Amateur Radio groups in San Joaquin County use the California Health Alert Network (CAHAN) to notify hams when emergency communications help is required. CAHAN sends notifications to email, telephones, pagers, and other devices. Because CAHAN can be a little difficult to setup, will do the basic setup for our users. This can be changed later by the user, but our setting up the account insures that it works properly when the user receives it.
CAHAN first sends notifications via email. If the message isn’t acknowledged in a short time, the system begins calling the telephone numbers and reading a voice message. A user-selected PIN number is used to confirm receipt of a telephone message. CAHAN will try calling each number provided up to three times until the message is acknowledged.
This service is for emergency communicators in San Joaquin and adjoining (mutual aid) counties only.
After your account is created, you will receive additional information, including a setup guide, user name, and password via email.
CAHAN is used for emergencies, drills and exercises. Telephone calls are only placed in the case of actual emergenices where our assistance has been requested.
