    End of radio transmission "click"

    Hello out there, I was wondering what the "click" or "tick" noise is at the end of a radio transmission. I hear it at the end of a 800 mhz radio transmission and some times the end of a VHF radio transmission. Its not MDC, MODAT, or DTMF. Just curious to what it is. Thanks!!!
