KDFW 4.2 gone?

No big loss given 5.2, 8.2, and 8.3, but FWIW, KDFW is no longer broadcasting weather radar on subchannel 4.2.

If this had been any network other than Fox, dropping a subchannel would've let the station reduce their compression on the main HDTV channel, thus improving the picture quality a bit. But my understanding is Fox is different: they have a fixed-bandwidth network feed with room for one subchannel, so the PQ remains the same whether the affiliate uses the subchannel or not. (It might improve PQ on local HD content, though.)
 
When I re-scanned my digital signals recently, I discovered a 35.4 that has no video or audio. This is in addition to 14-8 and 14-9 that are also blank. Any idea what these signals are?

Ch. 35 is KDFW's digital signal, so apparently 35.4 is what replaced 4.2. Wonder what it's for?

Trip, thanks for the info on 14.8/14.9. I saw those appear a few months ago, then they disappeared again. I guess KERA didn't have them configured right at first (or maybe my DTV receivers got updated to not show them ;) ).

Ah so that's how the "Update" is supposed to work. My Sony HDTV a 2008 model has that, but it has never updated itself OTA. I did one myself through the USB port and since then I know Sony issued two other updates but when I go to the Updates menu the TV says "No Updates Available".

Another piece of technology I am not too sure about is the built-in TV Guide On Screen "TVGOS". It lists stations from other Texas markets mixed in with the DFW stations even though it asks for the Zip Code during setup. I wish they would fix the TVGOS to display only stations the tuner receives when it scans, but that would be too logical.
 
One of my converter boxes (an Apex DT250) is now showing 35.4. As reported above, there is no video or audio. I marked it "not viewable" so I wouldn't have to skip over it when channel surfing.

The other converter boxes and the HDTV receiver seem to "know" 35.4 isn't supposed to be listed, so they don't show it to begin with. (None of the boxes show 14.8 or 14.9 anymore - not even the Apex.)
