Trial of receiving DRM broadcasting in Japan (failure)
DRM (Digital Radio Mondiale) is a digital version of AM broadcasting used in medium and short waves. At present, there is no DRM broadcast in Japan, so I tried to receive a Chinese DRM broadcast (6.030 MHz). The equipment used was a software defined radio KiwiSDR and a whip antenna.
The IQ (in-phase, quadrature) signal captured by KiwiSDR is converted into a WAV file, and the file is supplied to Dream AM/DRM Receiver for demodulation.
If the conditions are good, I can see Time Sync Acq. and Frame Sync., but it doesn’t go well. I will challenge in the future.
