Audio Sample
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.


Frequencies[edit]

One of the primary frequencies for this mode is 14236 khz, in the 20 meter ham band.
