T2B-2010: VHF/UHF operating practices; SSB phone, FM repeater, simplex, frequency offsets, splits and shifts, CTCSS, DTMF, tone squelch, carrier squelch, phonetics
What is the term used to describe an amateur station that is transmitting and receiving on the same frequency?
Full duplex communication
Half duplex communication
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?
Which of the following describes the muting of receiver audio controlled solely by the presence or absence of an RF signal?
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
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
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
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
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
Change antenna polarization
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
What is the "Q" signal used to indicate that you are receiving interference from other stations?
What is the "Q" signal used to indicate that you are changing frequency?
