History
WRTI began in 1948 as an AM carrier current station. It was founded by John Roberts, professor emeritus of communications at Temple and long-time anchorman at WFIL-TV (now WPVI-TV). He helped found the School of Communications and Theater at Temple. The call letters stood for "Radio Training Institute." In 1952, the station received an FM transmitter, receiving a full license to cover the FM facility in 1953. After years of serving as a student laboratory, WRTI-AM signed off for good in 1968. WRTI-FM switched from block programming to an all-jazz format in 1969. In late 1997, after Philadelphia's commercial classical music station, WFLN, changed formats, WRTI switched to a dual-format service, providing classical music from 6 AM to 6 PM, and jazz from 6 PM to 6 AMs, except Sunday mornings, when it broadcasts Christian gospel and spiritual music.
Programming
WRTI is a music-intensive public radio service, broadcasting classical music during the day, and jazz at night, and Christian spiritual music on Sunday.
The station features hosts John T.K. Scherch, Melinda Whiting, Greg Bryant, Bob Craig, Joe Patti, I. Robin "Bobbi" Booker, Courtney Blue, Rich Gunning, Mark Pinto, and Mike Bolton. Long-time jazz host Jeff Duperon died on June 17, 2019. He was 66. Mid-day classical music host Bliss Michelson died on March 14, 2021, due to complications from COVID-19 at the age of 71. Debra Lew Harder left the station on September 21, 2021, to become the host of the Metropolitan Opera radio broadcasts.
After a long hiatus, WRTI, in 2013, resumed broadcasting full-length concerts by the Philadelphia Orchestra Sunday afternoon. Recorded each week at the Kimmel Center's Verizon Hall in Center City, this series brings the distinctive sound of the "Fabulous Philadelphians" in performance back to the Delaware Valley airwaves.
WRTI presents in-concert performances of South Jersey's Symphony In C Orchestra, the Chamber Orchestra of Philadelphia, the Philadelphia Youth Orchestra, The Crossing and others, as well as opera performances from the Academy of Vocal Arts, OperaDelaware and the Opera Company of Philadelphia.
WRTI is a network affiliate of NPR, PRI and APM, airing news and arts programming from these networks. Programs include NPR's Newscast Service, From The Top, and SymphonyCast. WRTI is also an affiliate of the WFMT Radio Network, broadcasting a wide range of programming from this Chicago-based syndicator including concert broadcasts from the Chicago Symphony Orchestra, New York Philharmonic, San Francisco Symphony, the Deutsche Welle Festival Concert series, and many more programs and concert series on both the analog FM service and the digital HD2 service.
WRTI is also an affiliate of the Toll Brothers-Metropolitan Opera Radio Network, airing the Met's Saturday Matinee performances live from December through May each year. In the Met's off-season, WRTI broadcasts the American Opera Series from the WFMT Radio Network. This series features performances by the San Francisco, Los Angeles and Houston Grand Operas, as well as the Lyric Opera of Chicago. With these series, WRTI broadcasts a full-length opera every Saturday afternoon. WRTI's Mark Pinto hosts Overture, an opera "pre-game" of sorts, playing opera-based music, Saturday at 12-noon, just before the Saturday Opera Broadcast.
WRTI was known for several popular arts and culture based shows over the years. The multi-award-winning CrossOver, hosted by former classical host Jill Pasternak, explored music as "the universal language." The show, which presented music and conversation with some of the world's greatest artists and personalities, focused not only on classical and jazz, but also music in the periphery of those two art forms. Featured have been Michel Legrand, Rick Braun, Byron Janis, Billy Joel, Eric Whitacre, Marvin Hamlisch, Michael Feinstein, Louis Lortie, Herbie Hancock, Yolanda Kondonassis, Branford Marsalis, Michael Bublé and many more. The show was produced from 1998 until Ms. Pasternak's retirement in 2015. Dr. Jack Buerkle, a member of the Temple University faculty and jazz expert, was co-host until his retirement in 2003.
