Contests

Fox Hunt Contest

Rebooted this year — enjoy a traditional fox hunt tracking down hidden transmitters. Up for more of a challenge? Solve the hidden puzzle within the fox hunt to win the ultimate prize!

View full contest details and rules

Can It Ham Contest

Design and build a functioning amateur radio antenna using non-traditional or improvised materials (e.g. tin cans, coat hangers, umbrellas, plumbing pipe). If it looks absurd and still gets on the air, you're doing it right. HRV will have connectors, soldering stations, and some raw materials available.

Coordinate your radio frequency

Have the frequency your group is using added to our master list, or have us check if someone is already planning to use that space — online at ConHam or via email.

Call for Staff / VEs
