ScanScope

ScanScope allows you to monitor radio traffic and to decode and to record the various identification schemes that are commonly in use.

ScanScope detect three methods (DCS, CTCSS, Selcal) by which radio transmissions are identified and distinguished on shared radio channels. The purpose of these techniques is to separate users into groups so that members of each group hear transmissions from their own group members but not transmissions from other groups. DCS (Digital-Coded Squelch) adds a continuous sub-audible baseband digital data pattern to the transmitted signal.
