I have been tinkering with FTA Tv (Coship & Satworks 3618 & 3668) receivers for over a year. I daily check this site and enjoy all the postings and have learned so much from them. Trees in the back yard limit what I can receive, but I have enjoyed the FTA offerings. I usually don't post but am frustrated with the Satworks 3668 since for the past few months it has been freezing up on me. Some days it does, some days it does not. I have to unplug it and plug it back in to get it going again, and this could keep on every 5 minutes or maybe every 15 minutes. On some days, the problem does not happen at all. I have Ku and C band signals coming in, and the C band is NOT affected at all. I have 4 LNBs connected to the receiver, and G10R and AMC4 give this problem, while IA6 and C band AMC1 do not go out. Is there an easy fix to this or could it be a defect in the Satworks receiver or software...any tips appreciated.
