Greetings all. Spent the better part of 1-28-18 merging and updating the spreedsheet for the UID lists. Right now I have some 403 listings that are confirmed and valid.
Please be sure to use the NXMANAGER.NET site, scroll to the bottom and enter your information into the database. I have pulled the link to the GOOGLE DRIVE sheet I had been using, and merged out all the dup’s and added the missing ones to it. I will N2WNS and make sure we have the database up to date and I will also work on getting it linked to our stuff here as well.
Thanks for your support.
JVCKENWOOD Corporation (http://www.jvckenwood.co.jp/en/) announces that the NXDN Common Air Interface (CAI) was accepted at the Study Group 5 (SG5) meeting of the International Telecommunications Union Radiocommunications Sector (ITU-R) held in November 2016 and in Report M.2014-3, published in February 2017. This inclusion is highly significant since it represents official recognition – by the organization in charge of international standards – of NXDN as an international digital land mobile system, paving the way for its even wider adoption on a global scale.
NXDN is an open standard narrowband digital protocol employing 6.25 kHz and 12.5 kHz FDMA technology to comply with frequency coordination requirements in many countries; it supports a comprehensive radio system including trunked, non-trunked and direct mobile-to-mobile communication. NXDN was developed by JVCKENWOOD in cooperation with Icom Incorporated to offer an alternative for the Land Mobile Radio (LMR) industry that would facilitate development of more affordable digital radio products that would satisfy the FCC narrowbanding mandate. It is also intended to help countries that lack sufficient frequency resources for their public safety agencies and business operators.
This future-proof protocol offers numerous advantages. For example, 6.25 kHz dual-channel systems can be configured to fit within a 12.5 kHz channel, effectively doubling spectrum efficiency compared to an analog FM system occupying the same channel. Two NXDN channels can be allocated as voice/voice, voice/data, or data/data. Compared to analog FM, it provides wider coverage and superior multipath characteristics, but at the same time NXDN systems support mixed digital/analog operation, thus facilitating smooth migration to a narrowband digital system. With these and other advantages such as clear voice quality and strong security, it has proved highly successful and the number of NXDN radio terminals supplied into mission-critical non-mission critical applications has grown rapidly. NXDN has truly become a leading digital protocol for mobile communications.
NXDN is implemented in the KENWOOD-brand NEXEDGE product range, which since 2008 has offered digital conventional and trunked radio solutions to meet the diverse requirements of a wide range of government and industry users. And 2015 saw the debut of Gen2, the second generation of NEXEDGE products, with enhanced features, flexibility and performance – including the capability of linking up to 1,000 sites or 24 networks. NEXEDGE solutions are leveraging the full potential of the NXDN protocol, now officially recognized by the ITU.
JVCKENWOOD Corporation is a global manufacturer specializing in Automotive and Professional System Solutions. It was reborn as one company in October 2011 through the merger of Victor Company of Japan, Limited (JVC) and Kenwood Corporation (Kenwood) three years after management integration.
JVCKENWOOD operates four business segments, Car Electronics, Professional Systems, Optical & Audio, and Entertainment Software with image, sound, and radio technologies, as well as infotainment and visual software. JVCKENWOOD creates excitement and peace of mind, while aiming to achieve profitable growth and become a business group that is widely trusted by society.
Going to start migrating the user database off of the google sheet and onto the last heard database site. It is located at http://nxmanager.weebly.com/ and the link will also be added to the right side column.
Update: 01-27-18; I am currently working on merging the database at this time. I will let you know when it has been completed and updated.

Good Day to all,
I want to make something clear that has come to my attention. When there are new users coming on board and the UID Or Talk Proceed Tone, or wrong group SELCALL PTT is used, please, don’t condemn these folks.
They are new members just like we all were at one time or another to NXDN. Promote this network like it is the best thing you have going. You use it, locally or on 65000, promote this network for more users and owners. 52 sites listed and only 39 on the network,
this is not a COUNTRY CLUB exclusive network folks. We promote the use and experiments of NXDN because it’s becoming the normal mode easily to acquire for some people. Just like DMR, but we hold ourselves a little higher than that side of
Digital. Digital is here and will be here for the long haul. Let’s not get in a twit over a Talk Proceed Tone, or dupe ID’s or wrong talk group setting in the PTT SELCALL. Help them out professionally. Because that is what we do.
I am super busy with commercial work I am about ready to explode. Your help to this makes things go better, and get stronger. I am still working with an independent group to create a software bridge between the Icoms and Kenwoods so we can patch 65000 back together. Right now asking for free help is very light, and this group I have approached is tied up with high level Stuff that makes their paychecks. Hang in there, it is in the works.
Let’s keep this rolling strong, 2 new repeater owners have joined the network, Ohio and another Canada station returned.
Thanks all. Seriously.
PS, look for the network to get a boost from hamradio2.0 as the editor has purchased a radio and will be doing some highlights on NXDN and Ham Radio. So yes, other people may not be talking, but they ARE LISTENING!

