KTTH (770 AM) is a conservative talk radio station, owned by Bonneville International, broadcasting at 770 kHz in Seattle, Washington. The station's transmitter is on Vashon Island, while its studios are located in Seattle's Eastlake district.


The station runs syndicated programming, as well as the popular local morning program "The David Boze Morning Show" and "The Todd Herman Show".   Many of the prominent programs moved from rival local broadcaster, KVI (at one point their slogan was temporarily changed to "3 letter radio is dead"), including Rush Limbaugh and movie critic Michael Medved (whose home station is KTTH).  Their lineup also includes John Gibson, Dave Ramsey, and Mark Levin.

KTTH was the last flagship radio station of the Seattle SuperSonics (now Oklahoma City Thunder) of the National Basketball Association, from 2006 to 2008.

KTTH also airs Seattle Mariners games during NFL football season, when the Mariners' regular flagship station, KIRO, airs a Seahawks game. KTTH is the sister station to KIRO and KIRO-FM.

Starting in the 2011-2012 college sports season, KTTH began airing Washington State Cougars football and men's basketball but moved to sister station KIRO in the 2012-2013 season, while KTTH began airing Seattle University Redhawks men's basketball. KTTH does air Washington State Cougars football and men's basketball games that cannot be aired on KIRO due to conflicts with Seahawks and Mariners games. KTTH also airs select MLB postseason and NBA Finals game broadcasts from ESPN Radio that cannot be aired on KIRO due to various conflicts.


Formerly, the station had the callsign KXA and had a classical music format. It was in a big battle with KING-FM 98.1 and KUOW-FM 94.9, which both on FM were doing a similar format. On October 1, 1980, the station changed to an oldies format and was known as "Old Gold 77 KXA" following a sale. Following a subsequent bankruptcy filing, the station temporarily dumped oldies for sponsored religious programming in 1983.[1] The station's license was transferred to new owners that same year, and a format called "love songs" commenced on October 8, 1984, which was essentially a return to oldies.[2][3] Following a sale to Olympic Broadcasting in 1985, the station flipped to a simulcast of country station KRPM-FM (now KBKS-FM) and changed call letters to KRPM.[4] The station would change call letters to KULL in 1991, and returned to oldies.[5] Country music returned in January 1995, as did the simulcast with KRPM. In a format swap in that same year with AM 1090, the station received the call letters KNWX and the all-news format, followed by the switch to business/talk programming in 1998. The station would acquire the current call letters in 2003 along with the flip to conservative talk. KNWX would move to 1210 AM that same year until 2004, in which it was renamed KWMG (now KMIA).[6]
