    Most of the exciters I use in repeater service, or hot spot for
    matter, have a TOT in the firmware. I crank them all the way up.
    Sometimes that is not as long as I would like but I feel better. As
    Kevin says, there are USB radio interfaces available with timers.
    The rules in the US may have changed but I remember a time when a
    repeater required a control channel on 220 MHz and above. But I'm
    old (licensed in 1969) and things change. The "belt and suspenders"
    approach can be a good thing.<br>

                    There are no versions of Asterisk/app_rpt along with
                    hardware that are stable enough to prevent this
                    condition from ever happening.   <br>
                    <br>
                    You may want to consider a radio adapter that
                    disables the PTT when the application has crashed or
                    stopped, there's a hardware malfunction, or a
                    communications issue with the radio adapter.  The
                    URI doesn't currently have this functionality, but
                    there are several others that do.<br>
