程序中50行以前的这些内容是主要配置，具体含义可以用翻译软件翻译，我这里就不一一描述了。
重点配置的几条我会标记出来。
//两个斜杠的意思是注释，如果有这个斜杠就是功能失效，去掉斜杠就是打开这个功能。

#define SEMI_QSK 1 // Just after keying the transmitter, keeps the RX muted for a short amount of time in the anticipation for continued keying
#define RIT_ENABLE 1 // Receive-In-Transit alternates the receiving frequency with an user-defined offset to compensate for any necessary tuning needed on receive
