Ham Radio / Off-grid communication

[TV's Adam West]

LOOK AT THE PICTURE!!! See the skull, the part of bone removed, the "master-race" Frankenstein radio controls, the Brain-thoughts Broadcasting Radio, the Eyesight Television, the Frankenstein Earphone Radio, the Threshold Brainwash Radio, the latest new skull reforming to contain ALL Frankenstein Controls, even in THIN skulls of WHITE PEDIGREE MALES! Visible Frankenstein controls! The synthetic nerve-radio directional antennae loop! Make copies for yourself! There is NO ESCAPE from this worst gangster police state, using ALL of the deadly gangster Frankenstein controls!

Absolutely incredible, good work man!

 

[Detective Carey]

Hell yeah.

 

[gildersleeve]

Now this is the skill I love seeing. Great work! I wish I had the equipment to try it out. Can you reccomend a minimal viable setup to do so?

 

[Pat Fried Rice]

I wanna learn HAM radio just for this. This seems absolutely wicked

I just want to say, at this time, as a license holder, you absolutely should learn the basics of ham radio. If you can find a local radio club, classes are often very low price or even free. When I took my certification course for my technician license, they literally went over everything we needed to know, then we got the test for $20. As long as you can do basic reading and memory retention, you should be able to walk out of one of those type of sessions with your license.

HAM books on Amazon are also relatively cheap if you want to dig deeper into the hardware, and specific physics of how radio in general, and ham specifically operates. It can never hurt to have a small backpack unit that can put you in contact with people and monitor NOAA.

What sort of gear does a retard (me) who knows nothing about radios need to use this? This is incredibly cool.

To make a long story short, you need basic braincell (You can follow instructions) , and basic retention (I can remember words I read). You can contact your local radio club to get their expertise (My advice, learned so much from those geezers.) , or you can buy a Baofeng handheld and try yourself. Always stay within local, state, and federal guidelines when using any radio, and make sure to get your license before transmitting. the FCC does not fuck around much.

*Edit: Had this typed up outside and forgot to paste. Always check Amazon for discount HAM books. While it might seem like they're out of date, the basics remain. Repeater books are a must.*

Most importantly,

RESEARCH. YOUR. SHIT.

I've developed a frontend for accessing the KiwiFarms over HF radio and other low-bitrate networking devices.

For HF radio links, it uses a software modem that's a wrapper around the codec2 raw data modes with an added ARQ and beaconing layer [under active development].

The Reticulum Network Stack provides full end to end encryption, perfect forward secrecy and handles the networking layer.
The Nomad Net client is used to serve page requests. Selenium and beautifulsoup4 is used to render the site's content into a lightweight markdown format. While the node serving page requests does need a standard Internet connection to access the site, it's more than possible to host content without it.


The full source code for both the HF software modem and KF node will be published soon.

This is so violently based that words escape me. Semper Fi.

that's giving me oldschool BBS vibes.

It's times like this, when I see the sheer concentrated power of autism, that I realize: I'm not autistic, I'm just retarded.

 

[Pierre D'Olnique]

To me this is magic of a degree comparable to showing fire to a caveman. Is it like teletext? Looks like teletext.

This has such a wonderful old /k/ innawoods atmosphere to it. You went above and beyond just doing a tech demo, this has a great setting.

Finally I can secretly post my new world order propaganda which the feds will spend hundreds of man hours to crack into only to find out it's a navy seal copy pasta with the occasional nigger word sprinkled in.

You are a legend.

All you need is a radio, soundcard interface, and a computer. Look up how build a PSK31 setup.

Btw if I understand correctly, the system made by 888Flux uses traffic encryption, and traffic encryption is banned on HAM bands pretty much everywhere.
I personally don't care about regulations, but if this thing is to be run legally on HAM bands, traffic should be in cleartext and cryptography used only for authentication.

 

[hog cranking frog]

Can't wait to see the source code drop want to try this out innawoods too.

I wrote some short guides in this thread that might help, you can find Part 1 and Part 2 here

This setup uses the HF spectrum, specifically NVIS propagation (PreserveTube) for beyond line of sight regional communications within a range of 0 to 650 kilometers (0 to 400 miles). All that is needed on both ends of the setup is an antenna, a computer, and a radio.

Most HF antennas are just a length of wire cut to a specific wavelength for the frequency you are operating on, it's very simple and a setup like this gives you true peer to peer connectivity with no repeaters or intermediaries.

The antenna in the demo video was a 49:1 end fed half wave attached to an arborist weight tossed in a tree. Specifically it is a "Spooltenna" brand one, but you can easily DIY one yourself. (Someone made one earlier in the thread a couple pages back)

HF enables communication beyond line of sight with no infrastructure. NVIS propagation has many advantages because it allows for less volatile band conditions, higher data rates, and because the power is uniform under a received radius it is highly resistant to radio direction finding. It's also much easier to deploy because you can have the antenna wire as low as a foot off the ground.



The radio I used out in the field was a a Xiegu X6100. One cool part about this rig is that it can actually run Armbian on the radio itself, and in future experiments I am testing out whether or not it's possible to run both the modem software, NomadNet, and everything self-contained

Holy shit, this thread got popular fast. I don't keep up with MATI, did Jersh highlight the Kiwinode there?

Fun fact: this thread was what actually got me interested in the hobby and licensed. Always amazing to see more people enter the hobby because of Flux's work, incredible job man. Just a word of note for those looking to get licensed to make this work: receiving does not require a license, but legally transmitting data does. In the US, there are three different tiers of amateur radio licenses you can test for, with each tier getting access to a wider range of frequencies: Technician, General, and Extra. Transmitting on most of HF for this purpose requires a General class license, with the exception of Technicians having a small sliver of voice-only communications between 28.300 and 28.500 MHz in the US.


Every test is multiple-choice and the question pool is openly available for studying/memorization. I suggest using HamStudy to learn the questions on the Technician and General tests, they provide an explanation for the answer to every question. W4EEY's study videos are also very good resources. Good luck, my fellow sneeders.

Ham radio is like CB radio with the fun removed.
