2021-11-09 – Current status of the HamSCI project – Dr. Nathaniel Frissell Ph.D. W2NAF
Dr. Nathaniel Frissell used simulations based on data from recent solar storms and eclipses to demonstrate that the ionosphere responsible for long-distance high-frequency radio propagation, is not a smooth structure as often depicted in textbooks. Instead, it is highly dynamic and subject to numerous unexplained small-scale spatial and temporal variabilities. Even with the large, professional-grade observational networks that currently exist, the ionospheric system remains undersampled. In his presentation, he explained how the Ham Radio Science Citizen Investigation (HamSCI) is working to design a Personal Space Weather Station (PSWS) that individuals can place in their own backyards, make observations that contribute to the advancement of ionospheric science, and benefit their own personal amateur radio operations.

2019-05-21 – Workshop – Soldering 101 – Dave Adanich K8WDJ
SOLDERING 101 – “Or How Not To Burn Your Fingers”
This Workshop is set up to teach basic soldering techniques that a Ham or any electronic enthusiast can appreciate. Did you know that there is evidence that soldering was employed as early as 5,000 years ago in Mesopotamia? Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. Sumerian swords from 3000 BC were assembled using hard soldering. Soldering was historically used to make jewelry items, cooking ware, and tools, as well as other uses such as in assembling stained glass.
This Workshop, while directed to new hams and beginners in electronics, is also a valuable tool to the “old-timers”. There are many new techniques that will be presented in the hopes that all attendees can leave this Workshop with up-to-date information that will make that new homebrew project or kit worthwhile. I will give a short presentation at the beginning (20 mins +or-) of the Workshop then we will go into some real tabletop soldering projects.
