Washington Redskins games will be heard exclusively on FM radio for the first time in the team's history next season with the announcement yesterday of a new three-year deal between the team and Infinity-owned WJFK, the station that has built its reputation in this market by airing Howard Stern and G. Gordon Liddy, among others.

No terms were announced, but industry sources said the team was looking for a deal in the $3.5 million to $4 million a year range, and WJFK in recent weeks was the only contender apparently willing to pay that price.

The Redskins were on WTEM-AM the last three years. The station announced last year it would not enter the bidding to retain the rights.

"It's a good deal for both of us," said Ken Stevens, vice president and general manager of WJFK, adding that he will begin negotiations immediately to retain the longtime Redskins broadcast team of play-by-play man Frank Herzog and analysts Sonny Jurgensen and Sam Huff. Jurgensen told WJFK listeners about the agreement during an interview on the station's afternoon show featuring Don Geronimo and Mike O'Meara. Stevens said the station also will have extensive pregame and postgame shows as part of the agreement. Infinity-owned WLIF-FM in Baltimore also will carry the games.
