KIRO-FM (97.3 FM) is a radio station in Seattle, Washington, United States (licensed to serve nearby Tacoma), with a news/talk radio format. The outlet is associated with the CBS Radio Network. The station's transmitter is on Tiger Mountain near Issaquah, while its studios are located in Seattle's Eastlake district.
The station was founded as KTNT-FM and was owned by the Tacoma News Tribune. It began broadcasting October 26, 1948. The station exclusively targeted Tacoma and South Puget Sound. In 1976, the call letters were changed to KNBQ, which were later used on 102.9 FM. At that time, the station carried a Top 40 format branded simply as "97.3 KNBQ". When the Tacoma News Tribune sold KNBQ to Viacom in 1987, the station enforced a 'silence over music' policy. The station would move its transmitter to Tiger Mountain during this time to better target the Seattle market as a whole. On February 1, 1988, the station flipped to its long running oldies format as "K-Best 97.3" and picked up the KBSG call letters.Entercom bought the station in 1996. For many years, KBSG was simulcast on 1210 AM; this lasted until 2002. On August 1, 2007, after Entercom traded KBSG, KIRO and KTTH to Bonneville (as part of a multi-market station swap), the station was rebranded from "KBSG 97.3" to "The New B97.3", and dropped the word 'oldies' from the station title.
Exactly one year later, on August 1, 2008, the station's call letters were changed to KIRO-FM.
On August 12, 2008 at 4:23 a.m., KBSG's frequency began to simulcast sister news/talk radio station KIRO; the final song as a classic hits station, Start Me Up by the Rolling Stones, faded out as the FM station joined KIRO AM's Wall Street Journal This Morning in progress. Jane Shannon was first to mention the simulcast of KIRO-AM on 97.3 during the 4:30am local newscast.
On April 1, 2009, KIRO-FM became the primary station and the simulcasting on KIRO (AM) came to an end, marking the completion of the station's transition to the FM frequency that began in August 2008. KIRO (AM) is now a sports talk station, branded as "710 ESPN Seattle."
Also moved from KIRO to KIRO Radio 97.3 FM was the NFL broadcasting duties for the Seattle Seahawks Radio Network (now named the Bing Radio Network). KIRO-FM will continue to simulcast the game and portions of the pre and post-game shows as a member of the network. The Seahawks have been broadcasting on 710 AM in Seattle since the NFL franchise was launched in 1976.
