Dish size - mesh 9 ft; receiver - Motorola DSR922; LNB - 13 K BSC211 DMS international; If I am on C-3 600 and go to G3 502 it will not show the NBC channel. Instead it shows a frozen picture from the HGTV channel. It does the same on all channels on G-3. Also on W-3. Sometimes, if I unplug the receiver, wait and then plug back in, it will work.
