2.1 VHF/UHF Repeaters - Voice
What is a good way to make contact on a repeater?
Say the other operator's name, then your call sign three times
Say the call sign of the station you want to contact, then your call sign
Say, "Breaker, breaker,"
Say the call sign of the station you want to contact three times
What is the main purpose of a repeater?
To link amateur stations with the telephone system
To increase the range of portable and mobile stations
To retransmit weather information during severe storm warnings
To make local information available 24 hours a day
What is an autopatch?
A device which connects a mobile station to the next repeater if it moves out of range of the first
A device that allows repeater users to make telephone calls from their stations
A device which locks other stations out of a repeater when there is an important conversation in progress
Something that automatically selects the strongest signal to be repeated
What is the purpose of a repeater time-out timer?
It lets a repeater have a rest period after heavy use
It logs repeater transmit time to predict when a repeater will fail
It tells how long someone has been using a repeater
It limits the amount of time someone can transmit on a repeater
What is a CTCSS (or PL) tone?
A tone used by repeaters to mark the end of a transmission
A sub-audible tone added to a carrier which may cause a receiver to accept a signal
A special signal used for telemetry between amateur space stations and Earth stations
A special signal used for telecommand control of model craft
How do you call another station on a repeater if you know the station's call sign?
Say the station's call sign, then identify your own station
Say "break, break 79," then say the station's call sign
Say "CQ" three times, then say the station's call sign
Wait for the station to call "CQ", then answer it
Why should you pause briefly between transmissions when using a repeater?
To check the SWR of the repeater
To reach for pencil and paper for third-party communications
To dial up the repeater's autopatch
To listen for anyone else wanting to use the repeater
Why should you keep transmissions short when using a repeater?
To keep long-distance charges down
To give any listening non-hams a chance to respond
A long transmission may prevent someone with an emergency from using the repeater
To see if the receiving station operator is still awake
What is the proper way to break into a conversation on a repeater?
Wait for the end of a transmission and start calling the desired party
Shout, "break, break!" to show that you're eager to join the conversation
Turn on an amplifier and override whoever is talking
Say your call sign during a break between transmissions
What is the proper way to ask someone their location when using a repeater?
What is your 20?
Where are you?
Locations are not normally told by radio
What is your 12?
FM repeater operation on the 2 metre band uses one frequency for transmission and one for reception. The difference in frequency between the transmit and receive frequency is normally:
1 000 kHz
