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
