Danster,
I musta been thinkin u were in Lincoln Nebraska, (what was I thinkin, LOL).
So your magnetic deviation should be 18 degrees. So adding 18 degrees to
180 degrees, when ur compass is pointed to 198 degrees magnetic,
it's aimed at true south. That should be the highest point in your dish's arc.
Here's a
modified polar mount diagram
and here's the
modified polar mount angles to use for reference when setting the elevation and declination while at the highest point in the arc (true south apex).
these are just screen captures from the satmaster program. Your declination looks like 6.23 degrees. So at your highest point in the arc (true south),
your mount's polar elevation should be 43.46 degrees, and ur dish's elevation (as measured at the face of the dish) should 6.23 degrees lower than that (declination), or 37.23 degrees. In other words, your lowering the face of the dish an additional 6.23 degrees to compensate for the fact the earth is round.
Since there is no satellite covering N.A. at 66 degrees Lon, what I would probably do is aim for True South using compass,
set the elevation and declination there. Then move over to AMC6 72W, Ku band, look for the NBC Mux
at 12053 V 6890. There's always a signal there and it's only DVB-S QPSK. Try peaking your feedhorn there. Once the feed is peaked, try peaking the elevation some more again, but leave the declination alone, since it was already set at the true south position.
Once that far, move to your lowest Western sat and ever so slightly rotate the mount on the pipe, to peak that sat.
Might have to go thru a few iterations, as described on the
alignment link, to get a feel for it. Most importantly don't get discouraged, 'cause like I said, every time I read that thing, I learn something new.
Once ya have it down pat, once or twice thru the procedure ya should be tracking pretty well.
