I don't want the R16 in dual. I never use it except for the second football game on Sundays. I checked the PI and it is 21 so I can throw the 29 volt one at them as an idea. They did go through the attic at least once (day 1 for sure when he changed out the MSPLIT8R0-01 (he left the old one so I am looking at it) and changed the LNB on the dish. He said all connections were tight. I am not sure what else at this point either. Not to mention the frustration factor!
