closing this posting no further replies are needed or desired. Got my answer
Well, considering you started this thread yesterday and I don't see much in the way of GMRS related postings from you before that time, I'd say you jumped in pretty quick, wanted access to repeaters, and then gave up all within about 24 hours.
If you are interested in GMRS (and I expect you are, since you invested in a radio and the license), I'd say take a deep breath and a step back.
There's a lot of good info on this site, but it's not always easy to find. You can always ask questions and you'll usually get good advice. GMRS has been around for a very long time, and there's people here that have had their licenses for decades. I had one going back into the early 1990's. There's a bunch of people that tried to help you above, and are probably more than willing to continue to help you.
And YouTube is a resource, but I wouldn't call it a good one. There's a lot of very bad info there. I'd say there's probably more bad info than good info.
A better approach may be to start a new thread. Spell out exactly what your expectations are, and what your needs are. Be open to comments from those with a lot more experience than you. You'll get some good info, I promise.
GMRS is intended for short range family communications. Most people on GMRS want to talk to their family and friends and will use CTCSS/DCS to filter out other users. Repeaters, as mentioned above, are considered private property and not all users are going to welcome outsiders on them. GMRS is not a good resource for random communications like you'll find on amateur radio or CB. It's the wrong tool for the job if that's what you are looking for.
Finding an open repeater, or a repeater owner that will let you use their system takes time and patience. Yes, some repeaters are open to any GMRS user, and are great resources. There is no requirement that a repeater owner respond to your request or give you access to their system. If an owner doesn't respond, move on and look for other opportunities. Maybe there's other repeaters in your area, maybe not. There's nothing to stop you from putting up your own repeater on your own or with the help of other GMRS users.
