I should have used the term RF channel. I am talking about the actual channel frequency the stations are broadcasting on. Before stations went digital channel 4 was on channel 4. Now channel 4 is on UHF channel 35 and mapped to appear as channel 4.1 on your digital TV tuner. Most all other stations do the same now. Exceptions are channels 7 and 9 who still broadcast on VHF 7 and 9 but also are using other UHF channels to improve reception is some areas.Help me understand 'physical channel'. I have a secondary place in Castle Rock and just use a channel master flat floppy amplified antenna to get a few local channels. It's adequate enough but occasionally get pixilation. I am unable to get channel 2 and channel 7 as of last week. I do get 4,6,9,20,31 and all their low res subchannels and a few others which I am happy to get. I don't spend a lot of time at our Castle Rock location so I'm happy to get a few digital channels at 1080. Perhaps after today, I may now get channel 7? What exactly did channel 7 do today to get a better signal to their marketplace?? Should I expect to now get channel 7 in Castle Rock??
How does one receive a 'physical channel'? What is it?? Please explain. Thanks --Greg--
Others on this forum can probably do better explaining it than I can.
