KQFW proposes to broadcast from Garland, while their sister station KWDA broadcasts from downtown Dallas. Perhaps they've decided they need a translator in that area for viewers lacking outdoor antennas.
That's still the best theory I have. KQFW has, for the second time, applied to displace to RF 24. They are actually licensed on RF 56 but AFAIK they're not broadcasting. Why else would they want to broadcast from Garland when KWDA has one subchannel with color bars, one with a static page soliciting programming, and one with nothing more than an animated logo?
Their previous RF 24 application was rejected by the FCC, citing excessive interference with K25FW. But I didn't see any changes in this application. The interference report they filed looked exactly the same. It appears to meet FCC regulations, showing interference with only 0.4% of K25FW's potential viewers. But the FCC did their own analysis and came to a different conclusion last time.
BTW, a bit of trivia: D/FW now has 7 consecutive virtual channel numbers: 25 (K25FW), 26 (KODF), 27 (KDFI), 28 (KHPK), 29 (KMPX), 30 (KWDA), and 31 (K31GL). If this goes through, it will add 23 (KUVN) and presumably 24 (KQFW) for a total of 9 in a row. And then if KNAV goes online, that'd add 20 (KBOP), 21 (KTXA), and 22 (KNAV) for a total of 12 in a row!
I wonder what the national record is?
