RaRa Academy

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.

While within the COVID restrictions, RaRa Academy is now RaRa Online Academy!
