I recently added a second HDTV to my setup. I requested a pair of BBCs from D* and connected the new TV to my existing R22. Before I added this TV I had two of the lines from my Slimline 5LNB going to my HR20 and the other two to a powered legacy 4X8 multiswitch that fed all of my old legacy MPEG2 STBs as well as the R22 and the world was a happy place. When I added the second HDTV I connected the WB68 that the installer had left for me when he first installed the dish 5 years ago. I ran two of the WB68 outputs to the HR20, two to the R22 (with the BBCs) and two to the 4x8 multiswitch. Two outputs are unused. And for the first few weeks the world was again a happy place. Recently I began getting intermittent 771 errors on Satellite in 2 on the R22, only on HD channels, only in the evening and not every evening. As a troubleshooting measure, I moved the cables for the R22 to the two previously unused outputs on the WB68 and the problem persisted. Then I swapped the satellite connections on the back of the R22, BBCs and all between SAT1 and SAT2 and sure enough, the intermittent 771 errors moved from SAT2 to SAT1. Tonight I am going to swap just the cables and leave the BBCs in place and see if the problem follows the cable or stays with the BBC as a final measure to isolate the problem. I am however more suspiscious of the cables. The cables from the WB68 to my DVRs are pre-fabricated 100' RG6 cables so it's a pretty substantial run but I've had no issues until now. I am not so naive as to not realize I may have just been lucky up to this point and I have now introduced a non-powered multisiwtch into the equation. I'm thinking that since the problem arose when I went to HD on the one DVR that it could be a problem with signal loss over the length of the cable. But since the problem is confined to the HD channels I cannot rule out the BBC (at least not yet). I was looking into adding a Power Inserter/Polarity Locker. The Sonora HRPID1422A is frequently referenced but when I search Solid Signal's site it isn't found any longer, links to it from other threads in this forum now return just general multiswitch search results and I am suspecting it may be discontinued. What I do find is a Sonora 5SATPL-T SlimLine Ku/Ka Polarity Locker Power Inserter which appears to be a newer version of the same thing. Would this be the thing I need if in fact the problem is isolated as signal loss over the length of the cable? I also found a similar item from DirecTV a SR 6SPI DIRECTV Power Inserter but it is more expensive and quite frankly...it looks cheesy and doesn't have the "brand name reputation" of the Sonora. I still hold slim hope that it is in fact the BBC that is bad, but in my lifetime I have not normally been that lucky. I invite the comments and opinions of this learned community. Oh, and I am not retarded.
