Subject: Re: [LML] Re: Compass calibration

Speaking of calibration I have been meaning to ask a burning question about T=
ru Trak a/p.  mine is confused about heading.  It is usually 30 degrees or m=
ore off of actual heading.  Is there a calibration mode for the A/P?

My device not infrequently messages that it wants to shut off and some times=
 it does.  At other times it has introduced errant output to the point I hav=
e to disconnect to avoid making unwanted attitude changes.  A few times I've=
 had it not want to let go and I have had to do the equivalent of popping th=
e c/b. =20

It seems to be doing this less and less and maybe the a/p heading is gradual=
ly getting closer to the Cheltons. =20

Any thoughts?
