Sports talk and play-by-play radio is about to make a significant invasion of the FM airwaves in the Twin Cities area.

KFAN (1130 AM) will swap signals next Monday with fellow Clear Channel property KTLK (100.3 FM), which has a conservative politics format.

KFAN late-afternoon host Dan Barreiro praised the imminent move during his show Monday, noting the richer quality of the signal's sound and its ability to deflect listener criticism that the station can be difficult to hear at night in some areas. KFAN is the home of the Minnesota Vikings game broadcasts. The station also will start carrying Minnesota Wild and Minnesota Gophers football games this coming season.

Along with taking over the 1130 AM signal, KTLK also will be heard at 102.5 FM.
