Three Utah radio stations, KLZX, KSL and KSFI, were recently ranked by Arbitron's radio ratings as being among the stations with the biggest audiences in the nation for their particular markets.

KLZX (FM-93.3) is in fact ranked as the No. 1 "classic rock 'n' roll" radio station in the nation, according to its 8.4 percent Wasatch Front audience share. In other words, no other U.S. classic rock station has a bigger percentage of its market audience than does KLZX.KSL (AM-1160) is ranked second in the news/information category with a 9.6 percent audience share. The top station in the nation is KMOX (St. Louis) with a phenomenal 16.6 percent audience share.

KSFI (alias FM-100.3) was the other Utah station ranked by Arbitron with an eighth-place finish (8.3 percent audience share) in the adult contemporary category.

The low percentage for KLZX's winning share might, at least in part, be due to the fact that classic rock is a specialized musical format. Both new/information and adult contemporary formats are much broader in their scope of audience and thus attract more sheer numbers of listeners.

Arbitron based this information on listeners age 12 and up during the fall of 1990 from the Mondays to Sunday, 6 a.m. until midnight, period.

- KALL (AM-910) has signed Tom Barberi to a new five-year contract. He started at KALL in July 1971, and this new deal ensures that Barberi will celebrate his silver anniversary at the station in 1996.

"Tom Barberi is still the premier radio personality in this market," Jan Bagley, station manager, said. "His ratings continue to hold, and in a business that's notorious for job changes, to be in one place with one station 20 years speaks for itself."

Bagley said Barberi's current contract is nearing its expiration and many other competing stations were after his services.

Barberi, a native of northern California, is famous in local radio for his "check" on the Legislature and also for his "It's Your Nickel" segment.
