The main full power station broadcasts on RF 12, and shows a virtual channel 12 as well and IDs as KBMT HD 12.1/K-JAC (A virtual call if you will. It is the former call of our former NBC afilliate) 12.2. They also are responsible for programming the two LD stations (RF 36 and RF 43) which both ID as 12.3 MYTX and 12.4 Azteca.
On my Vizio, they show as 12.1, 12.2, 12.3
Considering it's about a different market (Beaumont, TX), I hesitate to get too far off topic in this New Orleans thread, but from the info at RabbitEars
(expand all those stations showing Display Channel = 12 in the 1st column), you've got a nightmare mix of stations at different RF frequencies (some appear to be repeaters for the main channel), but you should
only be seeing a single 12.1
, and 12.5
on your Vizio (not two 12.3s, 12.4s,...) as indicated above. If there's two different RF possibilities when the viewer selects channel 12.3, for example, the content should be the same programming, but perhaps not the best quality reception, depending on which RF broadcast the set selects to tune to. I don't see how having two 12.3s, two 12.4s, ... can work, but if so, how does a viewer know which RF broadcast is the source--whether viewing, pointing an antenna, or troubleshooting?
The previously mentioned DVR's 70.1, 70.2, and beyond, should be the second 12.3, 12.4, etc. if the receiving device (TV or DVR) is detecting different RF channels encoded to show the same virtual channel.
Depending on how Vizio's setup works, I'd guess the first
12.n virtual channel assignment encountered may be the one stored by the set, even if a stronger signal at a different RF channel is encountered later in the spectrum scan, resulting in a reassignment of the default virtual channel to one of the alternate 70.n values.
It sounds tedious, but perhaps there's an option to delete the weaker RF channel from the Vizio config, then manually add the stronger RF channel and as a result, have it display/tune the correct 12.n virtual channel? (You might have to delete all RF channels for a specific 12.n virtual before you can manually add the strongest one back manually.)
I haven't looked, but perhaps there's already an HDTV thread here for the Beaumont folks, or it might be time to start one. Otherwise, I'll try to limit my future comments to ones pertinent to the New Orleans DMA.
