Fybush.com has had extensive coverage of what local TV stations had to do to get a signal back on the air. Most had abandoned ESB years earlier for the WTC, so there were no back ups for the OTA signal (remember that the signal going to Optimum, TWC, Comcast and the sattelite companies is separate and were never interrupted. Over the first couple of days there were many stop gap measures each station took including using the Armstrong tower in Alpine NJ, some UHF stations (which I believe were at ESB) and others. It took time to get power and coverage back after the initial temporary arrangements. I believe WCBS may have been first to get back on the air (again, over the air only) using a UHF station. If you have access to Fybush.com, it is worth a read. I also believe that local reporters and network reporters were doing double duty with each others' coverage despite locally limited the national coverage being a local story. Network programming resumed in the rest of the country long before it did in this DMA.
