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.
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.
