The short answer is no available full-power UHF channels. All four major network affiliates in this market had transition DTV channels in the 50's (53, 56, 57, & 59) and one of the requirements of the DTV switch was to give back all the spectrum above channel 51. That leaves only two choices: go back to your analog channel or find a third channel. Three of the four elected to return to their analog channel and the conventional wisdom at the time was high VHF would be okay. WYFF, due to the conventional wisdom being low VHF would be a big problem, began a search for a third channel. Of all the channels from 7-51, there was only one post-transition channel that was available for full power operation, channel 36, so we took it. The other factor involved is that transmitter operating costs are much lower on VHF. So with the cost and the thinking high V would be okay, a number of stations elected to stay on high V. We all know how that turned out. Most got significant power increases after the transition which helped but doesn't solve all the issues.
So there were good reasons at the time. Now the FCC wants to move all OTA television to channels 2-31. Let me know how you think that will work out.
