KOIT-FM
KOIT (96.5 FM) is a commercial adult contemporary radio station licensed to San Francisco, California. The station has studios along Junipero Serra Boulevard in Daly City, and transmits from Sutro Tower in San Francisco, with a power output of 24,000 watts effective radiated power. The signal can be received throughout the Bay Area with relative ease. There is also a booster station in Martinez, California called KOIT-3 that improves the coverage in the Diablo Valley area. KOIT is owned by Salt Lake City-based Bonneville International. From 2007 through 2017, the station was owned by Entercom.

Radio Station
Radio broadcasting is transmission of audio (sound), sometimes with related metadata, by radio waves to radio receivers belonging to a public audience. In terrestrial radio broadcasting the radio waves are broadcast by a land-based radio station, while in satellite radio the radio waves are broadcast by a satellite in Earth orbit. To receive the content the listener must have a broadcast radio receiver (''radio''). Stations are often affiliated with a radio network which provides content in a common radio format, either in broadcast syndication or simulcast or both. Radio stations broadcast with several different types of modulation: AM radio stations transmit in AM ( amplitude modulation), FM radio stations transmit in FM (frequency modulation), which are older analog audio standards, while newer digital radio stations transmit in several digital audio standards: DAB (digital audio broadcasting), HD radio, DRM ( Digital Radio Mondiale). Television broadcasting ...

Chronicle Publishing Company
The Chronicle Publishing Company was a print and broadcast media corporation headquartered in San Francisco, California that was in operation from 1865 until 2000. Owned for the whole of its existence by the de Young family, CPC was most notable for owning the namesake ''San Francisco Chronicle'' newspaper and KRON-TV, the longtime National Broadcasting Company (NBC) affiliate in the San Francisco Bay Area (San Francisco–Oakland–San Jose) television media market. History The ''Chronicle'' What would become Chronicle Publishing Company was formed on January 16, 1865 when teenage brothers Charles and Michael Henry "M. H." de Young published the first edition of the ''Daily Dramatic Chronicle'', a venture funded by a borrowed $20 gold piece. The paper began with a circulation of two thousand readers daily, which tripled within six months as the paper gained readership in the wake of its breaking the news of the assassination of Abraham Lincoln to San Francisco.

The paper is owned by the Hearst Corporation, which bought it from the de Young family in 2000. It is the only major daily paper covering the city and county of San Francisco. The paper benefited from the growth of San Francisco and had the largest newspaper circulation on the West Coast of the United States by 1880. Like other newspapers, it experienced a rapid fall in circulation in the early 21st century and was ranked 18th nationally by circulation in the first quarter of 2021.

HD Radio
HD Radio (HDR) is a trademark for an in-band on-channel (IBOC) digital radio broadcast technology. It generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by AM and FM radio stations in the United States, Canada, and Mexico, with a few implementations outside North America. The term "on channel" is a misnomer because the system actually broadcasts on the ordinarily unused channels adjacent to an existing radio station's allocation. This leaves the original analog signal intact, allowing enabled receivers to switch between digital and analog as required. In most FM implementations, from 96 to 128 kbps of capacity is available. High-fidelity audio requires only 48 kbps so there is ample capacity for additional channels, which HD Radio refers to as "multicasting". HD Radio is licensed so that the simulcast of the main channel is royalty-free. The company makes its money ...

CBS Radio
CBS Radio was a radio broadcasting company and radio network operator owned by CBS Corporation and founded in 1928, with consolidated radio station groups owned by CBS and Westinghouse Broadcasting/Group W since the 1920s, and Infinity Broadcasting since the 1970s. The broadcasting company was sold to Entercom (now known as Audacy, Inc.) on November 17, 2017. Although CBS's involvement in radio dates back to the establishment of the original CBS Radio Network in 1927, the most recent radio division was formed by the 1997 acquisition of Infinity Broadcasting by CBS owner Westinghouse. In 1999, Infinity became a division of the original Viacom; in 2005, Viacom spun CBS and Infinity Broadcasting back into a separate company, and the division was renamed CBS Radio. It was the last radio group left to be tied to a major broadcast television network, as NBC divested its radio interests in the 1980s, and ABC sold off its division to Citadel Broadcasting (now part of Cumulus Media) i ...

Effective Radiated Power
Effective radiated power (ERP), synonymous with equivalent radiated power, is an IEEE standardized definition of directional radio frequency (RF) power, such as that emitted by a radio transmitter. It is the total power in watts that would have to be radiated by a half-wave dipole antenna to give the same radiation intensity (signal strength or power flux density in watts per square meter) as the actual source antenna at a distant receiver located in the direction of the antenna's strongest beam (main lobe). ERP measures the combination of the power emitted by the transmitter and the ability of the antenna to direct that power in a given direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It is used in electronics and telecommunications, particularly in broadcasting to quantify the apparent power of a broadcasting station experienced by listeners in its reception area. An alternate parameter that measures the same thing is effec ...

Sutro Tower
Sutro Tower is a unique three-legged tall TV and radio lattice tower located in San Francisco, California. Rising from a hill between Twin Peaks and Mount Sutro near Clarendon Heights, it is a prominent feature of the city skyline and a landmark for city residents and visitors. The tower was the tallest structure in San Francisco from the time of its completion in 1973 until it was surpassed by the Salesforce Tower in 2017. The tower is named after the family of Adolph Sutro, a businessman and former mayor of San Francisco. His grandson, Adolph Gilbert Sutro, built a mansion, ''La Avanzada'', on their property in the highest peaks of San Francisco. In 1948, the mansion and property was sold to the American Broadcasting Company, where it became the original home of their San Francisco operation as KGO Television. KGO then formed a consortium with KTVU, KRON, and KPIX, the three other major San Francisco television broadcasters at the time, to build and maintain the tower. It st ...
