Operating Controls Flashcards
What may happen if a transmitter is operated with the microphone gain set too high?
The output signal might become distorted
Which of the following can be used to enter the operating frequency on a modern transceiver?
The keypad or VFO knob
What is a way to enable quick access to a favorite frequency on your transceiver?
Store the frequency in a memory channel
Which of the following is a use for the scanning function of an FM transceiver?
To scan through a range of frequencies to check for activity
What is the purpose of the squelch control on a transceiver?
To mute receiver output noise when no signal is being received
Which is meant by “repeater offset”?
The difference between the repeater’s transmit frequency and its receive frequency
What does the term “RIT” mean?
Receiver Incremental Tuning
Which of the following controls could be used if the voice pitch of a single-sideband signal seems too high or low?
The receiver RIT or clarifier
What is the function of automatic gain control, or AGC?
To keep received audio relatively constant
What is the advantage of having multiple receive bandwidth choices on a multimode transceiver?
Permits noise or interference reduction by selecting a bandwidth matching the mode
