Hi Shawn:

Thanks for your reply.

Please excuse my simplistic questions, but this is a completely new world to
me.

What is WGS-84?
I use a Holux M1000 receiver.
I think also that I found that within the Loadstone menu system that there
is another way of setting altitude calculation - is this right, and if so
what effect would this give?

The altitude uses the wgs84 datum. This may be different from the datum for 
your area. Some receivers will give you the difference between the local 
datum and wgs84 and if so then loadstone will factor it in to the 
calculation.
