The Enhanced WWVB signal has better range and more accuracy, but I don't know if any receivers are available yet.

A note on using a Raspberry Pi as a NTP server. In my limited home lab
testing the RPi server had enough instability that Internet time sources
were always preferred by my workstation after ntpd had been running for a
while. Presumably this was due to the RPi's clock frequency drifting. At
some point I will look at it again.
If you do want to build your own Stratum 1 server you might want to glance
and the references there.
I had hoped to use the very low cost RPi Stratum 1 servers at $DAY_JOB, but
the test device was clearly not up to the job. At some point I hope to
revisit this and do some more testing like I did for that poster. I'll add
in a CDMA server and a dedicated WWVB receiver.
