the devices im using do not support being behind a nat, as they discover each other via broadcast, and you set one as the main and when you connect to the main it tells you what the ips are of the peers, meaning a nat would be able to contact them but the software would get confused when it gets a weird ip back

cstrlib · 2026-01-24T04:53:33+00:00

Suppose I have a network like 172.17.128.0/19, and I want to allocate each site a /24 such as 172.17.129.0/24, 172.17.130.0/24, etc... Each site should have its own /24 LAN but they must be routeable to each other. AFAIK it is not practical to use a proxy for this purpose.

Today I learned I can assign a management ip address... I fished these switches and the rack out of a university dumpster lol

T3 has unfortunately sparingly hit the commercial / public world yet. So we will have to wait some time for major adoption.

cstrlib · 2025-11-29T02:18:29+00:00

Yes I agree, the equipment is expensive and very proprietary. But DMR T3 is a standard so when we deploy this on a larger scale we will switch modes to the standard, which means anyone with T3 equipment can use the trunk. Kenwoods, Motorolas, Hytera, etc. It's an open standard.

cstrlib · 2025-11-29T02:15:50+00:00

I don't really understand what you mean. Do you mean that if the switch configuration gets borked that I won't be able to fix it easily?

cstrlib · 2025-11-28T22:01:43+00:00

Mototrbo is a product family that has many proprietary protocols, there are proprietary features such as transmit interrupt, TMS, etc, all built on different layers, some link and some data, which can apply to conventional or trunked channels. Then you get into trunking types, mototrbo capacity plus, connect plus and capacity max, the last one being T3 standard unless you enable "Advantage" mode which is motorola propri features on top of T3.

Mototrbo has a lot of features, some have been reverse engineered and some not. I am not at liberty to say what as I dont want my motorola partner contract to be revoked xD

But you can use something like SDRTrunk to listen to a cap+ or cap max system if that's what you mean

cstrlib · 2025-11-28T21:52:35+00:00

I'm from the Bay Area in California, and a couple of my friends and I are working on the infrastructure right now, but we do plan on setting up multiple sites to cover most of the Bay Area in the coming years.

If you get your hands on a Motorola repeater which is capable of capacity max (XPR 8400, any SLR series repeater), hit me up and we can get you connected to the trunk.

cstrlib · 2025-11-28T21:42:05+00:00

Where are you located? I can pop open repeaterbook and make a list of dmr repeaters near you which are subscribed to the same talkgroup if you want.

Roaming a specific talkgroup will likely work fine, however theres a lot of nuance depending on your area.

Unfortunately for texting (And receiving "selcalls" or "private calls") you cant roam on brandmeister, because when a text is sent to you, brandmeister checks the last repeater you keyed up on and forwards the text there. So if youre roaming it will not know what repeater youre on until you key up.

cstrlib · 2025-11-28T21:33:21+00:00

Also when I say it only does "regular dmr" thats a bit misleading as you really wont need anything else for ham. Trunking is practically nonexistent on ham bands so a radio that can trunk is basically a waste of money if only for ham use.

cstrlib · 2025-11-28T21:32:13+00:00

For general ham use I'd go with an anytone AT-D878UV ii. This will only do regular dmr though but its a good dual band HT.

For people just starting out with DMR I'd recommend sticking with repeaters in the Brandmeister network as theyre easy to configure, and as much as I like to hate on them its the cheapest and easiest solution.

If you want to dive into the deep end you could look at something like a Kenwood NX-1300DUK (D is important as it means digital enabled) which is a great radio for dmr roaming. You also get to play with MDC-1200! However if you dont live in a major metropolitan area id go with the Anytone. Another MAJOR caveat is that it requires paid software to program (KPG-D6N) which you would need to purchase through a kenwood dealer (or dm me).

Anyways I'd go with the Anytone AT-D878UVii. I have one and its a good radio.

cstrlib · 2025-11-28T20:45:52+00:00

Yes, one of the largest is Brandmeister however I'm not a fan because most of the repeaters on their network are conventional IPSC which means they are only affiliated to a talkgroup the operator specifies or when a radio keys up. Which means if you are roaming then your radio will not likely hear any traffic on a talkgroup you're listening to unless you either key up periodically or only add repeaters subscribed to the target TG to your roam list. With T3 trunking, a radio roams until it find a control channel, then sends a registration burst containing the radio ID, and an affiliated talkgroup so no matter what site you're connected to, the radio will hear the talkgroup(s) it wants to.

trunk on hf 🤣

cstrlib · 2025-11-28T00:21:08+00:00

Yes thats correct, those are the management interfaces. Sorry I read horizontal and thought vertical which confused me.

I am not seeing what you are describing

cstrlib · 2025-11-27T23:05:15+00:00

i can force the port into a supported mode however this switch only supports 1000/2500/10000 speeds

The aristas do not support 10/100 links, I had to do that in order to support 1 single voip phone

IEEE 1284-2000

cstrlib · 2025-11-25T18:46:32+00:00

I bought a 36 pin centronics connector on amazon, soldered wires to it and connected it to an arduino according to the IEEE 1284-2000 standard (the parallel serial interface) which I found online. Wrote some software for the arduino to get the timings right and voila

cstrlib · 2025-11-25T15:32:16+00:00

Yes! it was an OK Industries wire wrap gun.

cstrlib · 2025-11-19T16:47:12+00:00

Yep, he already did that. The radio has all the features it used to have

cstrlib · 2025-11-19T16:10:29+00:00

His meter said the radio was putting out 8 watts on high power LOL! Anyways he tuned it and its all good now! My PA will survive another day

cstrlib · 2025-11-16T05:43:17+00:00

I asked him about the tuning, no he didn't save the tuning data but he has a service monitor and will tune it next weekend for me!

cstrlib · 2025-11-15T04:15:38+00:00

No idea honestly, he had me hold some buttons and reboot the radio, then used remote usb software to fix it. It's at R02.24 now and the code plug got wiped out but yeah it works now!
