WQLN DT 50 (54-1, 54-2 and 54-3) and WQLN 91.3 FM will be off the air for most of the day Thursday. The stations will be off due to work being done on a back up generator for the stations. With no power, WQLN will not be available on cable, satellite or the internet for the FM side. In addition, the offices will be closed since there will be no power in the building. The work on the back up generator is expected to be completed by August. At that point, any power problems will be handled by the enginerering staff at WJET / WFXP TV with pending layoffs expected at WQLN in the next few months.
