CMARA owns and operates a 2 meter repeater for the local community. The repeater is open for use by all legally licensed amateur radio operators, however, please review the repeater operating procedures before using the repeater. CMARA membership is always encouraged but is not a requirement to use our repeater system.

At present, the repeater is a very old Motorola Micor (1980’s vintage) with an output of about 40W into the filters. CMARA also possesses a newer, never been used before Motorola Quantar repeater system that is ready to replace the Micor whenever it fails due to age.
Much more detail of the repeater, including photos, specifications and a full history, is available from this presentation done about the repeater in February 2022.
