When conventional networks go down, or are simply not an option, teams operating in the field still need to coordinate. Akita MeshTAK is an open-source Android Tactical Assault Kit (ATAK) plugin that addresses this by bridging ATAK with Meshtastic, the low-power, decentralised radio mesh networking platform.

The plugin is developed by Akita Engineering and published under the GNU General Public License v3.0 on GitHub.

What It Does

Akita MeshTAK integrates directly into the ATAK interface, allowing field operators to share location data via Cursor on Target (CoT) messages and send text messages across a Meshtastic mesh network, all without relying on cellular, Wi-Fi, or satellite connectivity.

Device connectivity is supported over three bearers: Bluetooth Low Energy (BLE), Serial (USB), and optionally MQTT. If one bearer becomes unavailable, the plugin performs automatic failover to the next, while preserving any queued messages in the process.

Key Capabilities

Guaranteed Delivery Mailbox. Outgoing messages are queued and tracked through three states: Pending, In Flight, and Delivered. They are only marked complete when a receipt is returned from the peer device across the mesh.

Mission Assurance Dashboard. Before releasing field traffic, operators can check a dashboard that surfaces the current posture of encryption, provisioning, audit logging, and interoperability in one place.

Air-Gapped Provisioning. The provisioning workflow supports fully offline bundle generation and application. Once generated, the active secret can be staged to a connected device over a trusted local route. Transport keys are derived using PBKDF2-HMAC-SHA256 with a device and purpose salt.

Tactical Map Overlays. The plugin adds layers directly to the ATAK map, including route health, mission geofences, search sectors, and callouts for stale markers.

Mission Profiles. Operators can select from pre-configured profiles suited for Search and Rescue, Law Enforcement, Coast Guard, Military, or Private Security workflows.

No-Hardware Rehearsal Mode. A Mock Transport Mode allows the full workflow, including queued frames, peer acknowledgements, and provisioning events, to be rehearsed without a physical radio present.

Operational Themes. The UI supports Dark Ops, Light Ops, Night Red (strict monochrome), and Night Green (strict monochrome) display modes for different field environments.

Security Model

The project takes an explicit stance on security configuration. Deployment values such as BLE UUIDs, provisioning secrets, and MQTT credentials are injected at build time using environment variables via firmware/tools/load_build_config.py, rather than hardcoded in source files. Placeholder values intentionally fail production firmware builds unless a specific override flag is set or the CI rehearsal target is used.

The plugin also includes BLE and Serial command rate limiting to reduce exposure to command-flood attempts, along with audit log export and a security state reload action.

Build Requirements

The project is primarily written in Java (81.5%), with C++ (13.2%), C (3.4%), and Python (1.9%) making up the remainder. Android builds require Java 17 or 21. Java 26 is noted as unreliable with the current Gradle and Android Gradle Plugin combination at the time of writing.

Documentation

The repository includes a documentation directory with a Technical Manual, Operator’s Manual, System Specification, Security Guide, Developer Guide, and an OpenTAKServer compatibility reference. A static HTML file (documentation/ui_preview.html) provides a no-hardware visual preview of the toolbar and dashboard.

Who It’s For

The plugin targets law enforcement tactical teams, military dismounted units, search and rescue teams, first responders, and security personnel who need reliable coordination in environments where standard communications infrastructure is absent or compromised.

The project is available at github.com/AkitaEngineering/Akita-MeshTAK under the GPL-3.0 licence.

Some of you may know me from the ham-radio-lora-aprs user group. While much of my recent work focuses on LoRa, I recently realized that a specific user interface problem applies to all APRS wireless methods—not just the new stuff.

We need to talk about the user experience (UX) of APRS, and why we are letting the “mesh” crowd eat our lunch when it comes to usability.

The Original Vision: More Than Just Dots on a Map

It is a common misconception that APRS is merely a vehicle tracking system. If we look back at the words of the late, great Bob Bruninga (WB4APR), the father of the protocol, the intent was always much deeper.

