[App_rpt-users] rpt.conf clarification

[Bob]

1) What is the purpose or function of the "/r" after the call sign in the
idtalkover example below?

      http://ohnosec.org/drupal/node/129

     "idtalkover=|iwa6zft/r ; Morse Code ID"

2) Is there a way of reducing the idtalkover volume (morse code ID or sound
file)? If so, how?

Thanks,
Bob
