Before an emergency occurs, be sure you know how to make a distress call on a frequency where hams are likely to be listening, such as a marine service net or a wide-coverage repeater frequency. Store at least one of these frequencies in your radio’s memories, if possible. Anyone, licensed or not, can use your radio equipment in an emergency to call for help on any frequency. You won’t have time to be looking at net directories in an emergency. Do the following things when you make a distress call.
