  • JMSK - JMSK is a software modem that implements a good coherent MSK demodulator that has performance comparable to BPSK. Signals are demodulated from the soundcard. Modulated signals can be routed through the soundcard or to an external device such as a DDS module for direct RF modulation. The advantage of MSK compared to PSK is that non linear amplifiers can be used and has a faster roll off. It is an open source cross-platform program written in C++ Qt.
