It's the Super Bowl of amateur radio operating and it will happen this weekend.
Ham radio operators will take part in the American Radio Relay League's Field Day -- an international event that asks operators and their equipment to face the elements and communicate from an outdoor post.
About 30 ham operators from the Douglas County Amateur Radio Club will set up shop under a shelter at Wells Overlook Park, four miles south of Lawrence just east of U.S. Highway 59 on Douglas County Road 458. Hams will have to rely on generators and will fight a lot of interference.
Club members expect to make their first contacts at 1 p.m. Saturday and operate non-stop until noon Sunday.
The idea is ``learning how to operate under the most severe conditions,'' said Bob Rainbolt, a Douglas County club member. It's an emergency exercise.
The goals during Field Day are to contact as many other stations as possible and make a short exchange with them. Field Day is an international event but most contacts will be made in Canada and the United States, he said.
A ham operators' newsletter will print a club's results in November, Rainbolt said. A club then can determine what it needs to improve on.
``It's really the biggest event in amateur radio,'' he said.
The Douglas County Amateur Radio Club has been participating in Field Day since 1971. It's always the fourth weekend in June.
The public is invited to come out and see the stations in operation.
