KPKR (JACK-FM) 95.7 is owned and operated by RIVER RAT RADIO, LLC and was founded by Sanford and Terry Cohen on December 23, 2007.
As part of ARIZONA’S HOMETOWN RADIO GROUP, the station is part of an nine station group owned and managed by the Cohens, who have been broadcasting in Arizona since 1985.
With JACK-FM, you are listening to the largest playlist in all of radio. KPKR General Manager Lindley Diskin was instrumental in the selection of JACK-FM programming. Who better to know what River Rats like than someone with over 25 YEARS living and doing marketing on the Colorado River. Lindley and her husband, Tim, (“Tijuana Tim”) lead a dynamic marketing and events team making us the go-to partner for many happenings on the River and for retail businesses as well.
We offer both Arizona and California News alternating throughout the day as an acknowledgement of our cross-state border listenership and the tremendous influx of Californians who enjoy partying along the Colorado River.
