ssdv2sat-windows

Windows-friendly fork of ssdv2sat with batch scripts and minor compatibility fixes for transmitting and receiving SSDV images via FM radio.

Requirements

• Python 3.x (from https://python.org)
  • Make sure to check "Add Python to PATH"
• Dire Wolf
• sox
• ssdv.exe

Notes:

• sox.exe must be located inside the sox-14-4-2 folder (as referenced in config.ini)
• ssdv.exe must be placed in the project root directory

Python Setup (Required)

Python 3.8 or newer

Works with Python 3.9 / 3.10 / 3.11

• https://www.python.org/downloads/windows/
• Click “Download Python 3.x

When the installer opens:

• Check this box:
• Add Python to PATH
• Then click:
• Install Now
• This step is mandatory for your .bat files to work.
• To verify, open Command Prompt (type cmd on windows search) and type:
• python --version
• You should see something like:
• Python 3.11.x (or any version that you download)

Required Python packages

• pip install pillow

How to Use (TX)

1. Prepare the image that you want to be sent via SSDV
2. Drag an image onto transmit.bat
3. Enter your callsign
4. Transmission starts automatically

How to Use (RX)

1. Double-click run_rx.bat
2. Dire Wolf starts automatically (if not already running)
3. RX begins

Notes

• These scripts are tested on Windows 10/11
• This repository contains small, Windows-specific modifications to the original tx.py to improve compatibility (mainly sox.exe invocation and path handling)
