I'm new to GMRS, just got a Retevis RA87 40w for my truck. Looking for some good, solid training resources for programming, antennas 101, best practivces, and essentiall how to go from FNG to semi-pro in a short amount of time. I'm also eyeing the possibility of using GMRS within my town's CERT - does anyone have experience with that, and what pro tips can you share?
