DX Cluster
The DX Cluster is a worldwide network that shares real-time information about active DX stations. It's an essential tool for every DX hunter.
What is a Spot
A spot is an announcement signaling an active DX station. It contains:
- DX Callsign: the station's callsign (e.g., 3B8CW)
- Frequency: where they're transmitting (e.g., 14.025 MHz)
- Mode: CW, SSB, FT8, RTTY, etc.
- Spotter: who sent the spot
- Comment: additional info (split, QSL info)
- Time: when the spot was sent
Types of Spots
Spots can come from:
- Manual spots: sent by operators who heard the station
- Skimmers: automatically generated by software receivers decoding CW/FT8
- RBN (Reverse Beacon Network): network of CW skimmers detecting stations calling CQ
Skimmer spots are indicated with the -# suffix in the spotter's callsign.
Useful Filters
To avoid getting lost in the mass of spots, use filters:
- By band: focus on bands you want to operate
- By mode: CW, SSB, FT8, etc.
- By continent: if you're looking for a specific continent
- By country: if you need a specific DXCC
Most clusters allow you to set permanent filters on your account.
DX Strategies
Tips to maximize your success:
- Act quickly: rare stations disappear fast
- Check the frequency: listen before calling!
- Watch for split: many DX stations transmit on one frequency and listen on another
- Golden hours: sunrise and sunset offer the best opportunities
- Don't trust blindly: always verify spots, there can be errors
