Fellow PBRTV correspondent Tom Lavery notes that the 88.7 mHz signal for which Duquesne University has applied is in Cranberry Township, Venango County, not Cranberry Township, Butler County, as I incorrectly assumed and reported.
The application, available on the FCC website, clearly bears that information out.
As the map above illustrates, the full-power, Class B station, with an effective radiated power of 50kW, would throw a signal over Oil City and Clarion, and would reach areas near Grove City and Slippery Rock as well.
I apologize for the error. — Jason Togyer, PBRTV Correspondent
