Re: SNR on digital cable. Hmmmm.... seems like we were all wrong...
Despite reworking my cables a few weeks ago, the problem recurred.
Anyway, a Comcast tech was at the house today to hook me up for digital voice.
I asked him about my problem with the HD channels having sound cut in and out occasionally.
I also explained what I had observed in the STB diagnostics page ("Good" SNRs for the digital channels (in band), low AGC value for the OOB combined with a "Fair" SNR for the OOB). He said that the signal may actually be "too strong" and swamping the input amp on the STB. He said to try adding another splitter to the signal to see if it fixed the problem. So I rearranged my splitters to move the HD box downstream of another splitter.
Guess what - the problem seems to be corrected.
