Calling any station
 

 6. 

T2A12 Which of the following is a guideline to use when choosing an operating frequency for calling CQ?

c.
Make sure you are in your assigned band
b.
Ask if the frequency is in use
d.
All of these choices are correct
 

 7.

a.
Full duplex communication
c.
Simplex communication
b.
Diplex communication
d.
Multiplex communication
 

 8. 

T2B03 Which of the following describes the muting of receiver audio controlled solely by the presence or absence of an RF signal?
a.
Tone squelch
c.
CTCSS
b.
Carrier squelch
d.
Modulated carrier
 

 9. 

T2B08 Which of the following applies when two stations transmitting on the same frequency interfere with each other?
a.
Common courtesy should prevail, but no one has absolute right to an amateur frequency
c.
Whoever has been on the frequency the longest has priority on the frequency
b.
Whoever has the strongest signal has priority on the frequency
d.
The station which has the weakest signal has priority on the frequency
 

 10. 

T2B10 Which Q signal indicates that you are receiving interference from other stations?

QRM
c.
QTH
b.
QRN
d.
QSB

QRU
c.
QSL
b.
QSY
d.
QRZ
 

 12. 

T2B12 Under what circumstances should you consider communicating via simplex rather than a repeater?
a.
When the stations can communicate directly without using a repeater
c.
Only when third party traffic is not being passed
b.
Only when you have an endorsement for simplex operation on your license
d.
Only if you have simplex modulation capability
 

 13. 

T3A01 What should you do if another operator reports that your station’s 2 meter signals were strong just a moment ago, but now they are weak or distorted?
a.
Change the batteries in your radio to a different type
c.
Ask the other operator to adjust his squelch control
b.
Turn on the CTCSS tone
d.
Try moving a few feet or changing the direction of your antenna if possible, as reflections may be causing multi-path distortion
 

 14. 

T3A02 Why are UHF signals often more effective from inside buildings than VHF signals?
a.
VHF signals lose power faster over distance
c.
This is incorrect; VHF works better than UHF inside buildings
b.
The shorter wavelength allows them to more easily penetrate the structure of buildings
d.
UHF antennas are more efficient than VHF antennas
 

 15. 

T3A05 When using a directional antenna, how might your station be able to access a distant repeater if buildings or obstructions are blocking the direct line of sight path?
a.
Change from vertical to horizontal polarization
c.
Try the long path
b.
Try to find a path that reflects signals to the repeater
d.
Increase the antenna SWR
 

 16.
