wow, out here in the northeast of PA our dtas are coax out only... no such creature as an hd dta. Also no such package as HD Limited Basic without paying 9.95 for a full blown HD Digital box in addition to the fee for limited basic. We are also currently 100% digital, no warning messages, just snow on analog. A qam tv will still pick up about 30 channels, but that is not advertised as "intended to happen" and is generally frowned upon by comcast in this area. all locals come in sd and hd on qam, and a few other channels that arnt really worth watching.
Like i said in my post a few back, when i was working out of system in a 'vacation town' called eagle's mere pa (it snowed there last april when it was 60degrees not even 30 miles away lol) that place was analog only, and my first time doing installs for a system that had no digital support at all. (easy as hell, but still strange) had a few people cancel saying what do you mean i cant have hd. Sorry comcast doesnt support it in this area lol. I have worked for them back when you had your basic 70 in analog however, so ive been doing this a while, its just crazy to see how spread out comcast really is with their "Xfinity upgrade" or "digital conversion" across the country. And hell I would love to work with the X1 stuff which is already being phased out in certain markets for x3.....
