Welcome to the web site of the
Arizona Repeater Owners Frequency Coordination Committee
a subcommittee of the
Amateur Radio Council of Arizona

We interface with and cooperate with adjacent state certified coordinators for all near border coordinations.

Thanks to everyone who sent comments on the modified band plan proposal. Here is an update:

Why would we mess with something that has been in place for many years?

The main reason is to preserve spectrum. Secondarily to streamline the job of coordination. (Remember, we are volunteers with jobs and families.) There are many frequencies that are not available because of another pair on the reverse. This same issue makes coordination much more difficult because of the number of scenarios that need to be checked. We proposed some changes and updates to the current band plan, but some of these had more of a negative effect than positive. Luckily, many in the amateur community spotted issues that either were not addressed or where the changes might cause problems.

So, for now, we will remain on the current band plan until such time as a better solution that is workable for all (at least most) can be found.

The Frequency Coordination Committee of the Amateur Radio Council of Arizona is a group of volunteer amateur radio operators who work to provide coordination services to the amateur radio community in Arizona. Coordination is performed for vhf and uhf frequencies to be used for repeater, digital and point to point operations. This service is available for amateur radio frequencies from 29 MHz and up.

The chairperson of the committee is appointed by the ARCA membership and is ratified by the repeater owners at their annual meeting each July at the Williams hamfest. The chairperson of the committee then choses the remainder of the coordinators.
Coordination policies are also made or revised at the repeater owners meeting.

The FCC gives preference to coordinated repeaters in interference situations (part 97.205), so it is to the advantage of anyone wishing to construct a repeater in the Amateur Radio Service to avail him or herself of the work of a NFCC certified coordinator serving the area where the repeater will be located.

The Frequency Coordination Committee of the Amateur Radio Council of Arizona is a charter member of the NFCC (The National Frequency Coordinator's Council)
