Ultrasonic Noise bar graph - Indicates the MPX signal amplitude in the approximate bandwidth

of 80 kHz – 150 kHz.

Stereo Blend bar graph - In stereo signals, the difference (L-R) component of the MPX signal

is more susceptible to disturbances than the sum (L+R) signal. Therefore, the separation of the left

and right audio channels can be decreased in order the audibility of the disturbance to be reduced.

This channel separation reduction is called "stereo blending". A value of 100% indicates that no

reduction is applied. The level of stereo blending depends on the following input signals: RF

Signal Level, Multipath, Ultrasonic Noise and Pilot tone deviation.
