Dear all, I am just about to stand up my tower with everything ready to go.yippee..at last.. I have Azimuth and Elevation Positioners M2 OR2800PDC and M2 MT1000 see www.vk2sn.com <http://www.vk2sn.co
Sean: Here's a page from the US's NOAA that allow you to calculate magnetic declination for any location on the planet during the near future (it's a slowly varying value due the the daily wandering
Calculating the difference between magnetic north and true north is one way. Here is another way. Go here and enter your QTH cordinates. http://aa.usno.navy.mil/data/docs/AltAz.html For the day you a

Zero degrees is north, which can be found by locating Polaris in the (clear) night sky. Polaris is the star at the end of the handle of the little dipper. The front edge of the big dipper points towa
Being in the Northern Hemisphere makes it quite easy to do at night IF the sky is clear. Find Polaris .. the North Star. Stand so you can sight Polaris THROUGH your tower. You will be standing due SO
Sean, What you need to find is the "deviation" (the difference between true north and magnetic north) at your QTH. Aeronautical charts are accurate, and do contain information about deviation. If you

Magnetic North wanders around in a rather large circle and changes between a half and a full degree each year (in some areas) in others it may be quite stable. In the NW US magnetic north is quite mo
The position of the sun at "local solar noon" is always on the N/S line, what changes over the year is the time offset between local solar noon on a particular day, and mean "noon" averaged over the
Go to your local university or engineering book store and buy a recent copy of Ephemerus (think that the spelling is ok). In there you will find all magnetic deviations, including the one that applie
