I am moving and want to do a dish mover and upgrade from my older hopper to the H3. I am getting a Samsung 82 inch 4K tv for my main room. I will get three additional Joeys. One will be wireless. Questions 1. How can I be sure the new hopper will be able to access the important older recordings on my existing three external hard drives? Are these locked to the receiver ID or my account number? 2. Do I need to transfer my recordings on the old hopper internal drive to an external drive prior to changing out the receivers? Or can that be done Hopper to Hopper during the install? 3. Does the remote on a Joey talk to that Joey or have to transmit all the way back to the main Hopper? That's about 75ft in my case and thru two brick walls. 4 What is the expected range on a wireless Joey? Would like to put it in a detached garage about 65ft away. Thanks for the help.
