Select YOUR DX Cluster
DX cluster is network of amateur warning, which is used for the exchange of operational DX-information. Most clusters are globally linked through short-amateur communications systems and Internet.
Any member of the cluster having contacted with an interesting DX-station on the air may send a short message (called "QSN", or "spot") indicating the station’s call-sign, frequency, time and his own comments. This information appears on monitors of other radio amateurs within the minutes.
DX cluster should allow amateur hams to make DX QSOs much easier. Unfortunately, the popularity of DX-cluster leads to the opposite result.
The appearance of rare spots makes a terrible "pile-up" on this frequency.
