In 1987, when I was the Chief Engineer for 620, WSUN, someone shot one of the insulators on the north tower. At that time, the owners, CBS Radio, had a Structural Engineer design a crutch to support one leg of the north tower so that the insulator could be removed and returned to Lapp, the company that built the original insulators for the old Blaw Knox tower.
After the crutch was installed on the tower, the FCC required that 620 reduce their nighttime power from the directional 10kw to a non-directional 250 watts.
The station ran in that mode for a month or more ... the time that it took to have the insulator replaced.
I'm guessing that the station is operating under similar licensing conditions today.
I've heard that the new towers will be shorter than the old towers. This will reduce the transmitting efficiency of the station.
Perhaps they're going for a power increase?
