It might be worth adding that your example will be the opposite for folks on
the east coast with a minus declination. If the instructions are followed in
the link below, it will be possible to know your declination, if any by
entering your zip code.

Here at my location in California the magnetic declination is approx 17
degrees. I simply point or adjust my rotor controller to indicate 17 degrees
and adjust the antenna(s) to point *Magnetic North* using a military
compass. It seems to work just fine every time for every antenna and rotor
combination. When I rotate my antenna to point true north according to the
rotor controller indicator it then points to true north. Thereafter my
rotor/controller/antenna ensemble pretty accurately points where I want them
to point. Simple but it works...and works well. Try it...great for Field Day
operations and mountain top VHF contests too....!  :-)

HEY!!! Did I hear someone asking how to determine "True North"?!?!?!?!?  It
was kinda hard to hear over the S-9 Hoot Owl thread and +20 dB generator
noise right now... :-)

As everyone knows, there's been enough threads regarding finding "True
North" to weave a fine pair of socks... But that aside, you can use Goggle
Earth to determine "that direction" using their tool to zoom into any
location in question. The map defaults to N/S orientation.

I verified my antenna alignment by picking a known object a half mile away
from my tower. In my case it happens to be the east side of a church down
the road. Not all areas on earth have been mapped with high resolution yet,
so this technique might not work for everyone.

Credit goes to my late father who taught me this "lining up" technique when
we were fishing on Mille Lacs Lake (about 27 miles across) locating specific
fishing spots. This in the 1950's, way before GPS.

Try the above link to work out your Declination, there is a link on the
site to a calculator.  I doubt you would be as much as 30 degrees off
true north, I am 18 degrees here by SFO.
