In the mid-1980s, WTTF-FM was granted a construction permit to operate at an effective radiated power of 50,000 watts making 103.7's signal listenable over much of Northwest Ohio as far west as Defiance, to the east where almost makes to Cleveland, to the south also almost making it to Columbus. WTTF, Inc. built a new tower on County Road 48 to accommodate the larger antenna needed for the upgrade, on the property of its then vice president, Richard J. Wright. After the upgrade, there were few changes in the station's program offerings.
