A dx'er is rather like an angler who has gone fishing. The angler seeks a catch of the biggest fish whilst the avid dx'er seeks the elusive 'long distance' contact.

Whether he/she be an amateur radio operator, short wave listener (s.w.l.'er) or even an a.m.b.c.b. dx'er (a.m. radio broadcast band dx'er}. Absolutely fascinating!.

Long distance in telecommunications, refers to telephone calls made outside a certain area, usually characterized by an area code outside of a local call area. Long distance calls usually carry long distance charges which, within certain nations, vary between phone companies and are the subject of much competition. International calls are calls made between different countries, and usually carry much higher charges.
