The angle between the true meridian and the magnetic meridian is called the "magnetic declination." If the north end of the compass needle points to the east of the true meridian, the declination is said to be east; if it points to the west of the true meridian, the declination is said to be west. 73 Darryl Bennett KD4CSW A proud member of the ARRL and the Bluegrass Amateur Radio Society -- FAQ on WWW: http://www.contesting.com/towertalkfaq.html Submissions: towertalk@contesting.com Administrative requests: towertalk-REQUEST@contesting.com Problems: K7LXC@contesting.com Sponsored by Akorn Access, Inc & KM9P ```
