I have been trying to get a 311 receiver to lock-on in my motorhome which has a single LNB antenna (Winegard DM-RM46). At one point it almost locked on to 110 but failed. I have used a VIP211K in the motorhome and it worked. I ran the check switch test and it indicated there were less satellites available and then a box indicated if I wanted to save the new info which I did. Now the check switch function indicates no satellites available. All X's in all boxes. Is this something DISH will have to reset for me?
