi involved. $14. (Actually, I bought my rcvrs for $8 but waited a month for delivery.)

    Apologize again for the excessive accuracy and that I am not using WWV or CHU, but (again) what do you expect for cheap?

    Yes. Exactly.

    I only have a Allstar node that needs to have the correct time for the Voice Time announcements.

    I never did the FT thing. It sounds like a "Hello, Good-bye" mode for contesting. o_O

    The good news is this thread offers a number of choices for time sync. Pick the one that works best for you.

    There are a bunch of programs out there that can synchronize a Windows PC (assuming you're running Windows) to an attached GPS dongle. One has been linked to here already.

    If you run Linux, you just need to install gpsd and configure the system NTP client to use gpsd as a time source.

    Mac, I don't know, but there is probably a non-free port of gpsd that the high priest of the walled garden has determined you have his esteemed permission to run.

    I made my own GPS based NTP server out an Arduino. Due to the lack of network propagation issues it’s better than NIST servers are over the internet.

    I have a Leo Bodnar GPS reference oscillator for my test equipment as well. Good stuff for the money.
