It may
be that the difference between the real motions and this simplified
assumption is negligible but it is not obvious to me from your brief
remarks.
 Another consideration is that the radiation received in one case may
have been sent directly from the craft and in the other case sent from
the craft after having been relayed from the same earth station. In the
relayed case the speed of light delay ignoring any coding and decoding
delay would have been a only a second more according to the proposed
hypothesis. But possible coding and decoding delay may have changed
things. Your argument does not take this into consideration.

It's always "may" and "might" and "possible" in your arguments. And if your "coding and decoding" argument had any basis in reality the times involved would be completely arbitrary, depending on how the DSN computers handled the data. As I've said before, this is all on file somewhere, and if instantaneous communication was possible they would be using it.
