During the past week I am encountering brief (non-weather related) signal loss on at least three HD channels (CNBC, FOXB, FOX) all of which are on SAT129. This occurs on all 4 of my DVRs(622,622,722,722) and is not a weather problem. The error message is 206-signal loss. If the up or down channel button is punched and then immediately returned to the original channel the picture has returned without a lengthy rebooting process as in a weather related signal loss. The Dish technician could not offer any explanation or solution. Is anyone else currently encountering this problem and does anyone have a solution?
