[Boatanchors] Beckman 905B WWV Receiver

[J. Forster]

Propagation delays only matter for time transfer. Only the variability of
propagation delays are of concern when calibrating time interval.

The propagation quality can be seen by using an X-Y scope display. The
figure jitter is propagation. And secular shape changes are frequency
difference.
