SOS, XXX, and TTT

23 January 2010 | by Anthony K3NG  |  Share |   |  Leave a Comment (0)
Last season while watching Deadliest Catch on Discover Channel, several times I heard the distress call "PON PON". Doing a little research (errr... a Google search) I learned that there are several distress signals beyond the venerable and familiar MAYDAY or SOS:

Distress signal: "MAYDAY" (CW: SOS)
Urgency signal: "PAN PAN" (CW: XXX)
Safety signal: "SECURITE" (CW: TTT)

I'm curious why we don't discuss or support the usage of PAN PAN (XXX) and SECURITE (TTT) in amateur radio?
