How Repeater Directory Updates Are Made

Updates to the MARC Repeater Directory are made by the organization sponsoring the repeater.

Repeater sponsors designate the individual responsible for communicating updates to MARC (usually the repeater trustee).

Updates are made by submitting an updated TDS / Coordination / Update / Review Form

You can help MARC improve the accuracy of the Repeater Directory.

If information in the repeater directory needs to be updated, please contact the sponsoring organizaton or repeater trustee and ask them to submit an updated TDS form to MARC.

Periodically, MARC will refresh the Repeater Directory with the latest information posted to the MARC repeater data base.

Delinquent Repeater Directory Entries

Trustees associated with entries appearing in RED ITALICS  need to submit a TDS update for those entries.  These entries are considered to be in a delinquent reporting status.  All repeaters must be updated at least every two (2) years, or face possible loss of coordinated status.

NOTE:  Repeaters with a * preceding the call sign are being prepared for De-Coordination.

Final submissions to the ARRL Directory will only contain current TDS data that is complete and has been processed and approved by MARC.   The only exeption will be repeaters that have a current TDS on file with MARC, that are waiting to be posted to the MARC database due to administrative procedures.   These entries will remain in red italics until their last TDS Date has been updated in the database.

The update reporting deadline for having your repeater(s) listed in the ARRL Repeater Directory is December 31 of each year.  This does not mean you have to update every year.  It means your updates must be current, or less than two years old, in order to be listed in the ARRL Repeater Directory.  Updates received after December 31 may or may not be included in the Repeater Directory the following year.
