Minimum Requirements



  • ARM or x64 distribution
  • 2GB RAM
  • Specifically targeted for the Raspberry PI & Ubuntu

The primary use case for Linux is to have a Raspberry Pi or an x64 distribution running 24/7 with one or more radios connected via USB-to-Serial adapters. The Linux server runs the web front-end and the radio control server. This allows for a remote, standalone server that can run 24/7. It is assumed that the main application and SQL Server run on a bona fide Windows machine or in a VM. Wine will not work.


Quick Install - Windows

  • Apply all Windows Updates
  • Make a backup of the database and the QSL cards, sound clips, etc. in the home folder under W4RLS or N3OEA (the author's previous call sign)
  • If upgrading from SWLog v7 or earlier, delete those files
  • If running SQL Server Express is 2016 or earlier, it will need to be upgraded separately**
  • Run the installation package and install all the checked items. Follow any prompts by the various programs.
** If a previous version of SQL Server is installed, downloading SQL Server 2019 Express directly from Microsoft and performing a manual upgrade is the best option. An alternative method would be, assuming a valid backup exists for not just SWLog but all other databases, to completely remove the old version of SQL Server and let the intallation pacakge install SQL Server 2019 Express.
