Captain Matthew Sherburne, KF4WZB / US Army Signal Corps
Time: Wednesday, December 4, 7:00 PM -- 8:00 PM
Place: Squires, Mountain Lake Conference Room

Synopsis: HF communications allows us to communicate around the world by
reflecting radio waves off the ionosphere. This mode of communication has
allowed militaries to move farther and faster than ever before at least
until satellite communications were launched. Learn how HF is still a
viable means of voice and data communication for both amateur radio
operators and the military. I will cover the basics of HF radio-wave
propagation followed by a history in military HF communications from WWII
to today. Before communication satellites were launched, Near Vertical
Incidence Skywave (NVIS) was the preferred method for communicating over
mountains and large areas covering a 300-mile radius. I will discuss how
various militaries adapted their vehicles to take advantage of NVIS
communications and the current antennas in use today.
