Matt Callahan Radio Homepage
Welcome to my radio homepage. In addition to computers and programming, my other nerdy hobby is radio. When I was 16, I bought my first scanner from Radio Shack, a Pro-71, and I've been listening ever since. I am a licensed amateur radio operator (K7MFC), a licensed GMRS radio opearator (WRAA720), and I am currently a board member at Arizona GMRS Repeater Club.
But why radios?! We have cell phones in 2019, right? We do, but they don't work everywhere in Arizona. Radio is most useful to me when I'm camping and exploring the Arizona back country, miles away from cell phone service. I monitor state and federal radio communications during wildfire season, and I rely on VHF and UHF two-way radios for off-road mobile communications.
WRAA720 UHF Band Plan
This is my personal band plan for UHF two way radio, used primarily for outdoor recreational activities - 4x4 exploration, camping, fishing, etc. This plan allows for compatability with bubble-pack FRS radios and unlicensed users for short range communications, as well as full power operation on GMRS channels for use with family and other licensed GMRS stations.
