Doing so the security checks are good. When posting to OLC, OLC
checks the file assuming it came from a Cambridge 302 (I am using a
Model 20) and fails the security check. Can someone tell me if they
have been able to get a model 20 posting to OLC. Thanks!

The cheapest, easiest way to do it if you are using windows is he
http://www.abqsoaring.org/misc_files/CAI_fix.htm

Its a simple little utility that does everything for you except
downloading the .cai file from the logger and actually posting to the OLC.

Dave,
My process is:
1) Download cai file
2) run the utility given in your link. All the security checks are good
and the igc file is ceated.
3) I post the newly created igc file to OLC and they run their checker
against it and it fails when OLC checks it. (see above)
