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
T1D04: What is the only time an amateur station is authorized to transmit music?
When incidental to an authorized retransmission of manned spacecraft communications

When the purpose is to interfere with an illegal transmission
When the music is transmitted above 1280 MHz
T1E08: What type of control is being used for a repeater when the control operator is not present at a control point?
T1F07: Which of the following restrictions apply when appending a self-assigned call sign indicator?

It must be less than five letters
It must start with the letters AA through AL, K, N, or W and be not less than two characters or more than five characters in length
It must not conflict with any other indicator specified by the FCC rules or with any call sign prefix assigned to another country
T2A08: What is the meaning of the procedural signal "CQ"?
Call on the quarter hour
A new antenna is being tested (no station should answer)
Only the called station should transmit
Calling any station
T2B10: What is the "Q" signal used to indicate that you are receiving interference from other stations?
