IOS App Noise Reduction

w9kjo Member ✭✭

I cannot seem to find a plane on the ISO app to adjust the noise reduction. I can turn it on and off but cannot adjust its level.

Where would I find this adjustment?

    Touch the flag that shows the frequency. a tuning tab should popup. Touch the the up arrow on the left top of the tab. that will bring up several control buttons. Touch the DSP button. That will bring up the NR control plus others.

    first you need to Touch Freq Flag to bring up the tuner slider which when expanded shows more info

    Then touch DSP to bring up DSP adjust panel

    that simple to navigate to slider to adjust different DSP fucntions
