For many clubs the repeater *is* the club: it is the shared asset, the daily meeting place and the
+
largest recurring expense. Operating one is a long-term commitment to a site, a license and a budget.
+
For how to use a repeater, see [repeaters](/wiki/operating/repeaters).
+
+
## Coordination
+
+
Frequencies are assigned by a volunteer **frequency coordinator** — a regional or state coordinating
+
body recognized by the amateur community, not by the FCC. Coordination is not legally required, but
+
Part 97 gives a coordinated repeater the advantage in an interference dispute, which in practice
+
makes it essential.
+
+
Expect the coordinator to ask for the site coordinates, antenna height above ground and above average
+
terrain, transmitter power, expected coverage, the license and trustee of record, and your access
+
tone. Keep the coordination record current: coordinators periodically confirm that machines are
+
still on the air, and an unresponsive owner can lose the pair.
+
+
## Site and infrastructure
+
+
- **The site is the hard part.** Commercial towers, water tanks, hospitals, fire stations, grain
+
elevators and county communications sites all host amateur repeaters. Most site owners want a
+
written agreement and a certificate of insurance. See
+
[bylaws and nonprofit status](/wiki/clubs/bylaws-and-nonprofit-status).
+
- **Power and backup.** A repeater on generator or battery backup is worth a great deal to your
+
county's emergency managers, and is often the argument that gets you the site.
+
- **Duplexer and feedline** are not the place to economize; most "the repeater is deaf" complaints
+
trace to tuning, connectors or water in the coax rather than the radio.
+
- **Site noise.** Shared sites are electrically hostile. Desense from a nearby transmitter is the
+
usual cause of a repeater that hears poorly with a full-scale signal a mile away. See
+
[receiver performance](/wiki/technical/receiver-performance).
+
- **Remote access.** Being able to reset, disable or reprogram the machine remotely saves many trips
+
up a mountain in February.
+
+
## Licensing and control
+
+
The repeater is normally licensed under the club call sign, with the trustee named as the responsible
+
party. Automatic control is permitted for repeaters, but a **control operator** must be able to shut
+
the station down promptly, so publish the control operator contacts to your officers rather than
+
burying them in one person's memory. See
+
[club station licenses](/wiki/clubs/club-station-license).
+
+
## Money and access policy
+
+
Write down, before you need it: who pays the site rent and internet, how the club funds a duplexer
+
failure, and whether membership is required to use the machine. Most clubs keep the repeater open to
+
all licensed amateurs and ask for voluntary support; either policy works, but an unwritten one
+
produces arguments.
+
+
## Keeping it useful
+
+
- Publish the frequency, offset, access tone, coverage map and net schedule where a visitor can find
+
them — your website, the national repeater directories and the club's directory listing.
+
- Run at least one **net** on it, so newcomers have a reason and a script for their first
+
transmission. See [running a net](/wiki/clubs/running-a-net).
+
- Decide deliberately about **linking, hotspots and internet gateways** — reflectors, AllStar, IRLP
+
and DMR bridges expand reach but change the character of a local machine, and that is a membership
+
conversation, not just a technical one.
+
- Keep an **asset and maintenance log**: what is installed, when it was serviced, and who holds the
+
keys. Repeaters most often die when the one member who knew all of that stops being available.
