Premise: Einstein's equivalence principle

Conclusions:
If the speed of light varies with the gravitational potential V in
accordance with Einstein's 1911 equation c'=c(1+V/c^2) given by
Newton's emission theory of light, then the speed of light varies with
the speed of the light source v in accordance with the equation c'=c+v
given again by Newton's emission theory of light, that is, Einstein's
1905 light postulate is false.

If the speed of light varies with the gravitational potential V in
accordance with Einstein's 1915 equation c'=c(1+2V/c^2), then the
speed of light varies with the speed of the light source v in
accordance with the equation c'=c+2v, that is, Einstein's 1905 light
postulate is false.

If the speed of light does not vary with the gravitational potential V
(Einstein would not agree but nowadays silly Einsteinians do teach
so), then the speed of light does not vary with the speed of the light
source v either, that is, Einstein's 1905 light postulate is true.

Premise: The wavelength is determined by the light source and cannot
depend on the movements of the observer.

Premise: (frequency)=(speed of light)/(wavelength)

Conclusion: If the observer is initially at rest relative to but then
starts moving towards the light source, the frequency (Doppler effect)
and THE SPEED OF LIGHT INCREASE.

Compare with John Norton's reasoning (the TEXT IN CAPITALS is wrong):

http://www.pitt.edu/~jdnorton/teaching/HPS_0410/chapters/big_bang/index.html
John Norton: "Here's a light wave and an observer. If the observer
were to hurry towards the source of the light, the observer would now
pass wavecrests more frequently than the resting observer. That would
mean that moving observer would find the frequency of the light to
have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE
BETWEEN CRESTS - TO HAVE DECREASED)."
