There are a few situations like that where someone else owns it and gave the keys to Sinclair so in reality its a Sincalir station.
The St Louis case the 2 stations have no association at all which makes it interesting as St Louis can see Ring of Honor on 2 different RF stations (the ABC station and Comet)
scrap it and get a Tivo series 3 with lifetime
Honestly Directv wont add anything to the database and wont
There is a monkey shine way of adding stations to the database by using other areas zipcodes that have the numbers in the database but it involves looking at the database and finding what station in a different market that (as example) has a RF48 and a 6.3 together to view it (even though in most cases it wont be the same guide info). So then they load ANOTHER zip into it that has AntennaTV info so you can see at least what is on
Confused yet? Best bet is to look in the Directv area on some threads
You only need to match the OTA PSIP channels, RF doesn't matter anymore. I force in MeTV on 5-3 from Texas and the RF isn't close.
But yeah... Cumbersome and dumb. I am lucky that all my local (USA) channels and subchannels are in the database, if you force MeTV on 5-3. Other than the wrong call letters, you'd never know. In NC, I had to force a lot of subchannels and eventually, I just said screw it and made a custom list on titan tv to see what's on the subs. Now I do the same to see CBC Montréal.
