That's typical of two receivers connected to the same splitter. It's why splitting a line between receivers doesn't work. Each receiver needs a cable directly to a dish or multiswitch. A multiswitch requires more than one connection to the dish.
Hello Graywolf, I have a standard receiver from a Trac Star satellite unit on our new houseboat. Great picture, everything works well until our neighbor down the dock turns on his Direct TV receiver and begins changing channels. I change his and he changes mine!!!!
I've switched receivers from other TV's on the boat that aren't affected where they were, but didn't help when reconnected with the main TV in the salon.
I'm guess that you're using the "RF Mode" on your remote control, and your neighbor is using the same code with their RF Remote. Under the "Settings" menu you can change the remote's RF code. That should solve your problem.
