Amateur stations can transmit without a license in an emergency situation to provide necessary communication assistance because the regulations allow for unlicensed operation under specific circumstances when there is an imminent danger to life or property. In such scenarios, operators can use their equipment to provide vital communication services when no other means are available. This flexibility is crucial, considering that amateur radio often serves as a critical communication resource during disasters, emergencies, or other situations where normal communication channels may be down.

Choices like a software upgrade, controlled experiments, or communications with local government agencies typically require a valid amateur radio license because they do not fall under the urgency or necessity defined for emergency situations. Thus, those activities would not justify operation without a license according to the regulations governing amateur radio.
