Re: [Repeater-Builder] ATSC pilot frequencies for sig. gen. alignment

I think AM stations have tighter frequency requirements. I think I read some where it was supposed to be + or - 5 hz, of course that is only at 1 to 2 MHz which is still 5ppm stability. Isnt CDMA supposed to use GPS locked rubidium standards? See i you can find aa control channel in the 800-900

Except that you need to despread the pilot. The good news is that some companies make saw correlators for the pilot. Bit of work regardless. DCFluX wrote: I think AM stations have tighter frequency requirements. I think I read some where it was supposed to be + or - 5 hz, of course that

OK, now that NTSC video is gone, so are my handy local video carriers that I used to use to check the frequency accuracy of my signal generators. However, I understand that there are pilot carriers buried within the 8VSB DTV signals that can be used for the same purpose. A couple of
