There are many ham radio clubs around the world. When you become a member of a local ham club, you would be considered a club ham radio operator. There are clubs that have a repeater that they own and/or maintain. The club would have it's own call sign with the repeater.

The radio operating frequencies are NOT related to the RT-CRC1 controller. You can adjust the frequencies of the 2 connected handheld radios to any channels.
