Our Story

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.

Best of all, from I-40 to I-10, you can enjoy JACK-FM on one single channel (95.7) from Needles and Fort Mohave to Quartzsite and Blythe and everywhere in between.

Our 25,000 watt signal originates from above Parker Dam on Black Metal Peak by arrangement with the Metropolitan Water District of Southern California.

Always community minded, our philosophy is to be involved in the communities we serve.  We are members of several area Chambers of Commerce, support a number of local charities and trade associations and sponsor many local events. Thank you for supporting our advertisers and sponsors.

It is, after all, show business, but WITHOUT THE BUSINESS, THERE AIN’T NO SHOW!!  So says JACK!
