For 80 years, Butler County residents have tuned in to hear WISR on 680 AM. And now, they can hear it on the FM dial too.
WISR is officially on the air at 107.5 FM.
Recently, the FCC allowed AM radio stations to acquire an FM signal and after months of preparations, 107.5 is officially live.
Now, 680 AM isn’t going anywhere. It will remain on the air and have the same strength and power.
