Amateur Radio Type IV Communicator Credential

Published on September 05, 2025

The first credential for any operator is always the Communicator Type IV (C4) credential.  Holders of this credential have basic communications skills and standard equipment. They are able to perform basic field communications tasks, perhaps with some coaching. Typical assignments include checkpoints, observation points, and rovers. Unlike all subsequent credentials, C4 is evaluated by the Emergency Coordinator of the operator’s home city.

The prerequisites for the Communicator Type IV credential are basic and quite simple: 

• Be a Registered Emergency Services Volunteer and complete the City Volunteer DSW Registration
• Complete the SCC ARES Introduction to Emergency Communications training class
• Complete the SCC ARES Fundamentals of Emergency Communications training class
• Complete these 4 ICS/SEMS online classes

Use the following Type IV Checklist to make progress toward this certification.  The Palo Alto EC, Mr. Walter Underwood, can sign off on your accomplishments.

Once you achieve the Type IV, don't stop there.  There are other certifications you can obtain that will make you a more advanced radio operator.  Visit the Santa Clara County ARES credentialing website to learn more.  https://www.scc-ares-races.org/credentials
