Audio
NNR settings –
Mask floor = the most the network may attenuate noise (e.g. −25 dB). Lower = stronger noise reduction.
SNB settings off
Removes impulse noise (clicks, crackle, ignition) before NNR; adds 28 ms of delay. Higher k1 / k2 = fewer detections (less damage to clean speech). K toggles it.

Advanced
Selecting CW opens the zoom view at its narrowest span (6 kHz) around the dial; leaving CW restores the zoom you had. A zoom change you make yourself in CW is never undone.
