|Instructions for completing repeater coordination
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
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 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
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
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
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.
