DW 15205KHz DRM using DREAM on Mac OS X

http://tiny.cc/rskdux Save 70% on any soft at M4gear
This is a DRM reception of DW 15205KHz broadcast from Srilanka beam to far east (Singapore). I used Elektor SDR 052007. Since it doesn't work on Mac OS X, used another windows laptop to tune into and feed the IQ into MacBooks' line-in. The audio quality is better than HP 6000 laptop. Antenna i used 70cm round loop, on turn of normal electric wire. Antenna connected to preamplifier published Elektor 012000 (Wideband active loop antenna for general coverage receivers). I tried DREAM for AM stations, but the demodulation doesn't worked as it should. Any comments welcome. thanks for viewing.
