iCluster

iCluster is an iPhone App for HAM, SWL (Short wave radio listeners) or for everybody who want’s to know, what’s going on on the amateur radio frequencies.

iCluster informs about

• which HAM has listened...
• ...at what time...
• ...to which HAM with a certain callsign...
• ...on which freqency.

In addition a comment will be displayed, informing about the quality or other useful information.


This App is connecting the so called international DX-Cluster database in realtime. The results are analyzed and displayed in an easy to read overview. iCluster is an ideal tool for amateur radio operators for field days or contests. But also unlicensed users can use iCluster to find out the frequencies for their shortwave scanner or short wave radio receiver.

Calls (the callsign of the operators) will be decoded automatically by the App. This allows even inexperienced users to know the countries of the operators.

On 'normal' days, the DX-Cluster list might even be long. However, on good conditions or contest times, the list might even be longer.

For this reason, the content can be filtered by frequency (e.g. 80m, 40m etc.) or mode (CW = Morse, Beakon or digital modes). Shortwave up to VHF frequencies are supported (from 160m to 6m and 70cm).

iCluster is available here in Apples AppStore.
