This topic is an interesting one for the reason I operate multiple GMRS and Part 90 VHF and UHF repeaters for our regional SAR Teams. Sometimes something as this can also be a learning tool and educational. Many SAR teams have no clue about radios and buy what a "friend" tells them and its normally a CCR. On my team we have multiple members who have a GMRS license and one of my repeaters is hosted by the team. Team members with the license use this to chat when they want. The repeater is also at a large recreational area and is open to the public. Every radio our team owns has the channel in case of a civilian calling for an emergency. Being we operate on multiple formats in our area the repeater is quiet most of the time. I have found internally the repeater has actually been a good way to get folks to buy the GMRS license as a way to talk to the other members who use it. Lastly as others have said what the sense of having a repeater up with all the costs of a proper install at a tower site just to sit idle. I have invested thousands of dollars on the gear and hope it gets used. If i want privacy we I go to one of my P25 repeaters and run secure if its really important.
