Also, just as an FYI, don't forget at if you are North of Line A or East of Line C you cannot contact a foreign station unless as noted in the CFR I would imagine that would include any foreign repeaters. §95.1733 Prohibited GMRS uses. (9) Messages (except emergency messages) to any station in the Amateur Radio Service, to any unauthorized station, or to any foreign station;
Seems to me that problems like these led to the development of organizations like ARRL that popped up back in the day for the Amateur Radio Service. The question of the day is if that’s necessary for GMRS. I personally think that there would be some merit to an organization that focused on GMRS voice and very limited data communication methods and teach basic radio operation. Amateur Radio is pretty beyond basic when you think about it. A basic service like GMRS is pretty nice, and could be even better with a little more organization. It’s worth noting that when the FCC makes rule changes they take organizational input very seriously. MYGMRS.com input was mentioned as justification for rule changes (and for keeping certain things) In the FCC’s last round of rule making for the GMRS Service, right up there with Garmin. Professional and hobby organizations serve a huge purpose and there are probably quite a few users of the service who would be interested in such a thing, and there are probably just as many who don’t give a dang either - but that’s kind of the beauty of it, you don’t have to be an electrical genius to just jump in feet first. GMRS meets many different needs. To those who find it a hobby there are just as many who find it a tool on their farm or a way to call home from the parking lot.
These are pretty cool. Do they work with the mygmrs.com Repeater Linking Bundle? https://shop.mygmrs.com/collections/repeaters-and-accessories/products/repeater-linking-bundle
