KNX (AM)

KNX-AM-FM broadcast "traffic and weather together" every ten minutes on the fives with traffic reports on the freeways and toll roads in the Greater Los Angeles area and weather forecasts for Southern California, 24 hours a day, seven days a week. Local news coverage include the latest news from the Los Angeles City Council, Los Angeles County Board of Supervisors and public safety. Business news from Bloomberg Radio and sports headlines are heard every half hour. Each hour begins with world and national news from CBS News Radio. The two stations are branded as "KNX News 97.1 FM".{{Cite web|title=Audacy Brings KNX Los Angeles To FM|url=https://radioinsight.com/headlines/216593/audacy-brings-knx-to-fm/|access-date=December 7, 2021|website=RadioInsight|date=December 6, 2021 |language=en-US}}

Although KNX received its first broadcasting station license on December 8, 1921,{{cite web |title=KNX Los Angeles Turns 99 |url=https://www.radioheritage.net/Story449.asp |website=radioheritage.net |access-date=March 9, 2022}} the station has traditionally dated its founding to September 10, 1920,[https://books.google.com/books?id=HCkEAAAAMBAJ&pg=PA56 "45th Year Marked By Station KNX"], Billboard, September 25, 1965, page 56. reflecting boadcasts conducted by Fred Christian over his amateur station, 6ADZ.The government's June 30, 1921, annual listing of amateur radio stations has 6ADZ licensed to the Electric Lighting Supply Company, 216 West Third Street, Los Angeles.

The leading "6" in 6ADZ's call sign specified that the station was located in the sixth Radio Inspection district. The fact that the call sign's first letter, "A", was in the range A-W reflected its status as a standard amateur station.

Mr. Christian was trained as a shipboard radio operator. He lived at 5118½ Harold Way in Hollywood, California. He was manager for the Electric Lighting Supply Company at 216 West Third Street, Los Angeles.{{cite news |title=Advertisements Column 1 |url=https://cdnc.ucr.edu/cgi-bin/cdnc?a=d&d=LAH19131001.2.67.1&e=-------en--20--1--txt-txIN--------1 |access-date=March 9, 2022 |work=Los Angeles Herald |publisher=California Digital Newspaper Collection |date=October 1, 1913 |page=5}}{{cite web |title=Los Angeles radio (1920) |url=https://earlyradiohistory.us/1920LA.htm |website=earlyradiohistory.us |access-date=March 9, 2022}} He once explained that he began the broadcasts in order to provide something to listen to for those customers who had constructed receivers from parts purchased for their radio shack.[https://www.worldradiohistory.com/Archive-Other-Documments/LA-Radio-Guide/LA-Radio-Guide-1995-11-12.pdf#page=22 "KNX Spans 7 Decades of Los Angeles Radio History"], Los Angeles Radio Guide, November/December 1995, pages 22-26. Christian began making broadcasts with a five-watt vacuum-tube transmitter, operating on the standard amateur wavelength of 200 meters (1500 kHz).{{cite news |title=Here's how KNX 1070 AM is celebrating 100 years on the radio |url=https://www.dailynews.com/2020/09/01/heres-how-knx-1070-am-is-celebrating-100-years-on-the-radio/ |access-date=March 9, 2022 |work=Daily News |date=September 1, 2020}}

Initially there were no specific standards in the United States for radio stations making transmissions intended for the general public, and numerous stations under various classifications made entertainment broadcasts. However, effective December 1, 1921, the Department of Commerce, regulators of radio at this time, adopted a regulation that formally created a broadcasting station category, and stations were now required to hold a Limited Commercial license authorizing operation on wavelengths of 360 meters (833 kHz) for "entertainment" broadcasts or 485 meters (619 kHz) for "market and weather reports".[https://babel.hathitrust.org/cgi/pt?id=umn.319510008420257&view=1up&seq=292 "Miscellaneous: Amendments to Regulations"], Radio Service Bulletin, January 3, 1922, page 10. By the end of 1922 over 500 stations were authorized nationwide.

