CB Cluster DX brings the worldwide DX cluster network to your iPhone and iPad. Live spots, band filters, watchlist alerts — built for the serious DX hunter.
Features
Built from the ground up for amateur radio operators. No bloat, just the data you need — fast, clean, and native iOS.
Live DX spots via the CRX cluster API with automatic Telnet fallback. Stay connected even when the primary feed is down.
Add callsigns or DXCC prefixes to your watchlist. Get a push notification the moment your target appears in the spot stream.
Filter by band, mode, continent or DXCC entity. Quickly slice through hundreds of spots to find exactly what matters.
Instant DXCC entity lookup for every spotted callsign. Flag, prefix, CQ zone and ITU zone shown at a glance.
160 metres through 10 metres, plus all three WARC bands. CW, SSB, FT8, RTTY — every mode in one unified stream.
Built with SwiftUI for iPhone and iPad. Dark mode, Dynamic Type, background refresh and clean Apple design guidelines throughout.
Live data
Every spot shows you what you need: who spotted it, on which frequency, with what comment — and how long ago. Filter by band in one tap.
