Dr. J. Michael Dunlap, K7MYU

Ham station of K7MYU

Dr. J. Michael Dunlap, K7MYU invites you to be a sun worshiper. This talk will discuss the nature of our sun, its cycles and perturbations. We will discuss the 22 year sun cycle, ways of measuring the sun's output, coronal holes, the coronal mass ejection, solar flares, and sun spots. The talk will identify how these factors affect the ionosphere and atmospheric propagation of radio signals. The talk goes on to identify the A and K indexes and their relationship to the earth's geomagnetic field. The talk concludes with the impacts the sun has on amateur radio propagation. If you want to understand propagation and roughly predict it, this is the talk for you.

Dr. Dunlap has a Ph.D. in Computer Science. He taught CS at the University of Oregon and Willamette University for nearly twenty years. The last five years of his career was at Hewlett Packard where he served as an engineer and ultimately, the Test Scientist for the LaserJet test lab. He has been a ham for over 55 years. His primary interest is in DXing, CW, teaching ham classes, and elmering younger operators. He is Vice President of the Voice of Idaho Amateur Radio Club.
