WinDRM is an amateur radio derivation of the Digital Radio Mondiale (DRM) digital voice and data transmission protocol. Known as HamDRM, and Digital SSTV. Uses the same technology from commercial DRM broadcasts, with COFDMCoded Orthogonal Frequency-Division Multiplexing-QAMQuadrature Amplitude Modulation modulation, and is able to send text, voice, and images. This format was first adopted for amateur use by Francesco Lanza HB9TLK in his own version of Dream, an open-source DRM decoder. This technology was later adopted into WinDRM.
