These procedures and guidelines will soon change drastically. Please check back here for details.
Frequency coordination exists for the purpose of reducing or eliminating interference between Amateur Repeaters. In Arkansas, the Arkansas Repeater Council, Inc., (ARC), is the recognized Coordinator.
Frequency Coordination is voluntary. By obtaining coordination, you avail yourself the Protection of the FCC if there is a problem between your repeater and an uncoordinated repeater. The uncoordinated machine is responsible for correcting the problem, not you.
The ARC adheres to Regional (MACC) and National (NFCC) standards of coordination. This requires working with other states to prevent interference to everyone. Since the different organizations are voluntary, not everybody replies promptly. The ARC tries to provide coordination within a sixty-day time frame. This time frame starts from the date of receipt by the Coordinator, till responses from surrounding states that are affected by the coordination and notification is sent back to the repeater owner or trustee. If a coordination response is not received, the coordinator advises the state involved that the coordination is proceeding without their input.
Proper completion of the application form speeds up the coordinating process. If there is a change in the application during the coordination, the new information should be submitted as soon as possible to the coordinator. After the coordination is completed and the repeater is on the air, ANY change in the operating parameters (transmit power, antenna height, ERP, location or frequency) outside the published specifications, the coordination is automatically void and the frequency will be returned to the pool for reassignment.
Deviation limits are as follows: Power - No more than 5 watts from coordinated power (at duplexer output) Ant. Height - No more than +50 ft. from coordinated height ERP - 300 Watts maximum Location - Not more than 1 mile in any direction from coordinated location Frequency - No changes without re-coordination
If a frequency is not used or has stopped being used, the coordination will be voided 15 days after receipt of notification to the repeater owner or trustee that this action will be taken unless the repeater is put back into service. This action insures that frequencies remain available as much as possible.
After a constuction permit has been issued by the coordinator, the applicant has 180 days to complete the repeater installation and notify the coordinator that the repeater is operational, after which the coordinator will issue a Completion Notice. If problems arise and more than 180 days are required, then the coordinator must be notified to request an extension of 60 days.
Coordination is voluntary and depends on you to help keep interference to a minimum. When interference occurs between two coordinated repeaters, the ARC will work with all parties involved to try and resolve the problem to everyone's satisfaction. The FCC has final jurisdiction on any and all complaints.
The ARC charges a minimal fee for coordination to offset mailing and telephone charges. The non-refundable fee is $10.00. ARC Members pay $5.00 Currently, fees for coordination have been suspended unless the Council Funds drop below a pre-set level.
If for some reason coordination cannot be provided at the time of submission, the application will be held for two years. If a frequency become available within that time, the application will be processed with no additional cost.
