jLog v6.8.0.3 released

About jLog

jLog is a free Java based Ham Logging program that can run on all major platforms, e.g. Mac OS X, Linux/Unix, Windows, etc. It offers a nice, clean interface and allows efficient entry of QSOs.

Import or Export of data using the standardized ADIF 3 or ADIF 2 formats are possible to easily exchange data with any other Log programs.

jLog is written in Java and needs a Java Runtime Environment (JRE) to run both the installer and the application. JREs are available for all major platforms, either as an integrated part or as an installable option.
