[time-nuts] WWVB BPSK patent status

[Mike Harpe]

>From my reading of the archives and research it appears that the design for
a BPSK WWVB receiver probably has a patent conflict.

Isn't this a rehash of the old Heathkit patent on radio clocks that held
back their adoption for years?

I have begun work on a BPSK receiver for WWVB using an FPGA.

Someone should look into why the NIST did this at all since the receiver
design got a patent slapped on it right away.
