        I.            MARC Officers and Representatives

A.     Correspondence.

Coordination requests, or other communications, will receive action by the appropriate MARC officer within 30 days. If there are problems handling the request which will require further time, the applicant will receive at least a written acknowledgment of his letter within the 30 day period.

B.     Problem Resolution.

Coordination problems not resolved by the MARC coordinators for any reason shall be referred to the MARC Board of Directors for resolution. The Board may require written documentation from the parties involved or the coordinators as part of a fact-finding process prior to making a decision. Failure to provide the information requested may adversely influence the Board’s decision. Depending upon circumstances, the Board decision may range from a simple recommendation to the revocation of existing coordinations.

C.    Decisions.

Decisions of the Board will be presented to the MARC membership at regular meetings or by mail. If requested, the parties involved may be permitted to present their arguments at a regular meeting in order to allow the MARC membership to become actively involved in the decision-making process.

D.    Suspensions.

The MARC Board of Directors shall be permitted to suspend new coordination requests from any party to a coordination dispute. For this purpose, “party to a coordination dispute” shall include, but not be limited to, any party currently involved in any problem resolution procedure or any party whose current operation is not within the coordination parameters, limits, guidelines, and standards as set forth in MARC STANDARDS.

      II.            Miscellaneous Issues

A.     Duplicate Coverage.

The coordinator shall have the right to deny an application for coordination to any party who already owns or operates a repeater on the same band with the same coverage area as that shown in the application. This rule shall not apply to coordinations in effect at the time of its adoption.

B.     Closed Repeaters.

MARC will not make a determination as to whether or not a repeater is open or closed to access by the end user.

    III.            Trustees and Sponsors

A.     Reporting Changes.

The sponsor shall report any change in the operating parameters of a coordinated repeater system—such as location, antenna height, transmitted power, sponsor, trustee, or mailing address—to MARC as soon as possible. Notification of temporary changes is not required if the change is for a period of less than ten (10) days. The following types of changes will require re-coordination as well as notification:

1.      Moving the location of the repeater a distance of more than five (5) miles from its originally coordinated location.

2.      Raising the antenna more than fifty (50) percent of its presently coordinated height above sea level or height above average terrain, whichever is less.

3.      Increasing the Effective Radiated Power (ERP) by three (3) decibels or more.

Implementing any of these three changes prior to the completion of the re-coordination process may be used as grounds for revocation of the repeater’s coordination.

B.     Annual Operating Report.

It is the responsibility of the repeater trustee to examine and edit as necessary the Technical Data Sheet (TDS) to reflect the operating parameters of the repeater system.  Failure to file the TDS by it’s due date may result in an incorrect or omitted entry in the ARRL repeater directory.  Failure to file a TDS for two consecutive years may result in the loss of co-ordination.  The loss of co-ordination will be preceded by a certified letter of intent to revoke the repeater’s co-ordination.  A 30-day response period will be allowed.  The frequency pair thereafter may then be made available for other co-ordination.

C.    Sponsor Coordination.

The sponsor is the holder of the coordination. If the trustee and the sponsor are different, the trustee is designated the representative of the repeater to MARC. All mail will be directed to the trustee at the address that he designates. Notification of a change of trustee may be made by the sponsor.

D.    MARC Inquiries.

Each trustee shall respond with answers to the inquiries of MARC concerning any coordinated system for which he is designated as trustee. Any trustee may volunteer his services to MARC and is encouraged to do so.

E.     Interference.

When a trustee experiences interference, he is to collect valid interference data, as defined in MARC STANDARDS, and attempt to resolve the conflict with the trustee of the other system before requesting negotiation assistance from MARC.
