My installer got the hoppers up and activated but then powered up both Joeys. Oops, 4 more hours of tries by this tech, 1 more tech visit and 2 new Joeys later and I'm now OK except both Joeys are linked to the same Hopper. As a result of just powering up both Joeys they both got stuck in a state where they immediately tried to link to a Hopper and no amount of magic reset sequences suggested in this forum or from Dish would work. If I ever see a 1303 message again I'm gonna scream.
