I don't see it being that good because I think the path of the radio waves it receives could be off by that amount, but I have not caught it in perceptible error listening to WWV directly. Using that and one of those electronic digital stop watches along with multiple split time checks might get you fairly close. That deflection is interesting, as I live about 70 miles east of the Rockies myself. I would think the calculated azimuth would be affected too, more so closer to noon. Thanks for giving that web site so I can give it a try. -- Richard ...
