Well, it could go up rather fast. To protect their Digital Service Contour the station will need to go up fast. Since most of the new DTV Towers, antennas, etc... have been installed there isn't as much of a rush on construction like there was. A new tower can go up in a day or two.
There really wasn't a problem with Ch.30 if WNPA would have stayed where it is. But by moving the transmitter to Pittsburgh ch.30 couldn't be used because the separation between 29-WWCP Johnstown and a Ch.30 in Pittsburgh would have been too great. The rules are something like adjacent channels are permitted if their seperation is 0-23 miles or greater that 56 miles. Any adjacent channels between 24-55 miles wouldn't be permitted.
Ever since Ch.19 moved into the Pittsburgh TV Market, moving the station closer to Pittsburgh has always been the goal, and the DTV transition is making this possible. Ch.49 wasn't the only possible move, but it probably was the easiest to attempt (Chs.39 & 47 are possibly available). The could have moved to channels higher than 51, but the FCC won't permit a channel move from a "Core Channel" to a "Non-Core Channel"
