Re: [amsat-bb] Pointing large dishes

["chris451" <chris451@xxxxxxxxxxxxx>]

I have the regular polar mount and I have elevation trim (put another activator where the elevation screw was) but I also have polar rotation but you will need at least the two motors to track it most of the time.
Elevation varies quite a bit from day to day. 
Usually, I just point down about 6 degrees from normal tvro satellites. I always trim both vertical and polar.
Vary rarely do I use my vertical axis rotation on AO40.
Oh and Sprint moved from 1951 to 1955 mhz so now that
jams my downconverter on its image so I either have
to move the converter crystal or put in a 40 db notch on that freq. 99% of the erratic, slow or unpredictable drivers, have a cellphone on their ear.

Subject: [amsat-bb] Pointing large dishes

 have recently acquired a 10' TVRO dish and would like to use it for AO-40.
I recall that when some folks were first trying to use the large dishes the
claim was made that AO-40 closely followed the ecliptic and that leaving it
set as a polar mounted system would work.

I wonder if anyone actually made that  happen. I am willing to engineer an
az el system but there will be a lot of adapting to do.

Any help or ideas would be appreciated.
