mmdvmcal.exe \.com18
com18是端口号，每台电脑都不同，比如在设备管理器看到是串口8改为8即可
按b是测试DMR的误码率，默认接收频率433mhz
This is the calibration program to be used with the MMDVM and MMDVM_HS. It is started by
adding the serial port onto the command line. On Windows the serial port must be
prefixed with . as in .COM4 to be valid. Once started the program takes
the following commands:
- MMDVM:
| Command | Description |
|---|---|
| H/h | Display help |
| Q/q | Quit |
| W/w | Enable/disable modem debug messages |
| I | Toggle transmit inversion |
| i | Toggle receive inversion |
| O | Increase TX DC offset level |
| o | Decrease TX DC offset level |
| C | Increase RX DC offset level |
| c | Decrease RX DC offset level |
| P/p | Toggle PTT inversion |
| R | Increase receive level |
| r | Decrease receive level |
| T | Increase transmit level |
| t | Decrease transmit level |
