Just letting everyone know, development of a SOFT-bridge between the cores is in the works at this time, not ETA due to current events, but the R&D on it is on the books and
being worked out.
The SOFT-Bridge will allow us to join the Kenwood and Icom cores with a data pipe that
allows us to have a seamless network between both Icom and Kenwood repeater owners. Basically a transparent bridge. Hope to have more information on this when it becomes available.

nxcore.org website to a nasty hacker hit, I am in the process of rebuilding it and giving it a facelift and more up to date look. nxcoreorg is the server farm hosting the world wide nxdn network connections for the Icom and Kenwood networks. The last heard lists and other information along with the code will get a fresh look and once over by the nxcore developers and admins after the new year. More on this when it comes. Stay tuned here for more information.

Here is a list of viewable dashboards for the NXDN WW Network.

Many have been pointed to a Google Spreadsheet style location, a new site has already, taking over the role of assigning ID’s.
The site is http://radioid.net
Radio ID is the master site for obtaining DMR, NXDN ID’s for amatuer use.
P25 ID’s can also use the DMR ID format, which some people follow that ID use also.
SO, please, kindly keep it within the parameters of 1 to 65519, and even though you CAN enter your full DMR ID, please register with radioid.net and follow all instructions withing the site.
Some additional information I wanted to put out:
For MMDVM email List go to: https://groups.yahoo.com/neo/groups/mmdvm/info
For the FaceBook PiStar group: https://www.facebook.com/groups/pistar/
I will add this to the Side Links area also.
Thanks and Welcome newcomers!

What is all this buzz about MMDVM and NXDN and ???????? other homebrew kits that are joining the Digital Ham Radio Era?
Well, like most forms of digital technology comes advancement of it. In this case it came from Jonathan Naylor G4KLX and his project for D-Star, Fusion and P25 (aka P25NX).
*I only know of those modes from Jonathan
But for some of you, you already know what it is and does. For others, it’s where you can take micro-computing to the next communications level, and have a “repeater controller” doing all the hard work with simple radio gear, and OR a hotspot 2-way now.
Here is where things stand at the moment, from the MMDVM Yahoo group, by way of Jonathan:
“I have merged he NXDN branch for both the modem firmware and the host into master. This means that the default version of the code is now NXDN enabled.
It has basic networking built-in, talking to the single MMDVM NXDN reflector. I posted details of how to use it a couple of weeks ago. I am working on making the software compatible with the official NXDN amateur network, and in due course, that, along with some form of gateway will be released. At that time the MMDVM NXDN reflector will be retired.
Please note that the extra processing load of the NXDN code means that it isn’t possible to run five modes on an Arduino Due. Aside from NXDN, D-Star and DMR are the next heaviest protocols for processing, so it may be possible to run (say) NXDN and P25 on a Due, and maybe more. The more powerful STM32 and Teensy based systems can easily run all five modes. I believe firmware for the ZUMSpot and MMDVM_HS boards will also be available soon.
In unrelated news. I’ve been adding FCS support into the YSF Gateway and taking the opportunity to clean the code up also. I did a first test this evening trying to log into FCS001-20 but with no success 🙁 It’s early days though.
Jonathan G4KLX ”
So with that being said, the next level of NXDN and the Homebrew world is network linking, which is still being tested at this time, though the MMDVM network has a function for linking, it is not currently connected to the NXCore 65000 relm at this time.
I will let you know when that chapter comes into play, but do expect to see a SURGE of new users to say hello to!
Thanks

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 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!

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:
http://www.flickr.com/photos/burcakcubukcu/sets/72157635115017614/
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.
Today we brought up a club in Turkey onto the WW NXDN network. This proved that we can do Kenwoods without a VPN, and it proved that we can make them work over multiple hops. I still think there is a gremlin or two to be worked out but Say Hi to The gang from Turkey.
Hi Alan,
Thank you very much for your great effort. I think we did :-))
I’m attaching the photos again. You can use them on your blog
