does anyone know what the threshhold is for signal strength causing dropout/pixelation? I get good signal from all satellites (90 to 100%) except sat 99 is about 60%. All my channels look ok right now, I have choice plus package but I don't get locals yet. Supposed to get them next month here in cen arkansas 72015. I think they will be coming from sat 99?? will it be a problem?
