==> IARU OPERATING AWARD FOR WORKED ALL CONTINENTS (WAC)
The IARU issues Worked-All-Continents certificates to amateur radio stations around the world that work all six continental areas.
Qualification for the WAC award is based on an examination by the International Secretariat, or a member-society, of the IARU of QSL cards that the applicant has received from other amateur stations in each of the six continental areas of the world. All contacts must be made from the same country or separate territory within the same continental area of the world.
All QSL cards (no photocopies) must show the mode and/or band for any endorsement applied for.
Contacts made on 10/18/24 MHz or via satellites are void for the 5-band certificate and 6-band endorsement. All contacts for the QRP endorsement must be made on or after January 1, 1985 while running a maximum power of 5 watts output or 10 watts input.
For amateurs in the United States and in an area without IARU
representation, the WAC application forms are available in MS Word and Adobe PDF format. Once completed, applications should be directed to the WAC Awards Manager, ARRL, 225 Main Street, Newington, CT USA 06111. After verification, the cards will be returned and the award sent soon afterward. Also, approved DXCC card checkers can verify WAC program applications. For the latest list of DXCC card checkers visit the ARRL website. There is a $13.00 fee for US applicants. Sufficient return postage, or, a self-addressed stamped envelope, is required for the return of QSL cards. US amateurs must have current ARRL membership. At the present time credits in the ARRL LogBook of The World (LoTW) system cannot be claimed for WAC credit. Applicants who have a current DXCC award in the DXCC computer system can apply for WAC by completing the WAC application form and sending it to the address noted above, listing credits to be claimed on the application form. In this case QSL cards are not required. Send questions to firstname.lastname@example.org.
