WARNING: TO PREVENT FIRE OR
ELECTRICAL SHOCK DO NOT
EXPOSE TO RAIN OR MOISTURE
An appliance and cart combination should
be moved with care. Quick stops, excessive force and uneven surfaces may cause
the appliance and cart combination to
overturn.
The lightning flash with arrow head
symbol, within an equilateral triangle, is
intended to alert the user to the presence
of uninsulated “dangerous voltage” within
the product’s enclosure that may be of
sufficient magnitude to constitute a risk of
electric shock to persons.
The exclamation point within an equilateral
triangle is intended to alert the user to the
presence of important operating and
maintenance (servicing) instructions in the
literature accompanying the appliance.
WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT
EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. DO NOT
OPEN THE CABINET WHILE OPERATING. REFER SERVICING TO
QUALIFIED PERSONNEL ONLY.
CAUTION: TO PREVENT ELECTRIC SHOCK, DO NOT USE THE THREE WIRE
CORD WITH AN EXTENSION CORD RECEPTIACLE OR OTHER
OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO
PREVENT BLADE EXPOSURE.

22 The Electromagnetic Spectrum
Greenwich, England. In the past, World Time was known as
Greenwich Mean Time, today it is usually called Coordinated Universal Time, abbreviated as UTC. The military designates UTC
with the letter “Z” and refers to it as “Zulu”, which is the phonetic
pronouncer for “Z.” UTC is a 24 hour clock and the times are written in four digits with no punctuation. Thus, midnight is 0000
hours, 1pm is 1300 hours, and so on. To convert UTC to local
time, you will need to know how many time zones you are located
east or west of Greenwich, England. If you are located east of
Greenwich, you add the number of time zones, west of Greenwich
you subtract the number of time zones. Also, you need to remember that UTC never goes on Daylight or Summer Time, so your
offset will be different between summer and winter if you live in an
area that sets the clocks forward in summer.
14. Power Lines—An outside antenna system should not be located in the vicinity of
overhead power lines, other electric light or
power circuits, where it can fall into such
power lines or circuits. When installing an
outside antenna system, extreme care should
be taken to keep from touching such power
lines or circuits as contact with them may be
fatal.
15. Overloading—Do not overload wall outlets and extension cords as this can result in a
risk of fire or electric shock.
16. Object and Liquid Entry—Never push
objects of any kind into this product through
openings as they may touch dangerous voltage points or short-out parts that could result
in a fire or electric shock. Never spill liquid of
any kind on the product.
17. Servicing—Do not attempt to service this
product yourself as opening or removing
covers may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service personnel.
18. Damage Requiring Service—Unplug this
product from the wall outlet and refer servicing
to qualified service personnel under the following conditions:
a. When the power-supply cord or plug is
damaged.
b. If liquid has been spilled, or objects have
fallen into the product.
c. If the product has been exposed to rain or
water.
d. If the product does not operate normally by
following the operating instructions. Adjust
only those controls that are covered by the
operating instructions. An improper adjustment may result in damage and will often
require extensive work by a qualified
Important Safeguards cont’d 3
technician to restore the product to its normal
operation.
e. If the product has been dropped or the
cabinet has been damaged.
f. When the product exhibits a distinct change
in performance—this indicates a need for
service.
19. Replacement Parts—when replacement
parts are required, be sure the service technician has used replacement parts specified by
the manufacturer or have the same characteristics as the original parts. Unauthorized substitutes may result in fire, electric shock or
other hazards.
20. Safety Checks—Upon completion of any
service or repairs to this product, ask the
service technician to perform safety checks to
determine that the product is in proper operating condition.
21. Outdoor Antenna Grounding—Before
attempting to install this product, be sure the
antenna or cable system is grounded so as to
provide some protection against voltage
surges and built-up static charges.
a. Use No.10 AWG copper, No.8AWG aluminum, No.17AWB copper-clad steel or bronze
wire or larger, as ground wire.
b. Secure antenna lead-in and ground wires to
house with stand-off insulators spaced from 4
feet to 6 feet apart.
c. Mount antenna discharge unit as close as
possible to where lead-in enters house.
d. A driven rod may be used as the grounding
electrode where other types of electrode
systems do not exist. Refer to the National
Electric Code, ANSI/NFPA 70-1990 for information.
e. Use jumper wire not smaller than No.6
AWG copper or equivalent, when a separate
antenna grounding electrode is used.

of a disaster area for many days after the occurrence. In fact, the
ability of Hams to provide emergency communications is one of
the primary reasons Ham radio exists.
The primary modes heard on the Ham bands are CW (Morse
code, usually down at the lower end of each band), and voice
communications in the form of Single Sideband (SSB, there will be
more about SSB later on). There is also a smattering of other
modes: radioteletype, slow-scan TV, and other data communications methods. These signals require the use of special decoder
devices or computers with special decoding software in order to
read or view them. The Amateur Radio bands are as follows:
Frequency in kHz Band Name
3500-4000 80 Meters
7000-7300 40 Meters
10100-10150 30 Meters (CW/Data only)
14000-14350 20 Meters
21000-21450 15 Meters
24890-24990 12 Meters (Shared with Fixed Service)
Other Services
The Shortwave spectrum is also home to many other radio services, including ship-to-shore, transoceanic airlines, government,
military, and others. Often called “Utility Stations” or “Utes” for
short, their transmission modes include CW, AM voice, SSB voice,
radioteletype and data. The monitoring of Utes is a specialized
and rapidly changing area of the SWL hobby. It is beyond the
scope of this guide to provide more details, but there are books,
magazine columns, newsletters, and internet newsgroups if you
want more information.

World Time
Let’s say you want to listen to a BBC newscast at 5pm. But, is that
5pm in London where the program originates, 5pm in Southeast
Asia where the BBC relay transmitter is located, or 5pm in New
Zealand, where the intended audience lives?
To eliminate such problems, shortwave broadcast schedules are
kept in World Time. World Time is the local time at the Prime
Meridian, zero degrees of longitude, which runs through
