Off The Grid​

NC PACKET depends on 100% Amateur Radio Operator controlled infrastructure.
No Internet required. No Internet desired.

Our network can't be disrupted by short term or long term disruptions in the CATV, Cellular, or other Internet systems.


 
Is a Kantronics KPC-3 Plus a suitable TNC for something like this, or do you have to build the one specified in the hardware link on the ncpacket.net site?

I just happen to have the KPC-3 in a box, already setup to plug into a 2m radio which is also in the box.

The ncpacket links get engineered so they are reliable, and, they are all on different and coordinated frequencies so there is no hidden transmitter syndrome.
Way better than the old days.

I didn't really get that your response was an answer to Jayne's question about the Kantronics TNC.
Your response seemed to be canned for another question not asked.

There isn't one 'fixed' answer to the question.

To get to a 'yes' or a 'no' to the question means that you'd need to know who you were connecting to on the other end and what gear they are running and what band and frequency gets used to build out that particular link and whether or not it can support a higher bitrate or is limited to the Kantronics speed.

We see a LOT of general inquiries here on CFF about amateur radio communications. Firearms users are often interested to learn more about what can be accomplished for various reasons of preparedness. Many wish to be independent of commercially operated infrastructure, as these can easily disappear for all the possible reasons you might think of.

NC PACKET is simply a local implementation of a TARPN: terrestrial amateur radio packet network.

All links in a terrestrial amateur radio packet network (TARPN) are point to point and engineered (managed frequencies, power levels, signal-to-noise levels, fade margins, modulation types, beamwidth, and bandwidth). Definitely NOT like the old packet radio from the 1980s, which died a slow death because people used the technology incorrectly, or APRS, which cannot correctly scale or ever be reliable.

Each node (the setup at your home, often consisting of multiple radios, controllers, and antennas) could be capable of hosting not only your own communications but all the rest on your 'path' so there is no central infrastructure.

The network nodes are generally made of extremely low cost parts that are either surplus radio gear or purpose-made elements that are available at the cost of the parts. Power supplies are often repurposed from other uses. Many use custom equipment enclosures made by several of the participants. All code is open. Each node operator is a hands-on owner, fully capable of all their own maintenance and improvements and expansion.

The goals go beyond simple communications to include learning, resiliency, and independence. These are themes that definitely map to many of the desires of the firearm owning community.

There are multiple weekly nets, on UHF and on 75m, to discuss these topics, as well as a groups.io reflector. All you have to have is any amateur radio license, a place to operate a node within link ability of at least one other, a sincere desire, and a willingness to learn hands-on.

My posting here is simply to make the presence of this system more well known. It's up to the participant to learn more and decide whether to become part of the network.
 
TL;DR
@Jayne you appear to be in your own ;)
The answer is "maybe"? Pfft

It does appear that it's 'maybe' but I think I understand why. The network is all point to point, so if my end and someone else's end can agree to talk whatever the kantronics box can do, it can work.

It's less like UUCP via dialup and more like UUCP via dialup, smoke signals, carrier pigeon or whatever the two nodes agree to use as the protocol. I think.
 
@Jayne
Seems built link-by-link compatibility without regard for link-to-other-link, so you can lose your connection to the network if your compatible link goes down - especially if you are a far end-point.

For various archaic reasons, I've not used Packet in nearly a decade - which was on MARS in CLT.

I will stick with VARA modem, VarAC and Winlink. Recently of interest is Meshtastic.

NCPACKET is built by hobbyists with hobbyist budgets. It's not going to be built with redundancy first. Minimum cost barrier to entry is an important consideration. As the software is improved (some by members, some imported) the capabilities of taking advantage of redundancy will improve. At this time the CHAT software doesn't deal well with existing redundancy. We're working on a fail-safe chat system. Much of this is going to have to be homegrown.

We're the only hobbyist built network that is compatible with home installation, and flat forests, that I know of and which is also fast enough to maintain a full-time-up state-wide real-time text chat. LORA and WiFI are interesting but not particularly long-range when plowing through dense 100' tall trees. 25watt 2m links with tree-hung Comet GP-3 antennas are good for 5 to 20 miles in central NC.

A Kantronic TNC (retail $250 maximum purchase 10 units) works just fine for doing the kind of stuff NCPACKET is doing, but the TARPN NinoTNC is 10x the performance for 1/5th the cost, and we can buy them by the 100 for our network if we need to. We've identified radios that can do 9600 baud with our NinoTNC. Most of the NCPACKET network is running at 4800 or 9600 and almost all of it is 2400 baud or better. With text chat, that means less than half a second per link latency and the ability to support a new line of chat text every few seconds.

The NCPACKET mission is to build a great big network that is fun to play with. It has important side effects and potential applications.
Most packet networks can only handle one human participant at a time. Most packet networks would fail completely if they were actually as popular as they'd like to be. The TARPN architecture supports surviving success.
Unlike VarAC, packet of the 90s, WinLink, the systems are full-time-up and everybody is a network builder. Most of the packet systems have a builder and a user. The user is not running the same hardware, learning the same lessons, or capable of rebuilding or duplicating the network if times got rough. A TARPN user is a TARPN builder and learns all the lessons needed to construct their own networks, either in parallel to the existing effort, in advance of the existing effort, away from the existing effort, or after the existing effort is wiped out by some scenario.

We're not selling anything for profit. We're trying to do our part in boosting ham radio which also educates, and connects our countrymen. NCPACKET is a kick to play with.

What happened to that NCPacket screed by the new guy?
It was a bit long as a first post by a brand new member advertising his pet project, but not necessarily needing to be deleted.

He doesn't have enough history here to be able to post, yet. Oddly, it went 'live' then it appears to have been manually moderated.
The new member didn't know of the CFF policies. (They aren't intuitively obvious, to be fair.)
