KISN jumped the gun earlier this week and started simulcasting on its sister station KLUB's frequency (AM-570), several weeks ahead of the planned date listed in this column last week.

The old KLUB is no more. Only the KLUB sports emphasis remains. KISN and KLUB will be identical, except when Dave Blackwell does his sports shows or when the AM station broadcasts Salt Lake Trappers or Utah Jazz games.The only real confusion for listeners so far is that KISN still identifies itself only as "KISN FM-97." Ideally, it might be best to use a "KISN FM and AM" identification.

When KISN simulcasts, it does seem to stand out on the AM dial, since no other local station has an adult "hits" format on AM.

KISN originally intended to begin simulcasts on June 1, but since the equipment for the change was in place early, the switch was flipped two weeks ahead of schedule.

(BU) NEW STATION - As reported Wednesday, KSL's "Mark in the Morning" - Mark Van Wagoner - has left the station. He was last heard on AM-1160 Monday.

He's now with KMGR Radio, alias "Magic-107," recently purchased by a Seattle-based company, Bingham Communications Group. The new station plans to simulcast a special local morning show, from 6-10 a.m. starting June 13, on AM-1230 and FM-107.5.

The show will feature adult contemporary music, and Van Wagoner will apparently have the freedom to design his own show and even pick out the music.

Van Wagoner told KSL General Manager Russ Wood that he got a salary offer that he couldn't refuse. Dan Jessop is filling in the KSL morning spot, at least temporarily.

Mark is the third big-name deejay to leave KSL in the past several years. Danny Kramer left KSL in 1985 for a big-bucks deal at KALL, and his afternoon show successor, Tom Bock, left KSL in December and signed on at KALL's sister station, KLCY, earlier this year.
