Amateur Radio
• Often is called “ham radio”
• Has consistently been a dependable and
reliable means of Communication in
emergencies
Simply Put – Ham Radio Works!
• Most of the time communication systems work
fine in spite their complexity
• When they become overloaded or fail Ham
radio operators Hams are frequently called to
provide communication where it really
matters
Conventional Communications
Systems May Fail
• Telephones, cell phones, Internet, trunk lines,
and satellite phones all go through many
vulnerable choke points.
• In an emergency they become overloaded
with non-Emergency traffic and they lack the
ability to prioritize messages
• Power failure can also cause telephone system
failure at the cell site,
switching center or at
the user end.
Wireless Communications
Systems May be Unavailable
• With extreme traffic volumes on normal 2-
way radio systems they may be completely
overloaded.
• Most agency radio systems have limited
resources (number of radio frequencies
available for communication).
Ham Radio is Different
• Hams have a practically unlimited number of
communication channels available.
• We have modes that can provide wireless
radio to internet access.
• We have low and medium power portable
radios for local communication.
• We have deployable HF (High Frequency)
radios with 100 or more watts of output
power.
Ham Radio is different
(continued)
• We can relay information through other hams
in their homes where they may have high gain
directional antennas and up to 1,500 watts of
transmit power, many with their own
emergency power capability.
• We can also use our own VHF/UHF repeaters
to extend our range just as the county and
police do with their own repeaters on ridges
and mountain tops.
By Selecting the Right Frequencies
We can communicate across town, across the
state or around the world
