Hi!

I recently bought a Holux M-1200 bluetooth GPS receiver to be used with my
PDA. It sort of works - but has one "minor" problem - when I curve, it often
can't acquire good signal and gets really confused. Ofcourse I could just
avoid curving, but living in a very flat country, it's the only way I can
stay up.

Has anyone else had these kind of problems with the M-1200?

Any suggestions for a GPS receiver (preferrably bluetooth, but CF could be a
possibility)? I like the M-1200's ability to do 5 updates/sec. and I'd like
the new one to do that too.

You could experiment with where you put the bluetooth GPS in the
glider. Or, if you use a data logger you could see about taking a
feed from that to the PDA - that will mean that you can be absolutely
sure that your trace won't include any airspace infringements!
However you might well not get 5 updates/second going down that route.

I have great results using a 'freedom keychain GPS' into an IPAQ 3790.

but I don't think the 5/sec. update is going to happen. Nice $100
backup GPS though.
