Two stations merge

On December 26, 1967, KTAR Broadcasting Company and Eller Outdoor Advertising Company announced their intention to merge to form Combined Communications Corporation. The merger, however, created a complication in Yuma, where Eller owned KBLU-AM-TV and KTAR owned KYUM. The FCC approved the merger in 1969 on the condition that one of the AM stations be divested. Due to a stronger signal and favorable dial position, the parent company chose to keep the 560 AM license, which became KBLU, and to donate the 1320 AM license to

In a quick succession of owners, Commonwealth was acquired by Capstar in 1997. Capstar merged with Chancellor Broadcasting to form AMFM in 1998.

Expanded Band assignment

On March 17, 1997 the FCC announced that eighty-eight stations had been given permission to move to newly available " Expanded Band" transmitting frequencies, ranging from 1610 to 1700 kHz, with KBLU authorized to move from 560 to 1640 kHz."FCC Public Notice: Mass Media Bureau Announces Revised AM Expanded Band Allotment Plan and Filing Window for Eligible Stations"
(FCC DA 97-537), March 17, 1997.
However, the station never procured the Construction Permit needed to implement the authorization, so the expanded band station was never built.


Later history

Clear Channel sold its Yuma stations—KBLU, KTTI and KQSR—to current owner El Dorado Broadcasters in 2007. In 2017, KBLU became one of the few local stations that broadcast its content on line. In 2018, the webcast was restricted to only the Russ Clark Show, which through its
