Advertisements Hi I just got my new Series 3 HD tivo in and had a question about QAM channels. I am using basic cable channels 2-20 (filtered by the cable company on the pole) and OTA roof antenna. I did a channel scan and my OTA and Basic cable channels seems to come in great. I don't see any QAM channels? I tried tuning in 901,902,903,904,905 but nothing. I have Charter for cable and I'm in western mass. Maybe my QAM channels are filtered? How do I know where to look for them? Thanks!
