Had 211 and dish 1000 installed yesterday. Seemed to go ok. Saw ech using point dish function and had good signal strength. Later in the day I notice that I get either a scrambled or no signal at all on most HD channels above 9424. Looked at signal strength as told by Dish csr and it was at 47. They have a tech coming back out tomorrow and I get to waste my whole afternoon waiting for them. Is there anything I can do to help this myself, short of going on the roof. The CSR had me changing transponders but I am really too much of a noob to know what that does.
