# LDM Feeds

## Default LDM Feeds for EDEX

Data feeds are defined by the **ldmd.conf** file in `/awips2/ldm/etc/ldmd.conf`.  The default feeds that come "turned on" with our EDEX are the following:

    REQUEST NEXRAD3 "./p(DHR|DPR|DSP|DTA|DAA|HHC|N.P|N.Q|N.S|N.U|OHA)." idd.unidata.ucar.edu
    REQUEST FNEXRAD|IDS|DDPLUS ".*" idd.unidata.ucar.edu

    notifyme -vl - -h localhost -f NEXRAD3 -p DHR -o 360
    
To watch the same on a remote queue:
