Hmm... maybe I could build a 1pps GPSDO based on light flashes from nearby towers, then. No need for my own GPS antenna!

- mjevans 1y agoYou'd probably have better timekeeping from a reasonably connected Pi with a common NTP daemon (take your pick, some are easier to configure / query), and a realtime-ish thread to emit your PPS signal on a GPIO or similar. Probably more robust than line of sight, and able to pool with other NTP servers in your home-lab (and beyond).
- geerlingguy 1y agoTrue, but I'm not thinking of a practical method, just fun. I already have GPS derived time here, but that's been reliable and boring!
