- The standard frequency offset (split) for 2 metre
repeaters in New Zealand
is:
- plus 600 kHz above 147 MHz, minus 600 kHz on or
below 147 MHz
- plus 600 kHz below 147 MHz, minus 600 kHz on or
above 147 MHz
- minus 5 MHz below 147 MHz, plus 5 MHz kHz on or
above 147 MHz
- plus 5 MHz below 147 MHz, minus 5 MHz kHz on or
above 147 MHz
- The purpose of a VOX unit in a transceiver is to:
- change from receiving to transmitting using the sound of
the operator's voice
- check the transmitting frequency using the voice
operated crystal
- enable a volume operated extension speaker for remote
listening
- enable the variable oscillator crystal
- The "Q" signal which means "send faster" is:
- QRP
- QRQ
- QRS
- QRN
- Any length of transmission line may be made to appear
as an infinitely
long line by:
- shorting the line at the end
- leaving the line open at the end
- terminating the line in its characteristic impedance
- increasing the standing wave ratio above unity
- The velocity factor of a coaxial cable with solid
polythene dielectric
is about:
- 0.66
- 0.1
- 0.8
- 1.0
-
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:
- a capacitor
- an inductor
- a fuse
- a parallel-tuned trap
- A half-wave antenna resonant at 7100 kHz is
approximately this long:
- 20 metres
- 40 metres
- 80 metres
- 160 metres
