    B-003-15-01
    What does "connected" mean in a packet-radio link?
    A telephone link is working between two stations
    A message has reached an amateur station for local delivery
    A transmitting and receiving station are using a digipeater, so no other contacts can take place until they are finished
    A transmitting station is sending data to only one receiving station; it replies that the data is being received correctly

    B-003-15-02
    What does "monitoring" mean on a packet-radio frequency?
    A member of the Amateur Auxiliary is copying all messages
    A receiving station is displaying messages that may not be sent to it, and is not replying to any message
    A receiving station is displaying all messages sent to it, and replying that the messages are being received correctly
    Industry Canada is monitoring all messages

    B-003-15-03
    What is a digipeater?
    A repeater built using only digital electronics parts
    A repeater that changes audio signals to digital data
    A packet-radio station that retransmits only data that is marked to be retransmitted
    A packet-radio station that retransmits any data that it receives

    B-003-15-04
    What does "network" mean in packet radio?
    A way of connecting packet-radio stations so data can be sent over long distances
    A way of connecting terminal-node controllers by telephone so data can be sent over long distances
    The connections on terminal-node controllers
    The programming in a terminal-node controller that rejects other callers if a station is already connected

    B-003-15-05
    In packet-radio operation, what equipment connects to a terminal-node controller?
    A transceiver and a modem
    A DTMF keypad, a monitor and a transceiver
    A DTMF microphone, a monitor and a transceiver
    A transceiver and a terminal or computer system

    B-003-15-06
    How would you modulate a 2 meter FM transceiver to produce packet-radio emissions?
    Connect a terminal-node controller to the transceiver's microphone input
    Connect a terminal-node controller to interrupt the transceiver's carrier wave
    Connect a keyboard to the transceiver's microphone input
    Connect a DTMF key pad to the transceiver's microphone input

    B-003-15-07
    When selecting a RTTY transmitting frequency, what minimum frequency separation from a contact in progress should you allow (center to center) to minimize interference?
    Approximately 6 kHz
    Approximately 3 kHz
    250 to 500 Hz
    60 Hz

    B-003-15-08
