KF4I – Palm Coast, Florida to come online

Thom Scott, KF4I, in Palm coast will be replacing 443.3000 with a mixed mode Kenwood NXDN NXR-810 shortly. Today (11/16/13) KD4EFM and KF4I installed
and brought online the Raspberry Pi that will be part of the NXREF system, and
fine-tuned it for temp operation at his home QTH. Once the network is installed and
made operational at the repeater site, the repeater will be moved and replacing the
existing 443.3000. Details on that will come later.

443.30000
RAN 1 / PL 107.2
WBFM Analog
VNFM NXDN.

This will allow coverage from Saint Augustine down into Dayton Beach using the World Wide NXDN network. From Orland, KJ4OVA covers up to the northern end of I-4 at I-95.

Welcome aboard Thom!

 

Links added…

I have added the links to the NXDN User ID, and the NXDN Repeater List, that is attached to my Google Drive. If you need to have your name added to the list, please
email me and I will add you in. The list is viewable to all, but edit rights are assigned.

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.

 

New Reflector online

Image

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.

Kenwood Info

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.

Tallahassee, FL now online!

Ok, so it’s probably time that I created some form of table of who’s what, where :)…

We just brought up a new Kenwood site today on VHF and Norm in Tallahassee will be adding a UHF site to that a bit later.

Yet another *FIRST*!

This morning we conducted a little test.  A Kenwood Repeater, connected to a 4G Wireless router, all external IP addresses are private and will not accept incoming port forward requests.

We successfully connected the Kenwood to the WW NXDN network and carried on a conversation. :).

Stealth IP now works on the Kenwood NXREF…. yeah, no more VPN, no more static IP address, no more 15 IP limit.  I think we’ve now shattered all the barriers …

Added Turkey – Yes, the Country

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

ICOM Repeater UDP Packet Audio Decoding

So, over the last few days, i have been developing an application that will take the icom udp stream that connects repeaters together , and started decoding the stream on my pc, so far the process is working very well, and hope to have some pretty screen shots up soon. Its a windows application, and does require the ownership of a DVSI Dongle.

Oh, yeah, did i mention its windows ONLY.. sorry linux/mac guys 🙂 no java here.

Seems I always forget one detail :)

For those that are looking to join in the fun.

We’re trying to allow for keeping local traffic local and net traffic on the net.  In order to do that I’ve built a way to filter on Talk Group (Kenwood calls this Group ID).  If you have TG 65000 programmed in your HT or Mobile and you key up, you will go out over the net side, if you have any other TG selected, you will stay local to your repeater.  The opposite is true as well.  The net won’t invade your local QSO until the NXREF sees no activity for a programmable amount of time, then it will allow net traffic back on the repeater.  You can force this to happen immediately if the NXREF see’s the 65000 TG transmitted.

Also to better separate us out.  For now we are all on RAN 1.  I can translate RAN’s on the Icom side, I can’t yet on the Kenwood side.

So bottom line,

To get on the net, takes RAN 1, TG 65000, any other RAN or TG and you’ll just be talking on your local repeater.
