Andre VE3WZW came to explain how and why amateurs are flocking to use the DMR digital mode. Being an open protocol with many extremely low cost radios makes this an attractive mode to many. In fact, a group of NSARC members have begun exploring DMR together to learn and build a new DMR repeater for the club.
Additionally, Joe VE3VGJ gave a quick presentation on some elevation research he did. Turns out, the earth is even less flat than you think it is. In fact, short distances of only a few dozen kilometers experience the earth’s curvature blocking line of sight up to many hundreds of feet.
