Who recommends transmit/receive channels for repeater and auxiliary stations?

To prevent repeaters from interfering with one another, frequencies must be carefully planned and assigned. The FCC does not manage these individual repeater frequencies itself; instead, it relies on a self-regulating approach within the amateur community. A Volunteer Frequency Coordinator is an individual or group recognized by local amateur radio operators. They maintain a database of local repeaters and recommend specific transmit and receive channels for new repeaters or auxiliary stations to minimize interference. Options suggesting FCC involvement or ITU coordination are incorrect because repeater coordination is strictly a local, volunteer-led effort.
