T1B-2010: Authorized frequencies; frequency allocations, ITU regions, emission type, restricted sub-bands, spectrum sharing, transmissions near band edges
What is the ITU?
A United Nations agency for information and communication technology issues
An agency of the United States Department of Telecommunications Management
An independent frequency coordination agency
A department of the FCC
North American amateur stations are located in which ITU region?
Which frequency is within the 6 meter band?
Which amateur band are you using when your station is transmitting on 146.52 MHz?
2 meter band
20 meter band
14 meter band
6 meter band
Which 70 cm frequency is authorized to a Technician Class license holder operating in ITU Region 2?
Which 23 cm frequency is authorized to a Technician Class operator license?
What amateur band are you using if you are transmitting on 223.50 MHz?
1.25 meter band
15 meter band
10 meter band
2 meter band
What do the FCC rules mean when an amateur frequency band is said to be available on a secondary basis?
Amateurs may not cause harmful interference to primary users
Secondary users of a frequency have equal rights to operate
Amateurs are only allowed to use the frequency at night
Secondary users are not allowed on amateur bands
Why should you not set your transmit frequency to be exactly at the edge of an amateur band or sub-band?
All of these choices are correct
To allow for calibration error in the transmitter frequency display
So that modulation sidebands do not extend beyond the band edge
To allow for transmitter frequency drift
Which of the bands available to Technician Class operators have mode-restricted sub-bands?
The 6 meter, 2 meter, and 1.25 meter bands
The 6 meter, 2 meter, and 70 cm bands
The 2 meter and 13 cm bands
The 2 meter and 70 cm bands
What emission modes are permitted in the mode-restricted sub-bands at 50.0 to 50.1 MHz and 144.0 to 144.1 MHz?
