Anybody know of anything fitting that description that you might want to deploy in a data center as a Stratum 1? If such a creature exists I shall contrive to get my lunch hooks on one and write a driver for it.That would be fantastic. I mentioned it on Freenode when it first came out - but it may have escaped your attention. :) An eBay search for "EverSet ES100 WWVB BPSK Phase Modulation Receiver Kit" should prove fruitful. I have one - but I haven't had time to tinker with it yet. The kit comes with the double-antenna setup that appears to be key to the improved reception. In the clocks, the antennas are at 90 degrees relative to each other.
Alas. In concept, that is extremely interesting. But a bit too bare-metal for me; first I'd have to recruit help to design and build it into something one of my computers can talk to. OTOH, I have written successful I2C code; if something like this hardware were a Raspberry Pi HAT I'd have bought one before I finished typing this reply and probably have a test system up in 24 hours. So it's close. Real close. Relevant link: https://www.ntpsec.org/white-papers/stratum-1-microserver-howto/ It would be delightful to add a WWVB radio version of the build to that document. -- <a href="http://www.catb.org/~esr/">Eric S.
