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!

KLog-0.9.4 – Receive your data from WSJTX automatically

KLog 0.9.4 is finally here and it brings one interesting new feature and one important bugfix.

Now it is possible to send QSO data directly from WSJT-X to KLog and KLog will update it in the QSO entry or log the QSO sent from WSJT-X.
It will really save time for those of us using WSJT-X!

In addition the translations for Catalan, Croatian, Danish, Spanish and of course English, have been fully updated.

Find below the Changelog.

August 2018 – 0.9.4

  • WSJT-X support to receive logged QSO and realtime data.
  • Check bool DataBase::updateTo012() / it was always returning true without any action.
  • Syncronize RX Freq with the satellite downlink combobox.
  • Focus is back to search line edit when right click on the list of found QSOs.
  • Update process has been improved.
  • Some warnings removed from compilation time.
  • Bugfix: Date was not properly calculated and UTC settings was not applied. That may create wrong date QSO when date changes due to UTC (TNX AC1DW).
  • Bugfix: When adding a QSO, if the QSL is marked as received, KLog showed a SQL error.
  • Bugfix: Table qsl_via needed to be renamed (TNX EA6ZS).
  • Bugfix: Some DXCC status were nor properly calculated.
  • Updated translations: Catalan (TNX Josep), Croatian (TNX M0NKC), Danish (TNX Joe), Spanish (EA4TV).

You can download KLog from:

Please wait some time if the browser returns a file not found error. It may be caused due to the mirrors need to update. The process could take up to 24h!

Thank you to the contributors of this version!

I hope you enjoy KLog!

KLog-0.9.3 – Now with Kosovo and bugfixes

A new release has arrived!

There is just one new feature and Kosovo, that has been added (as it was added by the ARRL to the DXCC list) but there are many bugfixes that improves the quality of KLog.

Test the new feature and doubleclick on the entity name in the DXCC widget, you will see the QSOs that are supporting the DXCC status for that entity. I think it is interesting to follow up your DXCC!

Check the Changelog summary to see the details:

April – 0.9.3

  • Double clicking on DXCC Widget name of the Entity will show the QSO is providing that status on the Search widget.
  • Added DXCC support for Kosovo.
  • Bugfix: Default band & mode are now defined as the most used band and mode.
  • Bugfix: TX frequency was not saved.
  • Bugfix: In the dxcc status widget, some countries were showing the UN flag unappropriately.
  • Bugfix: When updating the CTY file, query errors were shown on world.readCTYCSV function.
  • Bugfix: When editing the QRZ, the cursor position was not properly maintained.
  • Bugfix: Fixed the flags of several DXCC entities that were not correctly shown.
  • Bugfix: DXCC Status widget was not listing all the DX entities.
  • Bugfix: Modes & Bands where not always properly updated from the Setup.
  • Bugfix: Adding new QSO that implies a DXCC or WAZ status already worked failed.
  • Bugfix: Updating the WAZ status was not always possible due to a incorrect DB query.
  • Updated translations: Danish (TNX Joe), Spanish (EA4TV).

Enjoy KLog!

KLog Windows update

I have released a new release ONLY for Windows.

Just for those of you that are curious, in the previous package the file containing the libraries to manage the database was missing and it was not possible to connect to the DB.

Again, it is just a Windows installer release and you can find it here:


If you can’t download the file, please give some time to the mirrors to update 🙂
