Introduction

The NXDN (Next Generation Digital Narrowband) common air interface protocol, which was developed jointly by ICOM and Kenwood, uses Frequency Division Multiple Access (FDMA), employing a 4-level FSK modulation scheme. These companies and others together form the NXDN Forum.

Kenwood's brand for NXDN equipment is "NEXEDGE", while Icom's brand for NXDN equipment is "IDAS", or Icom Digital Advanced System.

Who are the Users?

  • Click on the NDXN category at the bottom of this page, and select the various regions to see if there are listings in this wiki. More information might be found in the trunking tab of your state in the RR Database; however, the RRDB currently does not fully support NXDN listings.
  • You can use the Digital Frequency NXDN Search webtool to search by county for frequencies authorized to use NXDN (information extracted from the FCC database)
  • The Digital Frequency Quick Import webtool can also be used to import frequencies into several modern scanners.


Can it be Decoded?

Apart from using an actual Kenwood or Icom radio, the following methods are possible;
