4.1.操作指南
4.1. Operation Guide
固件支持根据RSSI强度，解算最近5秒内的，码率12~30WPM范围内的CW信号
The FW supports decoding CW signals in the last 5 seconds with rate in 12~30WPM based on RSSI record
由于只能得到整个接收带宽内的RSSI强度值，因此推荐使用最小带宽（6.25k）进行CW接收
Since we can only get RSSI value within the entire Rx BW, it is recommended to use the minimum bandwidth (6.25k) for CW decode
CW解码在应用启动后自动进行，仅需通过
CW decoding is running automatically, press
解码器将分析高于检测阈值的RSSI记录，并计算记录时间内的信号码率，然后进行解码
The decoder will analyze RSSI records above the detect threshold and calculate WPM during the recording time and then decode
解码结果将以滚动形式显示在屏幕底部
The decoded results will be displayed in scrolling form at the bottom of the screen
4.2.注意事项
4.2. Attention
RSSI曲线有显示范围，可以根据频率指示下方的实时RSSI找到大致数值
The RSSI curve has display range, you can find the approximate value based on the real-time RSSI below the frequency indicator.
将检测线横穿CW对应的RSSI脉冲曲线以获得更好效果
Place the detection line across the RSSI Pulse for better results
固件根据记录中最长的一条有效信号判断码率，发报方手法不佳可能会造成解码错误
The FW calculate the WPM based on the
