DXing and DXpeditions

"DX" means a distant station, usually in another country, and especially a rare one. Our Hunt and Pileups chapters are written around parks. This page adds what's different when the station you want is a once-a-decade DXpedition to an island with a thousand people calling.

The DX ladder

• Your goal: most DXers chase DXCC, 100 DXCC entities confirmed. See the Awards ladder for what comes before and after it.
• Your station: you don't need a big one. A 100 W radio and a decent wire work DX on 20, 17 and 15 m when the bands are open. FT8 makes weak DX much easier. See WSJT-X.
• Your timing: propagation decides almost everything. Learn when each band opens toward each part of the world. See Technician HF & propagation.

DX clusters and spots

A DX cluster is a network where hams post "spots": a call sign, a frequency and a short comment. You can see spots on websites such as DX Summit, in most logging programs, and over telnet.

• A spot looks like this (made up): 14025.0 VP8XYZ UP 2 QSX 14027. The DX station is on 14.025 MHz and listening 2 kHz up.
• Don't trust the spot blindly. Busted calls and wrong frequencies are common. Listen until you hear the call sign.
• Don't spot yourself, and don't use the cluster to chat. The spots are for everyone.
• FT8 and CW stations also show up automatically on PSKReporter and the Reverse Beacon Network, which is handy for checking whether a path is open.

Split operation, step by step

A rare station working simplex would be buried by its own callers. Instead it transmits on one frequency and listens on another, usually a little higher: "UP 2" or "listening 5 to 10 up." That's split.

1. Listen to the DX on its frequency. Note where it says it's listening.
2. Turn on split on your radio. VFO A (or main) receives the DX. VFO B (or sub) is your transmit frequency. Check your manual: the button is usually labeled SPLIT.
3. Find the station it's working. Many radios let you listen briefly on your transmit VFO. Tune around the "up" window until you hear the caller who just got a reply. The DX often moves up or down slowly. Follow it.
4. Call just above or below that spot. Call once, with your full call sign, then listen.
5. When it answers you, give your report and nothing more: "KB3CMT 59 thanks."
6. Turn split off afterward, or you'll be calling CQ on a frequency you aren't listening to.

The classic mistake is forgetting split and transmitting on the DX frequency. You'll hear "UP! UP!" from a hundred people. It happens to everyone once. Check that split is on before every call.

FT8 DXpeditions often use "Fox and Hound" mode, or SuperFox (added in WSJT-X 2.7.0; see the SuperFox User Guide). Each has its own settings. Read the DXpedition's instructions before you call.

Manners: the DX Code of Conduct

The DX Code of Conduct is a short, widely shared list of habits. The IARU Region 1 and RSGB host it. In short:

• Listen, and keep listening, before you call. Only call if you can copy the DX properly.
• Make sure of the call sign yourself, rather than trusting the cluster.
• Never tune up on the DX frequency or in the slot where it's listening.
• Wait for the current contact to end. Send your full call, then listen. Don't call nonstop.
• Stay quiet when the DX calls someone else, asks for a call that isn't like yours, or asks for another region ("Japan only").
• Once it has your call right, don't repeat it. Be thankful, and earn other people's respect.

The same habits are in our Pileups and Ethics chapters.

Finding DXpeditions before they happen

Big DXpeditions publish band plans, pilot stations and online logs. Check the online log after a contact. If you're not in it, you can call again on that band and mode.

Getting the QSL

• LoTW counts for DXCC. Most large DXpeditions upload, sometimes after the trip.
• OQRS, often through Club Log, for a paper card, direct or via the bureau.
• Direct or bureau through the QSL manager listed on the station's QRZ page or announcement.

Details, fees and the ARRL bureau: Award platforms: QSL cards.

DXCC rule to know: all stations you use for one DXCC award must be in the same DXCC entity. Contacts with legally licensed remote-controlled stations are allowed (DXCC rules). Remote-station rules: Operating away.

DX and parks

POTA is international. Many activators are DX, and DX hunters chase US parks. The same split and listening habits apply when a DX park activator is running a pile. Log their park reference as usual (ADIF fields).

Habits / gotchas / checklist

• Heard the DX call myself, not just on the cluster.
• Split on, transmit VFO in the "up" window, checked before every call.
• Full call once, then listen. Quiet when it's not my turn.
• Checked the DXpedition's online log before calling again.
• Turned split off afterward.
• QSL by LoTW first, then OQRS or the listed manager.
