Tim K4RA presents VHF/UHF digital modes. This presentation covers the basics of D-STAR, DMR, and C4FM/System Fusion. It's a broad overview (i.e., an inch deep and a mile wide) discussing the pluses and minuses of each format without getting into the weeds of how to program the different types of radios (each is different). He also explains how we connect the different digital formats together with a Mega site and how hot spots are used. This presentation helps members evaluate which digital radio will help them get on the air.
