Really unlikely as I said, since comets and planets
are not affected. But hey...

All objects that seem to show the Pioneer
anomaly have something in common: they all
are escaping the solar system with
hyperbolic trajectories.

Ulyses was not, it is orbitting over the Sun's poles.

Planets, asteroids, satellites and comets
in the solar system exhibit elliptical
orbits, so they do not show the Pioneer
anomaly. They are not actually escaping
the solar system.

Maybe.

When an object escapes any gravitational
system, it transfers momentum to the
system.

Not "transfer", "exchange". And it was a one-time transfer to a
planet (in this case).

When an object enters into (it's being
trapped by) a gravitational system, it
gains momentum from the system. These
transactions of momenta *for object
escaping or entering into gravitational
systems seem not to be very well
accounted for by GR or by Newtonian
gravity. This physics must be better
understood.

Agreed.

But until then, anomalous gravitational
Doppler shifts shouldn't be ruled out as
a possible explanation of the Pioneer
anomaly and other 'graviational'
anomalies observed in the solar system.

No one is "ruling them out". Establish a "probability pool", of
causes.

Mechanical causes have been established for 2 of 4 probes that show
this effect.

And mechanical causes will most likely be constant, since internal
temps, instrument power draw, transmitter power, package geometry,
alignment, are all regulated to be constant.

The effect does apparently not vary with distance. So it has no basis
in "gravitation" or "magnetism" as they are defined today.

I only ask you to be likewise open minded on this one. We do need to
look...
