WAC meaning in Radio Science ?

Answer:

What is Worked All Continents mean?

An amateur radio operating award is earned by an amateur radio operator for establishing two-way communication (or "working") with other amateur radio stations. It is often also called contesting. Contesting usually involves a competition to see who can contact the most stations in a set period of time on certain bands and within specific rules. Awards are sponsored by national amateur radio societies, radio enthusiast magazines, or amateur radio clubs, and aim to promote activity on the amateur radio bands. Each award has its own set of rules and fees. Some awards require the amateur radio operator to have contacted other stations in a certain number of countries, Maidenhead grid locators, or counties. Because amateur radio operators are forbidden by regulation to accept financial compensation for their on-air activity, award recipients generally only receive a certificate, wooden plaque, or a small trophy as recognition of their award.

Most amateur radio operating awards require that the applicant submit proof, such as QSL cards, of the contacts which satisfy the requirements of the award.

There are thousands of operating awards available. The most popular awards are the Worked All States award and the Worked All Continents award, and the more challenging Worked All Zones, DX Century Club (DXCC), Islands on the Air (IOTA) and VHF/UHF Century Club (VUCC) awards. DXCC is the most popular awards program, initially requiring amateurs to contact 100 of the 340 (as of 2015) separately designated countries and territories ("entities") in the world. Other popular awards include contacting remote islands, beaches, US counties, and lighthouses. Many awards are available for contacting amateurs in a particular country, region or city. Summits On The Air, or SOTA, tallies points towards awards to hams who broadcast from mountain elevations or make contact with those transmitting from them, for which events are scheduled periodically.
