DSP filters still not working properly. Moving the slider on the ANF does nothing on my radio. The NR does not provide any relief for noise, actually it distorts the audio

    I noticed some distortion, also. Well, with the TNF, I can get around that, for now. I love this radio. Again! (With each upgrade)

    Sri to bump an oldish thread.

    I have a VERY noisy environment and will get around to doing what I can. 2 of the three DSP receive filters do absolutely nothing. The only one that has any effect is the NR filter. Please add me to the list of those wanting these working.

    I'm betting that Flex will get them working. Certainly been enough posts about it. I bet it has their attention. I have found in the meantime that instead of using the ANF to knock out tuner uppers, that just right clicking on the offending signal and selecting Add Tracking Notch Filter, kills it quite effectively. And that's at the default depth! I am lucky that I don't really need the Noise Reduction and Noise Blanker. I live in a rural area and have a very low noise floor. And once I got rid of my Astron power supply, I also got rid of a LOT of birides as well. For Noise Reduction, I just drop the RF Gain down and that cleans up things fairly well.
