Once again McARCS will be participating in the great California Shakeout drill exercise on October 18, 2018]]

Shortly after 10:18 AM all local nets should activate and record participation via a net check in on the usual local net frequency. Check the]] NETS page to identify your local net. To avoid duplications, each operator should check into only one local net.

Starting at about 10:30 AM a county-wide net will be activated on the county-wide linked repeater system with a call for the usual local nets following in general the procedures of the Wednesday evening county-wide net. At this time only the number of participants in each local net will be transmitted and recorded.

To save time in the exercise, traffic relating to emergency conditions and damage reports will not be transmitted. Exception: If there is a true emergency requiring a public safety response, a Break Break Priority message can be transmitted to the net control station together with a “This is not a drill“ announcement.

There will be a separate call for those medical facilities that have indicated an interest in participating in the exercise and at which a licensed operator is present.

There will also be a call for school district offices facilities that have indicated an interest in participating in the exercise and at which a licensed operator is present.

There will be a complete exercise scenario distributed via email to all those known and will be posted here as well. Check back on this web site often for updates.
