What part didn't I get right?  I suppose one could set the amplitude to 0. But a really loud zero hz tone is still silence.

      Some entries have hard coded defaults where if you
        leave it out, it will default to something else, so if you want
        a silent telem, make a telemetry tone that is silent and set it
        as the tone.
        

        
        I think you'll need to set remotetx in [telemetry] to a
          silent tone. If you leave it out it will default to some
          hardcoded tone.  I use 
        

        
        |t(0,0,10,2048)    ; silent  tone.
      
    
    

    Uhm... not quite, Mike...

    

    A tone group is a set of 4 comma separated integers formatted as
      follows:

    (frequency1,frequency2,duration,amplitude)

    frequency1 and frequency2 must be a number between 0 and 3000.
      These specify the tone frequency in Hz.

      duration is the tone on time in Milliseconds. amplitude is the
      relative volume level of the tone or tones. This can be from 0 to
      8192.

    A tone group consisting of zeroes for amplitude and frequency
      will be sent as a silent period.

      A single frequency tone can be sent by setting frequency2 to zero.

    Note: There must be no spaces between the commas, numbers, or the
      parenthesis.
