On the AM dial, WSPZ, AM-690, has canceled Scott Griffin's morning show "The Cage" and will replace it with a still-to-be-announced nationally syndicated program.

And on the FM side, WJOX has moved from its 100.5 frequency to 94.5, a change that station management said should strengthen its coverage in hard-to-reach areas outside Birmingham.

Citadel Broadcasting owns both stations.

Griffin, who worked for about 12 years at WJOX when it was an AM station, joined WSPZ when that station started in January 2007.

His rotating co-hosts on "The Cage" were Birmingham News columnists Kevin Scarbinsky and Ray Melick and Mike Dubberly of Fox 6.

"Scott did a great job for us when he was here," Ryan Haney, program director for both WJOX and WSPZ, said Friday. "It was just that we needed to go in another direction in the morning, we felt, to try to get competitive again."

Griffin said Citadel canceled his show because it did not generate enough advertising.

"There was some advertising, but not enough," he said Friday.

Griffin said he will continue to work as a sports reporter-anchor for TV station CBS 42.

In place of Griffin's show, Citadel plans to close the deal on a national program that should begin airing within the next two weeks, Haney said.

Haney would not say what that show will be, but one possibility is the syndicated Don Imus show "Imus in the Morning," which is a Citadel property.

Until then, WSPZ will carry "The First Team on Fox" with Steven Czaban, Haney said.

Meanwhile, WJOX, which moved to the 100.5 FM frequency in January 2007, will move again to the 94.5 signal. Previously, 94.5 was the home of WYSF-FM, a Top 40 station.

The switch should strengthen WJOX's coverage in areas north and east of Birmingham where some listeners had trouble picking up the station, said Gigi South, the Birmingham market manager for Citadel Broadcasting.

To give listeners time to adjust to the frequency switch, Citadel will simulcast WJOX on both the 94.5 and 100.5 signals for the next two weeks, Haney said.

"We want to do that to make sure that the people who have listened to 100.5 know that we are moving," Haney said.

Citadel plans to launch a new station on the 100.5 FM signal "soon," South said. She would not say what format the station will be.
