Hi Sege,

I am not sure if you are serious, but this is the day we have for 
jokes in the USA. In case anyone takes that serious, it was not.

The earth could rotate 10,000 miles per second, and there would 
be no doppler effect.

Doppler only occurs when the path length is changing, not when 
the path is moving but staying exactly the same distance.  

It could be more a culture thing, that USA operators listen to lower 
pitched tones more often than JA, or vice versa. But it is definitely 
not earth rotation. Thank goodness, or WWV frequency standards 
would not work, and the AM BC band would be full of heterodynes.
