regulations it could and did broadcast commercials and was self-supporting. The station simultaneously provided audio signals of its broadcasts over "dorm line" wires that ran past exterior windows of the MIT dormitories, for residents to connect to their hi-fi gear. An early experiment in stereo broadcasting, in 1960, put one stereo channel on the AM signal and the other on the dorm lines. In the mid-1950s, the possibility of an FM license was explored and it was discovered that the call letters WMIT are in use by a North Carolina station serving the Asheville area. WTBS (for "Technology Broadcasting System") was chosen as the best alternative. New facilities were constructed in the basement of Walker Memorial, including a switching and mixing console designed by A. R. Kent and Barry Blesser, believed to be one of the first all-transistorized consoles ever built. On April 10, 1961, WTBS signed on from a small antenna atop the Walker Memorial Building, which houses its studios, with 14 watts of

at 88.1 megahertz. (This frequency corresponds to a wavelength of 3.40 meters or 2 smoots.) In the early 1970s, the antenna was moved to the much higher Eastgate Apartment Building, dramatically improving the coverage area. WTBS continued to operate the carrier-current system to the dormitories on 640 kHz, with an identical program, except for commercial breaks on the AM side, during which the noncommercial FM station filled time with public-service announcements, and, later, parody "ads" for fictitious products such as "Apple Gunkies" and firms such as "Nocturnal Aviation". The carrier current transmission was discontinued in the early 1970s. The all-request "Nite Owl" was a popular weekend feature, and a "

). Although call letters are not technically for sale, Turner and WTBS worked out a stratagem whereby Turner gave a $25,000 donation to WTBS with an agreement that WTBS would apply for new call letters, with a second donation of $25,000 promised if the FCC were to subsequently grant the letters "WTBS" to Turner. All went as planned, WTBS used the donation for new transmitter equipment, and on November 10, 1979, the station signed on as WMBR (for "Walker Memorial Basement Radio") with 200 watts of power, later increased to 720 watts.History of WMBR
