LORAN to GPS Conversion

I occasionally recieve requests from people who want to convert between LORAN C and GPS coordinates (LAT/LON). For reasons which I discuss in my article at http://www.execpc.com/~bbaillod/navi.html , this conversion is not advisable and yields a nonstandard error of 0 to .5 miles. The error is particularly pronounced in the Great Lakes due to land mass propogation errors inherent in LORAN C. However, I have located a decent freeware program which will perform the conversion to or from GPS or LORAN C for those who need an approximation and don't have the functionality in their current GPS or LORAN. The utility is a DOS program which may be downloaded as an executable. When the executable is run, the program is unzipped to the local directory. I have tested it and it appears to work at least as well as the conversion on my GPS. The utility can be downloaded at:
