You can go to my website's Birmingham page and see what each subchannel is carrying, too.
WALA is listed as 10 in the database, probably the issue. The AM21 database is reliably unreliable. That is, the database is there. Any channel changes, affiliate swaps, etc within the existing channels, it will update when Tribune does. Incorrectly entered (such as WALA it looks like) and newly added subchannels just are ignored.
This is how WALA is entered in the AM21 database. It should work now, if it didn't before. Try resetting it. I am curious to see if it works now for you.

There has been a slight update to the AM21, it seems. RF channels don't matter as long as the signal is there, it will match it to the PSIP channel. Here in the Greensboro NC DMA, we had an issue like you have with WALA. Our Antenna TV on 8-2 was not correctly entered into the database so it wouldn't show up, they had the RF channel wrong. The database still lists it incorrectly. That seems to indicate that only PSIP matters now. That might help WALA as I see it's RF9. Also, you can add as many secondary zips as you want, allowing you to "steal" listings from other cities. As previously stated, I live in the Greensboro NC DMA. I have Raleigh NC as a secondary DMA. Then, I added zips from Indiana, Memphis, Vermont, and Ohio to fill in my missing subchannels. The guide data is for the "other" channel, not your local channel, but it still allows you to manually tune to a subchannel if you happen to like it. At the time that all of this was noted by other forums, Telefutura was changed to Unimas on channels in the database, showing me (At least) that some maintenance to the AM21 occurred. At this time, the Genie system stopped scanning in the missing subchannels in some marktes (like mine). Also, all CBS logos were removed from the AM21 channels. Of course, this is all speculation but there definitely have been changes recently.
For example, Birmingham is missing 6-2 Bounce TV. If the poster lives near Huntsville, for example, s/he should input first a Birmingham zip, then a Huntsville zip. Then, adding a zip code from Bluefield WV will get you 6-2 to appear in your guide, as WVVADT2. It will show WVVA2 (CW) guide data but when you tune to it, it will be 6-2 Bounce TV.
I didn't believe that anything had happened with the AM21 database until I noticed our 8-2 working. I think noticed they had changed my local Unimas to finally show as Unimas. I refused to even try adding additional secondary zips as it seemed so stupid for a while but I eventually gave in and it worked for me! It's a time consuming process to add so many secondary zips as you have to completely re-set it each time but it's worth it if you want the missing channel. Of course, if you don't want the missing subchannels, just set it up once and be done with it.Edited by ejb1980 - 8/10/13 at 6:20pm
