KIRO is a Class A clear channel station. It broadcasts at the maximum power for commercial AM radio stations, 50,000 watts. By day, it uses a non-directional antenna. But to protect the other Class A station on AM 710, WOR New York City, KIRO must use a directional antenna at night. The transmitter is off Dockton Road SW on Vashon Island.[1] KIRO is Washington State's primary entry point station in the Emergency Alert System.


650 KPCB (1927 to 1937)Edit

The station began broadcasting on April 27, 1927, as KPCB on 650 kilocycles. Its founder was Moritz Thomsen of the Pacific Coast Biscuit Company (hence the call sign KPCB) and it was powered at 100 watts. Among its announcers was Chet Huntley, later of television's Huntley-Brinkley Report. In 1935, Saul Haas's Queen City Broadcasting Company took over the station. Queen City increased the power to 500 watts.[2]

Haas, who was well connected in liberal politics and the business community, wanted a simple, pronounceable, and recognizable call sign for his new station. He chose KIRO, which is usually pronounced like the capital of Egypt, "Cairo." The call sign "KING," representing King County, Washington, the county in which Seattle is found, was not available at that time. The KING call letters were later used by a station on AM 1090, and continue on FM classical music station KING-FM.

710 KIRO (1937 to 1960)Edit

In 1937, KIRO was assigned the AM 710 frequency and was granted an increase in power to 1,000 watts. Soon after, KIRO acquired the Seattle CBS Radio Network affiliation rights from KOL AM 1300. Known as "The Friendly Station," KIRO personalities broke from the formal announcing style that was commonplace during the early days of radio. KIRO carried CBS's dramas, comedies, news, sports, soap operas, game shows and big band broadcasts during the "Golden Age of Radio."

On June 29, 1941, a new, 50,000-watt transmitter on Maury Island became operational. From the 1930s through the 1950s, KIRO recorded countless hours of CBS programming for time-delayed rebroadcast to its Pacific Time Zone listeners. These electrical transcriptions are, in many cases, the only recordings made of World War II-era news coverage over the CBS Network. The discs were donated to the University of Washington in the early 1960s and are now held at the National Archives as the Milo Ryan Phonoarchive Collection.

In 1948, the original KIRO-FM went on the air at 100.7 MHz. It initially simulcast its AM sister's programming but in the 1960s it became a beautiful music outlet. In 1975, it changed its call letters to KSEA and today is KKWF. Preparing for a future television allocation, KIRO moved in 1952 from downtown studios to a larger building on Queen Anne Hill. This peak was already home to the KING-TV transmitter and would soon be the site for KOMO-TV as well. Queen City Broadcasting was awarded Seattle's last remaining VHF TV license in 1958, and signed on as CBS affiliate KIRO-TV on February 8th.

1960 to 1980Edit

Haas sold KIRO to Bonneville International Corporation, part of The Church of Jesus Christ of Latter-day Saints, in 1963. He earned a handsome return on his investment 28 years earlier, and would subsequently join Bonneville's board. Bonneville executives Lloyd Cooney and Ken Hatch arrived in Seattle to lead KIRO-AM-FM-TV, in 1964. Like many network radio affiliates following the demise of full-time block programming, KIRO spent the 1960s playing Middle of the road music in addition to long-form news and interview shows.

Morning host Jim French spent several years broadcasting from the rotating restaurant atop the Space Needle and was live on the air from that perch during a 6.7-magnitude earthquake in April, 1965. Bonneville moved its Seattle radio and TV stations to the newly constructed "Broadcast House" at Third and Broad Streets in 1968.

In 1973, KIRO ended a 35-year affiliation with CBS and switched to the Mutual Broadcasting System.[3] Around this time, KIRO also picked up Herb Jepko's "Nitecap," a groundbreaking overnight telephone-talk show from Salt Lake City sister station KSL.

"Newsradio 71 KIRO" debuted in June 1974, with news and talk segments replacing most music programming. In September 1974, KIRO became an NBC Radio Network affiliate, but switched back to CBS in November 1976.[4][5]

1980 to 2008Edit

In 1980, Lloyd Cooney left KIRO to run for the United States Senate. Ken Hatch became President, CEO and Chairman, a position he held until 1995. Under Hatch's leadership, KIRO Inc. acquired AM 1090 KING AM 98.1 KING-FM and Third Avenue Productions. KIRO, Inc. became one of the nation's premier regional broadcast groups, and was led by General Manager Joe Abel during this period.

