Hi, been here a while, just don't have a lot to say.
The quoted elevation was only 1 degree worse for 61.5, 27 vs 28 for 148, as I remember. The worry was a house or worse a chimney. Did not have a good azimuth measure, so all OK.
I did have to move the base because of a tree. Then I had to search the sky. The D500 with one LNB was pointed higher by the original 148 install and was needed here, too. I leveled the short pole but either the dish has a geometry problem or the pole didn't stay -- it is too short to check and I don't want to lose the final pointing.
For anyone trying a scan work in 2 deg elevation steps and scan your azimuth. Once you get any signal you can then home in on it. The wrong satellite may be indicated. Do the check switch after you get a good signal.
Thanks, good to know some else has the KRQE problem with a 921. I've not gotten a response on that from the national boards.
