Single Side Band- A method used to reduce the amount of bandwidth a signal occupies. 一种用于削减旌旗灯号占用的带宽量的办法。

S-meter squelch- A pre-set threshold that tells you how strong the message is. When receiving levels stronger than the pre-set level a mute function kicks in and blocks annoying signals. 一个预先设定的阈值，奉告您信息的强度。当接管到的电平高于预设电日常平凡，静音功效会启动并阻止烦人的旌旗灯号。
