Does anyone have any ideas for help? I tried to help a friend tune in a FTA system recently. We were able to get a strong signal on several sats but could never get ansy "signal quality" so no picture. The tape that came with it said that we were to tune in on AMC4. Is that the best one for a fixed dish? Is there a little "trick" that we weren't aware of that kept the quality from kicking in? A setting or something that we don't kow about. We had signal strength on 80-90 percent.
