KLog Windows package update

After some reports of problems with the windows package of KLog, I have just updated the installer.

The problem was caused because the previous installer was including a wrong version of the SQLite Qt library.

It is fixed now.

If you had some problems with the Windows version, please uninstall KLog completely and install with the new installer that is in the download page.

I hope you enjoy KLog!

KLog – Minor bugfix release

I have just released fixing a bug preventing the frequencies shown being higher than 99.999 MHz.

As it was easy to fix and it could affect VHF and higher freqs users (satellite, EME operators…) I decided to release quickly.

KLog 0.9.7 – Managing satellites

KLog 0.9.7 is ready for release.

There is one main new feature and some other minor topics.

From KLog 0.9.7 you will be able to add, remove or edit satellites to the KLog DB and you will also be able to import or export satellites data lists.

The other thing that you will be able to do from now, it is to disable the DX-Marathon support. Some of the KLog users are not DX-Marathon followers and it is very convenient to be able to get rid of the DX-Marathon status, specially in the DX-Cluster!

As always, this is the changelog:

March – 0.9.7

  • Bugfix: When clicking on Check updates, the dialog froze.
  • Bugfix: Printing log is not longer showing band in the mode column.
  • Updated the default date on date boxes to the current date.
  • Improved the Frequency syncronization between Satellite tab and the main tab.
  • Improved how default mode is calculated.
  • Added Satellites widget in Setup.
  • Updated translations: Catalan (TNX Txema), Danish (TNX Joe), Finnish (TNX Kristjan), French (F4HWL), German (TNX Burkhard), Spanish (EA4TV).

You can download KLog from:

KLog will speak French

A new language is coming to KLog!

Now it is time for French, that will make KLog to be closer to all the hamradio community in France.

Once again, it is one of the KDE translation/localization teams, this time the KDE-fr team, who came to help KLog.

Thank you Christophe!

KLog will speak German soon

KLog is being translated into German by one KDE-de team member and next release (0.9.5) will probably be fully translated into German!

Translators are bringing KLog to new users.

Thank you Burkhard for your help!

KLog – Bugfix quick release

Murphy has came to KLog 0.9.4 and just after releasing, I found a bug.

Not too important, no data was lost and everything worked OK but the message that was shown to the user when a QSO was coming from WSJT-X was incorrect as the operator callsign was not properly parsed from the WSJT-X data.

Being a release that is mainly focused to WSJT-X… I decided to fix it ASAP.

Anyway, I have just released with that bugfix only.

As always, you can download from the repositories.

Enjoy KLog and report any bug you may find!
