T5C: Repeaters; repeater and simplex operating techniques, offsets, selective squelch, open and closed repeaters, linked repeaters
T5C01:
What is one purpose of a repeater?
To extend the usable range of mobile and low-power stations
To cut your power bill by using someone else's higher power system
To transmit signals for observing propagation and reception
To communicate with stations in services other than amateur
T5C02:
What is a courtesy tone?
A tone used to indicate when a transmission is complete
A tone used to identify the repeater
A tone used to indicate that a message is waiting for someone
A tone used to activate a receiver in case of severe weather
T5C03:
Which of the following is the most important information to know before using a repeater?
The repeater input and output frequencies
The repeater call sign
The repeater power level
Whether or not the repeater has an autopatch
T5C04:
Why should you pause briefly between transmissions when using a repeater?
To listen for anyone wanting to break in
To let your radio cool off
To reach for pencil and paper so you can take notes
To dial up the repeater's autopatch
T5C05:
What is the most common input/output frequency offset for repeaters in the 2-meter band?
0.6 MHz
1.0 MHz
1.6 MHz
5.0 MHz
T5C06:
What is the most common input/output frequency offset for repeaters in the 70-centimeter band?
5.0 MHz
600 kHz
1.0 MHz
1.6 MHz
T5C07:
What is meant by the terms input and output frequency when referring to repeater operations?
The repeater receives on one frequency and transmits on another
The repeater offers a choice of operating frequencies
One frequency is used to control the repeater and another is used to retransmit received signals
The repeater must receive an access code on one frequency before it will begin transmitting
T5C08:
What is the meaning of the term simplex operation?
Transmitting and receiving on the same frequency
Transmitting and receiving over a wide area
Transmitting on one frequency and receiving on another
Transmitting one-way communications
T5C09:
What is a reason to use simplex instead of a repeater?
To avoid tying up the repeater when direct contact is possible
When the most reliable communications are needed
When an emergency telephone call is needed
When you are traveling and need some local information
T5C10:
How might you find out if you could communicate with a station using simplex instead of a repeater?
Check the repeater input frequency to see if you can hear the other station
Check to see if you can hear the other station on a different frequency band
Check to see if you can hear a more distant repeater
Check to see if a third station can hear both of you
T5C11:
What is the term for a series of repeaters that can be connected to one another to provide users with a wider coverage?
Linked repeater system
Open repeater system
Closed repeater system
Locked repeater system
T5C12:
What is the main reason repeaters should be approved by the local frequency coordinator before being installed?
Coordination minimizes interference between repeaters and makes the most efficient use of available frequencies
Coordination is required by the FCC
Repeater manufacturers have exclusive territories and you could be fined for using the wrong equipment
Only coordinated systems will be approved by the officers of the local radio club
T5C13:
Which of the following statements regarding use of repeaters is true?
Access to any repeater may be limited by the repeater owner
All amateur radio operators have the right to use any repeater at any time
Closed repeaters must be opened at the request of any amateur wishing to use it
Open repeaters are required to use CTCSS tones for access
T5C14:
What term is used to describe a repeater when use is restricted to the members of a club or group?
A closed repeater
A beacon station
An open repeater
A auxiliary station
