Naaa, the REAL arguments are about antennas!
Also got a mobile unit for offroad, but didn't find many people to talk with. But around home we have three good repeaters, so plenty to do. I also got repeater-capable handhelds for camping use, and also use one at the home w/ a base antenna positioned in the room for best reception.
I don’t know of a single introductory thread here. If anything you’ll be permanently scarred by the arguments about what kinds of radios are best and whether a roger beep portends the end of the world as we know it, but it’s actually a pretty fun bunch of people.
Some of the best introduction to gmrs is in the form of Notarubicon videos on YouTube, although you will also want to pay attention to some of the people here to hear some reasoned differing opinions. In particular, look for his GMRS for Dummies video.
Don’t let anyone tell you your radio isn’t good enough. Eventually something someone says may sound like that, but don’t take it personally. You’ll quickly learn what’s good enough for your own needs.
