I've been using WindTerm for a while and noticed there aren't many ready-made themes out there, so I made and put together a small collection and published it on GitHub.

It includes a handful of color schemes that you can drop directly into your WindTerm themes folder, no extra steps.

If anyone has a palette they like and wants to contribute, PRs are welcome. Happy to hear feedback too.

Hey r/RTLSDR! I've been working on a CLI-first spectrum analyzer and wanted to share it with the community. It's designed to be lightweight and scriptable for automated monitoring.

What it does:

  • Real-time spectrum + waterfall (GUI or headless over SSH)
  • Automatic signal detection with adaptive noise floor
  • Frequency sweeping across ranges with CSV/SQLite export
  • IQ recording (.raw for GNU Radio, .npz for NumPy)
  • SQLite storage with terminal stats dashboard

Example usage:

# Basic monitoring
rtl-sdr-analyzer analyze --freq 446e6 --headless

# Sweep 400-500 MHz
rtl-sdr-analyzer sweep 400e6 500e6 --step 1e6 --db-path scan.db

# View stats
rtl-sdr-analyzer stats scan.db

Tech stack: Python, Typer, Pydantic, matplotlib, SQLite + Rich

GitHub (MIT, open to contributions): https://github.com/msalexms/rtl-sdr-analyzer

Right now it works over RTL-TCP (tested with the rtl-sdr Docker container). Feedback and contributions are very welcome — what would make this more useful for your setups?
