An amateur station located more than 50 kilometers above the Earth's surface is called an amateur space station. Any licensed amateur operator may be the licensee of an amateur space station.
The 6-meter band may NOT be used by Earth stations for satellite communications.
False or deceptive amateur signals or communications may NEVER be transmitted. For example, if an amateur pretends there is an emergency and transmits the word "MAYDAY," he is transmitting a false or deceptive signal.
Except for transmissions from a space station or to control a model craft, an amateur may NEVER transmit unidentified communications. An amateur communication that does not have the required station identification is called an unidentified communications or signal. For example if an amateur transmits to test access to a repeater without giving any station identification, he is transmitting an illegal unidentified transmission.
You may NEVER deliberately interfere with another station's communications. A transmission that disturbs other communications is called harmful interference. For example if an amateur repeatedly transmits on a frequency already occupied by a group of amateurs in a net operation, they are transmitting harmful or malicious interference.
