Grant Nielsen and Amanda Dickson of KSL (AM-1160) are back on top as the No. 1 morning show for adults.

According to the latest rating estimates from Arbitron, "Grant and Amanda" have an 8 percent audience share. That's 0.2 better than runner-up Dain Craig and Peggy Ijams of KSFI (alias "Fm-100"), who held the top spot last winter.Percentages for every morning team seemed to go down in the spring.

Last winter, "Dain and Peggy' had a 10.7 percent share, while "Grant and Amanda" were second at 9.0.

The approach of the two morning teams is quite different. KSL updates listeners on the latest news, weather and traffic in a detailed fashion with no music.

KSFI, meanwhile, focuses on lots of easy listening music and only the barest essentials in news, weather and traffic.

For whatever reason last spring, Wasatch Front adult radio listeners, ages 25-54, preferred the news over music.

The other big news is that the KFNZ morning sport talk show with David James, Gordon Monson and Ron Boone has jumped to fourth place on the strength of a high interest in the Utah Jazz.

The 7-10 a.m. weekday show was in the top 10 previously, but Jazz fever and a great sports talk show have helped double their audience.
