The Internet, Reinvented.
By Data Slayer
“Unstoppable mesh.
In this video, I build a Reticulum RNode and prove that completely different radios — LoRa and Wi-Fi — can communicate through a hardware-agnostic networking stack. Reticulum routes traffic above the radio layer, automatically bridging dissimilar frequencies, interfaces, and modulation types. I then run it over Wi-Fi HaLow Haven nodes to create a long-range, encrypted IP mesh with no traditional infrastructure. Finally, I push it further by running ATAK across the network, demonstrating a fully open-source, decentralized communication stack in action.”

The Bitcoin Veterans Summit @nprofile…m6j0 would be a great place to get your start as speaker or workshop lead.
If you are interested in ham radio, Meshtastic, Reticulum, mesh networks & emergency comms you should consider volunteering to help them out on a panel or workshop. I hear that they would prefer veterans but it’s not necessarily veterans only for these spots. So don’t let that deter you from submitting if you have something to contribute.
It was absolutely incredible what the @nprofile…64qy accomplished during the Hurricane Helene disasters response with meshtasic and ham radio. If you were involved in that project, or another like it involving radio, definitely submit. Or if you are good at explaining radio or mesh networks to normies and beginners also apply. Or if you want to talk about any other radio topics.
PS check out their video, its a banger.

Local Emergency Communications with NVIS - Let's Build an 80m/40m Dipole
By The Tech Prepper
“In this video, we'll take a look at building a simple 40m and 80m dipole for $20 dollars. Then, we'll deploy it in an NVIS (Near Vertical Incidence Skywave) configuration for local and regional communications.”
NVIS, or Near Vertical Incident Skywave, is a method of radio communication that uses shortwave frequencies to achieve effective local and regional communication. This is particularly useful in areas where line-of-sight communication is hindered by obstacles like mountains or buildings.
1. High Angle Radiation: NVIS antennas emit radio waves at high angles, typically between 75 to 90 degrees. This allows the signals to reach the ionosphere quickly and reflect back to the Earth's surface.
2. Short to Medium Range Communication: By reflecting off the ionosphere, NVIS covers a range typically from 30 to 400 miles, bridging the gap between line-of-sight VHF/UHF communication and longer-range HF skywave communication.
3. Antenna Types: Common NVIS antennas include simple dipoles, inverted V antennas, or loop antennas, often positioned only a few feet above the ground or on rooftops.
4. Ionospheric Dependence: The effectiveness of NVIS depends on the current state of the ionosphere, which is influenced by solar radiation and time of day. It's most effective at frequencies between 1.8 MHz and 10 MHz.
5. Applications: NVIS is widely used in military, emergency services, and amateur radio operations, especially in rugged terrain or during natural disasters when traditional communication methods are disrupted.
This method offers reliable, consistent coverage over a specified area, making it a vital tool in various communication scenarios.

What is Reticulum?
Reticulum is a cryptography-based networking stack for building both local and wide-area networks with readily available hardware, that can continue to operate under adverse conditions, such as extremely low bandwidth and very high latency.
Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption, forward secrecy, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable packet acknowledgements and more.
From a users perspective, Reticulum allows the creation of applications that respect and empower the autonomy and sovereignty of communities and individuals. Reticulum enables secure digital communication that cannot be subjected to outside control, manipulation or censorship.
Reticulum enables the construction of both small and potentially planetary-scale networks, without any need for hierarchical or beaureucratic structures to control or manage them, while ensuring individuals and communities full sovereignty over their own network segments.
Reticulum is a complete networking stack, and does not need IP or higher layers, although it is easy to utilise IP (with TCP or UDP) as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks. Reticulum is built directly on cryptographic principles, allowing resilience and stable functionality in open and trustless networks.
No kernel modules or drivers are required. Reticulum can run completely in userland, and will run on practically any system that runs Python 3. Reticulum runs well even on small single-board computers like the Pi Zero.

Coax & transmission line loss in radio:
When setting up a ham radio, choosing the right transmission line is all about trade-offs. Signal loss increases with both frequency and cable length. Cheaper options like RG-58 are flexible and affordable but introduce more signal loss, especially at higher frequencies. On the other hand, premium cables like LMR-400 offer much lower signal loss but come with a higher cost and reduced flexibility. The key is to balance these trade-offs by keeping cable runs short and selecting a line that fits both your operating frequency and budget.
Signal loss is measured in decibels (dB), a unit that quantifies the reduction in signal strength. A 3 dB loss cuts the signal in half, while a 10 dB loss means only 10% of the original signal remains. Every cable has trade-offs, so understanding dB helps you compare options and minimize losses for the best performance in your setup.
Meshtastic or reticulum mesh devices are transmitting and receiving in the 915 mhz range. The shorter transmission lines are preferable for this range as it lossy up at those frequencies.

A spectrum analyzer is a powerful piece of test equipment that visually displays the signal strength of different radio frequencies. For ham radio operators, it's incredibly useful for testing radios, identifying interference, and ensuring you're transmitting on the correct frequencies.
As with so many things in ham radio, spectrum analyzers have dramatically come down in price and is now more affordable than ever.
There has never been a better time to dive into ham radio than now.

For context, one of the roles of the ARRL is that functions as a lobby group for amateur radio operators in the United States. I am providing this link for informational purposes as it relates to radio spectrum that we use for mesh networks.
⚡️⚡️⚡️One of my medium to long term goals is to get enough of us into radio that when issues like this arise we can effectively get our voices with our ethos leading the conversation.

