Kksf
KKSF (910 AM) is a licensed broadcasting commercial radio station coming out of Oakland, California. The station is owned by iHeartMedia and serves the San Francisco-Oakland- San Jose media market. It operates as the Bay Area affiliate for the Black Information Network. The transmitter and twin tower array are located on Point Isabel in Richmond, on the San Francisco Bay. KDIA utilizes one of KKSF's two towers during the day. KKSF operates at 20,000 watts during the day and 5,000 watts at night, using a directional antenna at all times. Because radio waves travel farther at night, KKSF must reduce its power after sunset to protect other stations on AM 910. KKSF's studios are located in San Francisco's SoMa district. History KLX KKSF was started by the ''Oakland Tribune'' newspaper. Beginning in early 1922, the Tribune had supplied content for Preston D. Allen's station, KZM, located atop the Oakland Hotel. Following a suggestion by Allen, the newspaper decided to establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KOSF
KOSF (103.7 FM) is a commercial classic hits radio station that is licensed to San Francisco, California. Owned by iHeartMedia, the station serves the San Francisco Bay Area. The KOSF studios are located in San Francisco's SoMa district, while the station transmitter is based atop San Bruno Mountain near Daly City. KOSF broadcasts in HD Radio with two digital subchannels. History Early years The former ABC Radio-owned station started on November 3, 1947 as KGO-FM. In earlier days, it simulcast its sister station, KGO (810 AM), occasionally airing a stereo version of ''The Lawrence Welk Show''. By the late 1960s, as the Federal Communications Commission (FCC) began requiring FM stations to offer separate programming from that of their AM counterparts, KGO-FM, like other ABC-owned FM stations, was an outlet for ''Love'', an automated progressive rock format. KGO-FM changed its call sign to KSFX in early 1971, keeping its progressive rock format until May 1973. At that time, KS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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).

Radio Studio
A recording studio is a specialized facility for sound recording, mixing, and audio production of instrumental or vocal musical performances, spoken words, and other sounds. They range in size from a small in-home project studio large enough to record a single singer-guitarist, to a large building with space for a full orchestra of 100 or more musicians. Ideally, both the recording and monitoring (listening and mixing) spaces are specially designed by an acoustician or audio engineer to achieve optimum acoustic properties (acoustic isolation or diffusion or absorption of reflected sound echoes that could otherwise interfere with the sound heard by the listener). Recording studios may be used to record singers, instrumental musicians (e.g., electric guitar, piano, saxophone, or ensembles such as orchestras), voice-over artists for advertisements or dialogue replacement in film, television, or animation, foley, or to record their accompanying musical soundtracks.

Directional Antenna
A directional antenna or beam antenna is an antenna which radiates or receives greater power in specific directions allowing increased performance and reduced interference from unwanted sources. Directional antennas provide increased performance over dipole antennas—or omnidirectional antennas in general—when greater concentration of radiation in a certain direction is desired. A high-gain antenna (HGA) is a directional antenna with a focused, narrow radiowave beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas are also in use all over Earth, most successfully in flat, open areas where there are no mountains to disrupt radiowaves. By contrast, a low-gain antenna (LGA) is an omnidirectional antenna with a broad radiowave beam width, that allows the signal to propagate reasonably well even in mountainous regions and is thus more reliable regardless of terrain. Low-gain antennas are often used in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KDIA
KDIA (1640 kHz) is a commercial AM radio station licensed to Vallejo, California, and serving the San Francisco Bay Area. It is owned by the Salem Media Group and broadcasts a Christian talk and teaching radio format. Salem also owns KFAX 1100 AM which airs a separate schedule of Christian programming. The radio studios and offices are on Liberty Street in Fremont. KDIA transmits 10,000 watts. By day, it is non-directional, using one of the KKSF 910 AM towers in Richmond on San Francisco Bay. At night, it is directional, using a four-tower array on Noble Road in Vallejo. History KDIA is a separate entity from the station at 1310 AM that held the KDIA call letters for many years. The 1640 AM frequency was licensed as part of an extension of the AM band, and adopted the abandoned KDIA call letters. It signed on the air in . In 1979, a World Administrative Radio Conference (WARC-79) adopted "Radio Regulation No. 480", which stated that "In Region 2, the use of the ban ...

San Francisco Bay
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay meas ...

Tower Array
A tower array is an arrangement of multiple radio towers which are mast radiators in a phased array. They were originally developed as ground-based tracking radars. Tower arrays can consist of free-standing or guyed towers or a mix of them. Tower arrays are used to constitute a directional antenna of a mediumwave or longwave radio station. The number of towers in a tower array can vary. In many arrays all towers have the same height, but there are also arrays of towers of different height. The arrangement can vary. For directional antennas with fixed radiation pattern, linear arrangements are preferred, while for switchable directional patterns (usually for daytime groundwave versus nighttime skywave), square arrangements are chosen. Examples Tower arrays with guyed masts * Longwave transmitter Europe 1 * Transmitter Weisskirchen * Beidweiler Longwave Transmitter * Transmitter Wachenbrunn * Transmitter Ismaning (VoA-Station) Tower arrays with free standing towers * Junglinster L ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter is an electronic device which produces radio waves with an antenna (radio), antenna. The transmitter itself generates a radio frequency alternating current, which is applied to the Antenna (radio), antenna. When excited by this alternating current, the antenna radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio and television broadcasting stations, cell phones, walkie-talkies, Wireless LAN, wireless computer networks, Bluetooth enabled devices, garage door openers, two-way radios in aircraft, ships, spacecraft, radar sets and navigational beacons. The term ''transmitter'' is usually limited to equipment that generates radio waves for Communication engineering, communication purposes; or radiolocation, such as radar and navigational transmitters.
