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 factory-set:

Example

Retrieving sound carrier 7.38 MHz:

Press [2ndF] [SC] [6]

LC display:

• Sound subcarrier: 7.38 MHz
• Sound carrier bandwidth: narrow = 150 kHz
• Mode: SAT

Note

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.
