The OLC site incorrectly has stated for months that the conversion
software available from Cambridge produces igc files valid for olc.
The OLC site currently has a news item that this isn't correct, but
does not offer the solution that works.

I have successfully produced valid igc files from my Cambridge model
25 only by using cai2igc4olc.exe -- this is available at
http://www.abqsoaring.org/misc_files/CAI_fix.htm

Thanks to Carl Ekdahl for doing last year what Cambridge cannot do.

cai2igc4olc.exe must be located in the directory in which the .cai
file is located -- I believe it's safest to copy the .cai file to a
working directory in which cai2igc4olc.exe is located...

Now...if someone would teach me how to point friends to flights I've
uploaded. I'm too stupid or blind to see how to do this.
