88-457: A broadcast transmitter , a transmitter used in broadcasting , as in FM radio transmitter or television transmitter . This usage typically includes both the transmitter proper, the antenna, and often the building it is housed in. A transmitter can be a separate piece of electronic equipment, or an electrical circuit within another electronic device. A transmitter and a receiver combined in one unit

132-472: A frequency modulation (FM) transmitter, it is added by varying the radio signal's frequency slightly. Many other types of modulation are also used. The radio signal from the transmitter is applied to the antenna , which radiates the energy as radio waves. The antenna may be enclosed inside the case or attached to the outside of the transmitter, as in portable devices such as cell phones, walkie-talkies, and garage door openers . In more powerful transmitters,

176-429: A radio frequency signal which when applied to the antenna produces the radio waves, called the carrier signal . It combines the carrier with the modulation signal, a process called modulation . The information can be added to the carrier in several different ways, in different types of transmitters. In an amplitude modulation (AM) transmitter, the information is added to the radio signal by varying its amplitude . In

220-507: A broadcasting station category, which set aside the wavelength of 360 meters (833 kHz) for entertainment broadcasts, and 485 meters (619 kHz) for farm market and weather reports. On April 21, 1922, the Deseret News , a Salt Lake City newspaper owned by the Church of Jesus Christ of Latter-day Saints (LDS), was issued a license for a new station on both broadcasting wavelengths. This

264-518: A high voltage spark between two conductors. Beginning in 1895, Guglielmo Marconi developed the first practical radio communication systems using these transmitters, and radio began to be used commercially around 1900. Spark transmitters could not transmit audio (sound) and instead transmitted information by radiotelegraphy : the operator tapped on a telegraph key which turned the transmitter on-and-off to produce radio wave pulses spelling out text messages in telegraphic code, usually Morse code . At

308-413: A radio wave. A radio transmitter is an electronic circuit which transforms electric power from a power source, a battery or mains power, into a radio frequency alternating current to apply to the antenna, and the antenna radiates the energy from this current as radio waves. The transmitter also encodes information such as an audio or video signal into the radio frequency current to be carried by

352-506: A speech by Salt Lake City Mayor C. Clarence Nelson. In 1924, KZN was sold to John Cope and his father, F.W. Cope, who formed the Radio Service Corporation of Utah. Ownership was changed to Cope & Johnson, and the station's frequency to 1120 kHz. The call letters became KFPT. This new call sign came from an alphabetical roster of available call letters that were normally assigned to new stations. KFPT, still located atop

Generators of radio waves for heating or industrial purposes, such as microwave ovens or diathermy equipment, are not usually called transmitters, even though they often have similar circuits. The term is popularly used more specifically to refer to

704-647: The Deseret News until 1964, when Bonneville International Corporation was formed as the parent company for the LDS Church's broadcasting interests. A notable program from KSL's history was Herb Jepko 's Nitecap call-in show. It aired overnight on KSL from 1964 to 1990. This was one of the first U.S. radio talk shows to be syndicated nationally, airing on numerous Mutual Broadcasting System Network stations. Jepko usually steered clear of politics and controversy, instead sharing friendly chit-chat with his callers. KSL

880-613: The "clear channel" assignments, on 1130 kHz. An upgrade from 5,000 to the current 50,000 watts was dedicated October 22, 1932. In March 1941, with the implementation of the North American Regional Broadcasting Agreement , KSL was shifted to 1160 kHz, although it maintained its status as a "clear channel" station. In 1932, KSL joined the CBS Radio Network . It remained with CBS until 2005, when it switched to ABC News Radio . KSL-FM debuted in 1946 on

924-676: The 1920s. All these early technologies were replaced by vacuum tube transmitters in the 1920s, which used the feedback oscillator invented by Edwin Armstrong and Alexander Meissner around 1912, based on the Audion ( triode ) vacuum tube invented by Lee De Forest in 1906. Vacuum tube transmitters were inexpensive and produced continuous waves , and could be easily modulated to transmit audio (sound) using amplitude modulation (AM). This made AM radio broadcasting possible, which began in about 1920. Practical frequency modulation (FM) transmission

