  1. The standard frequency offset (split) for 2 metre repeaters in New Zealand is:
    1. plus 600 kHz above 147 MHz, minus 600 kHz on or below 147 MHz
    2. plus 600 kHz below 147 MHz, minus 600 kHz on or above 147 MHz
    3. minus 5 MHz below 147 MHz, plus 5 MHz kHz on or above 147 MHz
    4. plus 5 MHz below 147 MHz, minus 5 MHz kHz on or above 147 MHz

  2. The purpose of a VOX unit in a transceiver is to:
    1. change from receiving to transmitting using the sound of the operator's voice
    2. check the transmitting frequency using the voice operated crystal
    3. enable a volume operated extension speaker for remote listening
    4. enable the variable oscillator crystal

  3. The "Q" signal which means "send faster" is:
    1. QRP
    2. QRQ
    3. QRS
    4. QRN

  4. Any length of transmission line may be made to appear as an infinitely long line by:
    1. shorting the line at the end
    2. leaving the line open at the end
    3. terminating the line in its characteristic impedance
    4. increasing the standing wave ratio above unity

  5. The velocity factor of a coaxial cable with solid polythene dielectric is about:
    1. 0.66
    2. 0.1
    3. 0.8
    4. 1.0

  6. The antenna in this diagram can be made to operate on several bands if the following item is installed at the points shown at 'X' in each wire:
    1. a capacitor
    2. an inductor
    3. a fuse
    4. a parallel-tuned trap

  7. A half-wave antenna resonant at 7100 kHz is approximately this long:
    1. 20 metres
    2. 40 metres
    3. 80 metres
    4. 160 metres
