SAT measurement
SAT Analogue Sound Carrier Frequency
Each video signal has several sound carrier frequencies assigned to it. Selective hearing of the sound maincarriers and the sound subcarriers is possible. The sound carrier frequency is tunable from 5.0 MHz to 8.99 MHz in 10 kHz steps. The soundcarrier bandwidth is automatically changed over from wide (280 kHz) to narrow (150 kHz) at 7.00 MHz.
The following sound carrier frequencies are
key | Frequency in MHz | Bandwidth in kHz | |
[1] | 5.80 | 280 | wide |
[2] | 6.50 | 280 | wide |
[3] | 6.65 | 280 | wide |
[4] | 7.02 | 150 | narrow |
[5] | 7.20 | 150 | narrow |
[6] | 7.38 | 150 | narrow |
[7] | 7.56 | 150 | narrow |
[8] | 7.74 | 150 | narrow |
[9] | 7.92 | 150 | narrow |

•Sound subcarrier: 7.38 MHz
•Sound carrier bandwidth: narrow = 150 kHz
•Mode: SAT
After SAT mode has been called up, the MSK 25 will be permanently ☞ adjusted to sound carrier 7.02 MHz. Frequency variations of the sound
carrier will not be retained after SAT mode has been closed.
