Audio Carrier Frequency

A video signal has several audio carrier frequencies assigned to it. With
the MSK 24 you can select the main carrier and subcarrier frequencies to
hear them separately. The audio carrier frequency can be set in steps of
10 kHz from 5.0 MHz to 8.99 MHz. The audio carrier bandwidth is
automatically switched over from "wide" (280 kHz) to "narrow" (150 kHz)
at 7.00 MHz

The following factory settings for the audio carrier frequencies are stored
in the receiver when it leaves the factory:
