T1C05: What must you do if you are operating on the 23 cm band and learn that you are interfering with a radiolocation station outside the United States?
Stop operating or take steps to eliminate the harmful interference
Nothing, because this band is allocated exclusively to the amateur service
Establish contact with the radiolocation station and ask them to change frequency
Change to CW mode, because this would not likely cause interference
T1D07: When is an amateur station authorized to automatically retransmit the radio signals of other amateur stations?

When the signals are from a beacon, repeater, or space station
When the signals are from an Earth, repeater, or space station
T1E01: When must an amateur station have a control operator?
Only when the station is transmitting
