KAZG signed on in 1956 as KPOK in Scottsdale. Like many stations in the Phoenix area at the time, it originally ran a country-music format. KPOK became KWBY in 1961. Beginning in 1964, AM 1440 was known as KDOT; it aired an adult-standards format until 1976, when it changed calls to KSGR to fit an oldies format. This lasted until 1978 when it became KOPA. Beginning in the 1960s, it simulcasted on FM 100.7, which continued under various formats and call letters until the mid-1990s. The station was assigned the call letters KOPA on April 24, 1978. On September 1, 1980, the station changed its call sign to KXAM, and adopted an urban format. On March 25, 1982 they reverted to KOPA, then on February 19, 1996 to KSLX, and on April 1, 2001 to the current KAZG. For about a year in the mid-1990s, the format was CNN Headline News.
Programming
KAZG currently programs an automated format of oldies from the 1950s and 1960s, taken via RCS system feed. Features include "14 in a row" song sweeps without commercials, and usage of the branding slogan "Arizona Gold". In 2009, two Phoenix-based talk shows from the defunct radio station KXAM made the move to KAZG: the food-themed "Culinary Confessions with Kim and Don", and sports-talk show "The Positive Side, Sports and Entertainment" that airs from 7-10AM Monday-Friday. "Culinary Confessions" was simulcast on KXAM and KAZG from April 10, 2009 through KXAM's final day of broadcasting on April 15, 2009.
Transmitter
KAZG is popularly referred to as "The Lumberyard" or "Lumberyard 1440" due to the location of its transmitter, directly behind an actual lumber yard at the corner of 64th Street and Thomas Road in south Scottsdale. From this intersection, the transmitter building is accessible via a dirt path bordering the eastern side of the Salt River Project's Crosscut Canal. The station transmits at 5,000 watts daytime, and is thus listenable throughout much of the Phoenix metro area. It has a single-tower, non-directional antenna. Since AM 1440 was originally licensed as an AM daytimer before the Federal Communications Commission abolished the designation, it had been required to turn off its transmitter at local sundown, and allowed to turn it back on at local sunrise. Although KAZG was now licensed by the FCC to transmit at 52 watts of power at night, former owner Sandusky Radio usually opted to turn off the transmitter, apparently to avoid the electricity expense of transmitting at such an unusable power level. On rare occasions, such as when it carried Arizona State baseball or University of Arizona football as an "overflow" station of KDUS, the station would switch to its nighttime power. Radio observers liked to refer to the station's regulator of sunrise/sunset power switches as the "lamp timer," since the times of switching were irregular and tended to drift away from FCC specifications over time, as if the switches were driven by a cheap mechanical lamp timer. In March 2012, KAZG began transmitting at its fully licensed 52 watts of power during nighttime hours, becoming a 24/7 station for the first time in its history. When the Sandusky Radio stations were purchased by Hubbard in 2013, this practice continued. On January 25, 2016 KAZG rebranded as "Oldies 92.7". K224CJ had been independently owned and had simulcast several stations in its history. It was not until 2017 that Hubbard bought the translator for $1.8 million, setting a record for the highest sale price ever commanded by an FM translator.
