Introduction to DX NewsThis is basic information for people with no prior knowledge of Amateur Radio, DX and Radiosport. They are called radio amateurs, in some circles hams, and the hobby is officially specified as Amateur Radio Service, and dubbed as ham radio. A passive DXer is someone who is listening to distant commercial radio stations on both medium and short waves, trying to identify them. The main problem for DXers is that there are very few permanent Amateur Radio stations in far-off and underdeveloped places. The modern radio technology is based on digital processing of voice and image, so even Amateur Radio is affected.
