Kinda sucks all the good 'backup' methods of time keeping are dwindling.
I've got a WWVB clock as well that I'd love to get hooked into my main
NTP server, but I worry they're going to finally kill that off in the
next year or so.
LORAN C clocks still have potential to work well too...
High accuracy time keeping is a fun hobby. :)

I looked before at who had spectrum allocations in the frequencies my

was deployed on that frequency. IIRC, both US Cellular and Verizon had
basic CDMA running in my area on those channels. Sprint was running LTE
and 1x Advanced (or something like that), so probably wouldn't have
worked out. If Verizon is dropping theirs, then depending on only one
company seems a bit unwise.... which means I gotta find some kind of
solution by then. *sigh*

There's actually a few other CDMA networks in our area (Boise) besides
Verizon, so it wouldn't hurt to look. I seem to remember Sprint is
planning to go to 2021? There also appears to be a few smaller
independent CDMA networks around as well.
