County-Wide Communications Exercise & SET



Activation Number XSC-23-09T
Overview Dust off your go kits, brush up on procedures, and practice an end-to-end field deployment! This is as close to the real thing as you can get.

Everyone MUST sign up in advance, no drop ins.

Open to all amateur radio operators interested in emergency communications who have a current SCCo Disaster Service Worker (DSW) registration.

You need to arrive at Staging by 0815.

Individuals who do not have a current DSW registration with Santa Clara County can possibly sign-up to register when they arrive at the drill or sign a waiver.  You need to arrive no later than 0800 to start the DSW Registration process.

Purpose A county-wide communications exercise designed to practice mobilization, deployment and demobilization of amateur radio operations.  The activities are varied and have been designed to provide fun and education while, at the same time, developing experience with operating according to the standard procedures required for emergency operations.

We will operate much like we would during a real activation. You will need to be prepared to operate based on the assignment given, be able to program your radio when given a new frequency, have all the necessary go-kit forms available, and operate per the Performance Standards and Best Practice and your training.


Attendees have the option to sign up for various types of assignments. Click on the links below for more information about the type of assignment/activity and the equipment required:

There will be two shifts with varied activities that you can take part in. Each shift will be two hours.

All sign-ups should be done on-line, as far in advance of the event as possible, so the event staff can plan for the number of attendees.

Some activities require minimum qualifications, read the sign up pages.  For example, Net Control assignments require the participant to at least have a C4 Credential. If you are signed up for a Credential Evaluation you must have the other requirements for that Credential completed or receive approval from the Credential Program Manager.

Sign-Up To participate in this drill, you MUST sign-up in advance. You can select from up to two skill areas (one during each shift). Sign into the Activities database and look for the September 23rd County-wide Communications Exercise. Select the type of activity (Field, Net Control, Packet, or Shadow) you want to perform and then sign-up for one of the positions offered. Read the requirements for each position before signing up.

Travel to Drill

If you are a registered DSW, you are expected to use the Resource Net and follow standard Resource Net procedures.

If you are NOT a registered DSW, you will NOT use the Resource Net and will not be tracked. Travel to the drill on your own. You can Register for DSW before the drill but need to sign-up in advance.

Resource Net The following repeaters will be linked together for the drill and will function as the resource net:
  • AA6BT:  146.115 (+) 100.0  (Main; located in East San Jose)
  • N6NAC:  444.625 (+) 110.9  (South; best when South of San Jose intersection of Hwys 85 & 101)
  • W6ASH:  145.270 (+) 100.0  (North; best for North end of the county)


  • Program all the repeaters into your radio memory so you can easily switch between them while driving. 
    • If you are coming from the southern end of the county, you will need to switch from N6NAC to AA6BT approximately when you reach the 85 and 101 intersection in South San Jose.
    • If you are coming from the northern end of the county, you can probably stay on W6ASH the whole way, but may have to switch to another repeater as you near the park.
  • Remember that linked repeaters require you to insert extra delay.  Leave plenty of space before keying up.  Pause after keying up, before speaking.
  • Prior to departure from home:  Check into the Resource Net. When called, tell net control your starting mileage (last three digits of your odometer) and your street location. (Your odometer does not have a decimal point. If you see a decimal point, you're looking at your trip odometer.  We don't use that because it can be reset.  Switch to your odometer and provide the last three digits to net control).
  • While traveling:  Stay tuned to the Resource Net and respond to health and welfare checks by net control. When called, give your mileage and street location.
  • Upon arrival at the drill: Stay in your vehicle and contact Resource Net control to check out. You will be told to switch to the Staging Net (the frequency will be provided at that time). Do not exit your vehicle until you have successfully checked into the Staging Net. If you are unable to reach the staging net, return to the Resource Net and inform net control.
  • If you do not yet have a current county DSW registration, net control will not be able to officially activate you and you will not be covered under the DSW program until you reach the drill site and complete your DSW registration.
Net Usage Everyone is required to be on the proper net at the proper time. An ICS-205 Communications Plan will be provided at Staging. The Resource Net is used for travel to and from the event for registered DSWs. The Staging Net is used whenever you are not on an assignment or when traveling between staging and your assignment.  Assignments may involve other nets.  Be sure you always check-in and check-out properly when moving from one net to the other. Always pay attention to the net control operator for whichever net you are on and answer promptly when called.
Training Info Additional information on the disaster server worker program, resource net procedures and net types and usage can be found in the Fundamentals of Emergency Communications training course materials. If you have not taken this course, you are advised to review the course materials prior to the drill.

If you want a Credential Evaluation please sign up no later than Saturday, September 16th.

Lunch There is no specific time defined for a lunch break.  The drill will run continuously with only a short 30 minute break between shifts.  Attendees can stop and take their lunch/snack break in between assignments (30 minutes) or whenever it is convenient.
Check-Out After you have completed each assignment, check into the Staging Net and return to the Staging Area for re-assignment or check-out.  Be sure to turn in all paperwork and fill out an evaluation form so we can capture your feedback.
Travel Home If you do not desire to be tracked home, simply leave the drill after checking out of Staging. You will not be covered by DSW at this point.

If you do want to be tracked home, check into the Resource Net from your car, prior to leaving the park. Respond to Net Control H&W checks while in route, check out of the net when you arrive home. Alternatively, you can check out of the Resource Net at any time on your way home if you decide to go somewhere else.
