DRM30

Decodes DRM (Digital Radio Mondiale) signals coming in through the external microphone input.
(We need to supply DRM signal to microphone input.)

The DRM30 app is for DRM30 decoding with HE-AAC. The free DRM30 app decodes sound and metadata only.

The DRM30 app requires a RC high pass filter audio line as well as a RF front-end module with antenna, tuner, modulator, IF mixer, AF amplifier.

If the Siri app is started while DRM audio is being decoded, or the home button is pressed or the screen is locked by pressing the power button on your iPhone, the DRM30 app may stop, in which case you can simply restart the DRM30 app.

If there is no input signal from Radio for more than 5 minutes, the DRM30 app may behave abnormally, in which case pressing the Clear button once will fix the problem.
