The Orlando Amateur Radio Club is hosting the 74th Annual Orlando HamCation February 7-9, 2020 at the Central Florida Fairgrounds and Expo Park. HamCation is the second-largest ham radio convention in the United States, with the inaugural event dating back to 1946. Since the first event, HamCation has continued to grow in size. The 2019 convention saw 23,700 attendees, a record number for the event.

This convention is a celebration of ham radio, also known as amateur radio. Amateur radio use in the United States dates back to the early 1900s and continues to be used today for both emergency situations and as a means for daily communication between ham radio operators.
