KJIM-AM Arrives

On July 31, 1991 the station adopted the call letters KJIM and began airing an oldies format. Calls taken from the longtime KJIM on 870 kHz in Fort Worth.

On September 22, 1995, Bob Allen dba Bob Mark Allen Productions, Inc. became licensee after the transfer of ownership was approved by the FCC.

“Bobbin'” Bobby Allen began his radio career in Oklahoma City in the 1950s. He later worked on air at a number of stations in the Midwest including, KIOA and KSO Des Moines, Iowa; KRMG and KELI in Tulsa, Oklahoma. Allen later became a well-known Top 40 DJ and talk show host in Fort Worth, Texas, working at KXOL and KFJZ.

He left radio to establish his own advertising agency to service a growing Tandy Corporation (headquartered in Fort Worth). Allen built his agency on work done for Tandy’s Radio Shack brand.

Later, he became a staple in the automotive business, representing McDavid Automotive Group. Featured in the auto dealer’s TV commercials, Allen’s own Great Dane, Widetrack, became a star of the campaign.

Adding FM to the Service

On March 16, 2016 the Federal Communications Commission granted the construction of an FM translator station, K233CV to Bob Mark Allen Productions, Inc. to simulcast the programming of KJIM 1500 as part of the AM Revitalization Act. The FM signal (now K267CB) at 101.3 began broadcasting full-time, day and night, 7 days a week, on March 27, 2017. The low-power transmitter antenna sits on a tower located in Sherman near Texoma Parkway and Hwy 691. 

Both KJIM features news on the hour from CBS Radio and extended local newscasts each morning. The stations also broadcast an hourly half-cycle on NOAA Weather Radio’s WXK22 which serves the Sherman-Denison area.
