SDR++: Open Source Software Defined Radio Application

SDR++ is an open source software defined radio application for receiving and transmitting radio signals using software on a computer. It supports many common hardware SDRs and allows tuning, demodulating, and decoding signals over a wide frequency range.

What is SDR++?

SDR++ is an open source, cross-platform software defined radio application capable of receiving and transmitting radio signals using software defined radio hardware connected to a personal computer.

Some of the key features of SDR++ include:

  • Supports many common software defined radios like the RTL-SDR, Airspy, HackRF, and SDRplay
  • Intuitive graphical user interface for tuning, filtering, demodulating, and decoding signals
  • Wide frequency range from 500kHz up to 2GHz depending on hardware capabilities
  • Advanced signal analysis tools like waterfall displays, FFTs, constellation diagrams, etc.
  • Supports common modulation types like AM, FM, SSB, BPSK, QPSK, etc.
  • Can record and replay IQ signal samples for later analysis
  • Built-in automatic mode identification helps detect types of transmissions
  • Scripting capabilities allow automation and customization
  • Free and open source software under GPLv3 license

With its support for affordable SDR hardware and advanced signal analysis capabilities, SDR++ is popular in the radio hobbyist community for exploring and experimenting with radio signals. Its wide frequency range makes it useful for everything from listening to shortwave and ham bands to decoding digital voice transmissions.
