Questions tagged [emergency]

Questions about amateur radio emergency communication, either in support of emergency services or for use to report an emergency.

This tag is for questions about the use of amateur radio in support of public safety or disaster relief in a declared emergency, including any equipment, protocols, or techniques that are specifically applicable to emergency communications. This tag is not for general questions about the National Traffic System or nets in general, or about equipment that could be used for emergency communications, unless the question is specifically about that equipment's use in an emergency.

Also on topic is the use of amateur radio for personal safety to report an emergency, such as wilderness or maritime use. General questions about radios suitable for marine installation or HF radios for portable use are not applicable, only the use of those radios to report an emergency.

Questions about rules and regulations or about organizations that amateur radio operators work with in a time of emergency are also welcome.
