*  This example shows how data can be sent from the satellite to the groundstation.
*  The same functions work the other way around as well, and can be used to send data to the satellite from the groundstation.
*  Caution - You should always have an antenna in a radio system before transmitting anything. Make sure the antenna is plugged in before sending data via the radio.
