WRTIとは 意味・読み方・使い方

WRTI, owned and operated by Temple University, 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'd 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. It added classical music in 1997 after Philadelphia's commercial classical music station, WFLN, changed formats.
