In preparation for the ARRL Frequency Measuring Test, yesterday Daun
(N8ASB) and I set up our gear for a practice session. We were working
just after sunset here in Dayton, but before sunset at the WWV site in
Boulder.
I took some screenshots of the WWV carrier showing how much frequency
variation took place due to propagation effects. There was almost a
Hertz of frequency shift over a half hour or so period.
I put the screenshots at http://www.febo.com/time-freq/hf/index.html.
