Important Information for Reflector Operators – How to Connect to NXCore

Posted on by
Reply

The popularity of reflectors has grown by leaps an bounds in the past year. These reflectors give hotspot users a way to access NXDN talkgroups, and speak to other hotspot users. However, there are some important steps you must take, to ensure your reflector/talkgroup can also be heard on NXDN repeaters throughout the country.

STEP ONE: Configure your reflector’s NXDNreflector.ini file
Locate the Icom Network section of your .ini file, and configure it as follows:

[Icom Network]
Enabled=1
Address=flicom.nxcore.org
TGEnable= <your talkgroup ID here>
# TGDisable=3456
Debug=0

Any lines that start with a “#” can be left as-is. That symbol signifies a line that is commented-out, and will be ignored. Restart your reflector when done.

If you have any other lines that begin with “Address,” you must put a pound sign at the beginning of those lines. Failure to do so may cause conflicts in the network. Unused address lines can simply be deleted, if desired.

STEP TWO: Notify the Core admins

Alabama Link (31010) now on NXCore!

Effective today, All repeaters connected to the Florida NXCore server, have access to the Alabama Link Talkgroup, TG 31010. This is a multi-mode talkgroup, so you’ll hear users from D-Star, DMR, and Fusion, in addition to NXDN.

On all repeaters, it’s a dynamic talkgroup. Key your radio on Talkgroup 31010 to activate. It will remain active on your repeater for up to 15 minutes since your last transmission. However, when finished, please key Talkgroup 1200 to reconnect it to the local repeater, without waiting for the 15-minute period to lapse.

Look for more talkgroups coming soon.

Haiti Talkgroup 37224 Now on NXCore

Want to welcome to welcome the Hams from Haiti using hotspots on NXDN.
They have their TG setup using the Florida Icom NXCore server and the Haiti Reflector
hosted by W9CR.NET.

If you have an Icom repeater and would like to join the Florida NXCore Network, let us know.

NXCORE.ORG

Posted on by

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.

Suggestions to the NXDN Community

Posted on by

Here is a valid suggestion submitted to the community;

One thing I would like to see addressed is the ability to send and receive messages through connected repeaters.  NXDN Messaging is a very powerful tool!  I have a Windows messaging app I will be bringing to the Hamfest this weekend that could reduce reliance on the Internet for Hams with NXDN radios.  The ability to implement it here in West Central Florida is limited to the reach of the single repeater your station can hit.  We need to be able to overcome that limitation to make NXDN messaging more universally accepted.  Think about the potential impact for SKYWARN.

here is the reply and my comments
(I would like to hear from others too!)

You bring up a good point Paul, but I have been battling this for a while now.

While I can send data like the D-RATS terminal program on NXDN via the voice stream,
The SMS data is a bit more complex. The ETSI standards for it only talk about the SU through the rptr to SU, but very little of it is in the conventional code for multi-site transport. I will see if I can reach out to the Japan and get some more input put into this, while I do know that Type C Trunking will carry it out, I also know that an IP NXDN CONSOLE can So the same thing. Though the flow chart is IP to SU by way or the repeater, I think with a work on the IP side and some data runs and captures via ICOM NXDNIP protocol, this can be achieved for 2020. We have a diverse group of people who are good with code and can come up with something to make it work.

Keep in mind, standard sms is 1024 character, while EXTENDED sms is 4096.
Truncated CONSOLE NWS messages can be entered into the network if done correctly. I will have to test that with my Kenwood Console on our UHF statewide system to my radios, but the Icom Ver 2 and nx5000 and 3000 platforms will do upto 4096 sms.
I will put that on the board for sure, because, if we can have a restricted web input to generate Certain “canned” messages to listening radios, that would be a leap ahead of all things NXDN!

IF the MMDVM and hotspot communities put their thinking caps on, I am sure this can be a very powerful, and use tool to the SAR and Skywarn communities.

 

DULY NOTED!

Updated talkgroups on the FLICOM NXCORE

Posted on by

Here is the current list of repeaters and talkgroups, served by the Florida NXCore server.

nxdnrepeaters <– PDF file for downloading.

If you’re accessing the network through one of the repeaters in this list, you only need to make sure you have a memory channel programmed for each talkgroup you want to use. Optionally, some radios allow you to select a talkgroup from a list, without needing a separate channel.

Consult the user’s manual for your radio for specific instructions.

All dynamic groups are on a five-minute timer. Every time you key the radio on your desired talkgroup, the timer automatically resets.

This document may be freely shared wherever its information may be useful.

Ralph Betts, W4ORL

Posted on by

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.

WHERE DO I GET A NXDN UID (Number)

Posted on by
Reply

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!
