Requirements & preparation

• A built Windows application. Running the source requires a separate Python environment.
• A receiver that outputs the signal near 17.2 kHz and an audio input that actually passes it.
• 48 kHz recording input, plus speakers or headphones for monitoring.
• A writable folder for settings, recordings and decoded text.

First launch

1. Download the release ZIP and extract all files to a writable folder.
2. Run PSSAQ.exe. The source ZIP and Windows release ZIP are different packages.
3. The initial language is Japanese. Select English or Русский from Language; no restart is required.
4. Follow the setup guide to configure Audio IN / OUT and check reception.

Updating

In supported versions, choose the Windows release ZIP under Help → Update (select ZIP). Keep your settings, recordings and decoded-text folders. The source ZIP is not an update package.
