bigdan, okay, here's the next question. Is your plan to keep the two 301's connected in addition to the 522? In other words, 4 different tuners pulling in different signals at the same time?
In that case, the twin LNB on the dish won't do it. You'll probably have to get some new hardware on the feedhorn, like a quad LNB. If you still have the Dish 500 installation booklet, there are easy to understand diagrams in there for different configurations as more receivers are added.
If there's a friendly DishNetwork retailer in your area, you might be able to get some free advice + purchase whatever extras you need for a do-it-yourself job. Or, bite the bullet and invite an installer over for a house call. (If you're not sure who the retailers are, call DishNet customer service at the standard 800- number. They keep a current list.)
