Unless the starship varied it's thrust during the voyage in a non-
pre-planned manner (i.e. based on decisions made by the starship crew
enroute). Even that is not too bad, since the starship crew can easily
tell what their shift is relative to Sol (by looking at hydrogen lines
in the sun, or by keeping track of their acceleration), while Earth can
afford to have broad band reciever (to grab the signal from the starship;
Earth meanwhile always broadcasts at a constant frequency, and the
starship can easily calculate the frequency for them to recieve at).
