The DXLog.net project was started by the late Kresimir (Chris or Krešo) Kovarik, 9A5K, in the
summer of 2011 with the ambitious goal to create the most easy to use and versatile contest
logging software available.
DXLog has a classic, keyboard-centric, look-and-feel and builds on a long standing tradition in
keyboard shortcuts and other user interface elements.
Krešo was a central person in the Balkan ham radio community and a globally renowned and generous
contester, which included multiple participations in WRTC.
He was also a software professional which, among other things, has given DXLog perhaps the most
powerful scripting system and the most advanced, and open, support for complex contest rules of all
contest loggers. In fact, unlike with any other contest logger, all users have access to the full
power and flexibility of the DXLog contest rules engine.
Shortly before Krešo's key went tragically silent in the early spring of 2019, his close friend
and ham radio community benefactor Krassy K1LZ acquired all rights to the software, including the
source code, with the ambition to donate it to the ham radio community.
At this time a small team, led by Paul K1XM, was also formed to maintain and develop the software.
Later in the spring Krešo was posthumously inducted into the CQ Contest Hall of Fame for his
contributions to ham radio contesting. The induction speech by Krassy K1LZ can be viewed by
clicking the picture below.
DXLog is still in a state of constant development. New versions offering new features and defect
corrections are released on a regular basis.
The latest version can always be downloaded from HERE.
