Every year since 1933, on the fourth weekend of June, amateur radio operators in the United States and Canada gather for their annual Field Day. Amateur radio operators -- ham radio enthusiasts -- aren't just hobbyists. Their equipment and skills make up an important part of disaster planning in many communities, including ours. The American Radio Relay League (ARRL) holds its annual field day to promote interest in amateur radio and, more importantly, to practice operating over a full 24 hours as its members would do during a real disaster.
The AALR site lists 1607 Field Day events this weekend, including a bunch of them in the Bay Area. Oakland's event, put on by the Oakland Radio Communication Association will be at Sequoia Arena, 10013 Skyline Blvd, across from Chabot Space and Science Center from 11 a.m
