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:
Button Frequency in MHz Bandwidth in kHz
[1] 5.80 280
[2] 6.50 280
[3] 6.65 280
[4] 7.02 150
[5] 7.20 150
[6] 7.38 150
[7] 7.56 150
[8] 7.74 150
[9] 7.92 150
Overview of commands in Audio Carrier Frequencies (SAT)
[2ndF] [SC] Call up audio carrier menu
[1]...[9] Select audio subcarrier
[-] or [+] Change audio carrier frequency in 10 kHz steps
[ENTER] Manually switch audio carrier bandwidth
wide = 280 kHz, narrow = 150 kHz
Exit audio carrier menu by pressing [2ndF] twice.
Example
Call up audio carrier with 7.38 MHz
Press [2ndF] [SC] [6]
LC display:
• Audio subcarrier: 7.38 MHz
• Audio carrier bandwidth: narrow = 150 kHz
• Mode: SAT
Note
After the SAT mode has been called up, the MSK 24 is always set to the
audio carrier 7.02 MHz. Changes made to the frequency of the audio
carrier are only retained until you exit the SAT mode.
