Curious about what ham radio operators do?

Stop by BREC’s Highland Road Park Observatory, 13800 Highland Road from 2 p.m. to 10 p.m. June 28 for American Radio Relay League Field Day.

Participants of all ages can learn how to communicate with other ham operators; send your name in Morse code and visit education stations.

Ham radios are invaluable in times of emergency, when cell phones and the Internet may be unavailable, a news release from BREC said.

Highland Road Park Observatory’s American Radio Relay League Field Day is open to the public and free.

HRPO is sponsored by BREC, LSU’s Department of Physics and Astronomy and the Baton Rouge Astronomical Society.

For more information, call the observatory at (225) 768-9948 or visit hrpo.lsu.edu.

Youths could enter the Best Looking Lemonade Stand contest and a Facebook contest.

Winners will receive a gift basket from Raising Cane’s Chicken Fingers and the Facebook winners will receive merchandise from the New Orleans Saints.

Winning the Baton Rouge area best overall award was the Kute Kidz Lemonade stand operated by Park Erielle, Ethan and Evan Curtis.
