I heard a rumor about KDTN 2 leaving its equipment on as a LP Station after the switch. Now I can not confirm this rumor as of right now.

Rumor about KDTN 2

Don't see how they could do that -- they don't have a license for an analog LP station on that channel in this area, nor will the FCC grant them one simply because they used to occupy that channel as a full power station. Only way that it would be possible is if they had a construction permit to move a displaced out of core LP station to channel 2...and I haven't seen such a thing (or even an application) in the FCC database.
This rumor may have come from a mix-up with low-power station KSFW 2. Currently they are an analog station covering Thackerville, OK, but they've applied to move to Collinsville, TX and switch to digital. The new digital station would have much greater range and would reach much of the north Dallas metroplex in addition to the lake Texoma area.
If the move goes through, this could result an a conflict over virtual channels: KDTN is on physical channel 43, but their virtual channel is still 2.1. If KSFW were also on virtual channel 2.1, most DTV receivers would only be able to tune in one or the other. I assume the FCC could resolve the conflict by requiring KSFW to use a different virtual channel, such as 2.2, but I'm no expert on FCC rules and regulations. Can someone clarify?

Yep, that's exactly what's in the standard - from ATSC A/65C - Program and System Information Protocol:
RF channel 2 was previously used by KDTN, and KDTN's DTV RF channel is 43. So the standard will require KSFW-LD to use major channel 43.
Full-license stations have been very good (though not perfect) about obeying this standard. I'm not that confident LP stations will be as good.

Actually, in my experience, most receivers would still be able to receive both stations. They'd have two 2.1's; dial up 2.1 and you'll get KSFW, press channel-up and you'll get KDTN. (in that order, because KDTN is on a higher RF frequency and would scan in second)
But you're right, in that there are some exceptions. Luckily, in those cases it would be the culprit -- KSFW -- that those receivers would be unable to receive. Again, because KDTN would scan in second due to its higher RF frequency - and it would overwrite KSFW's "slot".

Thanks. That makes sense: it limits a virtual-channel conflict to the two stations in question. If KSFW used an unused major channel number, the problem could recur if that channel were later used as an RF channel. A similar situation will arise if KHFW-LP's digital application is approved; they'll be on RF channel 29 and virtual channel 30, while KMPX will be the reverse.
These situations can still cause problems for many DTV receivers, though. Everything will work OK if both stations are picked up during the scan, but if the stations are in different directions (as will generally be the case here) the viewer may need to rotate their antenna to pick up one or the other, so the scan would only pick up one. It would then be impossible to tune in the other, since entering either the RF channel or virtual channel number would cause the receiver to tune to the channel picked up during the scan.
Some DTV receivers have ways around this conundrum. The Dish Network CECBs, for example, let you enter RF channel numbers directly; I've heard the Zenith/Insignia CECBs are similar, although I don't own one myself. The Channel Master CECBs let you rotate your antenna then do an "update" scan, which doesn't clear the channel table, to add the other station. But there are DTV receivers (including but not limited to CECBs) that will be flummoxed by the situation.
KSFW and KDTN target different demographics (one's English and the other is Spanish) so any conflict is largely academic: almost no one will be interested in receiving both. KHFW and KMPX, though, are both Spanish (although one is religious and the other is general entertainment), so their demographic targets may overlap more.
A business author once told me that the key to Disney's success is that they consider EVERYBODY to be their competition. In some way they're all competing for the customer's time, attention, money, loyalty and goodwill. So when it comes to pleasing their customers at the movies or in their parks, Disney figures it needs to be better at what it does than anybody else is at what they do. That's a very tall order.
I thought we were talking about KDTN not Disney
