Do you have a sat finder? I'm using a sathero 200 and it helps alot when you are struggling to find dvbs2 signals.
Or if you have the channel already scanned in, you can use facetime with 2 phones , go outside and tweak the dish until you get a good picture on your tv.
I am getting 103 at 67% and still can't get cozi in, Did they move this channel to a higher freq? I scan as 10750 and standard and still am not able to get cozi. Talk about annoying. heh
I have a few channels on my setup that my wife watches during the day that experience a signal drop and the channels break up so bad she says she can't watch them. By the time I get in from work, everything's ok. I've noticed some of the same channels breaking up through the day when I'm home on weekends, but along towards dark, they straighten up and come in. Not sure if I have an LNBF overheating in the sunlight and cooling down at night that could be causing the problem. Need to check that out too.
From what other experts have said here, what you are experiencing is due to using a dish that is slightly too small for the transponders you are trying to receive. Daytime noise interferes with the signal.
