Sorry for the long question. I've been a longtime Dish customer but have remained old school by purchasing my receivers and not moving to the Hopper. The main reason is I have a home in the mountains and I'm able to run all three receivers through one subscription. I'm using a 922, 722 and 612. I'm on my 3rd 922 and this one is ready to die. I've had no luck finding a refurbished 922, only 722's available. If I replace the 922 with a Hopper would I need to upgrade my LNB? Can I run the Hopper and my 722/612 on the same dish/lnb? Any suggestions on how to manage two locations on one account? Thanks in advance for your comments.
