Mike, Which one of the Bhi Noise Away Modules are you using? Thanks and 73's

Date: Mon, 21 Dec 2009 20:27:02 -0700 I have been fiddling and messing around with the NR button on PSDR since July, and have never been able to get it to reduce noise at all. I was told that it needed to listen and learn about the signals for a while, so I went to experimenting with making a little change to one of the three settings, letting it sit for a few minutes, change, learn, etc. All I ever got was various levels of distortion. My opinion is it is 100% useless. I was just about convinced that noise reduction was a myth, but friends on the air with non-SDR rigs seemed to have various levels of success - none of them had the total failure that I had. Hmmm - stuff like this is supposed to be just a software issue. Well - I now know that noise reduction IS possible. I know because I bought a Bhi Noise Away module which does audio DSP. And it does work! More like "noise elimination". I'm feeding it with the FlexWire line out, and it is AMAZING. I did have to download the latest manual, clip a resistor because of the audio level, and tweak the input and output level pots. From then on it's just a matter of picking what level of noise reduction.oooopps noise elimination I want and I'm in noise-free nirvana! I'm actually worried that I might wear out the switch popping it in and out of circuit - it is just so fun to listen to the noise just vanish! I didn't notice what the chip they use in there is. But my understanding is it's just doing some math on some digitized audio.no magic or anything proprietary involved. Just some awesome programming I guess. Way to go, Bhi. So - it can be done. Maybe someday PSDR will do it. Until then this is the best $180 accessory I have found. The audio examples on their web site sound too good to be true, you'd swear they are faked or fudged some way or another. They aren't.
