WebA CTCSS tone is a Continuous Tone-Coded Squelch System, something brought over to the hobby from PMR. Basically what happens is a sub audible tone is superimposed on your transmission and the repeater recognises this and opens or re-transmits your signal without the need of the 1750kHz tone. In practice, you just key the mike and the repeater ... http://www.blackcatsystems.com/ipad-iphone-ipod-touch-audio-sound-app/Selcall-Selective-Calling-Tone-Generator-paging-DTMF-CCIR1-CCIR7-PCCIR-EIA-EEA-CCITT-EURO-NATEL-VDEW-MODAT-ZVEI1-ZVEI2-ZVEI3-PZVEI-DZVEI-PDZVEI-ICAO-CTCSS-CODAN-SELCALL-CTCSS-CCITT-Natel-CODAN.html
