Amongst all available wire-antenna options, the vertical full-wave loop (vFWL) has established itself as an excellent performer in terms of efficiency, gain, and take-off angle (TOA). However, full realization of these considerable advantages are accompanied by size, geometry, and height requirements that become increasingly daunting as we progress to lower frequencies. Accordingly, in hopes of …
This presentation gives you a good overview of the World Radiosport Championship and what it takes to be among the top contesters who qualify to participate in the WRTC. It will also cover what it takes to put on such an event while giving you insight into the competition itself. Presenter Bio Bill Lippert, AC0W, …
Amateur radio is entwined with a lot of geospatial data: countries, states, grid squares, positions, parks, and more. In some cases, the map you want to see may already be available. However, in others, the map you are looking for doesn’t exist yet. This session will cover foundational spatial data concepts and how to go …
HamSci is an organization that bands together hams and scientists to learn about the ionosphere and radio propagation. It has been covered in QST, but what does it mean. We will learn how the HamSci network monitors propagation parameters, including magnetic disturbances and time-of-flight signals. Changes in these indicate that the ionosphere is active and …
Microwave signals are easily attenuated by terrain and foliage. Operators interested in microwaves frequently have to operate portably with clear horizons. Flat farm fields over soybeans (not corn) work. Microwave signals propagate beyond line-of-sight, usually by scattering phenomena. From 3 GHz to 24 GHz, water droplets in rain (or snow) are helpful as a scattering …
A review of the past year in Em Comm and Events. We supported probably 20 events and exercises this past year. We will cover best practices and lessons learned. Presenter Bio NY9D is MN Assistant Section Emergency Coordinator for Events. He is also Med Comms lead for the Medtronic Twin Cities Marathon. He is a …
DXing from a Highrise shares N0UK’s experiences of tackling the challenges of operating from an urban apartment residence and proving it is possible to be successful in working other stations around the world. After getting his feet wet for a couple of years on HF, he focused the next 34 years playing on the weak-signal …
Wayne will discuss the role of the state POTA mapping representative, how parks are added, and sometimes deactivated. Wayne will discuss how this is important to the integrity of the POTA program. This is a great opportunity to ask Wayne your questions about how different park entities qualify for inclusion in the POTA program. Presenter …
The ICS Field Observer (FOBS) Essentials program—developed jointly by Minnesota VOAD and Minnesota ARES—addresses one of the most persistent gaps identified in After‑Action Reports across Minnesota: the need for timely, accurate, and actionable field intelligence. As noted in the article, “responders need accurate, timely information to make decisions during floods, storms, and other incidents,” and …
We will talk about how to study for a license, modes of operation such as FM, SSB, digital, Meshtastic, public service, drones, and types of radios. It can be a lifetime hobby full of related hobbies. And shameless promotion of the Richfield Amateur Radio Club. w0rrc.org Speaker Bio Paul KE0QXV passed technician and general class …
