The annual U.S. ham radio Field Day will be held Saturday and Sunday.

Field Day is an emergency exercise in which hams assemble a radio station away from their homes using alternative power sources such as batteries, portable generators, or solar energy for 24 hours from Saturday at 1 p.m. until Sunday at 1 p.m. They will be making as many contacts in the U.S. and foreign countries as possible.

Local ham radio operators will be set up at the UW–Platteville Engineering Hall parking lot for the 24-hour exercise.
