AM 1050 is a clear channel frequency. For much of its history, WPQR (previously WBNC) had been a daytimer, required to go off the air at night because of that. Two 50,000–watt stations, CHUM in Toronto and WEPN in New York City, dominate the frequency in New England at night. While WPQR transmitted 1,000 watts by day, it eventually was permitted by the Federal Communications Commission (FCC) to stay on the air at night with 63 watts.
WPQR went dark on October 17, 2012, along with its translator, W237BX. The tourist information format, call letters and FM translator were then transferred to the new station on 1340kHz (then WPQR) which picked up the WBNCcall sign. The translator remained W237BX. WPQR's license was deleted on November 14, 2013, after being surrendered by the licensee on November 6, 2013.