Music & the Spoken Word is a weekly broadcast of The Tabernacle Choir at Temple Square , which is also syndicated nationwide via CBS Radio and television. Continuously airing on KSL since 1929 , it is one of the longest-running radio programs in the world. In addition, it is one of only two radio shows to be inaugurated into

1100-488: The Deseret News Building, made its formal debut on June 13, 1924. In early 1925 ownership was changed to the Radio Service Corporation of Utah, and the station's frequency to 1150 kHz. On March 24, 1925, the call letters were changed from KFPT to KSL, and the frequency to 1000 kHz, with the "S" and "L" standing for "Salt Lake". (The KSL call sign had been assigned to a San Francisco station from March 1922 until it

1144-435: The LDS Church, though the Church later reacquired full interest in the station. In 1927, the station moved to 990 kHz. The recently formed Federal Radio Commission adopted General Order 40 in 1928, which included 40 " clear channel " allocations, which were assignments providing for high-powered stations with extensive nighttime coverage. The resulting reallocation was implemented on November 11, 1928, with KSL given one of

1188-472: The US, these fall under Part 15 of the Federal Communications Commission (FCC) regulations. Although they can be operated without a license, these devices still generally must be type-approved before sale. The first primitive radio transmitters (called spark gap transmitters ) were built by German physicist Heinrich Hertz in 1887 during his pioneering investigations of radio waves. These generated radio waves by

1232-610: The antenna may be located on top of a building or on a separate tower, and connected to the transmitter by a feed line , that is a transmission line . Electromagnetic waves are radiated by electric charges when they are accelerated . Radio waves , electromagnetic waves of radio frequency , are generated by time-varying electric currents , consisting of electrons flowing through a metal conductor called an antenna which are changing their velocity and thus accelerating. An alternating current flowing back and forth in an antenna will create an oscillating magnetic field around

1276-461: The background, to exchange data with wireless networks . The need to conserve bandwidth in the increasingly congested radio spectrum is driving the development of new types of transmitters such as spread spectrum , trunked radio systems and cognitive radio . A related trend has been an ongoing transition from analog to digital radio transmission methods. Digital modulation can have greater spectral efficiency than analog modulation ; that

1320-419: The conductor. The alternating voltage will also charge the ends of the conductor alternately positive and negative, creating an oscillating electric field around the conductor. If the frequency of the oscillations is high enough, in the radio frequency range above about 20 kHz, the oscillating coupled electric and magnetic fields will radiate away from the antenna into space as an electromagnetic wave,

1364-417: The early 2000s. Management saw that some radio listeners preferred the FM band and rarely tuned to AM stations. It decided KSL 1160 needed an FM partner. In September 2005, Bonneville acquired FM station KQMB 102.7. KQMB was converted to a simulcast of KSL. To match its AM counterpart, KQMB changed its call letters to KSL-FM. The joint operation was branded as "KSL Newsradio 102.7 FM & 1160 AM." Initially

1408-421: The output frequency. Older designs used an oscillator at a lower frequency, which was multiplied by frequency multipliers to get a signal at the desired frequency. Modern designs more commonly use an oscillator at the operating frequency which is stabilized by phase locking to a very stable lower frequency reference, usually a crystal oscillator. Two radio transmitters in the same area that attempt to transmit on

1452-400: The radio waves. When they strike the antenna of a radio receiver , the waves excite similar (but less powerful) radio frequency currents in it. The radio receiver extracts the information from the received waves. A practical radio transmitter mainly consists of the following parts: In higher frequency transmitters, in the UHF and microwave range, free running oscillators are unstable at

