About Us

Spectre is a free and open source SDR-agnostic program for recording radio signals and spectrograms. It's geared for hobbyists, citizen scientists, and academics who want to achieve scientifically interesting results at low cost.

Powered by GNU Radio and FFTW, it provides high performance on modest hardware. Applications include:

  • Solar and Jovian radio observations
  • Educational outreach and citizen science
  • Amateur radio experimentation
  • Lightning and atmospheric event detection
  • RFI monitoring

Important

We're now building Spectregrams: a global network of low-cost, narrowband FFT spectrometers for solar radio observations.

Features

  • Simple installation with Docker
  • Wide receiver support (SDRplay, HackRF, RTL-SDR, USRP, RX-888 MK II)
  • Run natively on Linux, including Raspberry Pi
  • Intuitive CLI tool
  • Record spectrograms and I/Q data
  • Short and long-form recordings
  • Compatible with inspectrum, NumPy and Astropy
  • FITS standard compliant.
  • Integration with the e-Callisto network
