jLog is a modern Logging program for Hams. It can run on all major platforms, e.g. macOS,
Linux, Windows, etc.
It offers a nice, clean interface and allows efficient entry of QSOs.
It is available for free so you can afford to try it!
You won't get stuck with jLog. Import or Export of data using standardized ADIF 3 formats is possible to easily exchange data with any other decent logging program.
Real-time integration with WSJT-X for logging and color coding entries of interest
QRZ and HamQTH lookups. Real-time logging with eQSL and LoTW.
Keep track of QTHs, rigs, etc. and the TQSL Locations and eQSL Nicknames.
Separate tracking of Paper, eQSL and LoTW QSL status with status reporting
Search a huge log in less than a second.
Automatic Award status and Reports, e.g. "WAS"-type for 28 countries.
Available with selectable light or dark themes. Can be set to change with the system theme.
A Botton Bar at the top with frequently used buttons.
Then the Main Window with the Log overview. Navigate up/down using the Up/Down-keys. Open a selected entry by pushing the Space Bar.
A continuously updated Status Window below, updated as the different rows of the Main Window are selected.
The Previous Field below is also continuously updated and is showing either previous contacts with the same station or the same country (selectable).
The Entry window allows entry of new QSOs and display or modification of existing QSOs. The macOS Look and Feel is shown but the look is very similar on Linux and Windows.
For new QSOs, time, frequency and mode is automatically updated from the radio.
The Profile is where most of the settings or preferences are kept.
Configurations are typically used to reflect alternative QTHs, but can be used to reflect e.g. guest Operators or Rigs (in case multiple rigs can be used for a given frequency or mode). These parameters can be closely linked to the TQSL 'Locations' and 'eQSL 'Nicknames'.
Other settings are typical favourite settings, eQSL and LoTW setting, and DX Clusters or Spots settings.
The WSJT-X Tracker (or just Tracker for short) is a built-in tool that links jLog and WSJT-X to provide extended capabilities. It assists the user in keeping track of confirmed Countries, Prefixes, US States and US Counties by both color coding callsigns in WSJT-X entries and by it own list of potential stations of interest. The logic is similar to the color coding of entries in WSJT-X.
WSJT-X indicates e.g. whether or not a specific country has been worked or not. The WSJT-X Tracker on the other hand, indicates whether or not a specific country has been confirmed or not. Confirmation status can be related to both eQSL and LoTW. It will also take into account whether or not the station of interest is listed as an Authenticity Guaranteed (AG) eQSL user or as a confirmed user of LoTW.
New release jLog V6.13 made available on 13 August 2024
An update that repairs the radio serial port modem signal handling. It also improves the awards
Reports significantly, introduces Tracker 'Wanted Stations', etc.
More in the Release notes.
Prior to jLog V 6.7, a Java Runtime Environment had to be installed before installing jLog. This is no longer necessary.
Although the jLog application is the same for any platform, separate installers are available for each major platform to simplify the installation task. The optional serial port used for CAT control and keyer control may require platform specific drivers.
Please do remember to regularly check for updates. Errors are being fixed and new functionality may be added.
Go to the installer page for your platform,
Very old versions (V 6.6 or older) are only available on the old jLog Website