On December 8, 1921, the Electric Lighting Supply Company was issued a broadcasting station license with the randomly assigned call letters KGC, the second in the county after KQL,{{cite web |last1=Mishkind |first1=Barry |title=The First Hundred Stations |url=https://www.oldradio.com/archives/general/first100.html |website=Broadcast Archive |access-date=March 9, 2022}} authorizing operation on the 360-meter entertainment wavelength. The station's location was listed as Fred Christian's Harold Way home.[https://babel.hathitrust.org/cgi/pt?id=osu.32435066705633&view=1up&seq=192 "New Stations"], Radio Service Bulletin, January 3, 1922, page 2. One year Limited Commercial license with the call letters KGC, serial #248, issued December 8, 1921, to the Electric Lighting Supply Company, 5118{{frac|1|2}} Harold Way, Hollywood, California. This license was canceled on June 20, 1922. The shared 360 meter wavelength required timesharing agreements between an increasing number of stations needing exclusive time periods. On May 4 the Los Angeles Times reported that a total of seven local stations were slated to make broadcasts that day, comprising a schedule that ran from noon to 9 p.m., with KGC assigned 2-2:30 and 7:30-8 p.m."What's Doing Today: Radio", Los Angeles Times, May 4, 1922, Part II, page 20.{{cite web |last1=Mishkind |first1=Barry |title=General History |url=https://www.oldradio.com/archives/general/index.html |website=Broadcast Archive |access-date=March 9, 2022 |date=November 25, 2015}}

On May 4, 1922, the Electric Lighting Supply Company was issued a broadcasting license for a station with the randomly assigned call letters of KNX, also on 360 meters, and located at the company's Los Angeles store on West Third Street.[https://babel.hathitrust.org/cgi/pt?id=hvd.hxhh8g&view=1up&seq=1107 "New Stations"], Radio Service Bulletin, June 1, 1922, page 3. Three month Limited Commercial license with the call letters KNX, serial #358, issued May 4, 1922, to the Electric Lighting Supply Company, 216 West Third Street, Los Angeles. This was technically considered to be a second station in addition to KGC, however, after KGC was formally deleted on June 20, 1922, the Department of Commerce concluded that KGC and KNX were functionally the same station, and Federal Communications Commission (FCC) records list KGC's December 8, 1921, initial license date as KNX's "date first licensed".Due to the overlap of the KGC and KNX licenses, the Department of Commerce's June 1, 1922, list of active authorizations included both KGC and KNX ([https://babel.hathitrust.org/cgi/pt?id=umn.319510008420257&view=1up&seq=407 June 1, 1922 list]). However, the station list in the May 11, 1922, issue of the Los Angeles Times no longer included KGC, with KNX designated as one of the "stations not yet on the air". ("What's Doing Today: Radio", Los Angeles Times, May 11, 1922, Part II, pages 1, 10.)

The new authorization coincided with preparations for a move to the California Theater, broadcasting live music, with Fred Christian continuing as station manager.{{cite web |title=KNX Los Angeles - A Centennial Station |url=http://www.theradiohistorian.org/knx/knx.html |website=theradiohistorian.org |access-date=March 9, 2022}} On June 12, 1922, the Los Angeles Times reported that "After more than two months of preparation, the new broadcast station at the California Theater had its opening program Saturday evening at 9:15, sending out a wavelength of 510 meters [588 kHz].Although 360 meters was the normal transmitting wavelength during this period, on occasion the sixth district Radio Inspector, J. F. Dillon, would give permission for stations to make broadcasts on 510 meters. ("Radio Puts on Miners' Benefit", Oakland Tribune, September 15, 1922, page 32.) The station is said to be one of the best in the land, the call letters of which are KNX.""Listening in: KHJ", Los Angeles Times, June 12, 1922, Part II, page 2. KNX's regular broadcast schedule on 360 meters was 9:00 to 10:00 a.m."What's Doing Today: Radio", Los Angeles Times, June 8, 1922, Part II, page 24. A week after it commenced operations from the theater, the Times reported that "Numerous reports have come into The Times radio department commending the quality and audibility of material broadcast from KNX, the California Theater radiophone. This station differs from other stations in that it gives its listeners-in the music of the complete orchestra of the California Theater."(untitled filler, third column), Los Angeles Times, June 19, 1922, Part II, page 2.

