Somewhere along the same lines, how did WVFX Clarksburg get by with keeping their 10.x PSIP data? They began as analog OTA channel 46, then were assigned to digital RF channel 10, and took up both branding themselves as "Fox 10" and using channel 10 as their PSIP channel. Finally they ended up on RF 13, but still have 10 as their PSIP channel to this day.
Another example of "just sort of not following the rules"? Seems as though they'd be forced to revert to PSIP 46.
I doubt there is anything hing illegal here. Some folks can work the rules.
Somehow there was a way to change your PSIP when the first digital conversation happened if there wasn't a local station on that channel. You would lose the folks looking for your old "channel" but everyone had to rescan their TV and 10 would show up before 46. IIRC virtual channels are on the FCC website so they had to know about it. Somebody figured it out. If they were not following the commission rules the competition would have filed something with the FCC. There are lawyers and engineers that deal with the commission daily. They are expensive but you have to deal with them if you are in the OTA business.
