shen, think about it for a minute. *Just ONE* of the issues is that a radio
compass is aligned using a magnetic compass.

think about it? how many mag compasses have seen on boats that are accurate to
2*?

Think about it more. How many helmsmen on sailboats have you seen that could
hold a course to 2* over any period of time?

Think about it. the error of the mag compass reading TIMES the error of the
helmsman gives the potential error UP TO THAT POINT. Already, you are
waaaaaaaaaay beyond 2*. waaaaaaaaaaaaaaay beyond.

Think about the additional errors associated with just the radio compass itself
and its usage.

think about it, shen.

Think.

....And you haven't come up with one fact to say it can't be better than 2
degrees, other than some dumb comparison to taking a bearing on sounds (a
known
no-no), and have shown you don't know the basics of piloting, when using a
compass.
