Is it a CW carrier (Continuous Wave), or digitally modulated 64QAM / 256QAM ? Obviously it's not NTSC Analog as all you see is snow. |

| continuous wave as my tv does not detect a digital signal. when i type 122-1 it does not even go to 122-1 it just stays on the current channel.
what is wierd is I also have: 94 test 256qam blank carrier 100 test 256qam blank carrier 121 test 256qam blank carrier 125 test 256qam blank carrier
it used to be on channel 94 when my cable system was 750MHz then it was moved to 116 then where it is today. |
