EPIRB TX (Concept & Law)
Why faking distress beacons is illegal
#transmit#safety#epirb#406
What it does
SimpleThe EPIRB receiver let you read distress beacons. This page explains how those messages are built — but it is not something to transmit. Sending a fake distress beacon makes satellites summon real rescuers to a false emergency, which is dangerous and a serious crime. It's here only to explain how the life-saving format works.
How it works
SimpleThe beacon packs a country code, a unique ID, and sometimes a GPS position into a short coded burst that satellites relay to rescuers. That's why a fake one is so harmful — it looks exactly like a real cry for help.
How to use it, step by step
Simple- This is for understanding only — never transmit a distress beacon.
- Learn how the message carries an ID and position.
- Understand why a fake beacon endangers real rescues.
Examples
Message anatomy
Dissect the fields of a beacon ID (from a received self-test), safely.
Why it's protected
Understand how a false 406 burst wastes rescue resources and risks lives.
Tips & things to try
- Receive to learn; never transmit — false distress beacons are a serious crime.
- The EPIRB RX app is the safe, legal way to study the format.
