    When you say it doesn't trigger, do you mean that the receiver squelch
    doesn't open? Perhaps the TX delay on the transmitter needs to be a bit
    longer. Or you may wish to leave the squelch permanently open.. I find
    that to be the most effective method, and the soundmodem's carrier
    detection can handle that just fine.