As Bob said years ago on aprs.org:

“APRS is not a vehicle tracking system. It is a two-way tactical real-time digital communications system between all assets in a network sharing information about everything going on in the local area. On ham radio, this means if something is happening now, or there is information that could be valuable to you, then it should show up on your APRS radio in your mobile.”

Furthermore, the documentation defines it as a multi-user data network that is distinct from conventional packet radio because of:

1. Map integration and data display.
2. One-to-many protocols for real-time updates.
3. Generic digipeating (no prior network knowledge required).
4. A worldwide transparent internet backbone.

The Current State: Where is the “Chat”?

Mike (KC8OWL) has done an incredibly successful job reinvigorating the concept of messaging with his popular APRSThursday. Each week, 600–800 hams send messages to ANSRVR essentially to say “I’m here!”

It is amazing to see that level of participation. However, it highlights a gap: APRS, as envisioned by WB4APR, should be facilitating this kind of interaction all the time.

So, why isn’t it?

I believe the answer lies in the interface. Sending a message via traditional APRS software often feels like a technical chore rather than a seamless communication flow. There isn’t an easy, modern interface that users have come to expect in the smartphone era.

The Mesh Comparison: A Lesson in Usability

In an informal survey, I looked closely at MeshCore and Meshtastic. Both have significant user communities that include hams and non-hams alike.

The key to their success? Solid, polished apps that run on iOS and Android. They transform a phone or tablet into a sophisticated, familiar interface for a wireless packet network.

I won’t debate the pros and cons of the protocols themselves (that is a complicated discussion!). Instead, I want to highlight the User Experience differences, using MeshCore as an example.

1. The Map Experience

Maps are critical. In the MeshCore app, the map is intuitive. It shows local objects and stations clearly.

• Click-to-Interact: Clicking an icon brings up relevant details without needing to fetch data from the internet.
• Direct Action: If it’s a node, you can click to send a one-to-one message immediately.
• Remote Control: If it’s your repeater, you can log in over the air (reminiscent of the old TNC RTEXT function) for rules-compliant local control.

Crucially, this can all happen offline (provided the base map is cached).

2. Modern “Chat” Messaging

Messaging in APRS allows for one-to-one and one-to-many communication. Today, the rest of the world calls this “Chat.”

In the mesh world, the chat interface looks like WhatsApp, iMessage, or Discord. It is transparent and fluid.

• The “Public” Channel: Any operator in range can contribute.
• Ease of Flow: It encourages conversation.

Compare this to current APRS apps (like Pinpoint, YAAC, etc.). While powerful, they often lack that “pick up and play” ease of flow—especially on a mobile phone.

3. Group Channels

Imagine a more focused chat room, for example, EOC-PHX.

• Use Case: Communications specific to the Phoenix Emergency Operations Center user community.
• Management: Managed by hams at the local Red Cross.
• Filtering: While amateur radio cannot be encrypted (nothing is “secret”), the interface can restrict the view of that specific chat group to members of the EOC team, filtering out the noise of the public channel.

This concept could extend to radio clubs for meeting announcements, hamfests, or even a dedicated APRSThursday group where the app reminds you to check in!

The Feasibility Question

Some might argue that channel capacity is a bottleneck. However, with informal guidelines, it is achievable. Our local Phoenix LoRa network runs at 4.6 kbps, which is roughly 4x the capacity of a typical 1200 baud AX.25 APRS channel. I do all my APRSThursday check-ins via this LoRa network without issue.

The Hurdle: Development

It seems the biggest impediment to having an APRS app like this is the substantial effort required to develop it and get it into the “walled gardens” of the iOS App Store and Google Play Store.

However, the roadmap is there. The “mesh” community has proven that if you give people a modern, slick interface, they will use the network for exactly what Bob Bruninga envisioned: Tactical, real-time digital communication.

Is there someone out there working on this? Is it time for APRS to get a UI facelift?

