Lightweight WSPR analytics: DuckDB ingest + Streamlit dashboard.

📡 wspr-ai-lite

Lightweight WSPR analytics with DuckDB + Streamlit

Repository Workflow Staus

Python Package Publishing

Explore Weak Signal Propagation Reporter (WSPR) data with an easy, local dashboard:

• 📊 SNR distributions & monthly spot trends
• 👂 Top reporters, most-heard TX stations
• 🌍 Geographic spread & distance/DX analysis
• 🔄 QSO-like reciprocal reports
• ⏱ Hourly activity heatmaps & yearly unique counts
• 🚀 Works on Windows, Linux, macOS — no heavy server required.

---

✨ Features

• Local DuckDB storage with efficient ingest + caching
• Streamlit UI for interactive exploration
• Distance/DX analysis with Maidenhead grid conversion
• QSO-like reciprocal finder with configurable time window
• Ready-to-run on modest hardware

🚀 Quickstart

1. Clone & Setup

git clone [e-mail]:KI7MT/wspr-ai-lite.git
cd wspr-ai-lite

# optional venv
python3 -m venv .venv && source .venv/bin/activate

pip install -r requirements.txt

2. Ingest Data

Fetch WSPRNet monthly archives and load them into DuckDB:

# adjust to whatever range you wish, but be reasonable !!
python pipelines/ingest.py --from 2014-07 --to 2014-07

• Downloads compressed monthly CSVs (caches locally)
• Normalizes into data/wspr.duckdb
• Adds extra fields (band, reporter grid, tx grid)

3. Run the UI

streamlit run app/wspr_app.py

Then open http://localhost:8501 in your browser.

🛠 Development

For contributors and developers:

• docs/DEV_SETUP.md --> Development setup guide
• docs/TESTING.md --> Testing instructions (pytest + Makefile)
• docs/TROUBLESHOOTING.md --> Common issues & fixes

make setup-dev   # create venv and install deps
make ingest      # run ingest pipeline
make run         # launch Streamlit UI
make test        # run pytest suite

Testing

Run unit tests for ingest and utilities:

pytest -q

Or via Makefile:

make test
