As you mentioned, you likely do NOT want to call or chat with Dish as that could change the reception of your football programming. The OTA module for the receiver is great (be sure you have the antenna up, connect your OTA coax connection and have the power to the booster turned on) but if you have problems it is also not necessary. You can simply use the TV input to change between satellite (HDMI, I assume) to TV or Antenna, scan for the locals and watch TV that way. Yes, it is normal for your local Networks to say listed in your guide unless you called and had your locals changed. If you do a scan at TechWriter mentions above it will not over ride your locals just add more locals to the listing.
