DragonOS FocalX Transmit and Receive Meshtastic w/ SDR (hackRF, Airspy R2, R36)

"In this video, we take a deeper dive into the setup and usage of the meshtastic_SDR repository, which now enables the transmission and reception of Meshtastic using Software Defined Radios (SDRs). Recent updates have made this possible by partially leveraging GNU Radio flow graphs for both RX (receive) and TX (transmit), and integrating Python scripts that connect to ZMQ sources for message input and ZMQ outputs for message decoding.

I demonstrate the setup using a HackRF for the transmit side and an Airspy R2 for receiving. We also verify the results of TX and RX using a standard Meshtastic receiver to ensure accurate performance.

Unboxing Elecrow ThinkNode M1 & M2 | #Meshtastic Setup, Field Test, Review & Off-Grid Comms Breakdown
https://rumble.com/v6v1uk1

In this video, I take you deep into the world of off-grid communication as I unbox and test two brand-new devices from Elecrow: the ThinkNode M1 and ThinkNode M2. These tools come pre-installed with Meshtastic firmware and are built for encrypted, decentralized communication — no SIM card, no Wi-Fi, and no cell towers required. Whether you’re prepping for a blackout, building a resilient mesh network, or just exploring survival tech, this video is packed with everything you need to know.

We start with a full unboxing of both devices, breaking down what makes each unique. The ThinkNode M1 is powered by the nRF52840 chip and includes a GPS module for location tracking, a 1.54” sunlight-readable EPD screen, and a 1200mAh battery built to last over 48 hours. It’s rugged, outdoor-ready, and ideal for emergency kits or remote travel. In contrast, the ThinkNode M2 is lighter, smaller, and powered by the ESP32-S3 chip. It includes a 1.3” OLED display, Bluetooth support, a 1000mAh battery, and is better suited for modular integration or stealthy builds.

After the unboxing, I walk you through a step-by-step setup of each device using the Meshtastic mobile app. I show you how to configure them, pair with Bluetooth, and get your private mesh network up and running in minutes. From there, I run live tests to see how each device performs in real-world conditions and compare their features, form factor, and best use cases.

If you’re interested in off-grid privacy tools, these are two of the most beginner-friendly and capable devices out there right now. I also include a breakdown of which device might be better depending on your needs—whether you’re building a neighborhood mesh or planning for emergency scenarios.

These tools are more than tech — they represent freedom. In a world where networks can go dark and censorship can silence, devices like these keep people connected, informed, and in control. With Meshtastic and LoRa, you are the signal. You are the network. And it’s all open source.

If you found this helpful, drop a comment, like the video, and subscribe for more content on off-grid tech, cybersecurity gadgets, and digital autonomy. Let me know which one you’d trust in your blackout bag — the rugged M1 or the sleek, portable M2.

LORA: SOBERANÍA EN LAS COMUNICACIONES

Nuestro amigo y compañero Antares, nos presenta el sistema #LORA: técnica de comunicación física por radio (a través de una onda electromagnética) que utiliza bandas de radiofrecuencia de subgigahercios sin licencia EU868 (863–870/873 MHz) en Europa, AU915/AS923-1 (915–928 MHz) en América del Sur; US915 (902–928 MHz) en América del Norte, y 2,4 GHz en todo el mundo.
Con aparatos muy económicos podemos mandar mensajes encriptados entre usuarios con mucha facilidad.

LORA: SOVEREIGNTY IN COMMUNICATIONS

Our friend and colleague Antares presents the #LORA system: a physical radio communication technique (via an electromagnetic wave) that uses the unlicensed subgigahertz radio frequency bands EU868 (863–870/873 MHz) in Europe, AU915/AS923-1 (915–928 MHz) in South America; US915 (902–928 MHz) in North America, and 2.4 GHz worldwide.
With very inexpensive devices, we can easily send encrypted messages between users.
