By chance on my Sony HD receiver, I discovered that WSAJ 91.1 from Grove City College is broadcasting an HD signal. I could only lock on it briefly but the station is definitely running Hybrid Digital. The station has recently increased their power and antenna height which is good for them but bad for WQLN 91.3. The WQLN Oil City translator at 91.9 cannot be reached by the main signal to rebroadcast WQLN. According to WQLN Chief Engineer Aaron Coseo, it’s directly due to channel interference from WSAJ & possibly HD interference as well. Listeners in Oil City are encouraged to listen to WQLN at until the issue is resolved.
