1. Explain what
radio is. Then discuss the following:
a. The differences
between broadcast radio and hobby radio
b. The differences between broadcasting and two-way communications
station call signs and how they are used in broadcast radio and amateur radio
phonetic alphabet and how it is used to communicate clearly.
2. Do the following:
a. Sketch a diagram
showing how radio waves travel locally and around the world. Explain how the broadcast radio stations WWV and WWVH can be
used to help determine what you will hear when you listen to a shortwave radio.
b. Explain the
difference between a DX and a local station. Discuss what the Federal Communications Commission (FCC) does and how it is different
from the International Telecommunications Union.
3. Do the following:
a. Draw a chart
of the electromagnetic spectrum covering 100 kilohertz (kHz) to 1,000 megahertz (MHz).
b. Label the
MF, HF, VHF, UHF, and microwave portions of the spectrum on your diagram.
c. Locate on
your chart at least eight radio services, such as AM and FM commercial broadcast, citizens band (CB), television, amateur
radio (at least four amateur radio bands), and public service (police and fire).
4. Explain how
radio waves carry information. Include in your explanation: transceiver, transmitter, receiver, amplifier, and antenna.
5. Do the following:
a. Explain the
differences between a block diagram and a schematic diagram.
b. Draw a block
diagram for a radio station that includes a transceiver, amplifier, microphone, antenna, and feed line.
c. Explain the
differences between an open circuit, a closed circuit, and a short circuit.
d. Draw eight
schematic symbols. Explain what three of the represented parts do. Find three electrical components to match to three of these
6. Explain the
safety precautions for working with radio gear, including the concept of grounding for direct current circuits, power outlets,
and antenna systems.
7. Visit a radio installation (an amateur radio station, broadcast station, or public service communications
center, for example) approved in advance by your counselor. Discuss what types of equipment you saw in use, how it was used,
what types of licenses required to operate and maintain the equipment, and the purpose of the station.
8. Find out about
three career opportunities in radio. Pick one and find out the education, training
and experience required for this profession. Discuss this with your counselor,
and explain why this profession might interest you.
9. Do ONE
of the following (a OR b OR c):
a. AMATEUR RADIO
(1) Tell why
the FCC has an amateur radio service. Describe some of the activities that amateur radio operators can do on the air, once
they have earned an amateur radio license.
proper call signs, Q signals, and abbreviations, carry on a 10-minute real or simulated ham radio contact using voice, Morse
code or digital mode. (Licensed amateur radio operators may substitute five QSL cards as evidence of contacts with amateur
radio operators from at least three different call districts.) Properly log the real or simulated ham radio contact and record
the signal report.
(3) Explain at
least five Q signals or amateur radio terms you hear while listening.
(4) Explain some
of the differences between the Technician, General and Extra Class license requirements and privileges. Explain who administers
amateur radio exams.
(5) Explain how
you would make an emergency call on voice or Morse code.
(6) Explain the
differences between handheld transceivers and home "base" transceivers. Explain the uses of mobile amateur radio transceivers
and amateur radio repeaters.
(1) Prepare a
program schedule for radio station "KBSA" of exactly one-half hour, including music, news, commercials, and proper station
identification. Record your program on audio tape or in a digital audio format using proper techniques.
(2) Listen to
and properly log 15 broadcast stations. Determine the program format and target audience for five of these stations.
(3) Explain at least eight terms used in commercial broadcasting, such as segue, cut, fade, continuity, remote,
Emergency Alert System, network, cue, dead air, PSA, and playlist.
(1) Listen across
several short-wave bands for four one-hour periods, - at least one period during the
daylight hours and at least one period at night. Log the stations properly and locate them geographically on a globe.
(2) For several
major foreign stations (BBC in Great Britain or HCJB in Ecuador, for example), list several frequency bands used by each.
Compare your daytime and nighttime logs; note the frequencies on which your selected stations were loudest during each session.
Explain differences in the signal strength from one period to the next.
