High Quality Content by WIKIPEDIA articles! WGBH (89.7 FM MHz) is a public radio station located in Boston, Massachusetts. WGBH is a member station of NPR and PRI. The license-holder is the WGBH Educational Foundation, which also owns WGBH-TV and WGBX-TV. The station, dubbed "Boston's NPR Station", broadcasts a news-and-information format during the daytime (including NPR News programs and PRI's The World, which is a co-production of WGBH, PRI, and the BBC World Service), and jazz music during the nighttime. "GBH" stands for Great Blue Hill, the location of WGBH's FM transmitter, as well as the original location of WGBH-TV's transmitter. Great Blue Hill in Milton, Massachusetts, has an elevation of 635 feet (193 m), is located within the Blue Hills Reservation, and is the highest point in the Boston area. (The late Mai Cramer, longtime host of the program Blues After Hours, jokingly maintained that the station's call sign stands for "We Got Blues Here!".)
