gr-qc/0102103 is worth a look

I believe that analysis may be incomplete.

I would say simplified

What I believe has been overlooked in gr-qc/0102103
is there will be an "expansion of space", notably
of the distance between the Earth and the craft in
accordance with the usual cosmological scale factor
a(t) during the time the signals are in flight.

As above

I'm not up to handling GR but taking a macroscopic
view, I think the end result of the above should be
close to 2*H*v which is much larger than the range
value given in the above paper but still about four
orders smaller than the observed anomaly. It would
be interesting to know if that 'educated guess'
works out.

gr-qc/0402024

[2] This is the opposite of the normal convention
as speeds away from Earth are treated as positive
by JPL but cause a reduction in received frequency.

This is frequently the case.
