I just went to The List! (see tab at top) to view all Dish Network subscription channels for Abilene. Your SD locals are coming off 129, while your HD locals are coming off 61.5. Never heard of that bizarre combination before!I also have no idea what type of satellite they are going to use. They're probably going to use the two that are already outside. I have to have two for the Abilene, TX locals, or at least do until I get HD. Apparently, and correct me if I am wrong on this, but the Abilene locals come in on 61.5, along with the HD channels.
Right now, for SD, you don't actually need two dishes. You should have gotten a single 1000.2 which gives you 3 sats: 110/119/129. Since you have 2, I imagine you have a DPP twin on a Dish 500, and a 2nd Dish 300 (or another 500) for 129.
Here are my prognostications for what you'll wind up gettin once the installer gives you your HD locals. He will take down the 500 w/DPP twin and install a 1000.2 in it's place. (Should have been done already IMHO.) Then he'll swing your 2nd dish (called a "wing dish") around to point at 61.5 for your HD locals. The wing dish will get cabled to the 1000.2, which has one input and 3 outputs. So, after all that upgrading, you will have 3 DPP outputs to go to as many as 3 dual-tuner receivers.
This will all miraculously work, and you will be able to swap out your 322 at a later date very easily for either a 211, a 222, or a 612.
