On  OH2K club meet the idea of doing some HF band Digital Radio Mondiale transmit experiments was raised. 
This lead to some research on the subject.

This page exists to document my research and experiments on the subject. 

One promising commercial DRM modulation software is DRM Sender:

It seems to offer linelevel I/Q output via a normal soundcard, making it very hobbyist friendly. 

Got the trial version of drm-sender, now the next step is experimenting with it and seeing if it can output raw I/Q with the soundcard for feeding into a quadrature modulator. 

More stuff as research and experiments as they get done.
