Welcome to T-MARC

T-MARC, The Mid-Atlantic Repeater Council, is a volunteer organization that coordinates Amateur Radio repeater systems to efficiently utilize the allocated repeater spectrum. Through this coordination, T-MARC helps the repeater community to reduce the potential for interference under normal operating conditions.

Additionally, T-MARC develops suggested band plans that allow for users of different modes and emissions to operate in a shared environment with a minimal amount of interference.

The area of T-MARC's responsibility includes the District of Columbia, Delaware, Maryland, Northern Virginia and the eastern panhandle of West Virginia. T-MARC also collaborates with frequency coordinating organizations in the adjacent areas including Pennsylvania, New Jersey, West Virginia and central/southern Virginia to ensure that repeater system operations between those geographic areas can reasonably coexist with repeater system coordinations offered by T-MARC.
