2M Repeater Sites MARC operates three local amateur repeaters and two APRS digipeaters in the Montgomery County area. These are "open" repeaters and are available to any licensed ham. Our 2m [146 MHz] repeater's main transmitting and receiving site is located in Rockville, MD with several remote sites providing enhanced and extended coverage within the area. The fully configured 146.955 repeater constellation consists of 5 sites and contains 13 antennas!

Our 70cm [442 MHz], D-STAR [444 MHz] and 6m [53 MHz] repeaters operate as single-site repeaters from their respective sites.

2M Repeater Coverage Map  
Our working radius is approximately 40 miles [64km] (terrain limited) providing 5,000 square miles [12,000 sq km] of coverage. The remote sites provide over 500 square miles of "sweet spot" [1,200 sq km] coverage where you are no further than 6 miles [10km] from one of our antennas. In these areas, HTs and low power operation are the norm.
