PLEASE SHARE ON FB, PI-STAR, WHATCHAMACALIT, where ever there is use of the kenwoods with DMR hotspots. Thanks.
Okay, after battles and scraps, I want to pass along the follow:
1 Please refer to nxdninfo.com for OFFICIAL NXDN happenings on the commercial
Side of the NXDN WORLD WIDE NETWORK, www.nxdnradio.com is defunct and all
attempts to raise w2bui have failed. Unknown if he is a silent key or not. No one can confirm.
Also my name is Evans, not the minion Kevin.
2 Kenwood DMR with Dual Slot Direct Mode (the latest of most DMR releases) DOES NOT WORK WITH ANY HOT-SPOTS IN SIMPLEX MODE. Do not use it until the creators find a way to incorporate it Into the software. TURN IT OFF. This reverts to the old style of single time slot use. Until further notice.
It is with great sadness to inform our membership that OARC Director Ralph Betts W4ORL has become a Silent Key. Ralph contributed to OARC in a number of ways other than being a Director and he will be truly missed.
This is sudden and a total shock to all those who have known Ralph for years. We do not have any details of how Ralph passed. We will not speculate on the cause and will wait for any official cause to be announced by the family.
In the meantime, please keep Ralph’s family in your thoughts and prayers.

A little video on the Pi-Star
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

I have a note from Johnathan about his project. See Below!!
Hi All
I converted the MMDVM NXDN implementation over to very-narrow mode, aka NXDN 4800. I decided not to make it switchable to NXDN 9600 as it would then mean that people could choose to make their systems incompatible with existing networks. So NXDN 4800 it is.
It’s all been checked into GitHub for both the MMDVMHost and MMDVM firmware under the nxdn branch.
Currently it’ll be an RF only repeater, but it will allow you to play. I intend to get a simple NXDN reflector active and make a simple NXDN parrot available too. This will allow basic testing and communication until we can do something better.
There is a bug in the display code, maybe Nextion only, where the screen doesn’t update correctly at the end of a transmission, and I can’t find it! So any takers to look at that would be appreciated.
I’ve asked Andy CA6JAU to review my new filters for NXDN 4800 to make sure that they’re correct and that I have transmit amplitude (deviation) correct also. Even if they aren’t, you can try installing it and talking to yourself.

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.
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.

Greetings all,
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.
Thanks,
