Configuring the DataBridge SDR2-CF

Figure 2.5. The Recording Parameters submenu. 

Overwrite-oldest mode: 

When overwrite is enabled, the SDR2-CF will delete 

the oldest file on the disk whenever recording starts and the CF card has less 
than 1 megabyte of free disk space.  Use this option with scheduled file 
closing (see below) to configure the SDR2-CF as a circular buffer that 
contains only the most recently received data.

logger.
