KATH (AM)

KATH (910 kHz) is an AM radio station licensed to Frisco, Texas, and serving the northern sections of the Dallas-Fort Worth Metroplex. It features a Catholic talk and teaching radio format. Guadalupe Radio Network, a Midland, Texas, based Catholic broadcasting company, took over operation of KATH on October 1, 2006 along with sister station KJON 850 AM. Guadalupe Radio broadcasts Catholic programs in English on KATH and in Spanish on KJON.
KATH broadcasts at 1,000 watts by day. But to avoid interference with other stations on 910 AM, at night it reduces power to 500 watts. The transmitter is off East University Drive (U.S. Route 380) in Little Elm, Texas.

The call letters stood for "Red River Valley." During the 1950s, it played country music during the day and Top 40 at nights. The station shifted to full-time Top 40 by the 1960s and continued until October 1974, when KRRV shifted back to country.
