GNU Radio is a Free/Libre toolkit that can be used to develop software-defined radios. This framework uses a combination of C++ and Python to optimize DSP performance while providing an easy-to-use application programming environment.GNU Radio Companion is a graphical programming environment provided with GNU Radio.

Waterfall plots are often used to show how two-dimensional phenomena change over time. [1] A three-dimensional spectral waterfall plot is a plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with "nearer" curves masking the ones behind.
Spectrogram (waterfall display) of an Olivia 16/500 signal centered on 7073.25 kHz Olivia MFSK is an amateur radioteletype protocol, using multiple frequency-shift keying (MFSK) and designed to work in difficult (low signal-to-noise ratio plus multipath propagation) conditions on shortwave bands.
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
A waterfall display depicting several PSK31 transmissions at around 14,070 kHz. The green lines indicate a station that is transmitting. PSK31 or "Phase Shift Keying, 31 Baud", also BPSK31 and QPSK31, is a popular computer-sound card-generated radioteletype mode, used primarily by amateur radio operators to conduct real-time keyboard-to-keyboard chat, most often using frequencies in the high ...
So give this list of 20 contest-winning desserts a scroll and get ready to be a champion. Chocolate Sheet Cake. When Ree first made her mother-in-law's cake for her husband Ladd, she accidentally ...
A waterfall display showing FT8 in use on the 40-meter band.. FT8 (short for Franke-Taylor design, 8-FSK modulation) is a frequency shift keying digital mode of radio communication used by amateur radio operators worldwide.
