The Calvert Amateur Radio Association operates two repeaters that serve amateurs around the Calvert County area. The 146.985 repeater is located in the northern end of the county in Sunderland, Maryland. The 444.950 repeater is located in the central area of the county in Prince Fredrick, Maryland.
The repeaters can be linked to provide good coverage of Calvert County and the surrounding area. When the repeaters are linked, a transmission from the remote repeater has a two tone courtesy beep following each transmission. A transmission originating through the local repeater will not have the courtesy beep.
The AUXCOMM Net is held each Monday evening following the CARA Net on the 146.985 repeater.
The Digital Net is held on Wednesdays at 7:30 PM on the 146.985 repeater. The purpose of the net is to experiment with the Yaesu System Fusion digital mode, familiarize the operator with their radios, and to have fun on digital.
