Instructions for completing repeater coordination form:

Fill in as many blanks as you can. If an item does not apply to your system, insert N/A (not applicable) where appropriate. If necessary, you can give more detailed explanations in the Other Features Section if you want it viewed by everyone including visitors or in the Notes Section at the bottom of the form if it is to be kept confidential. It should be each owner/trustee's goal to complete the form and keep it current so this webside is able to function as it is intended.... The most up-to-date information available..

If your repeater uses more than one set of input/output frequencies, for example it has inputs/outputs on 2 (or more) separate bands, fill out a separate form for each band, and indicate that the systems are linked together on each form. If this form is for and intermediate link system, insert the word "link" in the "Other" block under repeater status, and explain under "Other features" where each end of link terminates. Most link systems are "closed".

Check the appropriate blocks for system features. In some cases, you may need to indicate mixed features, such as an open repeater with a closed autopatch. Be sure you accurately reflect the operational status of your system. This information will be forwarded to ARRL for inclusion in the national repeater directory unless instructed differently. In some cases, you might need to check more than one block on the status line, for example when describing the closed link.

If your system uses CTCSS (PL) tones, please be sure to indicate the tone frequencies, not the "codes" used. If your system uses tone burst access (e.g.: 1800 Hz burst) indicate the appropriate frequency as either a "primary" or "alternate" tone as appropriate, and be sure to include the word "burst". If your system uses LITZ (Long Interval Tone Zero) as alternate access, write in LITZ as either the first or second alternate tone, instead of a tone frequency. Be sure to include the primary PL tone, if used.

If the sponsor is a club or other organization, such as a corporation, indicate the proper name of the sponsoring organization. If the sponsor (owner) is a private individual, give the owners name and call sign.

The information on trustee name, address, and telephone numbers and so on will be kept strictly confidential, but it is important that you provide the coordinator with this data so that you can be contacted quickly in the event of an emergency.

The physical location of the repeater must be specified both as an address, milepost, etc. and as geographical coordinates. Coordinates obtained via a GPS receiver are preferred, but other sources such as topographic maps are acceptable. Coordinates should be entered as degrees/minutes/seconds/as shown. Mileage should be to the closest 1/10 of a mile. Metric unites may be used if specifically identified as such (e.g.: 1.6KM).

The elevation of the repeater can be determined via a GPS receiver (best method), or alternatively by using an accurate topographic map (1:25,000 preferred, other scales may be used with less accuracy). Elevations are given as feet above mean sea level (AMSL).

List the name & city of the nearest airport, and the distance and direction to that airport from your repeater site. Show distance as feet if less than 2 miles, or as miles and tenths if more than 2 miles. List the direction (in degrees) TO the airport From your repeater site. Examples: Merrill Field, Anchorage, 8500Ft., 350 Deg. (or) Fairbanks International, 10.6Mi. 027Deg..

The effective radiated power (ERP) of a repeater can be calculated using standard formulas as found in the ARRL handbook. In brief, you must consider transmitter power in watts, duplexer and feed line losses, and antenna gains when calculating ERP. ERP is always calculated for the strongest lobe of directional systems.

Unless you are using an omni-directional antenna, please indicate the direction (azimuth) of both the main and any known secondary lobes of you system antenna. Antennas mounted on the side of towers always exhibit some offset gain, so be sure to include this in your calculations.

Coverage areas are considered to be those areas where good quality communications can be accomplished with average equipment. Marginal coverage areas and/or those locations where exceptional efforts are required to establish or maintain communications should not be included in your system's normal coverage area.

The method used to control your repeater, in this case, is the PRIMARY method of control. If you have additional control options, list them in the notes section. Direct control means a licensed ham is physically at the repeater location whenever the repeater is in use. Remote (primary) control via radio link is permissible, provided the control link frequencies are above 220 Mhz. Channel control systems (control via the normal main repeater input frequency) are considered alternate (secondary) controls, and require support by a separate primary control system. Dial up telephone control is an acceptable primary control method, and is considered to be "wire line" control. Multiple primary control systems are permissible.

If your repeater uses control systems that traverse multiple radio links, be sure and list the call signs and channel frequencies of each intermediate system.

Coordination is not achieved until a COMPLETED FORM is on file. The completion of the coordination form on this website and keeping the form current is the responsibility of the owner/trustee. A REVIEW of the form needs to be completed between September 1 and December 1 each year to keep coordination current. CHANGES to the form can be administrated at anytime. During the same time frame, if the owner/trustee does not have the capability to operate this website, a form can be requested via mail, fax or phone and returned in the same manner. The coordinator will update this website with any information that is obtained via these sources. Failure to submit the original coordination form or to maintain the form each year may result in loss of coordination and your frequencies could be assigned to another user or group.

Remember, only those systems which are current will be submitted to ARRL for publication unless requested otherwise.
