I've tested multiple qam tuners on multiple PCs with the same results. Channel 5.1 (Fox) is identified from the scan. 2.1 (CBS) is not identified but can be located at 71.1025
4.1 (NBC) and 7.1 (ABC) should be on channels 72.1027 and 73.1029 respectively but are not being found after channel scans. Here is the channel data I'm using: http://www.silicondust.com/hdhomerun/lineup_web/US:07981#lineup_8347993
I'm not sure why 72.1027 and 73.1029 are not listed after channel scans. Any information or suggestions would be appreciated.
