Many groups use DTMF decoders,already in common use. Its easy for any ham rig or repeater controller to encode. LiTZ (long tone zero) is already accepted as the universal call for help,I use it when sending weather alerts. Most modern ham rigs have DTMF decode capability,even my old Rad Shack 202 ! Why re-invent the wheel? Seasons Greetings and 73,Lee,N3APP
