[TowerTalk] True North, astronomical methods

[sabrams at nycap.rr.com]

In negotiations there is a difference between one's "interest" and one's 
"position," the former focussing in what you think the other really wants 
and the latter focussing on what he asks for----So, do you really want to 
know where North is so you know where North is, or do you want to know where 
North is so you can calibrate a rotator?  If it's the latter, there are many 
ways to calibrate a rotator including many that don't need to know where 
North is.  Perhaps that ought to be the subject of the thread instead of the 
interminable "Where is North?" 73  Saul  K2XA
