What do you mean by "ensure both CHU and the WWVs are in sync"?

Sync? The American (WWV) and Canadian (CHU) atomic clocks are within
*fractions* of a microsecond of each other.

Why are you making this so difficult and why are you beating it to
death? [...]

Radio propagation within North America is not particularly useful
for accuracies better than 10 ms or so. 3000 km away from your
time station and you have a delay of 3E+06/3E+08 or 1E-02 sec
(E prefixing the power of 10 multiplier here). Of course if you
know you are not receiving via skip you can compensate for path
and get into the submillisecond accuracy range.
