Here are the results with the skew at -45/40, -90/90 and 0:Just a further note. I will be unavailable again until Sunday night, hopefully, someone can step up to help.
Anyhow, check at 45 (both + and -) and check to see (via Lyngsat) whether the transponders you are scanning in are any of the vertical transponders. If not, do 0 and 90 (after deleting channels/transponders) and check again whether you are getting any vertical transponders. If you don't it probably means either the polarity (or skew) is not changing (I would think you should be able to see the polarity changing at the dish, but since I don't have a C band dish and that type of setup, someone else may be able to confirm what you should see when the polarity is changing) or there is something else wrong.
If you do scan in any of the vertical transponders, but not 12084, then try to peak one of the vertical transponders by adding/subtracting a few degrees off the polarity. Once you get the best signal on one of the vertical transponders, re-scan again to see if 12084 comes in. If not, you probably have to adjust the dish east/west or maybe even up/down slightly to get the transponder to come in (again, using one of the transponders you are getting to peak the signal). Good luck! Hopefully, when I return Sunday night you will have got it to come in!
