How does that change anything? You declare that time is constant,
which automatically distorts the spatial coordinates to comply
with that requirement. Of course the radiation frequency changes.
You have distorted space time to achieve that end.

This is how the spatial coordinates are distorted for a surface
radius clock and a GPS radius clock scenario (easy to recognize
and fixed with the ECI frame of course). The transmission is
upward from the surface radius clock. If both clocks are deemed
to be running at the same rate, the spatial coordinate in the
up-down direction is distorted according to  1+GM/r/c^2. Which
is 1.0000000006946 to 1 for the surface radius, and
   1.0000000001665 to 1 for the GPS radius. The difference is
5.28e-10 to 1. For each second elapsed, the spatial dimension
between the two has stretched by 5.28e-10 meters, and 4.55e-5
seconds per sidereal day. That's exactly how much the photon
wavelength has been stretched by your time coordinate system.

You distort dimension so that your clock rates are identical,
then claim that this somehow proves that a photon's frequency
decreases, with a wavelength increase as a natural consequence,
as it climbs from a gravity well. ???

No, the former is not what Pound and Rebka implicitly used at
all. In the real world, time and space are inseparable. A spatial
coordinate system produces clock rates that vary with altitude
and that gives the illusion of frequency redshift with altitude.
By declaring that time is constant, spatial dimension changes
proportionally to the clock rate deficit. But nothing has
changed.

or the second image (same image) on the web page
 http://members.optusnet.com.au/maxkeon/redshft2.html
shows the difference. Whichever coordinate system you choose,
they are identical. But need to be specified, as you say.

The very first image on the web page clearly shows that a "photon
wavelength" increase is impossible. From an observation point at
a fixed time rate, the number of waves per second that were
generated at a surface radius and transmitted to a higher
altitude receiver must arrive at the same rate as they were
produced if there is no relative motion between the source and
receiver.

That is a blatantly obvious fact in the spatial dimension, in
which everything exists. Since the time coordinate system is
only a distortion of the spatial dimension the same story unfolds
there as well. Redshifting photon wavelengths can't be squeezed
through that window of "truth" either.
