In DSB-SC , we can select which SSB band to demodulate from both received (LSB, USB), in DSB-SC both side bands has the same modulated signal.
> In DSB-SC , we can select to demodulate any of both SSB bands (LSB, USB). In DSB-SC mod type , both side bands has exactly the same modulated content, but sometimes we may have more particular interference signals in one side than the other.
* **F:** The RX frequency can be set in the usual way with text pad when selected
