I wrote this logger for convenient work with TNXQSO.com

The program sends the current QSO to the Log tab of your station's pages on the TNXQSO.com. Clicking on the arrow near the frequency sends your frequency to your station’s chat and to the Status tab.
The program sends the coordinates to the server. These coordinates are used to mark your location on the map in the Map tab.
Built-in chat from TNXQSO. If you specify the login/password for the server, you can communicate in a personal chat station.
Log statistics are kept with the division by bands and modes.
If you click on the callsign in the Log section, a window appears for editing or deleting the QSO.
The log can be exported to standard ADIF and saved in the phone’s memory.
https://play.google.com/store/apps/details?id=com.tnxqso.tnxlogTNXQSO.com is the website for the information support of amateur radio expeditions (or just radiotrips).
Now the site is mainly used by Russian amateur radio enthusiasts who activate various regions of Russia for the RDA (Russian Districts Award) diploma program. But then we thought that the site could also be interesting to other hams in the world.
Using the site’s services for all is free.
