KLog 1.0 – “First release” arrives after 17 years :-)

It is strange for me to publish KLog 1.0 but I ran out of numbers to keep KLog below version 1.0… and I decided not to keep playing games with versionig so today I am releasing KLog 1.0.

First KLog release was on 22-Jan-2003, the 0.1-pre-alpha, with this very simple Changelog:

22-Jan-2003 - 0.1-pre-alpha

  • First "release" of the software.
  • You can add/edit QSOs and save/read your log to/from the disk with a fixed name in ADIF format.
  • Can manage QSL sent/rec.

KLog has evolved a lot since that very first version… very slowly, but continuously.

But it is not that KLog has evolved a lot since the previous version or has reached a different maturity level… it is simply that I could not continue releasing versions below 1.0, just that simple! O:-)

However in this release there is, at least one interesting thing. It is that you can now upload to LoTW your QSO without having to export the ADIF file and import it again to TQSL.

KLog will send the QSOs to TQSL and will call TQSL for you so the LoTW upload has drastically been improved!

So, just to let you know what’s new in KLog, find below the Changelog

March 2020 – 1.0

  • New feature: Integrate TQSL to upload QSOs to LoTW directly from KLog.
  • UI: Removed the first column inthe DXCC widget to make it more user friendly.
  • UI: Created a widget to manage the Main QSO entry to make KLog more modular.

  • New feature: You can check a call in DXHeat.com by right-clicking in the call from the log.
  • New feature: It is now possible to save in a file all the DX-Cluster activity.
  • Improvement: Added https to the cty.dat download.
  • Improvement: Added the https to download.klog.xyz
  • Improvement: Propagation modes are now sorted in the Propagation mode combobox.
  • Improvement: Four new tips added.
  • Improvement: eQSL & LoTW dates are updated always that are modified to any status.
  • Improvement: If a QSO does not have a freq, a default freq based on the band is assigned if edited.
  • Improvement: Removed some deprecated functions.
  • Improvement: Improved the way KLog checks for a wrong call (IARU rules applied).
  • Improvement: Improved the way KLog checks for a wrong IOTA reference.
  • Removed the functionality to sort the log based on Date & Time columns.
  • Removed one console message about a duplicated database connection.
  • Bugfix: It was not possible to include new dxcluster servers in the setup.
  • Bugfix: The default value of RST in some digital modes using SNR were not properly shown.

KLog 0.9.7.2 Windows package update

After some reports of problems with the windows package of KLog 0.9.7.2, 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 0.9.7.2 Windows version, please uninstall KLog completely and install with the new installer that is in the download page.

I hope you enjoy KLog!

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).
