Superrock KYOI

Superrock KYOI was a short-wave radio station located at Saipan island in the Pacific region from 1982 to 1989. The station broadcast rock and pop music to China, Japan, USSR, Australia, New Zealand, and other countries.

History

The station began transmitting 17 December 1982. Initial frequencies were 11900, 15190, 15405, and 9670 kHz. To promote a new standard of broadcasting, Superrock KYOI had a carefully selected name. "Super" having a very strong, positive meaning in Japan, and "YOI" meaning "good" in Japanese. With the slogan "Super Rock" it was an instant hit not only in the intended target area of Japan, but also, unexpectedly, with listeners worldwide. In December 1986, the Herald Broadcasting division of the Christian Science Monitor Syndicate Inc. purchased KYOI. In 1987, the format of broadcasting of former Superrock KYOI radio station was completely changed. Broadcasts of music programs were completely terminated in 1989 with the station callsign changing to KHBI. In 1998 HBS sold the station to Radio Free Asia.

Technical details

Superrock KYOI was located at Agingan point of Saipan island. Both studio and transmitter facilities were co-sited in the same building, a 2,000-square-foot (190 m²) concrete structure designed to withstand hurricane winds of 150 miles per hour and earthquakes of magnitude 3 on the Richter scale. The entire plant was self-sufficient, with its own 450 kilowatt diesel generator and a 2500-gallon water catchment system with filtering unit and compression tank. The station had a powerful transmitter, a Continental Electronics 418-D-2, 100 kilowatt high level plate modulated, with an automatic servo system, allowing pre-tuning of channels in use. Three tubes sat in tanks of distilled water that boiled off into steam and then condensed back into water to be returned to the system.

The antenna system consisted of a complex and elaborate array, composed of 16 dipoles phased together directed towards an azimuth of 340 degrees true. The program of broadcasting consisted of continuous top 40 rock music controlled primarily by a computer audio sequencing system, with automated song title and station identification announcements inserted as required. The same computer system was also used to change frequency 4 times daily, completely eliminating operator error. The music was run from a program automation system, which held up to seven days of twenty-four hour programming. A time clock was incorporated allowing station IDs and frequency change announcements to be aired at predetermined times. Music, commercials and jingles were all called up from a series of carts also by the computer system.

From its two 170-foot (52 m) towers, the latest in rock music was beamed to a primarily young Japanese audience of 18- to 30-year-olds from one end of Japan to the other. Among major advertisers supporting the station and its programs were Seiko, Sony, and Air Micronesia.

Staff

The main creator of station was Lawrence Berger; other owners were Fred Zeder, and Adrian Perry. The main operator of the KYOI station was the Marcom company. Technical facilities on Saipan employed just six staff, working as operators, antenna riggers and other devices which were needed to keep the station on the air around the clock.

All programs of Superrock KYOI were prepared in Los Angeles, California by the Drake-Chenault Company, and then air-freighted to Saipan. KYOI retained a representative in Japan to advise the programmer of the latest in Japanese pop music trends. Sales of airtime were made in Japan, and bills paid from Honolulu with most business being conducted by telephone and telex.

KYOI received thousands of letters and reception reports, and acknowledged all reports with cards postmarked "Saipan CM". The station also hoped to encourage interest in Saipan as a vacation spot.
