A category for DX groups and websites. DX'ing is a term used by radio enthusiasts to describe a hobby which involves receiving long distance radio signals.
Shortwave radio listeners who tune in to a far away broadcasting station are DX'ing. A long distance conversation between amateur radio operators or CB radio operators is also called DX'ing.
Conditions (weather, solar flares etc) must often be just right for successful DX'ing, so this hobby can be quite challenging.
