Hi David, >If you are considering something for "the rest of the company" you could save yourself a lot of bother by getting something like the LeoNTP box: I know Leobodnar stuff, mostly encoders for flight simulator's Garmin navigator(https://www.thingiverse.com/thing:4019943). Their GPSDO is well known option for O100 sat comms, it comes handy when you need also *that* 25MHz reference for improving stability of the LNB for OSCAR100 ham sat transceivers.
Made of Unoubtanium, as almost any kind of item at the moment in Italy. From bricks to cars, wait time is up to two years. Anyway, given that I fear we don't have any NTP server at the moment(not to mention no Stratum 1), I would end up to be responsible for its operation, so a COTS solution is absolutely a good idea. COTS I would like something like one, for example (on backorder as everything): https://www.netburner.com/products/network-time-server/pk70-ex-ntp-network-t ime-server/ Probably we should implement NTPSec for a somewhat serious usage though. I will fiddle in *my* lab with Raspberrys, leaving to ops the joy of being responsible of the NTP infrastructure of the company. We are aiming for ISO17025 accreditation, but we are involved in cybersecurity, nominally for IoT, not for metrology or material testing. Time accuracy is for records, documents and so on. Of course, we need a small electronic bench with the usual stuff, like DSO, DMM and the like, a good GPSDO is a must today, but we don't need periodic calibration. Hopefully any chinesium re-encased trimble should work for this.

Good luck in finding one, though, due to the current component shortage. 73, David GM8ARV -- SatSignal Software - Quality software for you Web: https://www.satsignal.eu Email: david-tay...@blueyonder.co.uk Twitter: @gm8arv _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there.
