Meeting: "Military HF Radio Communications and Near Vertical Incidence Skywave Propagation”

Speaker: 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.
