1. Coordination Standards.
1. Coverage radius and protection radius figures for the coordination classes are as follows:

Class of Repeater	Coverage Radius	Protection Radius
SNPR	15 miles	none
Local	15 miles	25 miles
District	25 miles	40 miles
Regional	40 miles	55 miles
Quadrant	55 miles	70 miles

1. In all cases, regardless of power output or ERP, the repeater�s transmitter is to be configured so that the transmitter�s physical coverage radius does not exceed the repeater�s coordinated coverage radius.
2. Remote receivers shall be configured so that their coverage area lies within the coordinated coverage area of the repeater.
3. Exceeding the coverage radius limits can be cause for revocation of the station�s coordination.
4. All new coordinations will include a 25 mile separation from adjacent channel coordinations.
5. All new coordinations, except SNPR class, will be greater than 120 miles from any existing coordinated co-channel repeaters. (This is reciprocal for any new out-of-state repeaters per Great Lakes Council meeting September 1989.)

   To better serve the amateur community and to better utilize our amateur spectrum. As of April 2, 1996 all new repeater coordinations must cover a min coverage of 10 miles radius. Existing repeaters must have a minimum coverage of 10 miles radius by April 2, 1997 excluding snappers. If a repeater system cannot accrue a minimum coverage the council will re-evaluate the system for re-allocation.

2. Shared Non-Protected Repeater (SNPR) coordination class.
1. Maximum ERP permitted shall be 15 watts.
2. CTCSS access is required and the specific tone shall be assigned by the appropriate coordinator.
3. Frequency pairs are as follows:
1. 144 MHz band: 147.50/146.50 (1 pair)
2. 222 MHz band: 222.38/223.98 (1 pair)
3. 440 MHz band: 440.50/445.50 (1 pair)
4. Any attempt to evolve to a larger coverage radius will result in de-coordination of the repeater.
5. Trustees and sponsors agree to accept co-channel and adjacent channel interference from other repeaters provided that those other repeaters are being operated in accordance with their coordination parameters.
6. Where interference is being caused to any non-SNPR system, it shall be the responsibility of the SNPR trustee to work with the appropriate coordinator to resolve the problem.
7. Although no out-of-state communication is required to coordinate a SNPR, care must be taken to avoid creating an interference problem with existing out-of-state operations.
3. No new coordinations will be allowed in the Local coordination class.
4. Quadrant coordination class.
1. To receive Quadrant status, the trustee must document the potential to achieve the requested coverage radius through submission of Height Above Average Terrain calculations, detailed descriptions of future station equipment, a system map, evidence of detailed terrain analysis, and end-user need, as approved by the membership.
2. To maintain Quadrant status, the applicant must document that coverage of the coordinated coverage radius does in fact exist. This will be accomplished with annual submission of an operational report, a coverage radius map, an updated system diagram, and evidence of user need, as approved by the membership.
5. The standard for testing the repeater�s coverage radius shall be a mobile station with a center roof-mounted antenna with an ERP of 25 watts. This can be a 25 watt radio with a quarter-wave antenna or a 15 watt radio with a 5/8 wave antenna. Using this equipment, a mobile station is inside a repeater receiver�s coverage radius if the system is receiving the mobile station at least an 80% copy 100% of the time. Inversely, for testing repeater transmitters, a mobile station using a 5/8 wave antenna is inside a repeater transmitter coverage radius if the mobile station is receiving the repeater�s transmitter at least an 80% copy 100% of the time. All tests should be made at average terrain during non-enhanced band conditions.
6. Any coordinated repeater operating within its coordination parameters at the time of adoption of these standards shall be grandfathered at those parameters.
1. If updates (from the system sponsor) are not received a minimum of ONCE PER TWO YEARS, the (M.A.R.C.) Coordinator MAY WITHDRAW THE COORDINATION AUTHORIZATION.
2. When a determination has been made, by means of research (to be documented by the Frequency Coordinator) that a frequency pair has not been in use for sixty days, the Frequency Coordinator will send an inquiry by certified mail, return receipt requested, to the trustee and sponsor of record. Should no response be received within thirty days from the date of receipt of this letter, or if the letter be returned as not deliverable, the coordination of the frequency pair will be rescinded. If the trustee responds within thirty days, in writing to the coordinator and the chairman of M.A.R.C., requesting that the coordination be maintained, at the discretion of the Board, any further action may be stayed for up to ninety days.
3. If the repeater is moved more than 5 miles from the original location without notification to the M.A.R.C. coordinator and chairman, COORDINATION IS AUTOMATICALLY WITHDRAWN.
4. In the event of the sale of a coordinated repeater, the coordination of the repeater will have a temporary status for the period of 60 days, UNTIL THE SELLER RELINQUISHES THE FREQUENCY COORDINATION IN WRITING (sent to the frequency coordinator and chairman by U.S.P.S. mail, and the buyer agrees to all of the coordination guidelines, and the unmodified coordination has been approved by the coordinator. IF THESE TERMS CANNOT BE MUTUALLY AGREED UPON BY ALL PARTIES, THE COORDINATION WILL BE CONSIDERED VOID.
5. (Holders of frequency coordination, IE: sponsors and trustees) who terminate their coordination as a result of the sale or transfer of their system, or for other reasons with the intent not to resume such operation shall notify the Coordinator and Chairman of the termination within 30 days of the cessation of the operation and the surrender of the frequency involved. The Coordinator will then entertain requests for eligible applicants for the use of the frequency, IN THE BEST INTERESTS OF AMATEUR RADIO AND THE PUBLIC SERVICE.
2. Band Plans.
   1. All band plans shall be in accordance with the ARRL recommended band plans as listed in the ARRL Repeater Directory, 1989-90 edition, except as noted below. Non-standard pairs or offsets will not be coordinated.
