Dave, W7DPW was asking about grid-distance formulas earlier: I stripped out
the bits of code I use in "MD", annotated it, and recompiled it into a
simple calculator. The procedures for extracting lat/lon coordinates from
the grid - and then calculating the distance (in km for the contest) should
be pretty easily to follow by looking at the .bas modules in my vb code. I
also compiled it for those that may want to use the program without a
compiler.
The source code and program are available through my site at
http://www.aerog.com/cgi-bin/dl/download.pl?file=gc
There are other, probably nicer ways to write up the decoding code but I
threw this together awhile back from some notes I found on the 'net
somewhere and it works pretty well.
DK3VN's website also has a javascript calculator online at
