MESAC meetings are held on the fourth Wednesday of each month at the City of Costa Mesa EOC, 99 Fair Drive, Costa Mesa, CA, at 1830 hours. The meetings are fun and informative. Often, there is a presentation on a relevant Ham Radio or emergency communications topic. Plans for future activities are discussed, assignments made, and reviews conducted of previous activities. The meetings are open to the public and we invite you to come meet us and find out about our organization.
