Are you sure about that? I have a feeling that gravitational frequency shifting is exactly the same effect as gravitational time dilation, and that they both become significant at the same point and for the same reason. The frequency shifting can be thought of as the effect of gravitational time dilation on successive peaks of the EM wave. That is, 1/frequency is effected the same as successive signals. But I never studied general relativity formally, and I might be wrong.
