The following picture shows the Fraunhofer Software Radio system for reception of DRM signals Commercial PC with Frontend FhG Software Radio DRM Signal in the Air Antenna 12 kHz uuuuuuuuu e o The DRM Signal is received by an commercial long medium shortwave SW MW LW front end Any front end should be usable which can provide an IF of 12 kHz direct or with a adapter circuit The bandwidth must be greater 10 kHz for normal transmissions and greater 20 kHz for transmissions with channel bundling Due to a good performance price relation we offer in our Basic Package B1 the AOR 7030 SW MW LW commercial receiver This receiver requires an external antenna The AOR 7030 is modified for a wider IF bandwidth and is equipped with an additional 455 kHz to 12 kHz converter which is mounted inside the AOR 7030 Output of the AOR 7030 is the DRM female connector at the backside of the unit The signal provided at this connector is the DRM signal at an IF intermediate frequency of 12 kHz This signal is then fed into a standard soundcard The soundcard must offer a sampling rate of 48 kHz For output of the audio signal also a soundcard with a sampling rate of 48 kHz is required If one sound card is used for sampling the signal and output of the music the soundcard must provide full duplex operation Most of all newer soundcards provide all these features e g SoundBlaster Live from Creative Labs Attention must be taken not to us
