So, I have a Dish 1000 on the roof pointed at 110, 119 & 129. Installer came out and put another dish up pointed at 61.5, and wired it into the Dish 1000 LNB-set. Relative signal strengths are: 110 & 119: in the 80s 129: in the 40's 61.5: in the 60's So, for example HISTORY HD channel 120 is carried on 129 and 61.5, but it always says it is coming from 129. I'd prefer to have it (and all other duplicated channels) come from 61.5 since its signal strength is so much better. I've hunted around in the setup menus and cannot find a setting for that. How do I do it? Thanks!
