Logit!
LOGIT is a computerized log book for ham radio operators. It will store endless contacts, allow you to search for previous contacts, and also print them if you have a printer. LOGIT is a MS-DOS based program that will run in MS-DOS, Windows 3.x, & Windows 95/NT.
LOGIT also has a world wide call sign lookup program. If you have ever done any "DXing", you've probably heard ham operators and couldn't figure out where they were from. With LOGIT, all you have to do is type in the first two characters of their call sign and LOGIT will tell you what country and/or island they are from.
LOGIT is available as a shareware program. This version is the complete working version. So go ahead and try it!
