The config includes the calibration data, so ALWAYS save the config.

Some normal steps before more detailed troubleshooting.

1. Check the power supply voltage while transmitting, the KX3 can display that.
2. Open up the KX3 and reseat the ribbon connectors.
3. Check that all external cables are really, fully seated.
4. After saving a config, EEINIT, then reload config.
5. Update the firmware.
