查询词典 process control

RIT control. The receiver incremental Tuning control is used to fine tune to the received singal . This is used in USB and LSB modes to obtain maximum clarity of reception, and in CW mode to control the pitch of the beat note. The RIT Control can tune the receive frequency about 2.3 KHz. This control will not transmit frequency, or the frequency display, but will change the receive frequency.

RIT control ：收信机微调旋钮是用微调调整使你能收到被认为是标准的信号，在USB和LSB模式使用可以获得最清晰的接收，在CW模式可以控制节拍的音调，这个旋钮能在2.3KHz左右调整接收频率，它不影响发射频率和显示频率，但将改变接收频率。
