Multitasking data analyzer demodulator and decoder for Windows.
Professional software for real-time analysing, demodulation/decoding digital radio-transmission``Demodulation based on the best of the noiseproof correlation algorithms``Demodulation ASK, Morse, FSK, MFSK, CPFSK, GMFSK, FSK4, FSK8, PSK, BPSK, QPSK, FAX
Multiplatoform freeware DSP software. Linrad has its origin in software that was developed for 144 MHz EME CW but it is quite general and should be seen more like a kit for designing a receiver that a receiver for some particular usage. It can be used as a CW receiver with a small time delay and a fast waterfall graph. A dsp for conventional receiver to imporve signals readability, a spectrum analyzer.
