T1B-2014: Authorized frequencies: frequency allocations; ITU regions; emission modes; 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
Why are the frequency assignments for some U.S. Territories different from those in the 50 U.S. States?
Some U. S. Territories are located in ITU regions other than region 2
Territorial governments are allowed to select their own frequency allocations
Territorial frequency allocations must also include those of adjacent countries
Any territory that was in existence before the ratification of the Communications Act of 1934 is exempt from FCC frequency regulations
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 licensee?
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
Which of the following is a result of the fact that the amateur service is secondary in some portions of the 70 cm band?
U.S. amateurs may find non-amateur stations in the bands, and must avoid interfering with them
U.S. amateurs must give foreign amateur stations priority in those portions
International communications are not permitted on 70 cm
Digital transmissions are not permitted on 70 cm
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 above 30 MHz that are 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?
CW and RTTY
CW and SSB
Why are frequency assignments for U.S. stations operating maritime mobile not the same everywhere in the world?
Amateur frequency assignments can vary among the three ITU regions
Amateur maritime mobile stations in international waters must conform to the frequency assignments of the country nearest to their vessel
Frequency assignments are determined by the captain of the vessel
Amateur frequency assignments are different in each of the 90 ITU zones
Which emission may be used between 219 and 220 MHz?
