TRUE NORTH QUERY

[Pat Barthelow]

Gary,
Call your local airport control tower or FBO, and ask them what the 
magnetic declination is for your area.  This is the difference in degrees 
between true north, and magnetic north.  It drifts slightly each year, 
but not amounts of concern for antenna pointing.  In Richmond, VA a 1965 
map I have, shows the declination as being 13.5 west; That is, true north 
is really east of where the compass needle points by 13.5 degres.  Annual 
change in 1965 was 5 minutes westward per year.
Good Luck, de Pat, AA6EG  aa6eg@tmx.com
