Amateur radiosport is arguably the one sport with the most active
contestants anywhere in the world. The 2006 CQ Worldwide SSB contest saw
25,000 amateur radio operators take part in the single event on the
last weekend of October 2006. This is probably the most widely attended
contest but there are others running a close second and many that also sport
thousands of operators in a single weekend.
Most weekends of the year will see at least one contest but many weekends
will have more than one running simultaneously. Contest activity is greatest
in the fall and winter with the pace slowing in the spring and there is generally
light activity in the summer. We are of course referring to the seasons of
the northern hemisphere. But contesters from all continents participate in
Contesters compete for first place in their category. But unlike many
contests, amateur radiosport does not have any financial rewards which
would be illegal in ham radio events. Instead hams spend thousands of dollars to build
competitive stations to compete for paper certificates and at the very best
for a plaque. Some even spend thousands to travel to exotic locations to set
up a temporary contest station just for the purpose of giving another
multiplier for others to work in the contest. It seems that the pleasure and
fun of operating the contest is reward enough for most amateurs.
Types of Contests
Some contests promote worldwide activity such as the CQ Worldwide and
ARRL International contests while others are more focused on a given country
or region. There are contests for phone operators, CW and even RTTY is
popular. A few
are focused on PSK. The CQ Worldwide contests have separate events for each
of SSB, CW and RTTY which are held on different weekends so you can choose your
favourite mode or enter all three if you wish. This is also the case with
the Worked All Europe contests. There are also contests that combine modes,
such as QSO Parties or Field Day, that let you use both phone and CW in the
In some contests such as the CQ Worldwide everyone works everyone else in
the contest. In others there are restrictions. For example, in the ARRL
International stations in North America work only DX stations while DX
stations work only North America. In the All Asia contests, Asian stations
work everyone else in the world while stations outside of Asia can only work
|In the IARU HF World Championship contest everyone
works everyone on all HF bands not including WARC bands. Modes are
SSB and CW. In this example YL4HQ is a headquarters station in
Latvia. A SSB exchange is made with VE3XD.

While most contesting uses the HF bands including 10, 15, 20, 40, 80 and
sometimes 160 meters there are also contests for VHF and UHF. Some contests
only use a single band such as the ARRL 10 meter and ARRL 160 meter
contests. So there are plenty to choose from depending on your interests.
During the hours of a contest each station attempts to make contact with
other stations in the contest. A successful contact will result when there
has been an exchange of information including call sign and one or more
other items of information depending on the rules of the contest. Each
contest has specific rules stating what information must be exchanged to
make for a valid contact. This exchange always includes the station's call
sign plus data such as a signal report, zone, state or province, grid
locator, operator's age, year of licensing of the operator or the operator's
name. Rarely are more than two or three items of information required so the
exchange can be quite short in most contests.
For example in the CQ World Wide contest the exchange is the call sign, signal
report and the station's zone. So the author's station located in CQ zone 4
would send VE3XD 599 4 as the exchange. VE3XD would then receive a
similar report from the other station to complete the exchange. Each station
records the information in their contest log which will be submitted to the
contest organizers after the contest is over.
In the CQ WPX CW contest the exchange is call sign, signal report
and a consecutive serial number. In this contest VE3XD has found
ZL6QH on the 40 meter band and calls them. ZL6QH acknowledges VE3XD
and sends a report of 599 (abbreviated to 5NN) and a serial number
of 432. VE3XD then sends the report of 5NN and a serial number of
195 to complete the exchange.

the contest exchange.
In the ANARTS RTTY contest the exchange is call sign, signal report,
CQ zone and UTC time. In the sample video VE3XD is calling CQ and is
first answered by UR4U. Following a successful exchange VE2FK calls.
Again a successful exchange is made and VE3XD asks (QRZ) for any

