I know there are probably threads with the answer to my question but so far all I have found are similar ones that aren't leading me to the answer. Here is what I want to do: connect 2 HR24 receivers to share programming (MRV/whole home) My sat has 4 wires coming out of it right now. Currently I have an existing HR24 and a SD reciever that I am upgrading to the 2nd HR24. I guess what I am asking for is a list of the parts I need to self install. I have heard the HR24 has built in DECA so I wasn't sure if I needed to buy one or not. and do I need a swm8 for 2 rcvrs?
