In reference to your signals.Cool. But your US signal's a little high. In my experience 50 is the cutoff and anything higher spells disconnects until fixed. Also, are you on Cox, cause I don't think Comcast serves AZ. Cox does if memory serves.
Comcast is all over AZ now. I signed up with them 5 years ago.
I bet they don't serve places like the Navajo Nation though.
Are they? I thought that was all Cox domain. Are you enjoying Comcast, then?
