I just listened to it. First of all, the video said "QRM?". These DSP units reduce QRN/background noise floor, *not* interfering stations (QRM). I noticed that when the unit was switched in, the station's audio volume dropped, and some slight "watery" artifacts were introduced. But it did reduce background noise considerably, making it more comfortable to listen to. The West Mountain Radio CLRdsp unit similarly reduces the noise, but the signal's audio remains at constant volume even with advancing the filter level control, with no watery artifacts.
