Community and corporate contributions (often obtained during regular fund drives) have helped the original single station grow over the years into a network of 22 facilities with large primary service contours covering New York's Capital District, Western Massachusetts, southern Vermont, and parts of New Hampshire, Connecticut, Pennsylvania, and New Jersey. WAMC-FM's main transmitter and antenna are atop Mount Greylock in Adams, Massachusetts, the highest mountain in the state in the Mount Greylock State Reservation; it had formerly been a tenant on the tower, which was built and maintained by Albany's ABC affiliate WTEN (channel 10) for their satellite station for the Berkshire region and Pittsfield, WCDC (channel 19; it shut down in 2017). The tower also features a radio facility for the Massachusetts State Police and a translator station for Albany's NBC affiliate, WNYT (channel 13).
