Welcome to the ProLog Website.

Datamatrix has been in business since 1991 as a manufacturer of quality software platforms for Amateur Radio applications. Having consistently maintained a 4.8 out of 5 on eHam.net the ProLog logging program has established itself as the premier product in this category of Amateur Radio software.

Complementing the ProLog Logger is our comprehensive QSL Route Manager Database, a voluminous reference for over 110,000 DX Stations and their managers. Also offered is our CallMaster callbook database containing the complete US and VE callbooks together with most of the DX callbooks from around the world. Couple the aforementioned databases with your ProLog Logging System and you have an unbeatable callsign reference library.

Our CallMaster database is the most comprehensive call sign reference available. Don't purchase a callbook CDROM product that does not provide monthly updates. When you purchase a callbook database you want to make sure that the information contained therein remains accurate from month-to-month. Your purchase of the CallMaster callbook product also includes  a six month access privilege to our FTP site where you may download the latest US/VE and DX address changes and additions. The merging of that update file will ensure that your CallMaster callbook database will always be accurate and up to date with the latest US/VE/DX address information.
See our "What's New" page for more information.
