WMPG originally went on the air as a carrier current station in 1970 before becoming a licensed station in 1973 on 91.1 MHz with 10 watts of power. In 1988, the station upgraded its signal to 1.11 kilowatts and shifted frequency to 90.9 MHz. A 50 watt translator on 104.1 MHz located on Portland’s Munjoy Hill went on the air in 1999.
In 2008, WMPG was granted a construction permit to increase power to 4.5 kilowatts and move transmitting facilities from the Gorham campus of the University of Southern Maine to Blackstrap Mountain in Falmouth. After a lengthy fund-raising effort and a $120,000 US Department of Commerce grant, WMPG started broadcasting from the new transmitter site on December 14, 2011.
Today, WMPG is much more than Southern Maine Community Radio; our reach is global, our 200+ volunteer staff is totally committed, and our diverse programming has never been better!
