I am missing:
4-4 and/or 26-4 UNCMX (although that doesn't count because it's a cable-only channel that UNC-TV has on Time Warner. I have it on QAM and it would be nice to at least put the channel on the guide so I can see what's on there without looking online.),
WGHP TV 8-2 (Antenna TV) - the channel is in the AM21 database but not "Attached" to the correct RF channel or something because it doesn't work. It used to, but doesn't anymore. I also have Antenna TV on 17-2, so I am not without the channel.
20-4 WCWG - 22/7 shopping, 2/7 county videos.
22-2 WLFL Country - TCN Videos, but it's available on WXLV 45-2.
43-3 WLXI TCT Family (not available)
43-4 WLXI TCT-La-Fuente (spanish TCT) (not available)
47-1 WGSR LP (not available, but I used WRPX 47-1 from the neighboring DMA and I can get WGSR to appear, but with WRPX's data)
So I am really only missing 3 and they're not THAT important.
