I've got DSD+ running with my RTL-SDR. Not sure if I've got it working right or not. When i switch the radio to NFM as the tutorial says to do, all goes silent. I notice if I put it on WFM that I hear noise. I've been trying to find frequencies to listen to all day long but none of them seem to cause the DSD+ window to start scrolling. Last line in DSD says "Mono audio decoding initiated;" nothing happens after that.