Cheers and 73, Jon N7UV

Meshtastic, an open-source project that enables long-range mesh communication over LoRa radios, has gained a loyal following in the amateur radio and DIY communities. One enthusiast, Jeff Geerling, has recently documented his efforts to decode Meshtastic traffic using GNU Radio on a Raspberry Pi 5. This project showcases the power of software-defined radio (SDR) and open-source tools to visualize and understand wireless protocols.

The Goal: Portable Meshtastic Decoder

Jeff’s goal was to create a portable Meshtastic monitor using a Raspberry Pi 5, a HackRF SDR, and a 7.84″ DeskPi touchscreen mounted in a compact Rackmate TT rack. This setup would allow for real-time visualization of Meshtastic signals at events like Open Sauce, helping educate attendees about the power and accessibility of SDR.

To monitor Meshtastic communications, he centered his setup on the LongFast frequency—902.125 MHz in the U.S.—and built a GNU Radio Companion (GRC) flowgraph to decode and visualize the transmissions.

Setting Up GNU Radio on Raspberry Pi

Installation

Installing GNU Radio on Raspberry Pi OS is straightforward:

sudo apt install -y gnuradio cmake

For those using a HackRF One:

sudo apt install -y hackrf libhackrf-dev soapysdr-module-hackrf

GNU Radio Companion can be launched from the Pi menu under Programming.

If errors occur, such as ModuleNotFoundError: Cannot import gnuradio, it may be necessary to adjust your environment variables or downgrade NumPy:

pip install numpy==1.26.4

Integrating Meshtastic Support

To decode Meshtastic packets, Jeff used the Meshtastic_SDR project by Josh Conway.

Clone the project:

cd ~/Downloads
git clone https://gitlab.com/crankylinuxuser/meshtastic_sdr.git

Install dependencies:

pip3 install meshtastic --break-system-packages

Install the GNU Radio LoRa SDR plugin:

sudo apt install -y cmake
git clone https://github.com/tapparelj/gr-lora_sdr
cd gr-lora_sdr
mkdir build && cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local
sudo make install -j$(nproc)
sudo ldconfig

This installs the LoRa transceiver blocks for use in GNU Radio Companion.

Visualizing the Data

With everything installed, Jeff loaded a GRC file from the Meshtastic_SDR project:

~/Downloads/meshtastic_sdr/gnuradio scripts/RX/Meshtastic_US_allPresets.grc

Or, for RTL-SDR users with narrower bandwidth:

~/Downloads/meshtastic_sdr/gnuradio scripts/RX/Meshtastic_US_62KHz_RTLSDR.grc

He used filters and a Rational Resampler to narrow in on the LongFast channel and displayed the signal using a QT GUI Waterfall Sink. This allowed clearer visualization of signal activity over time.

To eliminate the DC spike in the center of the waterfall, you can:

1. Install gr-correctiq
2. Slightly shift the tuning off-center

Troubleshooting RX Scripts

While the GNU Radio flowgraphs worked well for visualization, decoding actual Meshtastic messages via the provided Python scripts proved problematic. Running:

cd ~/Downloads/meshtastic_sdr/python\ scripts
python3 meshtastic_gnuradio_RX.py -n 127.0.0.1 -p 20004

…resulted in repeated “OsO” messages and no usable output. Jeff filed an issue on the Meshtastic_SDR GitLab repository and is continuing to debug.

He also shared two modified GRC files—focused on a single channel to reduce CPU load:

• Meshtastic-US-LongFast.grc
• Meshtastic-US-ShortTurbo.grc

(Rename from .grc_.txt to .grc to open in GNU Radio Companion.)

