Good evening all, I recently purhased a Dish 500 plus + dish to be used with our RV. We had been using a standard 500 but would like to view HiDef and international channels. I have a Super Buddy for alignment. For the life of me I cannot seem to find 118.7 or 129( I purchased the single LNB to add to this dish systemfor 129). The instructions say to align to 119, check 110 and then align 118.7 by using the signal strength bar on TV. During check switch it sees the 4 LNB's but only shows 119 and 110 as valid? Any insight/education you may provide greatly appreciated. Pete in NC.
