I have 1 D12 receiver that searches for satellite signal everyday around the same time - about 4:00 or so. After awhile the signal comes back. My other 2 receivers work just fine during this time. Can someone tell me why this might be happening? Do I need to wait on freakin technician (no offense to technicians I just don't have time to wait for one) to come to my house? D insists that I have to wait for a technician. Any help is appreciated.