KNX's power was raised to 100 watts in early August 1922."KHJ's 'Radio Cave'", Los Angeles Times, August 6, 1922, Part II, page 6.

In the fall of 1924, Guy Earl Jr., owner of the Los Angeles Evening Express, arranged for the newspaper's purchase of KNX. The Express made significant upgrades, including increasing the power to 500 watts, and began broadcasting from the Paul G. Hoffman Studebaker building in Hollywood."New Radio Station to Open Tonight", Santa Ana (California) Register, October 10, 1924, page 1. KNX was one of the last stations to remain on the original 360 meter wavelength, and the newspaper engineered a move to 890 kHz. It remained on this frequency until November 11, 1928,[https://babel.hathitrust.org/cgi/pt?id=uc1.b3221814&view=1up&seq=245 Commercial and Government Radio Stations of the U.S.] (Edition June 30, 1928), page 173. when the station was reassigned to 1050 kHz, under the provisions of a major reallocation resulting from the Federal Radio Commission's (FRC) General Order 40.

In early 1928, Guy Earle sold his share of the Evening Express newspaper and reorganized KNX as the Western Broadcast Company. In 1929, Earle moved the KNX studios to the Paramount Pictures lot, signing a five-year contract, and the station's transmitter power was upgraded from 500 to 5,000 watts. In 1930, KNX became the first station to broadcast the Academy Awards. In 1932, it increased to 10,000 watts. In 1933, the station moved its studios to the former Peerless Motor Company building at 5939 Sunset Boulevard in Hollywood,{{cite web |last1=Harnisch |first1=Larry |title=Mary Mallory / Hollywood Heights: Hollywood's Long Struggle for a Movie Museum |url=https://ladailymirror.com/2021/09/28/mary-mallory-hollywood-heights-hollywoods-long-struggle-for-a-movie-museum/ |website=ladailymirror.com |access-date=March 9, 2022 |language=en |date=September 28, 2021 |quote=The Motion Picture Museum and Hall of Fame, about 1932.

CBS purchased KNX in 1936, and began operating it as its West Coast flagship, which ended CBS's eight-year affiliation with KHJ."Biggest station deal in history effected."

That October, the station carried Orson Welles' celebrated version of The War of the Worlds. In March 1941, the station was shifted to 1070 AM as part of the North American Regional Broadcasting Agreement assignments, where it has been ever since.

Theatre legend Jerome Lawrence got his start in radio writing at KNX in the late 1930s. Legendary performers from the "Golden Age of Radio" used KNX studios for their national broadcasts, included Jack Benny, Bing Crosby, George Burns, Edgar Bergen and Gene Autry. Steve Allen conducted a freewheeling late night show over KNX in the late 1940s, which opened the door to his national success. TV situation comedy star Bob Crane was KNX's morning host between 1957 and 1965 at the same time he was appearing as a featured supporting player on the ABC television network series The Donna Reed Show.[http://www.who2.com/bobcrane.html "Bob Crane Biography"] (who2.com)

On March 30, 1948, KNX added a sister station. The original station with the call sign KNX-FM signed on the air, mostly simulcasting 1070 AM.{{cite news|title=KNX-FM Starts|url=http://www.americanradiohistory.com/Archive-BC/BC-1948/1948-04-05-BC.pdf|access-date=November 22, 2014|agency=Broadcasting|date=April 5, 1948}} At first it was on the old FM band, but switched to 93.1 a few years later. Today that station is KCBS-FM, while a new version of KNX-FM exists today on 97.1 as a simlicast of the AM station.

In 1951, KNX gained a television cousin when CBS acquired KTSL channel 2 and rebranded it as KNXT."Don Lee sale; General Tire bid sets record."

It traces its history back to 1930s experimental broadcasts and was originally owned by broadcast pioneer Don Lee.

