About:
CubicSDR is a cross-platform graphical SDR application that interfaces with radio hardware via drivers like SoapySDR. It provides a real-time waterfall display and demodulation capabilities for exploring and analyzing radio signals across the spectrum. This tool enables hobbyists and researchers to visualize and listen to various digital and analog transmission modes.

Key Features:

Real-time spectrum visualization with waterfall display
Support for multiple SDR hardware devices via SoapySDR
Built-in demodulation for AM, FM, LSB, USB, and more
Cross-platform GUI built on wxWidgets

Use Cases:

Exploring local RF spectrum activity and signal identification
Listening to amateur radio, air traffic, or maritime communications
Educational tool for learning about software-defined radio principles

Alternatives:

GQRX – GQRX is a popular SDR receiver for Linux and macOS, often considered lighter weight than CubicSDR.
SDR++ – SDR++ is a modern, modular SDR software that is actively developed and cross-platform.
