the Amateur Radio Service precludes the development of a professional sport. In addition to the recognition of their peers, winners in radio contests do, however, often receive paper certificates, wooden plaques, trophies, engraved gavels, or medals in recognition of their achievements. Some contests provide trophies of nominal economic value that highlight their local agricultural or cultural heritage, such as smoked salmon (for the Washington State Salmon Run contest) or a bottle of wine (for the California QSO Party).
