What
You will see where these observations fit into ham radio, especially for High Frequency Operation. Bill holds several degrees in Geophysics, including a Doctorate in Geo-physics from the Colorado School of Mines. Bill says his discussion will clear up a few misconceptions that have been noted in some ARRL publications.

When
The pre-meeting Elmer session runs 1800-1845 (local U.S. Mountain Time), then the Main Program is from 1900 to the end of the meeting.
