1. Under Audio section -- UNcheck "Filter Audio"
2. Set bandwidth to something like 8500
Perhaps my mind is playing tricks with me, but I feel that I get better decodes if I run WFM rather than NFM. But, regardless of which you run, you also want to make sure your audio level is reasonable. You don't want the audio gain to be so high that it clips, and you don't want it to be so low that its not useful to DSD+. Since I run in WFM mode, audio level is automatically much lower. With my volume turned all the way up, it's just enough audio gain with no room to spare. If I run NFM, I have plenty of audio gain and usually have to run SDR# audio at about 75%. Of course this will differ in every situation,
