KDKB (Alt AZ 93.3 FM) is a commercial alternative rock music formatted radio station broadcasting to the Phoenix metropolitan area and based in Mesa, Arizona.[2] It is owned by Hubbard Broadcasting, Inc. and licensed to Phoenix FCC License Sub, LLC. Its previous format was the first Album Oriented Rock (AOR) station in the city of Phoenix, and one of the first AOR stations in America.[citation needed] Its studios are located in Mesa and its transmitter is in South Mountain Park.


Originally, 93.3 MHz was KMND, broadcasting an easy listening music format branded as "Command Radio".

On August 23, 1971, the format was changed to Album Oriented Rock. In many respects, its format was a continuation of the freeform format of KCAC, a daytime-only station that was going bankrupt.[3] According to KDKB co-owner Dwight Tindle, he and KCAC program director, William Edward "Bill" Compton, "invented KDKB" and its air sound.[4] Moreover, Compton and several of KCAC's DJs were hired to staff KDKB.

KDKB was simulcast on the AM dial at 1510 kHz. In 1978, the AM simulcast was broken and 1510 kHz changed formats to oldies. The call letters were changed to KDJQ. In 1986, the format on KDJQ changed to new wave music for a brief time, with John "Johnny D." Dixon as the program director and Jonathan L as assistant program director, music director, and evening personality. 1510 kHz is now broadcasting a Financial/Business News format with the call letters KFNN.

Throughout The '80s, KDKB evolved into more of an adult-leaning direction focusing on the classic rock artists. On September 5, 2006, KDKB began playing full length albums of classic rock artists without the use of any on-air personalities. On September 15, 2006, KDKB returned to its Mainstream Rock format with the new slogan, "93.3 KDKB Everything That Rocks!" including a larger variety of Rock artists along with special programming features including 80’s themed weekends.

In mid 2010, the station initiated the slogan, "93.3 KDKB Rocks Arizona!", and retooled the entire on-air lineup. In the fall of 2013, the station changed their lineup and it features Shmonty & Conklin in the mornings, Ruby Cheeks midday, KDKB's Program Director Paul "Neanderpaul" Marshall in afternoons, Mike Gaube at night.

On September 17, 2014 at 10 AM, KDKB dropped its Rock format after 43 years and moved it to its HD2. It began stunting as "93.3 The Cheese" playing only Jazz-Lounge covers of Alternative songs by Richard Cheese. The entire KDKB airstaff was laid off. At Noon, 93.3 flipped to Alternative Rock as "Alt AZ 93.3". The last song on 93.3 KDKB was Living After Midnight by Judas Priest (promoting a November 2014 concert at Gila River Arena by the group), while the first song on Alt AZ 93.3 was Come With Me Now by KONGOS. This move is to let Hubbard to keep their "Wall of Rock" while eliminating all overlaps between KDKB and sisters Classic Rock KSLX-FM and Active Rock KUPD. [5] [6]

HD radio[edit]

KDKB's HD Radio signal is multiplexed. The main signal is a simulcast of KDKB's alternative rock programming. The second channel carried KDUS "The Fan", a valley AM sports talk radio station until June 21, 2012 when KDUS was replaced by KAZG "Arizona Gold", an oldies station that broadcasts on 1440 AM. On September 17, 2014, when KDKB's main signal flipped to alternative rock, their previous rock format moved to their HD2 subchannel. KDKB's HD2 subchamnnel later switched to a simulcast of oldies-formatted KAZG 1440 AM.
