The Azalea Coast Amateur Radio Club is hosting a worldwide ham radio operator event onboard Battleship North Carolina. The ship is NI4BK, and ham operators can call in to the ship via voice, digital or Morse Code. This is the perfect way to learn more about ham radio equipment, while also honoring those that lost their lives during Pearl Harbor. Radio operators that make contact will receive a special postcard verifying the contact after the event. USS North Carolina Battleship, 1 Battleship Road. Tuesday, 9 a.m.-5 p.m. Free.
