1. E-mail the coordinator with your proposed location (lat/lon in DD MM SS format) and your requested band.  See: Degrees, Minutes, Seconds and Decimal Degrees Latitude/Longitude Conversions
2. The coordinator will perform a search for you and indicate available frequencies from which you may select. Be aware that there are no 2 meter pairs available in all except some southern and western areas of the state and 440 pairs in the northern part of the state are running scarce. Also be aware that the this list is preliminary in that while the Alabama data is up to date, data from neighboring states is always dated or in one case nonexistent. You are not guaranteed of that frequency until the NOPC process is complete so don't rush out & buy Crystals and tune Duplexors yet !
3. Once you select a frequency from the coordinator's list, you must submit an application for that frequency which can be downloaded from this site. The coordinator can help you fill in a few parameters using software tools to calculate such things as HAAT (from your supplied coordinates) and ERP from your supplied Tx power, gains & losses but you must fill out the rest of the form in it's entirety. Ask for help if you need it, do not guess as this will delay the process. Be aware that the person listed as "applicant" becomes the "holder of record" HOR. The ARC will only accept future updates from this person so for club oriented repeaters, we recommend the club itself be listed as "applicant / HOR" while an individual is listed as the Trustee and becomes the POC for the ARC. That way, there is not doubt the pair belongs to the club as opposed to an individual and updates can be more easily accomplished.
4. Once the coordinator has your application, it is entered into the ARC database as a "proposed repeater" and an NOPC (Notice of Proposed Coordination) is generated to all neighboring states within 150 miles of the proposed site. We try to "cc" you on this so you'll know where you are in the process.
5. When favorable responses are received from all neighboring states (be patient, this can take 3 or 4 weeks in some cases), the coordinator has some paperwork filing to do and then an "NFC" (Notice of Frequency Coordination) is created and snail mailed to the applicant. This document contains important information regarding conditions under which a repeater must be re coordinated. You must sign and return one copy of the NFC indicating two things before your coordination is complete:

A: That you have actually placed the repeater in the air

B: That you understand the conditions for your coordination to remain current. The ARC normally allows 60 days to place a repeater on the air but extensions are granted regularly - just ask. Above all, keep your contact info with the ARC current including snail mail addresses, e-mail addresses and several phone numbers. Repeaters have been de-coordinated because ARC lost all contact with trustees.

 That's It !