1496-486: The receiver, these pulses were sometimes directly recorded on paper tapes, but more common was audible reception. The pulses were audible as beeps in the receiver's earphones, which were translated back to text by an operator who knew Morse code. These spark-gap transmitters were used during the first three decades of radio (1887–1917), called the wireless telegraphy or "spark" era. Because they generated damped waves , spark transmitters were electrically "noisy". Their energy

1540-475: The same frequency will interfere with each other, causing garbled reception, so neither transmission may be received clearly. Interference with radio transmissions can not only have a large economic cost, it can be life-threatening (for example, in the case of interference with emergency communications or air traffic control ). For this reason, in most countries, use of transmitters is strictly controlled by law. Transmitters must be licensed by governments, under

1628-415: The then sparsely-populated FM band at 100.1 (later 100.3) MHz. This was a different station from the current-day KSL-FM. After simulcasting KSL for its first two decades, the FM station switched to beautiful music , quarter hour sweeps of largely instrumental music with limited commercials and chatter. This was a contrast to KSL's format of news and talk along with middle of the road music. In 1977, KSL-FM

1672-512: The transmitter usually must hold a government license, such as a general radiotelephone operator license , which is obtained by passing a test demonstrating adequate technical and legal knowledge of safe radio operation. Exceptions to the above regulations allow the unlicensed use of low-power short-range transmitters in consumer products such as cell phones , cordless telephones , wireless microphones , walkie-talkies , Wi-Fi and Bluetooth devices, garage door openers , and baby monitors . In

1716-558: Was deleted in June 1923.) Earl J. Glade (later a four-term mayor of Salt Lake City) joined the station in 1925 and guided KSL's operations for the next fourteen years. John F. Fitzpatrick , publisher of The Salt Lake Tribune (owned by the Kearns Corporation) acquired a quarter interest of KSL for a modest price, as did the LDS Church. This was the Tribune's first business partnership with

1760-440: Was invented by Edwin Armstrong in 1933, who showed that it was less vulnerable to noise and static than AM. The first FM radio station was licensed in 1937. Experimental television transmission had been conducted by radio stations since the late 1920s, but practical television broadcasting didn't begin until the late 1930s. The development of radar during World War II motivated the evolution of high frequency transmitters in

1804-462: Was sold to Simmons Family Inc. This was due to FCC restrictions on multiple station ownership at the time. The new owners changed the call letters to KSFI . KSL 1160 gained a television counterpart in 1949, KSL-TV . (KSL-TV started as a CBS affiliate. It then switched to NBC in 1995. That was after former NBC affiliate KUTV Channel 2 came under the ownership of CBS, following its acquisition by Westinghouse ). KSL-FM-TV remained subsidiaries of

1848-492: Was spread over a broad band of frequencies , creating radio noise which interfered with other transmitters. Damped wave emissions were banned by international law in 1934. Two short-lived competing transmitter technologies came into use after the turn of the century, which were the first continuous wave transmitters: the arc converter ( Poulsen arc ) in 1904 and the Alexanderson alternator around 1910, which were used into

1892-706: Was the first broadcasting station licensed in the state of Utah. The new station's call sign was KZN. At this time call letters were generally randomly assigned from a roster of available call signs, but it is possible that the KZN call sign was derived from the Zion concept and common motif in the Latter Day Saint movement . The station was located on the roof of the Deseret News Building. KZN's first broadcast began at 3:00 p.m. on May 6, 1922, and included an 8:00 p.m. dedication address by LDS Church president Heber J. Grant , followed by

1936-541: Was the radio flagship station for Utah Jazz NBA basketball games from the team's 1979 arrival through the 1985-1986 season. The Jazz are now heard on KZNS 1280 AM and KZNS-FM 97.5 . In the mid-1980s, many radio listeners were tuning to FM stations for music. Gradually KSL adopted an all-news and talk format. It completely dropped music programming, aside from its Sunday broadcasts of the Mormon Tabernacle Choir . Station ownership limitations were loosened in
