KFNN (1510 AM) is a commercial radio station licensed to Mesa, Arizona, and serving the Phoenix metropolitan area.

However, because 1510 AM is a clear-channel frequency reserved for Class A WLAC Nashville, Tennessee, KFNN must reduce nighttime power to only 100 watts to prevent interference.

In 1970, it was relaunched as KMND ("Command Radio"), simulcasting an easy listening music format with co-owned 93.3 KMND-FM.

The call signs switched KDKB and KDKB-FM, playing an Album Oriented Rock format.

Don McDonald's financial planning program was one of the first major national shows broadcast on the station, along with Ken and Daria Dolan, who featured a money and investment related program syndicated from the WOR Radio Network.

He had been a long time morning show host and station manager, with much of his career spent in Cleveland.

Other national business and money shows heard on KFNN included Clark Howard, Gary Kaltbaum and Ray Lucia.

The station's brand was changed to reflect the broader nature of program content that relates to all matters money.

In 2019, KFNN began adding some conservative and libertarian-leaning political talk, including Todd Schnitt, Chris Plante, Michael J. Knowles and Ben Shapiro.
