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 at half its licensed upgraded power from the new transmitter site on December 14, 2011, one day before the construction permit was to expire.[1] The 104.1 translator was sold to MPBN in 2016.[2]
