First NJ NXDN Repeater on the air and on the WW network

Posted on by

The N2WNS repeater system, Boonton, NJ, has been upgraded to the first NXDN amateur repeater in NJ. Located in northeast Morris County on 449.775, the N2WNS repeater system covers most of eastern Morris County, parts of Essex and Union counties towards NYC. The repeater will leverage “Mixed Mode” narrowband (11K0) analog and very narrow (4K0) NXDN. In digital mode, the system will be connected to the WW NXDN network using a TG of 65000 on RAN 1. In analog mode, the system will continue to provide IRLP connectivity via node 4437 and Echolink connectivity via node 753534. Local digital access will be on RAN 62 and analog access will continue to be on PL 151.4. The N2WNS repeater will continue to provide weather alerts via NOAA issued warnings. Questions can be directed to Bill, N2WNS via n2wns.radio (*at*) gmail.com

Californication? Yes. NX-5000 Multi Mode Kenwood, COMING SOON!

I had a nice chat with a California member of Kenwood, they are gearing up to get their rPi setup with their NXR-800, and get it installed and brought online soon!

I will post when it comes up and where to look for it.

Interested in joining the network with your ICOM or Kenwood NXDN repeater?
Your at the right place.

Search through the archive and posts to learn more.
I will be working on the HOW TO guide in the next few weeks and hope to have it
posted for both the ICOM’ers and Kenwood people.

October is the release of the 700/800MHz NX-5000. Lots of talk on Radio Reference
on this! The VHF and UHF will follow in December / January. And I will have HAM
Friendly pricing available as soon as I get the details. WARNING! It will not be cheap,
but you will get you monies worth for it.

Cheers!

NXDN in CT

More NXDN in CT

 K1KGQ/R is now full time operational VNFM NXDN, RAN 1, on 449.775 in Torrington CT.  Joel is working on connecting up to the WW network, likely before the fall of this year.

Also, we are working on setting up another UHF site in northeastern CT, one in western RI (if it doesn’t bug PAVE PAWS), and another in the south-central part of the state.

NXDN on trial in Torrington CT

From Cliff, K1IFF

I have an NXR810 on the air, mixed mode (WFM) and VN digital in Torrington CT.  It’s at K1KGQ’s site as a trial. 

Joel is thinking seriously about getting his own NXR and some mobiles.  After only 5 days, he is VERY impressed.

Anyone in the area, give it a try.  It’s on 449.775 (-), PL is 141.3, RAN1.  No internet connection yet at the site.

Status of the NXREF and What Is Happening

Greetings all,
Here is a quick run up of what is in the pressure cooker….
NXREF UPDATES TO ROLL OUT IN THE COMING MONTHS.

A & B; A Bug Fix for the Kenwood side of the NXREF. One is with the turn on / turn off messages, and the other is dealing with the heartbeat for the UDP ports, since KWD uses 2 UDP ports.

New Features: Talk Group Linking and Authentication, a simple Public PKM style (something like IRLP) to add security to the NXDN Network. If the access code does not match, no link will be established.
Talk Group Linking; this will allow for Local, Regional, State, or even Area Wide uses.
Florida uses TG 1200 for Florida Wide, and Tampa is using 1201 for West Central Florida. As an example.

If you have not become a member of the HAM_NXDN email group, this is a Yahoo group located at: http://groups.yahoo.com/group/ham_nxdn/
This is open to ALL HAMS World Wide, and talks about the use of NXDN Radios for the advancement of Ham Radio, and 6.25 Digital Technology.

That is it for now.

From Serdar:

Dear Gang,
We setup our new NXDN repeater (VHF- R2- 145.650 MHz) to new location over the 17th and 18th weekend of August.
You can find installation photos at:

We linked this repeater to our other NXDN repeater (VHF-R7-145.775 MHz) which is located at our club building via 5Ghz link. Everything seems working now. In next days, we are planning to re-establish NXDN Reflector link via Raspberry PI.

After some issues with our prior provider, I just bit the bullet and got a slice of a virtual server online for real…

This is an image of the last 24 hours of bandwidth usage since I got all the repeaters and other reflectors moved over to it… :)…

We’ll see now what a standard month brings so we can gauge utilization.

When adding a Kenwood repeater to the network… 2 things are required.

a) you MUST turn off the Over the Air Alias on both the repeater and any users radios.  If you don’t, there is a better than 50% chance that NO icom radio will hear your call which can be pretty frustrating when you’re on a WW linked system.

b) your repeater MUST run Very Narrow on the Digital side.  Icom does not support 12.5khz digital, only 6.25 and so the 2 systems are not compatible unless they both are set for 6.25khz… this is a Kenwood repeater setting btw.
