KDIA (1640

History
KDIA is a separate entity from the station at
In 1979, a World Administrative Radio Conference (WARC-79) adopted "Radio Regulation No. 480", which stated that "In Region 2, the use of the band 1605-1705 kHz by stations of the broadcasting service shall be subject to a plan to be established by a regional administrative radio conference..." As a consequence, on June 8, 1988, an ITU-sponsored conference held at Rio de Janeiro, Brazil adopted provisions, effective July 1, 1990, to extend the upper end of the Region 2 AM broadcast band, by adding ten frequencies which spanned from 1610 kHz to 1700 kHz.[3]
While the Federal Communications Commission (FCC) was still making U.S. preparations to populate the additional frequencies, known as the "Expanded Band", a provision was added to the Communications Act of 1934 in late 1991 which mandated that priority for assignments would be given to existing daytime-only stations that were located in a community with a population over 100,000, and which also did not have any full-time stations.[4] Taking advantage of this provision, on March 19, 1996, KXBT (now KDYA), 1190 AM in Vallejo, began to also broadcast on 1640 kHz,[5] as the second U.S. station, following WJDM in Elizabeth, New Jersey, authorized to operate on an expanded band frequency.
On March 22, 1996, the FCC issued an updated list of expanded band allotments, which now assigned KXBT to 1630 kHz, so transmissions were switched to that frequency.
The FCC's initial policy was that both the original station and its expanded band counterpart could operate simultaneously for up to five years, after which owners would have to turn in one of the two licenses, depending on whether they preferred the new assignment or elected to remain on the original frequency.[7] However, this deadline has been extended multiple times, and both stations have remained authorized. One restriction is that the FCC has generally required paired original and expanded band stations to remain under common ownership.[9][10]
The station was put on the air by
KDIA has been a Christian talk station since 2002. It has since gone through two upgrades and now covers the San Francisco Bay Area, day and night. In 2009, it became the flagship station for Spanish language night time broadcasts of Oakland Athletics baseball until the middle of the 2010 season, while sibling station KDYA broadcast daytime games.[11]
Effective June 1, 2021, Baybridge Communications sold KDIA and sister station KDYA to Salem Media Group for $600,000.
History of the original KDIA
Use of the KDIA call sign had a prior history in the San Francisco Bay area, and was most recently used on 1310 AM by a station that began broadcasting as KLS in 1922. In 1945, it changed its call letters to KWBR
For four months in 1984-85 the station was owned by Adam Clayton Powell III, during which time it carried the call letters KFYI and broadcast an all-news format.[16]
In the early 1990s KDIA was co-owned by then mayor of
