Station setup: Flashcards
Why should wiring between the power source and radio be heavy-gauge wire and kept as short as possible?
To avoid voltage falling below that needed for proper operation
What must be considered to determine the minimum current capacity needed for a transceiver power supply?
All of these choices are correct
(Efficiency of the transmitter at full power output
Receiver and control circuit power
Power supply regulation and heat dissipation)
How might a computer be used as part of an amateur radio station?
All of these choices are correct
(For logging contacts and contact information
For sending and/or receiving CW
For generating and decoding digital signals)
Which of the following connections might be used between a voice transceiver and a computer for digital operation?
Receive audio, transmit audio, and push-to-talk (PTT)
Which computer sound card port is connected to a transceiver’s headphone or speaker output for operating digital modes?
Microphone or line input
How is a computer’s sound card used when conducting digital communications?
The sound card provides audio to the microphone input and converts received audio to digital form
Which of the following could you use to cure distorted audio caused by RF current on the shield of a microphone cable?
Ferrite choke
Which of the following conductors provides the lowest impedance to RF signals?
Flat strap
Where should the negative return connection of a mobile transceiver’s power cable be connected?
At the battery or engine block ground strap
What is the source of a high-pitched whine that varies with the engine speed in a mobile transceiver’s receive audio?
The alternator
Which of the following could be used to remove power line noise or ignition noise?
Noise blanker
Which of the following would reduce ignition interference to a receiver?
Turn on the noise blanker
