From the very beginning of her ham radio journey, almost 50 years ago, Carol Milazzo, KP4MD, applies the scientific method to her study and enjoyment of amateur radio. Whether she is modeling antennas for installation in her attic or to using WSPRnet to study VHF and UHF propagation, Carol takes meticulous notes, adds footnotes and illustrations, and now produces video. This makes Carol a terrific online Internet Elmer. KP4MD joins Eric, 4Z1UG, on QSO Today.
