All of the phase tracking receivers no longer work due to the new bpsk wwvb
modulation.
Certainly if you need accuracy any of the GPSDOs out there are better then
the old wwvb receivers.

I have a 599 and will hope that the project I have been working on for far
to long will allow it to track again.
As to the 1310s etc. Never heard of them. Something to search for on the
internet.
