KLSD (1360 AM) is a commercial radio station in San Diego, California. It is owned by iHeartMedia and broadcasts a talk format branded "The Patriot AM 1360". KLSD is San Diego's oldest licensed radio station, dating back to 1922, and using the call sign KGB for most of its history. Nationally syndicated shows heard on KLSD include Glenn Beck, Jesse Kelly, Dana Loesch, Mark Levin, Chad Benson, Red Eye Radio and America in the Morning.

Founded by W. K. Azbill in his home in the Normal Heights neighborhood of San Diego, it first signed on the air as KFBC on July 14, 1922, broadcasting on 833.3 kHz (360 meters) with 10 watts of power and sharing the time with eight other San Diego radio stations. Future CBS and NBC broadcaster Art Linkletter began his broadcasting career in 1933 as an announcer for KGB. He was promoted to program director in 1934 and station manager in 1936. Linkletter also developed his "Man on the Street" audience participation shows while with KGB. In 1936, KGB switched its network affiliation from CBS to the Mutual Broadcasting System. Around the same time, future television screenwriter Larry Rhine became a screenwriter and morning host for KGB. During World War II, KGB featured content relating to the U. S. military. The United States Navy broadcast ship signals on the station, and KGB hosted shows originating from the Marine Corps Recruit Depot and Naval Training Center San Diego. Those shows featured the United States Marine Corps with film stars such as Ginger Rogers and Henry Fonda as special guests. On April 1, 1964, Willet Brown bought KGB. Nearly two months into retaining Drake Chenault, KGB had its ratings improve from worst to best in San Diego. In 1972, KGB became an early adopter and pioneer of what is now called the album oriented rock format, simulcasting with co owned KGB FM. KGB AM returned to Top 40 in 1974.

On March 15, 1982, KGB's call sign changed to KCNN, and the format changed to an audio simulcast of CNN. General manager Jim Price based the format change on anticipation of listeners preferring FM for music. Then on October 7, 1983, KCNN became KPQP with an adult standards format. The call sign changed to KPOP on August 1, 1986. Nationwide was later acquired by Jacor in 1997. Then in 1998, Clear Channel Communications bought Jacor and its stations including KPOP. Beginning in the 2000–01 season, KPOP became the radio home of San Diego State Aztecs men's basketball. In June 2001, former KFMB Hudson and Bauer co host Joe Bauer became morning drive host of Breakfast with Bauer at KPOP. In 2002, KPOP added a rotating set of lifestyle programs at 6 p. m. weeknights.

The station became a progressive talk station under the call sign KLSD on August 23, 2004. The call sign reportedly stood for "Liberal San Diego". Most of the programming came from the Air America Radio Network. Local programming included the morning show, hosted by Stacy Taylor and the nationally syndicated Air America host Jon Elliott. However, due to the added cost, Clear Channel decided against the move, and KLSD still broadcasts at 5,000 watts day/1,000 watts night.

After registering a 2.2 rating in the winter 2006–07 period, KLSD's ratings declined to 0.9 and 1.0 for the spring and summer 2007 ratings books, according to Arbitron. In an August 31, 2007, article, San Diego Union Tribune sports reporter Jay Posner found that Clear Channel registered the domain name "xtrasports1360. com", sparking speculation that the company would change KLSD to a sports format. The blog SDRadio. net hinted at a format change nearly a week earlier August 23. Following the SDRadio. net report, listeners organized and held rallies to attempt to persuade Clear Channel to keep the format. A documentary titled Save KLSD: Media Consolidation and Local Radio was made about the effort. Posner reported for the Union Tribune on October 13, 2007, that Clear Channel planned on changing KLSD to sports. On November 12, 2007, KLSD flipped to the new format as XTRA Sports 1360, inheriting the former branding from XETRA AM, which would change its callsign to XEWW a month later. The first local live program, which aired at 3 p. m. that day, was hosted by Lee Hacksaw Hamilton. Outside of local programming, the new XTRA Sports broadcast the national Fox Sports Radio network. In 2008, KLSD broadcast select San Diego State Aztecs baseball. Hacksaw left the station in 2008 when his contract was not renewed. KLSD was not listed in the Arbitron ratings book in the winter 2007–08 period. KLSD returned to the Arbitron ratings books in June 2009 with an 0.6 share. The ratings would remain around that level in the final months of 2009. Beginning in the 2009–10 season, KLSD became the San Diego affiliate for the Los Angeles Lakers. On July 21, 2014, KLSD rebranded as "Xtra 1360 Fox Sports San Diego" as a partnership with the Fox Sports San Diego TV network. In September 2014, Clear Channel Communications became iHeartMedia. On May 8, 2017, KLSD and sister station KGB FM signed a contract with San Diego State University to broadcast San Diego State Aztecs football and men's basketball after the previous contract with XEPRS AM "The Mighty 1090" expired. Beginning in the fall of 2020, KLSD began broadcasting some ESPN Radio programming during the week, with ESPN Radio's East Coast morning drive show Keyshawn, JWill, and Zubin weekdays at 3 a. m. and weekend mornings to noon.

On August 31, 2022, iHeartMedia announced that it would swap the formats of 760 KGB and KLSD at midnight the next day, with KGB's nationally syndicated conservative talk shows moving to the 1360 AM signal and KLSD's sports programming moving to KGB on 760 AM. The swap, timed to coincide with the beginning of the college football season, moved San Diego State football and the other sports programming to a stronger signal.

The station operates with 5,000 watts by day and 1,000 watts at night using a non directional antenna. It shares a broadcasting tower with co owned KGB FM and KHTS FM on 52nd Street in the Oak Park neighborhood of San Diego. Programming is also heard on FM translator K277DH at 103.3 MHz. The radio studios and offices are located at the Serra Mesa section of northeastern San Diego.
