Bonneville International Corp., parent company of Salt Lake-based KSL radio and KSL-TV, has taken a southern Utah radio station to task for including "KSL" in its call letters.

In a letter to Morgan Skinner, general manager and partner in the St. George radio station KSLI, Bruce T. Reese, vice president and general counsel for Bonneville, said the use of KSLI "would infringe on Bonneville's registered trademark KSL."In the letter, Reese called use of the letters "an attempt to create public confusion and give the impression that KSLI is affiliated with KSL radio."

J.L. Communications took ownership of Color Country Broadcasting, the company that owns KSLI, on Nov. 10. The station was formerly known as KDLX.

Skinner said he chose the call letters to incorporate his initials and those of his partner, Jack London, in the name of the station.

He said the letters stand for Skinner and London Inc., a communications consulting partnership he has been in since 1982.

He said the letter K is the standard beginning for stations west of the Mississippi River.

"There was certainly no attempt on our part to infringe, we're in entirely different markets," Skinner said.

The FCC issued the call letters to the station Nov 16. In the letter, Reese gave Skinner until Nov. 29 to stop using the letters.

Reese declined to comment on the case further, saying only that he had been in contact with KSLI's attorneys.
