Contesting 101
Eliot Mayer, W1MJ
Presented to the Waltham Amateur Radio Association
May 31, 2006
-------------------------------------------------------------------------
The main purpose of this
presentation and hands-on training session is to help Field Day (FD)
participants enjoy the operating part of their experience. A second benefit is to help the audience
enjoy ham radio contesting in general, whether from their humble home station
or from a “big gun” operation.
Although FD is (1) an
emergency preparedness exercise, and (2) a social event, it also has an
on-the-air component that bears a close resemblance to a contest.
“Contesting (also known as radiosport) is a competitive activity pursued by amateur radio operators. In a contest, an amateur radio station, which may be operated by an individual or a team, seeks to contact as many other amateur radio stations as possible in a given period of time and exchange information. Rules for each competition define the amateur radio bands that may be used and the kind of information that must be exchanged in each contact. These contacts contribute to a score by which stations are ranked. Contest sponsors publish the results in magazines and on web sites.”
Over
the years, I have learned that contesting is not just for the “big guns” who
are out for first place. I, and many
others, enjoy contesting from our humble home stations. Achievable personal goals can be set, or
not. Such goal might include:
According to Andrew Roos, ZS1AN[2],
“Search and Pounce (S&P) means tuning around the band listening for stations calling CQ (or "TEST" as the case may be) and then calling them. It is the easiest way of operating for a beginner, as you can take your time to copy the callsign if necessary without any pressure (except the knowledge that time is points). Depending on band conditions, it may be worthwhile calling everyone you hear, or you may only want to call multipliers that you have not worked already. In either case, listen for the weaker signals that might get lost next to the strong stations (a narrow filter can do wonders), to make sure you don't miss out on a valuable multiplier just because there was a strong local station 500 Hz away.”
“Running - When a station can stay on one frequency calling CQ and working station after station, this is known as "running". If you can do it then it is a very effective way to make lots of QSOs, although often they will be from the same area so you may not accumulate as many multipliers as you could if you were "searching and pouncing" on needed multipliers. In order to "run" successfully, you need either to have a good signal, or to be a moderately rare multiplier, in order to attract sufficient callers and hold on to your frequency. You also need to be fairly competent at recognizing callsigns, whether CW or Phone, which may be buried in a pile-up. Nobody minds if you take 4 or 5 tries to figure out the callsign of a station when you are search and pouncing and the other station is calling CQ, since you can just listen to his or her CQ call 4 or 5 times without disturbing anyone, and only your own score will suffer. However if you call CQ and then take four or five attempts to get the callsign of the station coming back to you correct, then you had better be a very rare multiplier!”
A few notes specific to
Field Day:
According to the FD rules[3], there are no multipliers for “sections” or countries. All contacts are of equal value. But if you want to fight through the pileup to work Hawaii on 40 meters, just for the fun of it, go for it!
W1MHL,
running 100W, will be as loud as most FD stations. Therefore, “running” should be possible, though it would be best
to avoid the most crowded parts of the band.
Logging: Paper vs. Computer
Serious contesters now use computer
logging, but so do many casual contesters.
This year’s WARA FD will have one station with each method. Here are some pros and cons of computer
logging, compared to old-fashioned paper logging:
|
Computer Logging Pros |
Computer Logging Cons |
|
Instant checking for “dupes” (duplicate contacts). No need to maintain a “dupe sheet”. |
You must be able to type at a reasonable speed. |
|
The log is legible. |
You have to learn how to use the software. |
|
With control interface, frequency is automatically logged. |
As with any computer usage, you can lose data if you don’t
back it up periodically. |
|
On CW, most transmissions can be sent with a single
keystroke, with no errors. |
Uses more power on FD. |
|
Score
and hourly rates are available. |

For
“S&P”, band map will show stations you want to work when they are less
busy, and stations you’ve already worked. |
You
have to use a computer, from which you may want a break on the weekend. |
|
“Check”
window can help you with accurate callsign entry. |
|

Can
share “spots” (not applicable to FD) |

Paper Logging
Logging on paper requires, in addition to the log itself,
one or more dupe sheets. The dupe
(duplicate) sheet keeps track of all the stations worked, so as to avoid calling
the same stations multiple times. This
is necessary when search-and-pouncing is done, unless (1) you are making very
few contacts, or (2) have a photographic memory.
For FD, contacts can be made with
the same station on each band and mode.
Therefore, separate dupe sheets are needed for 20M CW, 20M SSB, 40M CW,
40M SSB, etc. Also for FD, these dupe
sheets, rather than the actual logs, must be submitted to the ARRL with the
clubs report.
Computer Logging
For FD, we will use “N1MM Logger”, an excellent program that can be
downloaded on the Internet free of charge[4]. You can practice using the program at home,
and, hopefully, on a spare laptop at the FD site.
If you’d like to practice computer logging,
and brush up on your CW at the same time, try Morse Runner by VE3NEA. This is like a flight simulator for CW
contesting, and is also available as a free download[5]. The logging function keys aren’t exactly the
same as N1MM Logger, but it is fairly easy to switch between the two.
Specifics
for Waltham ARA Field Day 2006
Information about the WARA 2006 FD
is available on the club web site[6]. It is also a good idea to read the ARRL
Field Day Rules. If you don’t get a
chance to do so in advance, a copy will be available at the site.
Our exchange will be “2A NH”. On phone, use standard phonetics, but it’s
OK to actually say the name of the state, “Whiskey One Mike Hotel Lima, Two
Alpha, New Hampshire”.
A list of sections will be available
at each station. The computer log can
display a list of valid sections, and will not allow you to enter an invalid
section.
For
computer logging with N1MM Logger:
·
When you start, type OPON or Ctrl-O and enter your
call. Your call appears in the Info
window.
·
Check “Running” if running, un-check for S&P. For SSB, we’re not using canned messages, so
this won’t matter. The same is true if
you want to send all CW by hand.
·
If you type a call and it turns gray, it’s a dupe. If running, it’s much quicker to just work
him again than to send him away, and maybe he didn’t have you in his log
anyway.
·
Use Space Bar or Tab to move between fields (call, exchange,
section).
·
To correct a call or exchange you already logged,
right-click on the log entry, and select Quick Edit. Fix the error and then hit Enter.
·
The band map shows you:
o
stations you have worked in gray,
o
stations you haven’t worked in blue; double-click to go try
again.
·
The Check window shows known calls. If you get “Unique”, it’s not necessarily a mistake,
but you might want to double check.
·
The ESM (Enter Sends Message) mode lets you use the Enter
key instead of most function keys. The
next message to be sent is highlighted.
Ctrl-M turns ESM on and off.
