Sat measurement
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 |

[2ndF] [SC] Call up audio carrier menu
[1]...[9] Select audio subcarrier
[ENTER] Manually switch audio carrier bandwidth
wide = 280 kHz, narrow = 150 kHz
Exit audio carrier menu by pressing [2ndF] twice.
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
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.
