NXDN Programming


Recommended Posts

I scored a rather rare Kenwood NX-340U-K2 radio version. It does both analog/NXDN and covers the frequency range of 400 MHz to 470 MHz, perfect for the Ham 70cm band.




I'm looking for a tutorial on programming this radio, or NXDN in general.


I already have all of the operator and service manuals for the radio. In addition I have the technical doc's from the NXDN standards forum too. 


I registered for a NXDN ID at the same place I have my DMR ID. Just need to figure out what exactly all of the NXDN specific settings do. The help file for the software, KPG-169D V3.03, is rather brief. The license key I have for the software allows me to do both wide and narrow band FM on the analog channels.

Kenwood's dealer site has a pretty good set of training videos under "Kenwood University", but if you're not able to access that, I'm not aware of any other training type videos. Even the official training videos are more of a high level overview, rather than drilling into specifics of particular setups.


I've always been a Learn by Doing type of person - but it does help me get up to speed quicker when I've got a working template to go off of. Perhaps someone with NXDN experience could share a working codeplug for one of their systems as an example?

I own a NXDN 2 meter repeater in Newton Massachusetts and I’m involved in a few others in New England.

Cool. I’m looking for a basic write-up or how-to for programming a basic NXDN radio. The one in particular is a Kenwood NX-340U-K2. I got the radio very cheap since it turned out to be both read and write password protected. No way to reset back to factory defaults that I could find after a couple of weeks of intensive searching. I finally got a modified version of the programming software that allowed me to blow-by all of the password protections so I could write a blank code plug to the radio which disabled the old passwords. It works on any radio supported by that radio programming software version.


I’ve downloaded all of the current NXDN tech docs, radio user manuals and service guides for it. It’s a lot of material to read through, most of which nobody cares about unless you’re writing communications software for NXDN. I’m just looking for an explanation for the typical settings the Kenwood needs, both for simplex and repeater ops.

Right now I have the radio stored away until I get more info and time to play with it. I also have the DMR version of the above radio, TK-D340U.

Well programming a nxdn radio is fairly straightforward. The things you need to do program your ran (nxdn version of NAC) and talkgroups into the radio. One of the big things that kenwood's do is aliasing and newer icom's do that also. Aliasing is where the radio will transmit the radio alias instead of just the unit id number. If you plan on getting the radio onto the NXDN network you'll need to get a id assigned from radioid.net. 


As for settings for simplex and repeater ops. Just go into the NXDN setting page and program your id and talkgroups there. The NXDN network has a similar layout to DMR and P25NX systems. One useful source is http://www.nxdninfo.com/ they have a lot information on set up of radios. I own a bunch of kenwood and icom nxdn capable radios and I run a department where we maintain about a thousand radios system wide. There's really nothing scary in programming an nxdn radio.
