HI I have a dtc-100 and have directv and all that. I have a hd set. I bought an antenna today to try and receive my towns local OTA Digital Broadcast... (Channel 16 NBC) So I hooked the Antenna to my Antenna A input of my DTC-100. where do I go now? How do I find my channel? I did a search but it turned nothing up. Anyone offer any insight?? Oh and Im only about 3 miles from the tower using a RCA Indoor Ant that says it can pick up High Defition signals.. please help!!!
