I am using my system at home and it works fine with a Slim Line dish with 1 HD DIRECTV receiver and 1 HD-DVR receiver.
I want to use the plain HD receiver in my RV with a Wineguard RD-9046 18”x20” Oval dish. (When used I get the 771 error.) I’m getting about 15 volts from my receiver to the dish, getting a strong signal using a satellite meter, recruited help from fellow camper that have dishes but still could not find a satellite. Do I have to change any programming in the receiver to except the different dish or satellite? Is SWiM and a multiswitch needed for a single reciever?
Thank you for any help.....Old dogs have a hard time learning new tricks...
