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:
| 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 |
