Quick Answer
Test your radio's distress communication at least once a month, or after any major maintenance, to ensure it functions properly in emergency situations.
Regular Maintenance
Test your radio’s distress communication at least once a month, or after any major maintenance, to ensure it functions properly in emergency situations. This includes checking the antenna, battery, and transmission settings. Perform a thorough check of the radio’s systems, paying attention to any malfunctioning components.
Transmission Testing
When testing your radio’s distress communication, send a Mayday call on the designated distress frequency (121.5 MHz for VHF or 2182 kHz for HF). Wait for 30 seconds to 1 minute to receive any responses, as emergency responders may not be able to respond immediately. If you don’t receive any responses, try re-sending the call and adjusting your transmission settings if necessary.
Practice and Preparation
In addition to regular testing, practice sending distress calls in a simulated survival situation. This will help you become familiar with the process and build your confidence in using the radio. It’s also essential to have a clear plan for when to send a distress call, such as during a life-threatening emergency or in a survival situation with no communication with your group.
