Why? Aside from not having the 10 Hz shift problem, digital modes are generally used on upper sideband on all bands these days - particularly when audio-sourced modulation schemes are used.

为什么？除了没有在10赫兹的转变问题，数字模式，一般用在上边带在所有这些天-尤其是当音频来源调制方案，使用带。

Using upper sideband also allow the actual carrier frequency to be determined easily simply by adding the dial frequency to the audio modulation frequency.

使用上边带还允许实际载波频率确定仅仅通过增加拨号频率的音频调制频率容易。

In addition, owing to Bi-system superconductors in the structure are more complex, these questions are
