The number of ticks emitted PER ROTATION OF THE EARTH by a clock at the top of
a tower is the same and the number received PER ROTATION OF THE EARTH at bottom
of the tower.

The 'frequency' of a photon (intrinsic wavecrests arriving per second) is
higher at the bottom of the tower than at the top due to the photon's increase
in speed.
The PR experiment fully supports this.
