          It sounds to me, like the squelch is wide open, and you're
          using usbradio.conf to define the pl tone(s).  If your squelch
          is wide open, you will hear that bit of squelch crash after
          the tone is dropped, and before the repeater drops.<br>
          <br>
          There are 2 ways to go on the settings, and I don't remember
          which is which so there's a 50/50 shot at this... but "as I
          recall" (and I'm not remembering well, these days) the Lower
          the number, the 'looser' the squelch.  <br>
          <br>
          For experimentation, you might try turning the tone
          requirement for the receiver off, and adjusting that value,
          while listening to the output of the repeater (while not
          hooked up to anyone) and determine where the squelch level
          should be.<br>
