If you upgraded to the sj then they would've replaced your solo node with a duo hub not a solo hub. So you will need to switch it out for a solo hub to run the hopper3. Unless someone on here has different info, I am to understand that moving forward, the duo hub will only be used for pre dpz equipment.When I had my SJ put in the upgraded my LNB to then new hybrid version and replaced my node with a solo hub. Can I order from dish depot and unhook the H2 and SJ and hook up the H3 without any other changes?
