I have two D* receivers, one H10 and one HNS HDVR2. I'm having trouble getting the even transponders from the 101 satellite (18v connection). The problems are intermittent and half the time I get the "Searching for satellite signal (771)" error message. I've tried everything I can think of... from replacing the LNB, the RG6 connections between the LNB and the MS, and resetting both receivers several times. Is it possible that my MS is manfunctioning? D* doesn't seem to have an answer for me and I'm trying to avoid a service call.
