Today I heard a carribean dxpedition for the cqww concerned because he 
wasnt sure how to adjust for the difference between true and magnetic 
north...Is there really a big difference?? I think for my latitude its 
around 4 degrees..Should ones antenna be set for true or magnetic north?? 
Also  a W0 on one of the reflectors( I hope this one) mentioned that 
while experimenting with a 1/4 wave sloper they got a significant signal 
strentgh difference on rx while adjusting the angle...what does work best??
wouldnt it depend on the incoming signal angles?? wont it change as 
propagation condx change??73 Jamie WW3S
