Yep you are right, it's not a net, just chatting on repeater. I think I confused myself at first thinking it was just local simplex.
I'm sure once I make first GMRS contact things will make a bit more sense.
I'm trying to use https://mygmrs.com/repeater/4438 as it should cover my location. Should be simple enough to reach and use correct tone, but I haven't been able to confirm with contact or squelch tail yet. Will keep trying. I'm just a noob with HT, but having fun.
Thanks for the help
