WaveShark

Shortwave and medium wave

DRM

The services in a DRM multiplex, their languages and their labels, off a shortwave or medium wave transmission.

DRM is digital broadcasting in the bands that reach across continents, which is why it is still used by international broadcasters where nothing else carries. A multiplex holds one to four services, each with a language and a label.

What is read here is the multiplex structure rather than the audio: which services exist, in which languages, and how the transmission is configured.

What comes out

  • Services in the multiplex, with labels and languages
  • Robustness mode and spectrum occupancy
  • Service identifiers
