Howdy from Oklahoma City. I'm a retired truck driver who has used CB radio (legally, of course) for decades. My adult son and I were recently discussing alternate communications for the day when internet and cell phones go dark. My investigations led me to the world of GMRS, something about which I knew nothing until a couple of weeks ago. I sent the FCC $35, and in return they kindly gave me a call sign (WSEG265). A pair of TidRadio TD-H3 GMRS hand held units arrived from Amazon five hours ago. So, here I am, starting from scratch and trying to learn whatever I can about this strange, new world.
