Re: Now HERE is a stupid question...



Hi Timothy,

You need to use true north as the tracking program doesn't know your local
variation.  If you are close to the ocean, a nautical chart will give you
both the variation and the annual change since it was published.  I assume
there are similar land map data.  Or a quick call to your local airport or
FAA facility should get you the answer.  Here in the Virgin Islands the
variation is about 13 deg. west.  Anyway if you get it within a few degrees,
you'll be fine as even the most directional antenna has 15 degree beam
width.  The tracking programs usually bring you within 3-5 degrees to
minimize searching back and forth.

I prefer the NOVA tracking programs - Very flexible and both easy and fun to
use with good documentation.  But most any of them work fine - just be sure
they interface with what ever tracker unit you use.

73's & good luck!

Hope to meet you on the birds.
