I look forward to getting more information from those of you who are working on tracking the phase of the new WWVB signal. I will be writing it up as soon as a design (or designs) are solid. In terms of XOs there are now TCXOs out there that are specified to hold 25ppb. OCXOs may become historical artifacts in time, Or they may just get better specs.
