Windows build
Download the Windows ZIP, extract it, then run the executable. If Windows warns about an unsigned app, choose the manual allow option only if you trust the file.
Help
Downloads Help
Use the downloads page to get builds, web files, CSV files and microcontroller resources.
Mac builds
Download the correct Mac package for Intel or Apple Silicon, extract it, then use right-click Open on first launch if macOS blocks it.
Browser upload
Upload the files so index.html is directly inside public_html or htdocs. A nested folder can cause the wrong URL or a 403 error.
CSV files
Use CSV files for frequency library import, editing and backup. Keep a saved copy before making large changes.
ESP32 sketches
Sketches are starting points for boards. Check pins, screen type, libraries and power wiring before flashing.
Updating
Replace the old files with the new files, then clear browser cache if the old layout still appears.