KIRO was a full service adult contemporary radio station by the mid 1970s, playing music during the day, talk in the evenings, and more music intensive on weekends with exception of sports events. By 1980, the station played music during the day with talk heard night and overnights. The station added talk middays during the week in 1985. By then amounts of music during drive times were down to about 4 songs an hour and during the day, with weekends playing 12 songs an hour. In 1986, KIRO was reclassified as a News and Talk station, adding more news programming and dropping music altogether.

For 25 years, KIRO's morning news, anchored by Bill Yeend, consistently placed at or near the top of the Seattle Arbitron ratings. Gregg Hersholt was the station's morning news anchor for the next 10 years until he left the station on May 28, 2010, ending his 26-year career there. Dave Ross now hosts Seattle's Morning News.

Sports broadcastsEdit

Sports play-by-play has been a staple of the KIRO schedule throughout its history. Since the team's inception in 1976, KIRO has been the flagship radio station for the NFL Seattle Seahawks. About that same time, it was also the flagship station for the Seattle Sounders of the North American Soccer League.[citation needed] From 1985 to 2002, and again since 2009, the station airs Seattle Mariners games. From 1978 to 1987, KIRO was the flagship station of the Seattle SuperSonics. Additionally, KIRO has carried Washington Huskies and Washington State Cougars college football for stints during the '80s and '90s.

KIRO was also the radio home to popular sportscaster Wayne Cody, who did live sideline reports during Seattle Seahawks football games, Washington Huskies college football play-by-play, NASL Seattle Sounders pro soccer play-by-play, and hosted a sports radio talk show weeknights that was the only one of its kind at the time in Seattle.

Dave RossEdit

Dave Ross joined KIRO as a reporter from Atlanta station WSB in 1978 and took over as noon to 3 p.m. talk host in 1987. He moved to the 9 a.m. to noon time slot after the retirement of Jim French in 1992. Ross unsuccessfully ran for Washington's eighth Congressional district as a Democratic candidate in 2004. While Ross unofficially announced his candidacy in May, he did not leave his on-air position until just prior to the July filing deadline. In response to complaints from state Republican party officials, Ross claimed that he was contractually bound to continue working for KIRO until he formally filed to become a candidate.

Ross returned to the air immediately following the November election. He was moved to the afternoon drive-time shift in February, 2005. Ross moved back to his 9am-noon shift in May 2006. Since January 2012, Ross has hosted Seattle's Morning News from 5-9 a.m. In addition to his KIRO work, Ross does a daily commentary on the CBS Radio Network and is also substituted for Charles Osgood on CBS Radio's "Osgood File" segments.

After selling KIRO-TV to the A.H. Belo Corp. in 1995, Bonneville's Seattle radio stations moved to facilities on Eastlake Avenue. KIRO (AM), KIRO-FM (now KKWF) and KNWX (now KTTH) were sold to Entercom Communications of Bala Cynwyd, Pennsylvania, in 1997. Bonneville reacquired KIRO, KTTH, and KBSG (now KIRO-FM) from Entercom in 2007.[6]

Talk on FM, sports on AMEdit

On August 12, 2008, KIRO began simulcasting its programming on sister station KBSG-FM, which dropped its long-running classic hits format. This began the transition of KIRO Newsradio from AM to FM.[7] To complete the transition, KIRO AM switched to a sports radio format, as "710 ESPN Seattle," on April 1, 2009. It regained the rights to broadcast Seattle Mariners games, beginning in the 2009 season.[8] KIRO also simulcasts the Seattle Seahawks games with KIRO-FM, and has extensive team-related programming throughout the year. KIRO-FM continues the news/talk format.[9] In addition, 710 ESPN Seattle is the play-by-play home for the Washington State Cougars college football and basketball broadcasts, and with KIRO-FM, airs Seattle Seahawks NFL games.

Mike Salk was named Program Director of 710 ESPN Seattle on March 13, 2014, returning to the station after a stint in Boston. Before leaving for Boston, Salk had been a co-host on the station.[10]
