Hands-On Learning Academy learning sessions help support STEM and ham radio at the same time by providing hands on examples for various topics. RaRa Academy provides workshops on a variety of Ham Radio topics and interests. Workshops have included APRS, Power Supplies, HF Operations, Raspberry Pi, Arduino, Digital communications, IRLP, Echo LInk, WinLink, Fox Hunting, build a 20m and 15m fan dipole, 2 meter tape measure Yagi, just to mention a few. For more information contact our education coordinator at academcy@rochesterham.org. Sessions are generally two hours, usually on a Saturday each month at a location described below. 2021 Upcoming Academies Topics: ► Antenna Modeling Part 1 — October 8th 10AM to 12PM (online) Our RaRa Academy sessions are back. One of our favorite topics for both RaRa Academy and Elmers’ Corner are antennas. A great way to understand antennas is to simulate them. Four session will be offered hands-on class about antenna modelling with the 4NEC2 antenna modeler and optimizer software. Topics: – Building 20m HF Dipole in 4NEC2 and analyzing results – Introduction to using Variables and their power in 4NEC2 – Building an HF 20m quarter wave antenna elevated antenna with four elevated radials All sessions will be held online, using Zoom. More details will be published once they become available. If you want a head start, you can download 4NEC2 here: Presenter: Mike Sanchez KM2B Register by emailing education@rochesterham.org ► Antenna Modeling Part 2 — November 12th 10AM to 12PM (online) ► Antenna Modeling Part 3 — December 10th 10AM to 12PM (online) Past Academies (note below this index the sessions are in chronological order)