Greetings one and all Hams!
Orlando Hamfest coming up in February, I will be there! Hopefully I can show off the NX-5000 series radios while there as well.
Well, work has had me rather busy over the last 3 months, so I can’t really give a good update on what has been going on, but will pass this along.
NXREF and NXCORE will be getting a minor over-haul and some updates to them. For the NX-REF, I am working on re-tooling it to become a soft-bridge between the Icom and Kenwood IP infrastructure. Thus making it a bridge between the two platforms.
NX-Core is being looked over to improve a few functions and make it a little more versatile for the NXDN side of Digital Ham Radio.
At this time, there is no lead-in as to designing NX-Ref to interface into the DMR Network Breinmaster. YES, there will be experiments leading up to an interface, but will not be part of the CORE NXDN world wide network.
DV-MINI’s; My understanding is there are a few who are playing with the mini and have been able to link into the NX-Core with the home-brew NXDN hotspots in non-nxdn repeater areas. Looking to incorporate that into the next level release forthcoming.
Anyone who has articles or other items to add, please send them to me or to Cliff (K1IFF)
and we will get them posted here for others to read up on.
I am getting word here in Florida, two repeaters have been put up over in Brevard County
on VHF. I will work on getting that information updated in the repeater list linked over on the right side menu.
73’s and Happy Digital Ham’ing
Greetings and welcome to the NXDN Ham Radio Blog. Wanted to update a few thing and share a link.
We are working on designing a software “bridge” between the Kenwood’s and Icom’s. We now have several “core servers” around the U.S. with 2 of them here in Florida. If you’re interested in joining the NXDN network, please let me know and I will get you the information you need. We welcome any BRAND of NXDN manufacturers and encourage you to join the network, EVEN YOU WEST COAST PEOPLE OVER YAWNDER and ya’ll friends to the north of the border.
NXDN repeater search engine, well, thanks to repeater book, they now have a good listing of these around now. Here is the link to hit it up. (82 KNOWN NXDN systems out there)
I have been rather busy on the commercial side of Kenwood Type C trunking, putting up a few sites here and there, and working on getting our 36th site prep’ed and ready to go.
Hope you all have had a safe and great summer, fall is round’ the bend now. Know of any other NXDN’ers out there, spread the word. There is NO conFUSION that we run a great network here, and we keep things simple. We just let the one’s and zero’s flow!
The new NI4CE NXDN Repeater at Verna went on the air at 3:20 PM this afternoon. The repeater is operating on 444.3125 / 449.3125 RAN 1. Some tweaking to connect the repeater to the NXDN Worldwide Network is still needed but should be completed in the near day or two. In the meantime, we invite you to use the repeater on a local basis (TG1200).
We would also appreciate your signal reports. Send your Callsign, Location, Time of Day and Signal Strength (if you can read RSSI with your radio) to email@example.com.

It seems like we started talking about this a long ago. But the new NI4CE NXDN Repeater at Verna is poised for launch next week. The repeater and its several components have been assembled and are burning in. The new Telewave Antenna that will radiate the signal from 500′ AGL is configured and tested. And a tower crew is scheduled to put it on the tower this coming Monday. Of course, everything in Florida this time of year is “weather permitting”.
RX 444.3125 TX 449.3125 RAN-1 are the important numbers to program into your radio. TG 1200 will keep your traffic on the NI4CE system (Verna and Riverview). TG65000 will gate you to the remainder of the NXDN Worldwide Network.
Keep watching here for updates.

editors note Verna is located in Sarasota County near the town of Myakka City.
And this nice report from Ed in Brevard County Fl had this to say earlier also when repling to Paul
“Great news, we are trying to setup one here in Brevard. I think we found a tower. Will let you know once we get further information.”
Well, I broke my silence, yes, I made a video to demonstrate the FPP functions of the
NX-5000 series. Some of you who are on Radiorefrence.com will also see this in the
kenwood commercial group also.

The UHF repeater (443.400 +5 MHz), an Icom FR6000, was installed yesterday on Mount Uncanoonuc just outside of Manchester, NH. We did not get it connected to the network yet, but that process starts today. The plan is integrating into the Massachusetts hub in Swansea, MA.
Please send feedback if anyone detects any glitches such as one way audio and so forth.
