The station also provides multiple live streams from its website, currently operating 32 kbit/s and 128 kbit/s MP3 streams as well as an Ogg stream, which can be received throughout the world via the Internet. C89.5 unveiled a major redesign of its website in March 25, 2018. Other upgrades include a real-time playlist and searchable database of the music that is heard on C89.5. History KNHC went on the air as a very low power AM station, broadcasting with 100 milliwatts on 1210 kHz, in December 1969. Fairly quickly, however, the high school moved to build an FM station. In September 1970, KNHC received its FM construction permit and went on the air in January 1971. The transmitter was located at Wedgwood Elementary School, and the station broadcast with 10 watts, covering about a 5-mile circle in the north end of Seattle. In September 1972, the station increased its power to 320 watts, and three months later, stereo broadcasts began. A second power increase, in November 1974, increased the ERP to 1,500 watts directional. In December 1977, a HEW/NTIA grant created a sister studio at Cleveland High School on Beacon Hill. At the same time, the Mass Communications magnet school program at Hale begins, including courses in radio, television, journalism, photography, and graphic arts. Hence the station's call letters K - (U.S. broadcast stations west of the Mississippi), NH - (Nathan Hale H.S.) and C - (Cleveland H.S.). KNHC's format entering the 1980s featured light rock and pop music, with specialty shows in the evenings and on weekends, including jazz and classical. After yet another power increase to 3 kW, this time non-directional, in October 1981, the station overhauled its format the next year to R&B and urban, prompting an increase in listenership. The "C89" name entered use in 1983. New technologies were also deployed; in 1984, a satellite dish was added to receive the urban-oriented Sheridan Broadcasting Networks (an antecedent to today's American Urban Radio Networks), and in 1987, a microwave studio-transmitter link was brought into use along with a new and more efficient antenna. One of the primary challenges in the 1980s was an application filed in December 1983 by the Jack Straw Memorial Foundation and its station, KRAB (now KNDD), to share time with KNHC. The commercial station, which had been facing financial difficulties, set up a noncommercial foundation with the goal of
