ANOTHER VHF DTV PROBLEM

Our neighbors to the north in Oklahoma City will find KWTV/9 (CBS) simulcasting on channel 39 if the STA is approved by the FCC.

Citing similar reception problems, recall that KTVT/11, also CBS, in D/FW will be operating on RF-19 starting Tuesday 4 AUG 2009.

The OKC situation is interesting because that facility is running a healthy 62.2 kw at 1525 feet HAAT. (Compare it to KTVT with 23 kw on RF-11 at 1707 feet). If KWTV's power at that elevation (in mostly flat terrain) is so troublesome, what does it portend for DTV's future on the VHF band?

From my location in Frisco, all three of the Vs in North Texas come in fine, with KTVT is among the most robust (modulo thunderstorms). I have a Terk HDTVa, with each dipole extended to 29-inches, hanging from the ceiling of a single story house. My favorable situation notwithstanding, based upon the filings from KTVT (and now KWTV), there are sufficient reception problems in the digital world with VHF to make UHF appealing, even with its higher transmitter power bill.
