Do you have something similar to this in rpt.conf? idrecording=|iW3SBA idtime=600000 ; id interval time (in ms) (optional) politeid=3000 ; time in milliseconds before ID timer Also, in "duplex=" modes 0 and 1, if the transmitter is idle, it will not turn on the transmitter to send an ID. Even if the timer is due. It will send the ID if the transmitter is already up though. Take a look at : http://ohnosec.org/drupal/node/128 http://ohnosec.org/drupal/node/129 http://ohnosec.org/drupal/node/87 And on http://ohnosec.org/drupal/node/150 (undocumented features) I find the following rptinactmacro Macro to execute when inactivity timer expires rptinacttime Inactivity timer time in seconds (0 seconds disables feature) But I've never tried them to see if they work.
