KFRG airs a country music radio format calling itself "K-FROG" and is believed to be the original "Frog" station under previous owner Keymarket.

Owned by Audacy, Inc., its studios are in Riverside and the transmitter site off Cloudland Truck Trail north of San Bernardino.

It had a Christian radio format and was owned by Channel Six Thirty Two, Inc.[4] At first, its signal was limited, powered at 15,000 watts, less than a third of its current output.

But on February 23, 2007, KKGO-FM 105.1 flipped from classical music to country, putting that format back on a full-powered Los Angeles FM station.

[1] On October 15, 2015, KFRG was named "Station of the Year" by the Inland Empire chapter of the American Advertising Federation.

KVFG has since been sold to El Dorado Broadcasters and in October 2019 it flipped to a Regional Mexican format, branded as "La X 103.1."
