2- Check all SDI-12 connections, including DATA and GND.
3- Check the pin out of the SDI-12 sensor for correct wiring.
4- Make sure all sensors have a unique address.
GOES Transmissions
GOES not transmitting:
1- Check power to the GOES Radio, do so under a load (e.g. a transmission).
2- See if the GOES time is correct, if it is stopped, it indicates power to the radio was lost,
stopping the clock. The radio will not transmit if the GOES clock is not running.
3- Check all antenna wires.
4- Check antenna alignment.
5- Use a power meter to measure the power output of the radio and the reflected power.
