NXDN stands for Next Generation Digital Narrowband   For an introduction to NXDN, please see last week's podcast at www.scannerschool.com/session43 NXDN Trunking comes in two classes: NXDN-C and NXDN-D NXDN-C is like most trunking systems.  There is a control channel and a set of voice channels. NXDN-D is similar to LTR Trunking, where you have no dedicated control channel.  Your users are listening to a home channel and any channel can be used as a voice channel Please be sure to view the session notes for all the sources on both last week's and this week's podcast All session notes with links to the items we talked about can be found on our website at www.scannerschool.com/session44   Please support the Scanner School podcast.  Visit www.scannerschool.com/support to see how you can help us.  Some of the ways you can support us won't cost you any additional money!
