Doug et al.

Here is an image in png and pdf formats (roughly 4Kx4K pixel base image).
Hope it helps.

Once upon a time, I thought someone had distributed a compass rose image
suitable for printing (PDF) that could be used to make a compass disc
attachment for a 10GHz tripod. I can't find it any again. Does anyone
still have the file or know where to look?

Most of the files I have found have problems in some regard. Small
images, increments in the wrong direction, markings in 90 degree
quadrants, doesn't have degree markings, etc.

I think the ideal would be a PDF file with three pages. One page being
the full circular compass rose, the next two pages being 180 degree
sections that can be cut-and-paste together, all images maximum size for
the page. The PDF image could be resized at print time to fit letter
size or 11x17 paper or made smaller as needed. I suppose it would be
possible to add mirror image files suitable for "look thru" use too.

Has anyone got a link? If we do get a file, perhaps it could be put on
the NLRS web site, assuming there is no copyright issues.

OTOH, a full compass rose is probably not needed for most operations. I
was thinking it might be handy for next year's Lake Superior operations
if I could accurately adjust by a number of degrees to go from one
bearing to another. i.e. A map or computer program says my bearing must
change by 6 degrees to switch from Michigan to Ontario, but even a short
compass section can handle that.

A full compass rose would be most useful if I was going to use the sun
shadow technique to align a compass rose to the actual solar position,
then turn the dish to the correct bearing for the remote site.

I also considered it might be easiest to just buy a plastic or metal
protractor if I could find one at the office supply store. But I expect
a suitable large one to be expensive, while a printed image on an
overhead projector transparent sheet is quite a bit cheaper.