In addition to the mode, contests can define different categories of
operation that can be chosen by the station to suit their preference or
capabilities. Contesters in different categories compete with others in the
same category to provide for some equality in the awards.
Not all contests have separate power categories but many do. Generally
there are three power categories:
- Low power usually permits 100 or 150 watts maximum.
- High power allows the legal limit generally considered to be 1500
watts but that can vary from country to country.
- Lastly there is QRP which is limited to 5 watts or less.
This category determines whether you have one or more operators and/or
transmitters at your station:
- Single operator. One and only one operator is present for the
duration of the contest. This operator performs all of the contesting
- Multi-Single (M/S). In this category one transmitter is used (except
for a special situation) but there can be more than one operator. Thus
different people can takes turns at operating relieving each other as
required. The special situation is that a second transmitter can be used
to work only new multipliers in the contest.
- Multi-Two (M/2). In M/2 there can be two transmitters and two
operators working simultaneously. Additional operators can be used to
take turns at either station to relieve the operators.
- Multi-Multi (M/M). This is the big contest station where there can
be a separate transmitter and operator for each band. Additional
operators can be available for relief.
In addition there can be variations such as Assisted where a single
operator station is permitted to use packet or telnet spots. This will
depend on the contest as some permit spotting for any and all operators
while other permit it only for Assisted category operators. Some contests
have a Rookie category for first time entrants in the contest. This helps to
promote the contest by attracting new blood to the event. You can see that
the rules can be a challenge to interpret at times.
A number of contests also have club and/or team categories. A club is a
group of contesters within a limited geographical region such as a circle of
a 275 Km radius. Clubs then submit their total score to compete with other
clubs around the world. Club contesting is popular in CQ and ARRL
international contests. A team is an ad hoc group that is formed prior to
the contest for the purpose of competing with other teams. Team competition
is popular in NAQP contesting.
To identify the winners in a contest a set of scoring rules are required
so that everyone is compared on the basis of their performance in the
contest. The final score is based on a formula that is different for each
contest but consistent within the individual contest.
Each contact or Q is awarded a point. There can also be points awarded
for multipliers such as contacting a station in each of the 40 CQ zones
around the world in the CQ World Wide contest. Or a multiplier can be given
for each U.S. station or Canadian province in an NAQP contest. In the WPX
contest a multiplier is given for each new call sign prefix worked.
For example, the rules for the North America QSO Party Phone contest
state that to calculate the score:
Multiply total valid contacts by the sum of the number of multipliers
worked on each band.
A multiplier is a state or province or any other North American country.
Thus a station who made 591 contacts with 138 multipliers on the 6 bands
between 160 and 10 meters would calculate
Score = 591 X 138 = 81,558
This is the claimed score that would be submitted to the contest
organizers along with a log of the contacts made during the contest.
It is necessary to consult the rules specified by each contest
organization to determine how the score is calculated for a contest.
Fortunately most contest software has already been taught the rules and will
automatically calculate your score as you log each contact.
Although you can log by hand on paper you will find this tedious
and error prone compared to computer logging. So as you are bitten
by the contesting bug don't wait too long to acquire software to
assist in your contest logging. The box on the right suggests some
very good contest software. Some of it is free and some has a small
fee to get a fully functional registered copy.

Good contest software will help you tremendously in your quest to become
a skilled contester. Software will alert you to duplicate contacts. It will
suggest potential call signs when you have entered a partial one. Software
can be interfaced with your radio so that it always knows what band and mode
you are operating on. You can use the software to send CW or phone messages
that have been pre-recorded. It can interface with your RTTY software and
some have RTTY built in. It can tell you what beam heading to use for that
DX station you can barely hear. It can tell you what your current rate of
contacts per hour are or the rate for the last 10 minutes. It can tell you how many mults you have and how much time can be profitably spent looking for new
mults. It can tell you your current score. Most of the programs in the box
above will do most of these things and some will do much more. Good
contesters rely on this data on an ongoing basis during the contest to help
in making informed decisions about their operating choices.
Don't confuse contest software with logging software used to record all
of your radio contacts over time. Contest software is designed for
contesting and not for daily logging.
Submitting a Log
|When a contest is over you will want to
submit your log to the contest sponsors. This is generally done
these days by email or an online form. If you have one of the
mentioned contest logging programs then all you need to do is have
the program generate the Cabrillo file to be sent to the address
announced by the organization. A good program will produce all of
the needed information to be sure that you will have your log
entered into the appropriate category.

Once your log has been submitted you will receive an
email acknowledging receipt or informed of a website where you can check for
logs that they have received. Now all you need to do is wait for the
announcement that you have won your category and the certificate or plaque
is in the mail. But don't despair if you weren't a winner. Most contestants
aren't first place winners but everyone had fun and that is really the main
purpose of the event.
