Oakland, California
Oakland is a city in the East Bay region of the San Francisco Bay Area in the U.S. state of California. It is the county seat and most populous city in Alameda County, California, Alameda County, with a population of 440,646 in 2020. A major West Coast of the United States, West Coast port, Oakland is the most populous city in the East Bay, the third most populous city in the Bay Area, and the eighth most populous city in California. It serves as the Bay Area's trade center: the Port of Oakland is the busiest port in Northern California, and the fifth- or sixth-busiest in the United States. A charter city, Oakland was municipal corporation, incorporated on May 4, 1852, in the wake of the state's increasing population due to the California gold rush. Oakland's territory covers what was once a mosaic of California coastal prairie, California coastal terrace prairie, oak woodland, and north coastal scrub. In the late 18th century, it became part of a large ''rancho'' grant in the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KYLD
KYLD (94.9 FM) is a commercial radio station in San Francisco, California, serving the San Francisco Bay Area and owned by San Antonio–based iHeartMedia. The station airs a contemporary hit radio format on its analog primary signal. The station has studios located in the SoMa district of San Francisco, and the transmitter is located atop the San Bruno Mountains. Other uses of the KSAN call letters The call letters of KSAN have been used by four unrelated radio stations and one related TV station in the San Francisco Bay Area since the late 1950s. In the early 1960s, KSAN 1450 AM became KSOL and programmed R&B music, and was also notable for DJ Sly Stone (Sylvester Stewart), who went on to fame as a musician, fronting the band Sly and the Family Stone.

Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations on board ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KKSF (AM)
KKSF (910 kHz) is a commercial AM radio station licensed to Oakland, California and serving the San Francisco Bay Area. The station is owned by iHeartMedia and has an all-news radio format, with programming from the co-owned Black Information Network (BIN). The studios are located on Townsend Street in San Francisco's SoMa district. The station's transmitter and two- 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 transmits with 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 from interference. History KLX KKSF was founded by the '' Oakland Tribune'' newspaper. Starting in early 1922, the Tribune supplied content for Preston D. Allen's station, KZM, located on top of the Oakland Hotel.

Oakland Tribune
The ''Oakland Tribune'' was a daily newspaper published in Oakland, California, and a predecessor of the '' East Bay Times''. It was published by the Bay Area News Group (BANG), a subsidiary of MediaNews Group. Founded in 1874, the ''Tribune'' rose to become an influential daily newspaper. With the decline of print media, in 2016, the paper announced that the ''Tribune'', along with its owner's other newspapers in the East Bay, would be folded into a new newspaper titled the ''East Bay Times'' starting April 5, 2016. The former nameplates of the consolidated newspapers will continue to be published every Friday as weekly community supplements. ''Oakland Voices'' is also a successor of the ''Tribune'', developing out of a collaboration with the Maynard Institute for Journalism Education Origin The ''Tribune'' was founded February 21, 1874, by George Staniford and Benet A. Dewes. The ''Oakland Daily Tribune'' was first printed at 468 Ninth St. as a 4-page, 3-column newspaper, 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sign-on
A sign-on (or start-up in Commonwealth countries except Canada) is the beginning of operations for a radio or television station, generally at the start of each day. It is the opposite of a sign-off (or closedown in Commonwealth countries except Canada), which is the sequence of operations involved when a radio or television station shuts down its transmitters and goes off the air for a predetermined period; generally, this occurs during the overnight hours although a broadcaster's digital specialty or sub-channels may sign-on and sign-off at significantly different times than its main channels. Like other television programming, sign-on and sign-off sequences can be initiated by a broadcast automation system, and automatic transmission systems can turn the carrier signal and transmitter on/off by remote control. Sign-on and sign-off sequences have become less common due to the increasing prevalence of 24/7 broadcasting. However, some national broadcasters continue the pra ...

Digital Subchannel
In broadcasting, digital subchannels are a method of transmitting more than one independent program stream simultaneously from the same digital radio or television station on the same radio frequency channel. This is done by using data compression techniques to reduce the size of each individual program stream, and multiplexing to combine them into a single signal. The practice is sometimes called " multicasting". ATSC television United States The ATSC digital television standard used in the United States supports multiple program streams over-the-air, allowing television stations to transmit one or more subchannels over a single digital signal. A virtual channel numbering scheme distinguishes broadcast subchannels by appending the television channel number with a period digit (".xx"). Simultaneously, the suffix indicates that a television station offers additional programming streams. By convention, the suffix position ".1" is normally used to refer to the station's main d ...

HD Radio
HD Radio (HDR) is a trademark for in-band on-channel (IBOC) digital radio broadcast technology. HD radio generally simulcast, simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by FM broadcasting, FM radio stations in the United States, U.S. Virgin Islands, Canada, Mexico and the Philippines, with a few implementations outside North America. HD Radio transmits the digital signals in unused portions of the same band as the analog AM and FM signals. As a result, radios are more easily designed to pick up both signals, which is why the HD in HD Radio is sometimes referred to stand for "hybrid digital", not "high definition". Officially, HD is not intended to stand for any term in HD Radio, it is simply part of iBiquity's trademark, and does not have any meaning on its own. HD Radios tune into the station's analog signal first and then look for a digital signal. The European DRM system shares c ...

Transmitter
In electronics and telecommunications, a radio transmitter or just transmitter (often abbreviated as XMTR or TX in technical documents) is an electronic device which produces radio waves with an antenna (radio), antenna with the purpose of signal transmission to a radio receiver. 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 Electromagnetic radiation, radiates radio waves. Transmitters are necessary component parts of all electronic devices that communicate by radio communication, radio, such as radio broadcasting, radio (audio) 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 fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Directional Antenna
A directional antenna or beam antenna is an antenna that radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only. This can increase the power transmitted to receivers in that direction, or reduce interference from unwanted sources. This contrasts with omnidirectional antennas such as dipole antennas which radiate radio waves over a wide angle, or receive from a wide angle. The extent to which an antenna's angular distribution of radiated power, its radiation pattern, is concentrated in one direction is measured by a parameter called antenna gain. A high-gain antenna (HGA) is a directional antenna with a focused, narrow beam width, permitting more precise targeting of the radio signals. Most commonly referred to during space missions, these antennas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 * Junglins ...
