Every year, hams in the US and Canada observe the fourth full weekend in June as Field Day, considered the most important amateur radio weekend of the year. In Hawaii, however, amateur radio recognition will be going on a little longer: the state's governor, Josh Green, has proclaimed all of June to be Amateur Radio Month, in recognition of the 3400 hams operating in the Pacific region.The state has ties to wireless that go back more than 100 years, however. In 1914, its island of Oahu became home to a Marconi wireless telegraphy station. In 1916, the first transmissions were successfully sent to Japan from the US territory, marking the start of wireless communication between the two nations.
