When using the noise blanker, received signals may be distorted if they are excessively strong or the noise type is other than impulse. Nearby strong signals can also cause the noise blanker to create distortion. Turn the noise blanker function OFF, or adjust the noise blanker level to a shallower setting (see below) in this case.