Common Errors and Fixes

If you encounter errors like:

ImportError: libgnuradio-lora_sdr.so.1.0.0git: cannot open shared object file

…you may need to uninstall and reinstall the LoRa SDR plugin properly:

cd ~/Downloads/gr-lora_sdr/build
sudo make uninstall
sudo make clean
cd ..
sudo rm -rf build
# Then repeat cmake and make install steps

If your HackRF is not detected:

1. Confirm it’s visible via lsusb
2. Run:

SoapySDRUtil --probe="driver=hackrf"

If root access is needed, try sudo SoapySDRUtil ... and reboot afterwards.

Final Thoughts

Despite some hiccups decoding messages, the project demonstrates the flexibility of GNU Radio and Raspberry Pi for protocol exploration. Jeff’s build serves as a great educational tool and stepping stone for anyone interested in SDR, LoRa, or mesh networking.

For those diving in, expect a learning curve with dependencies, Python environments, and signal debugging—but the result is a powerful custom SDR monitoring setup.

Amateur radio has always been about innovation, and Hamtastic is a fine example of that spirit. Built using Python, Flask, and Node-RED, this open-source project lets you send messages from low-power Meshtastic LoRa radios to HF bands using JS8Call and FLdigi. It’s a fun, flexible integration that combines modern mesh networking with traditional amateur radio communications.

If you’re looking for a way to extend the reach of your LoRa setup into HF frequencies—or just want to tinker with some cool ham tech—Hamtastic is worth exploring.

What Hamtastic Does

At its core, Hamtastic acts as a bridge between Meshtastic (a LoRa-based mesh radio platform) and JS8Call (a weak signal digital mode for HF bands). It uses:

• Python + Flask for a lightweight web server.
• Node-RED to manage message routing and flows.
• pyserial for talking to the Meshtastic device.
• JS8Net for communicating with JS8Call.

The result: a system that listens for Meshtastic messages, processes them, and transmits them on HF. You can also build a user interface using Node-RED Dashboard if desired.

Setup Overview

You’ll need to clone the Hamtastic GitHub repo, create a Python virtual environment, and install the required libraries. A few highlights:

git clone https://github.com/TheWatchMker/Hamtastic
cd Hamtastic
python -m venv .
. bin/activate
pip install flask pyserial requests json
pip install pip@git+https://github.com/jfrancis42/js8net

For the Node-RED side, you’ll want:

npm install node-red-node-serialport node-red-dashboard node-red-contrib-http-request node-red-contrib-json

Running the Services

Hamtastic comes with two core scripts:

• MeshtasticImport.py for handling incoming messages from your LoRa device.
• Node-red-Js8call.py for pushing those messages into JS8Call.

It’s a good idea to run these as systemd services on your Raspberry Pi. Here’s a quick template for that:

[Unit]
Description=Meshtastic Integration Service
After=network.target

[Service]
ExecStart=/usr/bin/python3 /path/to/MeshtasticImport.py
WorkingDirectory=/path/to
Restart=always
User=pi

[Install]
WantedBy=multi-user.target

Enable with:

sudo systemctl enable meshtastic.service
sudo systemctl start meshtastic.service

Node-RED Flow

The project also includes a sample flow file (Node-redFlow.json) that you can import into Node-RED for testing and routing logic. It includes components like inject nodes, function processors, HTTP handlers, and debugging output—everything needed to wire together your message pipeline.

Final Thoughts

Hamtastic is a brilliant DIY solution for hams who want to bridge mesh networks and HF. It’s not plug-and-play, but it’s not overly complex either—perfect for weekend experimentation. If you’re a Raspberry Pi user with an interest in packet radio, JS8Call, or digital comms, this project is definitely worth checking out.

Special thanks to @TheWatchMker and @yNosGR for building and maintaining the project. And also credit to JS8Net by jfrancis42 for the Python-JS8Call glue.

But what exactly is ATAK? And how can it benefit the amateur radio community?

What Is ATAK?

ATAK is a geospatial mapping and situational awareness tool originally developed by the Air Force Research Laboratory (AFRL) . It runs on Android devices and provides real-time team tracking, communication, mapping, and coordination capabilities.

