Ham Radio for Arduino

Presented by Leigh L. Klotz, Jr, WA5ZNU


Microcontroller technology has exploded in popularity among ham radio operators. The new generation of single-board microcontrollers is easier than ever to use, bringing together hardware and software for project-building most radio amateurs can easily dive into.With inexpensive microcontroller platforms – such as the popular open-source Arduino board – along with readily available parts, components and accessory boards, the possibilities are limitless: beacon transmitters, keyers, antenna position control, RTTY and digital mode decoders, waterfall displays, and more.

About Leigh

Leigh WA5ZNU is editor of ARRL's new book Ham Radio for Arduino and Picaxe, and an author of and contributor to open-source ham radio software packages such as fldigi and quisk. Leigh has been licensed since age 7, and operates on HF and VHF/UHF.

HF Contest Antennas

DX or Domestic, What's Your Pleasure?

Presented by Dean Straw – N6BV, ARRLRET

For years you've probably heard hams say that for HF DX contests you need high antennas. And for domestic contests (like Sweepstakes) you need low antennas. Is this really true? Are domestic and DX contests really mutually exclusive?

Dean Straw, N6BV retired from ARRL as a Senior Assistant Technical Editor. He will explore in detail the range of elevation angles you need for effective contesting and DXing at all points in the Solar Cycle.

About Dean Straw

Dean was initially licensed in 1959 as WH6DKD and has since held 6 calls over the past 54 years as a licensed Amateur Operator. After attending Yale University for Electronics Engineering, Dean was hired by National Radio Company where he designed SSB and VHF radios. He was in the marine electronics industry for 25 years and eventually moved in to technical marketing.

For the last 15 years, Dean has worked at ARRL Headquarters specializing in antennas, transmission lines and propagation. He was the editor of The ARRL Antenna Book and other books dealing with antennas. As Dean retired in 2008 he noted “Few folks are so blessed by the Good Lord to have combined their work and their hobby together!”

 

September 2013 Club Meeting - "An Introduction to Engineering Fundamentals of Lightning Protection"

An Introduction to Engineering Fundamentals of Lightning Protection - with Historical Notes

Presented by Leon Byerley of Lightning Protection Technology 

Leon Byerley was employed at the Langmuir Laboratory for Atmospheric Research as an undergraduate student at New Mexico Institute of Mining and Technology. Not long after graduation with a B.S. in Chemistry, he was employed by the University of Arizona spinoff company then known as Lightning Location and Protection where he worked as the Engineering Manager for about 10 years. Since 1990, he has worked as an independent consultant for many commercial, industrial and government clients on problems involving lightning safety and lightning protection. As an independent consultant, he has also designed several types of lightning detectors and electric field meters at least two of which are in current production.
