Yet another station has switched to the "oldies" music format.

The former KFMY ("K-96" at FM-96.1) has switched its call letters to KZOL and instead of playing a "contemporary hits" format, it is now playing "the best music from the '50s to the '70s."KZOL, with a broadcast range from Logan to Richfield, joins the growing ranks of oldies stations that include KRSP-AM and others.

The revised station's target audience is adults ages 29-46, and KZOL is also simulcasting on 960-AM.

Bruce Chandler is doing the morning show for KZOL, while Bill Michaels is the midday host. Brad Pierce does the afternoon show, and Robert Chenault is the evening host. Dave Sebastian handles overnight duties.

The station is not playing the Carpenters, Barry Manilow or Kenny Rogers. It is playing Creedence Clearwater, Aretha Franklin, the Beach Boys and the Supremes and other similar tunes that will likely not be heard on adult contemporary-type stations.

KZOL has a strong signal, transmitting from Lake Mountain, but it is jammed in a rather crowded portion of the radio dial that includes KALL on its left and KSOS to the right.

The AM simulcast signal can only be received from Ogden to Manti at best.

* * KISN radio (FM-97.1) has started its "Middays mean Mazatlan!" promotion.

The station has mailed out contest flyers containing lucky entry numbers to many Utah businesses and will be awarding a total of 80 free trips (including air fare and hotel accommodations) to Mazatlan, Mexico.

To participate, offices must listen to the Jeff Bordner show every weekday (10 a.m.-3 p.m.), when a winning number will be announced hourly. Winners must call within 30 minutes to register for the random vacation drawing held each Friday between 2 and 3 p.m. Drawing winners will receive 10 trips, enough for 10 office workers, to go to Mazatlan.

The contest started Monday and runs through Nov. 18.
