CVARC Winter Field Day is January 29th

Conejo Valley Amateur Radio Club will hold Winter Field Day at Dos Vientos Park, 4801 Borchard Road, Newbury Park, CA 91320, from 10:00 AM to 3:00 PM on Saturday, January 29, 2022.

The purpose of Winter Field Day is to foster ham camaraderie, field operation, emergency operating preparedness, and just plain on-the-air, outdoor fun during winter for American, Canadian, and DX Hams.  Don’t let those winter doldrums keep you locked up in the house. Get out and play some radio!

The Conejo Recreation and Park District will not turn on the power to the electrical outlets at Dos Vientos until 12:30, so be prepared to power your rig on an emergency power source for at least the first two hours of Winter Field Day.

See you at the park!

Martin, AJ6CL
