IDAS

This is Icom's version of the NXDN protocol. The abbreviation is Icom Digital Advanced System.

Please see the Icom IDAS System Features website for a complete description of the system features of IDAS.

Also see the Understanding IDAS trunking Thread in the forums area.

Can it be Decoded?

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

• The Whistler TRX-1 and TRX-2 with the NXDN upgrade can copy this mode. However, they can't trunk NXDN systems. Program trunked systems as conventional objects. See the How to improve NXDN Scanning thread and the NXDN Update Now Available Thread
• Use either Digital Speech Decoder (software package) or DSDPlus software, along with a scanner which, in many cases, will require a Discriminator Tap. You can also use a SDR with these applications without the need for modifications.

Data for Scanners

• The Digital Frequency Quick Import webtool can also be used to import frequencies into several modern scanners.
