H Chris Sparks(Shelbyville, United States):
According to SRT, the constancy of c falls within a given frame of reference, not across different frames of reference. Within the stationary frame, light propogates at velocity c toward the receiver. But, in a steady moving frame of reference (which includes the moving source), light again propogates at c. When you cross frames of reference you invoke time dilation and length contraction to force equality in an otherwise unbalanced equation. I realize SRT has inconsistencies, but this "trick" doesn't appear to highlight them.
