History NXDN

NXDN was created in 2003 with a joint venture of Kenwood and Icom.   The protocol was announced at IWCE in 2005 and the first units arrived in 2006.  It wasn't until 2017 that NXDN was published by the ITU-R as an international digital land mobile system.
NXDN was created to satisfy the 2005 FCC Narrowbanding mandate.  Originally created for business users, NXDN is used by public safety and even the military.

Overseeing NXDN development and standards is the NXDN Forum.  A 30 member community including JVC Kenwood, Icom, Anritsu, The Boeing Company, and Zetron.

NXDN Comes in 3 flavors

NXDN Standard (As defined by the CAI)
Kenwood's NEXEDGE
Icom's IDAS
NXDN operates using FDMA over 12.5kHz or 6.25kHz wide bandwidth.

Hi All
As you may be aware, things have been moving on steadily with the new NXDN clients; the gateway, parrot and reflector. There has been a lot of testing by VK2HK and VK4TUX leading me to find and squash a number of bugs. It's almost ready for a full release, just a few things to be sorted out.

There is already an existing NXDN network, and our system links into theirs very successfully. We will therefore, wherever possible, use the same TG numbers as they do. Currently we have 1200 and 505 linked, and I hope that 65000 will be linked soon.

Once the new code is deemed mature enough, I will allow a grace period for it to filter into distributions before having the old NXDN TG65000 closed down.

Then NXDN will be running at full strength and will join the other modes as a full member of the MMDVM clan.

☆ NXDN Startup Host – Select your preferred startup host.

Note: According to the Pi-Star Change Log, NXDN was added to MMDVMHost in version 3.4.10; however, there is no NXDN Gateway service yet (supposed to be coming soon). In the meantime, the NXDN service is hardcoded to use the single public reflector that is available.

☆ NXDN RAN – Enter your NXDN Random Access Number (RAN).

How to obtain an NXDN ID

How to obtain an NXDN ID:

Quick note: For NXDN ID’s, use the last 5 digits of your DMR ID or a number that is 1 to 5 digits in length. NXDN does not recognize number above 65,519, thank you for understanding!

“We understand there are duplicates that can happen, hence the using of OTAA (Over the Air Alias) is asked” Call Sign.

No they do not do training videos, hence my video. I set this up using the add on software ($299) and two Nexedge radios.
