Propagation delay doesn't affect anything on the reference output side of
the GPSDO. The phase of the reference oscillator can vary -- the
synthesizer doesn't care about the phase of the reference oscillator, only
the frequency. Likewise, the VCO output isn't synchronized in any way to
the reference oscillator as far as phase goes.

Well, yeah, I know what propagation delay is, but I don't see where the
phase of the reference has an effect on anything. Are you thinking that the
transmitter's RF carrier needs to be launched with phase coherence at each
site?
