Your statement is not very clear, no offense meant. What I gather is you want to upgrade to HD for your one HD TV. If you call to upgrade chances are Dish will need to put up a new dish. If you are in an Eastern Arc region, your 311 will not work on that dish. If you get a 1000.2 or new 1000.4 WA dish your 311 will work fine and get all your sd channels. That being said, you could get a 722 HD receiver which runs 2 tv's. Tv1 is HD and TV2 is SD, which would work for your situation and save you potentially $7 a month by not having the extra receiver fee (311) on your account. Hope this helps, but ask more questions if you have them and I'm sure they will get a proper response.
