I did it! The Winegard 2076 and Geosat Pro PLL SL-1 arrived yesterday. I had to modify the non-penetrating mount my landlord gave me to put the new footing on it and spent some time getting the stand level as it sits on dirt (this is West Texas). I had the elevation right on target and within a few minutes found the correct azimuth. The skew does not seem to change even if I turn it way off but of course I set it as recommend. I am getting a SQ of 99 and SS of 91. One member has suggested that those are labeled backwards.
Activation on the computer was painless and I soon had service. I set some favorite channels and as has already been posted one must first hit guide and then the small FAV button to get to the favorites list. I took the $50 package and of course $4 DVR fee.
There is no indication of which channels are HD and which are SD but I can see a difference even on my 40 inch Sony. I would say the HD channels are as good as other services I have seen but not quite up to the level of the OTA major networks. The SD channels are at least as good as the local sub-channels ( Ion, Quest, Escape and such). It certainly meets my needs but I can see that it would not satisfy those looking for the most pristine quality on a very large display.
I am not planning on adding in the local antenna signal at this time. In the future I may look into a duplexer (spelling correction will not let me type that correctly!).
All and all, a successful project.
