The MAARS repeater is located 1 1/2 miles south of Manhattan on K-177. The antenna is positioned 135 feet up on the KSDB tower. The input frequency is 147.855 MHz, and the output frequency is 147.255 MHz. The repeater's call is KSØMAN. The repeater is an open repeater, and may be accessed by any properly-licensed amateur, but the repeater does currently require a PL/CTCSS tone of 88.5.

An autopatch (automated telephone line link) is incorporated into the repeater. The autopatch has open access to all amateurs. Special autodial numbers are available to club members in good standing. NO BUSINESS may be conducted on either the repeater or via the autopatch.

Only amateurs with technician class and above licenses may access the repeater. Unlicensed persons may participate in amateur radio comunications, provided a control operator identifies at the begining and end of transmission, and is present and continuously monitors and supervises the communication to insure compliance with the rules.

Mike, NØPVU, is the official trustee of the MAARS repeater. All suggestions or comments concerning the repeater should submitted in writing by mail or email to Mike.

The autopatch is to be used in the few instances in which a phone is not available (i.e. mobile, emergency, etc.), and should not be used as a replacement for a landline. If you're near a phone, use it instead. Autopatch calls to law enforcement agencies SHOULD ONLY BE USED IN AN EMERGENCY.