KNX was a strong competitor in the Los Angeles market while Bob Crane was its morning personality, but began declining in popularity after he left to star in the CBS television series Hogan's Heroes. Following the example of corporate sister station WCBS in New York City, which had enjoyed success with an all-news format, KNX then became an all-news station in the spring of 1968.[http://www.knx1070.com/pages/2098423.php knx1070 Our Heritage] {{webarchive |url=https://web.archive.org/web/20090314035927/http://www.knx1070.com/pages/2098423.php |date=March 14, 2009 }} By chance, its first major breaking news coverage was a major worldwide story that happened locally: the assassination of Democratic Presidential candidate Robert F. Kennedy, in the Ambassador Hotel in Los Angeles, on June 5 of that year.{{citation needed|date=April 2015}}

In August 2005, KNX moved out of Columbia Square after operating there for 67 years, and began broadcasting from new studios in the Miracle Mile district on Wilshire Boulevard.[https://www.knx1070.com/pages/3872.php KNX History]

In 2009, KNX adopted the slogan "All news, all the time". It was previously used for 40 years by KFWB, KNX's historic rival in the news radio wars before both became sister stations through the 1995 merger of Westinghouse Electric (KFWB's owner) and CBS. KFWB's format change to news/talk in September 2009, left KNX as the only all-news outlet in the Los Angeles area, which is now emphasized in its alternate slogan, "Southern California's only 24-hour local news & traffic station".

In 2017, KNX won its first ever national Edward R. Murrow award for "Breaking News". The station was also nominated for two 2017 NAB Marconi awards, Legendary Station of the Year and News/Talk Station of the Year.

On February 2, 2017, CBS agreed to merge CBS Radio with Entercom, then the fourth-largest radio broadcaster in the United States. The sale was conducted tax-free using a Reverse Morris Trust. While CBS shareholders retained a 72% ownership stake in the combined company, Entercom was the surviving entity, separating KNX from KCBS-TV and KCAL-TV.{{cite web|title=CBS Sets Radio Division Merger With Entercom|url=https://variety.com/2017/biz/news/cbs-entercom-radio-division-merger-1201976392/|website=Variety|date=February 2, 2017|access-date=February 2, 2017}}{{Cite web|url=https://fortune.com/2017/02/02/cbs-entercom-radio-merger/|title=CBS and Entercom Are Merging Their Radio Stations|website=Fortune|access-date=February 2, 2017}} The merger was approved on November 9, and was consummated 8 days later.{{Cite web |url=http://www.entercom.com/entercom-receives-fcc-approval-for-merger-with-cbs-radio#.Wg54UWVqaNZ |title=Entercom Receives FCC Approval for Merger with CBS Radio |access-date=November 17, 2017 |archive-url=https://web.archive.org/web/20171117122333/http://www.entercom.com/entercom-receives-fcc-approval-for-merger-with-cbs-radio#.Wg54UWVqaNZ |archive-date=November 17, 2017 |url-status=dead }}[https://radioinsight.com/headlines/121072/entercom-completes-cbs-radio-merger/ Entercom Completes CBS Radio Merger]

On December 6, 2021, KNX announced that it would be adding an FM simulcast. KNX's all-news programming would also be heard on sister station KNOU, replacing the Top 40 format on the station that began in 2009. KNOU changed its call letters to KNX-FM on December 21, 2021, to match its AM simulcast partner.

The station's antenna array features a 494-foot (150m) main antenna. The original main tower (circa 1936) was destroyed by vandals on September 14, 1965. An unused 365-foot (111m) tower was brought in from KFAC (now KWKW) and was used while the new main antenna was constructed. This antenna was formerly in what is now a residential area to the south of the main antenna.

The 365-foot tower now serves as KNX's emergency antenna. It was later relocated when much of the site was dedicated as a park in Torrance. It is now north of the main antenna, within the park.

Only one antenna is active at a time. An experiment in the late 1960s, using both antennas in a directional setup during the daytime was abandoned.

The 494-foot main antenna is 0.53λ, or 193.5 electrical degrees. It has an efficiency of 400.73 mV/m/kW at 1 km.From FCC public information files. This is much better than average for a Class A station's main antenna. The FCC's minimum efficiency requirement is 362.10 mV/m/kW at 1 km.From FCC rules, 47 CFR Part 73.

The 365-foot emergency antenna is 0.40λ, or 145.5 electrical degrees. It has an efficiency of about 343 mV/m/kW at 1 km.Calculated from the electrical height, using FCC formulae. This is much better than average for a Class A emergency antenna but is inadequate for the main antenna.
