Visualizing VHF/UHF Propagation with Radio Mobile

Presented by Bill, AB7AA

Keystone

This presentation will focus primarily on interpretation of the VHF/UHF propagation coverage maps produced by the Radio Mobile computer program and how they can be used to estimate antenna gain, height, and power requirements for reliable FM service between mobile and fixed units.  OVARC repeater coverage maps have been uploaded to the clubs web site for user reference and repeater selection for required coverage.  The presentation will review the propagation methods used as well as their capabilities and limitations, however, the discussion will be limited primarily to concepts introduced on the Technician Class license exam.  As a minimum, this presentation should offer a visualization of VHF/UHF Propagation and why it differs from strictly optical line-of-sight.  Setup and execution of the program will not be covered, but for those interested in running the program, Bill offers a list of both text and video tutorials.

Bill was first licensed in 1965 and has held his present call (AB7AA) since upgrading to Amateur Extra in 1993. He spent his college years as a broadcast and studio recording engineer in commercial AM/FM/TV stations while receiving an undergraduate degree in Mathematics with Physics minor, and then did graduate studies in Systems Engineering. After college he spent a career flying various fighter aircraft while developing, evaluating, and teaching electronic warfare systems and tactics. He achieved the position of squadron commander in the Air National Guard A-7D Fighter Weapons School and helped initiate the F-16A Fighter Weapons School. After retiring, he had a second career as a commercial airline pilot.

Does anyone really know what time it is?

Presented by Frank, K4FMH 

Its about timeTIME. . .It’s perhaps the most significant ingredient in our daily lives and it’s relationship to ham radio is huge. Coordinated Universal Time is known to most of us but time is found right inside our own radios. Come and listen to Frank, K4FMH who will talk about TIME and its influence on Amateur Radio.

Frank, K4FMH is a Professor Emeritus at Mississippi State University, Adjunct Professor at Emory University, and Editor-in-Chief with Springer Media, a large scientific publisher in The Netherlands. He was a Senior Policy Analyst at the Board of Regents of the University System of Georgia in Atlanta after retiring from MSU. After a 50 year wait, he was licensed at Ga Tech as Technician and General in successive months. He built two radio stations in Milledgeville GA while finishing college during the early 1970s (WXGC, WXLX; both with different calls now), holding a 3rd Class FCC Broadcast License. Frank served as Asst. Director, Delta Division, ARRL, President of the Magnolia Amateur Radio Club in Starkville and Vice President of the Central MS Amateur Radio Association in Brandon MS. He has been a member of the Atlanta Radio Club since 2010. He was able to get his Senator, Roger Wicker, to submit the Amateur Radio Parity Act during the last two Congressional terms. Frank’s interests include both rag-chewing and experimentation but love to learn new technologies in amateur radio.
