Ham Radio Contest Operating Basics
Ham radio contesting is competitive operating — stations around the world exchange brief, standardised information as many times as possible within a set time period, accumulating points based on the number of contacts and the multipliers worked (states, countries, grid squares, etc.). Contesting is one of the fastest ways to improve your operating skills, fill out your log with new states and countries, and understand how propagation actually behaves across different bands and times of day.
The contest exchange
Every contest has a defined exchange — the specific information that must be passed for a contact to count. A simple domestic contest might require just a signal report and state: "59 North Dakota." A larger international contest might require a signal report and a serial number or zone: "59 14" for CQ WW, where 14 is the CQ zone. The exchange is always specified in the contest rules and must be passed completely by both stations for the contact to be valid.
In most contests, the exchange is kept as brief as possible. Signal reports in contests are almost universally "59" (phone) or "599" (CW) regardless of the actual signal quality — this is a long-standing contesting convention that saves time, not dishonesty.
Scoring and multipliers
Contest scores are typically calculated as QSO points multiplied by multiplier count. A contact with a station in a new state, country, or zone counts as a multiplier — working a rare multiplier can be worth far more to your score than dozens of ordinary contacts. Understanding the multiplier structure for a given contest is key to operating strategy. For example, in the ARRL Sweepstakes, the multiplier is US states plus Canadian provinces — working all 50 states and 10 provinces gives a clean sweep and maximum multiplier.
Running — calling CQ
Running means parking on a frequency, calling CQ contest, and collecting callers as they come to you. A good run rate on 20m during a major contest can be 100–200 contacts per hour for a well-equipped station. Running requires a clear frequency and enough signal strength to attract callers. It is the highest-rate strategy but requires good operating skill to handle rapid-fire callers without errors. When running, keep the exchange crisp: hear their callsign, confirm it back, send your exchange, receive theirs, log it, and immediately call CQ again — the whole contact in 10–20 seconds.
Search and Pounce (S&P)
Search and Pounce means tuning across the band, finding stations that are running, and calling them for a contact. S&P is lower rate than running but allows you to pick up new multipliers efficiently by targeting specific states or countries. In S&P, when you find a running station, wait for them to finish a contact, then send your callsign once clearly. If they come back to you, send your exchange. Keep it brief — running stations are in a rhythm and don't want to slow down for a long ragchew exchange.
| Contest | When | Exchange | Good For |
|---|---|---|---|
| ARRL Sweepstakes (Phone) | November | Serial nr, category, callsign, section | US domestic — clean sweep challenge |
| ARRL Sweepstakes (CW) | November | Same as phone | Best CW contest for US operators |
| CQ WW DX (Phone) | Last weekend October | RS + CQ zone | Largest contest — worldwide DX |
| CQ WW DX (CW) | Last weekend November | RST + CQ zone | Largest CW contest in the world |
| ARRL DX (Phone) | Third weekend February | RS + state/province or power | US works the world |
| CQ WPX (Phone) | Last weekend May | RS + serial number | Easy exchange — good for beginners |
| Field Day | 4th weekend June | Class + section | Best first contest — outdoor/portable |
| State QSO Parties | Varies by state | RS + county or section | Short, friendly, good for new contesters |
Do I need a powerful station to participate in contests?
No — many operators participate in contests from low-power or QRP stations with simple antennas. Contest categories specifically accommodate low power (100W and under) and QRP (5W and under). A simple dipole at 100W will make hundreds of contacts in a major contest. The goal for new contesters should be having fun and building skills, not winning — winning is for later.
What logging software should I use for contests?
N1MM Logger+ is the most widely used free contest logging software for Windows and is the de facto standard for serious contesters. It supports virtually every major contest, generates Cabrillo log files for submission, and integrates with radios via CAT control. For Mac users, RUMlogNG and MacLoggerDX are options. Log4OM and DXKeeper are good general logging programs with contest support.
What is a Cabrillo file?
Cabrillo is the standard log submission format for most major contests. It is a plain text file with a specific header and contact format that the contest sponsor uses to check and score your log. Your logging software generates this file automatically. After the contest, you submit the Cabrillo file to the contest sponsor via their web upload portal, usually within a week of the contest end.
Can I participate in a contest without submitting a log?
Yes — you can operate in a contest and make contacts without submitting a log. Your contacts still count for the stations you work, and you get all the practice benefits. Many new contesters operate their first few contests this way before they feel confident submitting. There is also a Check Log category in some contests for stations that want their log checked for errors but not ranked.
