I'm new to GMRS... Actually haven't bought my first radio yet. I used CB radios back in the 70s. Not really new to radios. However, this is a step up from CB and a little below the level of Ham (Some might say a lot below, I get it)...And I am coms officer for CAP Squadron. Is there a written prodigal for using/Broadcasting GMRS? I hope it's nothing like " breaker 19 this is the rubber duck".... Or spit in the back and yell hello like Andy Griffith in " no Time for Sergeants". You just key up and start talking? I'm kind of a stickler for rules so I want to make sure I understand this system and how to use it properly.
