T2B-2010: VHF/UHF operating practices; SSB phone, FM repeater, simplex, frequency offsets, splits and shifts, CTCSS, DTMF, tone squelch, carrier squelch, phonetics
T2B01:
What is the term used to describe an amateur station that is transmitting and receiving on the same frequency?
Simplex communication
Full duplex communication
Diplex communication
Half duplex communication
T2B02:
What is the term used to describe the use of a sub-audible tone transmitted with normal voice audio to open the squelch of a receiver?
CTCSS
Carrier squelch
Tone burst
DTMF
T2B03:
Which of the following describes the muting of receiver audio controlled solely by the presence or absence of an RF signal?
Carrier squelch
Tone squelch
CTCSS
Modulated carrier
T2B04:
Which of the following common problems might cause you to be able to hear but not access a repeater even when transmitting with the proper offset?
All of these choices are correct
The repeater receiver requires audio tone burst for access
The repeater receiver requires a CTCSS tone for access
The repeater receiver may require a DCS tone sequence for access
T2B05:
What determines the amount of deviation of an FM signal?
The amplitude of the modulating signal
Both the frequency and amplitude of the modulating signal
The frequency of the modulating signal
The relative phase of the modulating signal and the carrier
T2B06:
What happens when the deviation of an FM transmitter is increased?
Its signal occupies more bandwidth
Its output power increases
Its output power and bandwidth increases
Asymmetric modulation occurs
T2B07:
What should you do if you receive a report that your station’s transmissions are causing splatter or interference on nearby frequencies?
Check your transmitter for off-frequency operation or spurious emissions
Increase transmit power
Change mode of transmission
Report the interference to the equipment manufacturer
T2B08:
What is the proper course of action if your station’s transmission unintentionally interferes with another station?
Properly identify your transmission and move to a different frequency
Rotate your antenna slightly
Increase power
Change antenna polarization
T2B09:
Which of the following methods is encouraged by the FCC when identifying your station when using phone?
Use of a phonetic alphabet
Send your call sign in CW as well as voice
Repeat your call sign three times
Increase your signal to full power when identifying
T2B10:
What is the "Q" signal used to indicate that you are receiving interference from other stations?
QRM
QRN
QTH
QSB
T2B11:
What is the "Q" signal used to indicate that you are changing frequency?
QSY
QRU
QSL
QRZ
