Welcome to the ProLog website. 

DataMatrix, has been in business since 1991 as a manufacturer of quality software platforms for Amateur Radio applications. Our 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 where you will find the QSL route and manager information for over 92,000 DX stations. Also offered is our CallMaster database containing the complete US and VE Callbooks together with most of the DX callbooks from around the world. Couple these two optional databases  with your Prolog logging system and you have an unbeatable callsign reference library. 

We also offer the LCU-3 computer interface to bi-directionally control your transceiver from the ProLog environment. Our USCNV USB to Serial converter is the perfect solution to the problem of running out of serial ports on your computer. 

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 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 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.

We at DataMatrix understand that product support after the sale is an important part of your purchase decision. DataMatrix is not an "After-Hours" business, it is operated on a full-time basis with comprehensive technical support available from 9 A.M. to 6 P.M. MST, six days a week.
