[time-nuts] improved WWVB signal being planned?

[beale]

I thought this was interesting... I don't know if this had been already mentioned here- probably some list members are already part of the process!  I wonder if this would be a spread-spectrum code like the GPS signal?

"[...] Another idea being actively investigated is to add phase modulation to the existing WWVB signal while leaving the AM BCD code intact. This would allow all existing devices to continue to work, but allow a new generation of radio-controlled clocks to be developed.  These new devices would have greater processing gain and therefore be capable of reading the time code with a lower signal-to-noise ratio."
