As we all know, one of the missions of amateur radio operators around the world is to assist in establishing communications during disasters and emergencies. History is full of cases where amateur radio operators have been an irreplaceable link in ensuring communications during such critical situations.
What is Emergency Communication
Emergency communication is the exchange of electronic messages, most often voice data via radio communication, for transmitting and receiving distress signals. Emergency frequencies are intended exclusively for emergency communication – the exchange of radio-electronic messages during crises, disasters, and emergencies.
What is a Distress Signal and When to Use It
A distress signal is an internationally accepted way of requesting help. Signaling is carried out via radio communication, visual, or sound means. Sending such a signal means that human life is under immediate and unavoidable danger and that immediate assistance is needed. Transmitting a distress signal under any other circumstances is a gross violation of international laws, as well as most local laws.
