Amateur Radio Bands
Just as many of us have a favorite fast food that we come
back to time after time Radio Amateurs tend to have a favorite
band that they use more frequently than other bands. The
question of what band to use may be secondary to that favorite
band. But the first question should be what band(s) am I
licensed to use? From the beginning of the licensing process you
will find out what bands your license covers.
Next it is a matter of having the right equipment for the
bands you want to use. As an entry level license generally
covers VHF(2m) and UHF(70cm) and many beginning hams will use
one of both of these bands. Also hand-held single-band or
dual-band radios for these bands are affordable and don't
require a sophisticated antenna or power source. Most
metropolitan areas also have amateur repeaters to extend the
coverage when using VHF or UHF radios.
Band Restrictions
In addition to deciding what band to use there may
also be restrictions within the band depending on
your level of license. Canada and the U.S. each have
slightly different band allocations which amateurs in each
country must follow. See the sidebar for links to web
sites where the band plans are defined.
Also the world is divided into 3 ITU regions each of
which have their own band plan. These plans all have a
great deal of overlap so you can usually talk to anyone
anywhere providing you get onto a frequency acceptable to
both.

Popular Bands
So what are the bands that most Radio Amateurs use? The table
below shows bands that are relatively common and how and when
they are in use. Again your license will determine which bands
and what portions you are eligible to use.

* It should be noted that band conditions vary for many
reasons and thus all of these bands can at times take on the
characteristics of others. See the section on Propagation.
This table should be considered a general guideline.
HF Bands
For amateurs who have an interest in long distance
communication the HF (high frequency) bands will be of great
interest. These bands offer propagation
to all parts of the world at some time during the day, night or
season. Do you want to talk to Japan from the east coast or
Europe from the west? There will often be a time and a band
where this communication is possible.
During a sunspot high cycle conditions are best for the
higher HF frequencies and during a low the low frequencies are
often in demand with all kinds of variation in between.
Magazines such as QST and CQ Amateur Radio publish charts
monthly that predict the best propagation to different areas of
the world. These are just best guesses and will help you to
choose your times and bands but there is no substitute for
getting on the air.
Canadian and U.S. hams have different band allocations in the
HF area although there is a lot of common ground. The following
pages show a summary of the allocations in each country. For
complete details go to the corresponding RAC or ARRL web site
listed above.

Now that you have an idea of the band(s) you will be
operating how about some instruction on operating practices. The
section Basic Operating explains how to
make contacts and exchange information with other amateurs on
the air.