Vanity Call Signs in Ham Radio: A blank canvas to express yourself
Normally, amateur radio operators receive a randomly assigned callsign when they get licensed. However, with a vanity callsign, you can request a custom call sign as long as it fits the formatting rules specific to your nation and region.
Much like vanity license plates, vanity callsigns can be funny, clever, or even downright offensive. Amateur radio operators often get creative, choosing callsigns that play on words, include inside jokes, or reflect their personality. While many are lighthearted or witty, some have pushed boundaries to the point of being controversial or offensive. Some were only discovered to be offensive after they were issued and they had to be revoked. Some of the ones that were revoked were subsequently reissued and upon being rediscovered, they were revoked again. To see some of these look up “Hall of Fame Vanity Call Signs” on the internet.
DYK that you can use the FCC’s ULS License Search website to confirm even revoked call signs are real? See link.

HRCC interviews Hans Schwarz aka DK5JI, the author of the English translation of Rothammels Antennenbuch on the upcoming release:
Rothammel's Antenna Book (originally titled Rothammels Antennenbuch) is a highly respected and comprehensive reference book in the field of antenna theory, design, and construction. The book, written by Karl Rothammel, is considered one of the most important resources for amateur radio operators and antenna enthusiasts worldwide. It covers a wide range of topics, including the principles of antenna operation, different types of antennas, their construction, and practical applications.
For many years, Rothammel's Antenna Book was available only in German, which limited its accessibility to a broader audience. However, in recent years, for the first time, this essential manual has been translated into English. This translation allows non-German-speaking enthusiasts to access Rothammel's extensive knowledge and expertise.
The English translation of Rothammel’s Antenna Book is significant because it opens up a wealth of detailed information that was previously difficult for non-German readers to access. The manual is known for its detailed explanations, diagrams, and practical advice, making it a crucial resource for anyone involved in amateur radio, antenna design, or related fields.
With this translation, the book has gained even more recognition and use in the global amateur radio community, helping enthusiasts worldwide build and optimize their antennas with guidance from one of the most authoritative sources available.

Yes. Have you heard about @npub1jg5…6n8n satellite?
📡DYK: You can sync a full node offline & anonymously using data beamed down from Blockstream satellites in space via radio signals. 📡
What is a Blockstream Satellite Node:
A Blockstream Satellite Node broadcasts Bitcoin blockchain data via satellite, enhancing the Bitcoin network's accessibility, resilience and privacy. If you are crafty, this could be done for less than $100 fiat.
This is a great DIY project for cypherpunks. It is also a great project for using a cheap SDR.
It can also be a great way to introduce pre-coiners in your local ham radio club to bitcoin and why bitcoin nodes are important. There are a lot of very smart people in your local ham radio club that we can bring in to our side.
1. ⚡️⚡️ Satellite Transmission: Transmits Bitcoin data, reducing reliance on internet connections.
2. ⚡️⚡️ Global Access: Provides Bitcoin data access in regions with limited internet.
3. ⚡️⚡️ Network Resilience: Increases resistance to internet disruptions.
4. ⚡️⚡️ Privacy Benefits: By not relying on local ISPs, which might monitor internet traffic, satellite nodes enhance privacy and reduce surveillance risks.
5. ⚡️⚡️ Equipment Needed: Requires a satellite dish, USB satellite receiver, and a computer.
6. ⚡️⚡️ Lower Costs: Reduces bandwidth costs in areas with expensive internet.
This system promotes Bitcoin network decentralization and ensures privacy by enabling access and participation without traditional internet dependency.

GM Nostr,
Start your day out right by learning the basics about reticulum.
Reticulum is a cryptography-based networking stack for building both local and wide-area networks with readily available hardware, that can continue to operate under adverse conditions, such as extremely low bandwidth and very high latency.
Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption, forward secrecy, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable packet acknowledgements and more.
From a users perspective, Reticulum allows the creation of applications that respect and empower the autonomy and sovereignty of communities and individuals. Reticulum enables secure digital communication that cannot be subjected to outside control, manipulation or censorship.
Reticulum enables the construction of both small and potentially planetary-scale networks, without any need for hierarchical or beaureucratic structures to control or manage them, while ensuring individuals and communities full sovereignty over their own network segments.
Reticulum is a complete networking stack, and does not need IP or higher layers, although it is easy to utilise IP (with TCP or UDP) as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks. Reticulum is built directly on cryptographic principles, allowing resilience and stable functionality in open and trustless networks.
No kernel modules or drivers are required. Reticulum can run completely in userland, and will run on practically any system that runs Python 3. Reticulum runs well even on small single-board computers like the Pi Zero.

Open Source Ham Radio Project Now Available on the GBA: Nintendoes what Sega Don’t
The new open source digital radio protocol mode M17 is an exciting project that is opening up new possibilities.
👀Check out this GitHub for GBA M17 packet encoder.👀
From GitHub:
“This is a side-project created only for fun. There's no warranty that the code supplied within this repository is going to work on your device. The point of it is to show how versatile and portable libm17 (and the M17 protocol itself) is. The repeatability of it is low due to the fact that GBAs are obsolete and aren't manufactured anymore.”

1. Radio is an important decentralized freedom technology.
2. Bitcoiners and Nostriches will greatly benefit from mastering the rf domain.
3. Radio is still a ripe territory for innovation. An amateur radio license gives you an opportunity to learn about radio and provides you access to various portions of the radio spectrum to become proficient, experiment and innovate.

“GhostNet is the overarching term for a collection of communications networks set up to allow users around the world to exchange information without relying on pre-established infrastructure. Far from being just an emergency plan, GhostNet is intended to ease the transition of radio technology into everyday life. Though radio networks cannot truly replace the internet, we hope that we can replace a substantial portion of a person’s daily information requirements, and promote a culture of off-grid information sharing.”
