frequency? - ✔✔Simplex
Which of the following is a guideline when choosing an operating frequency for calling CQ? -
✔✔All of these choices are correct - listen to make sure that one else is using the frequency;
ask if the frequency is in use, make sure you are in your assigned band.
What should you do if another operator reports that your station's 2 meter signals were strong
just a moment ago, but now they are weak or distorted - ✔✔Try moving a few feet or
changing the direction of your antenna if possible, as reflections may e causing multi-path
distortion

using the VHF and UHF bands - ✔✔Horizontal
What can happen if the antennas at opposite ends of a VHF or UHF line of sight radio link are
not using the same polarization - ✔✔signals could be significantly weaker
When sing a directional antenna, how might your station be able to access a distant repeater if
buildings or obstructions are blocking the direct line of sight path? - ✔✔Try to find a path
that reflects signals to the repeater
What term is commonly used to describe the rapid fluttering sound sometimes heard from
mobile stations that are moving while transmitting - ✔✔picket fencing
,What type of wave carries radio signals between transmitting and receiving stations? -
✔✔electromagnetic
Which of the following is a likely cause of irregular fading of signals received by ionospheric
reflection - ✔✔Random combining of signals arriving via different paths
Which of the following results from the fact that skip signals retracted from the ionosphere are
elliptically polarized? - ✔✔Either vertically or horizontally polarized antennas may be used
for transmission or reception.
What may occur if data signals arrive via multiple paths? - ✔✔Error rates are likely to
increase
Which part of the atmosphere enables the propagation of radio signals around the world? -
✔✔the ionosphere
How might fog and light rain affect radio range on 10 meter and 6 meter bands - ✔✔Fog and
light rain will have little effect on these bands
What weather condition would decrease range at microwave frequencies? -
✔✔Precipitation
What must be considered to determine the minimum current capacity needed for a
transceiver's power supply? - ✔✔All of these choices are correct - efficiency of the
transmitter at full power output; receiver and control circuit power; power supply regulation
and heat dissipation
How might a computer be used as part of an amateur radio station? - ✔✔All of these choices
are correct - for logging contacts, for sending/receiving CW, and generating/decoding digital
signals

sound card provides audio to the radio's microphone input and converts received audio to
digital form