ATAK was initially built for military special operations forces, and later adapted for use by law enforcement, search-and-rescue teams, firefighters, and now even civilians through a version called ATAK-CIV.

At its core, ATAK gives users a powerful map-based interface to:

• See the location of other users in real time (Blue Force Tracking)
• Share points, routes, and geofences
• Chat over various networks
• Use offline maps (MBTiles, GeoTIFF, etc.)
• Connect to radios, drones, sensors, and more

Military Origins and Field-Proven Capabilities

ATAK was born out of the need for situational dominance in high-risk tactical environments. Since its inception, it has seen extensive use in:

• Special Forces operations
• Coordinated drone strikes and ISR (Intelligence, Surveillance, Reconnaissance)
• Disaster relief missions and humanitarian assistance

The military-grade versions of ATAK allow seamless communication between air and ground units, display live video feeds from UAVs, and integrate with secure tactical radios like Harris and Thales. In these missions, ATAK was crucial in reducing friendly fire, increasing operational efficiency, and enhancing coordination across distributed teams.

How Amateur Radio Can Leverage ATAK

The civilian version of ATAK (ATAK-CIV) is publicly available and, while it doesn’t include all the secure military features, it retains the robust mapping and coordination tools—making it a great fit for amateur radio use, especially for:

1. Emergency Communications (EmComm)

During disasters like floods, forest fires, or earthquakes, hams often assist in relaying messages, tracking resources, and supporting relief teams. ATAK can:

• Display real-time positions of operators
• Mark critical locations like shelters, aid stations, or damaged infrastructure
• Overlay live weather or fire maps for situational context
• Enable chat via connected data radios or LTE

2. Search and Rescue (SAR) Operations

In SAR scenarios, coordination and tracking are everything. By combining APRS or Meshtastic with ATAK, you can:

• Track all search team members
• Share maps and grid search sectors
• Use GPS navigation tools with offline maps
• Share findings instantly with the base team

3. Field Day and Group Activities

ATAK can also enhance casual and educational activities:

• Show everyone’s location at the site
• Coordinate hiking and portable radio stations (SOTA/POTA)
• Share propagation conditions or weather overlays
• Mark antenna layouts or signal coverage maps

4. Tactical Exercises or Field Training

For clubs simulating tactical communication or prepping for EmComm, ATAK offers a real-world, interactive platform:

• Run map-based scenarios
• Share check-ins and digital traffic via radio-linked messaging
• Log positional and message data

Integrating ATAK with Ham Radio Tools

Here’s where it gets interesting: ATAK supports plugins, allowing custom integrations. Some practical ways for hams to connect ATAK to their gear:

• APRS via TCP/IP or KISS TNCs: Share your APRS location directly on ATAK maps.
• Meshtastic Integration: Connect to LoRa-based mesh networks for off-grid communication.
• RTL-SDR: Overlay live signal detection and waterfall data.
• DIY plugins: If you’re a developer, you can write custom plugins to integrate your radio or weather station.

With ATAK, your smartphone or tablet becomes a tactical command tool, fully capable of mapping, communicating, and navigating in complex environments.

Final Thoughts

While ATAK’s military roots are clear, its evolution into a civilian and amateur radio tool is exciting. For those of us in the ham radio world—whether you’re into SOTA, EmComm, SAR, or digital modes—ATAK offers a new level of operational awareness, visualization, and efficiency.

As with all tools, it’s only as effective as the team using it. Train with it. Experiment with integrations. And when the time comes—be it a field exercise or a real emergency—you’ll have one of the most powerful tactical apps right in your pocket.

In a world where communication infrastructure can be unreliable—or even unavailable—projects like Meshtastic are pushing the boundaries of decentralized, off-grid messaging. Built around low-power LoRa radios, Meshtastic provides peer-to-peer mesh networking for text-based communication without the need for cellular, Wi-Fi, or satellite connectivity.

But how does it actually work under the hood? This article offers a technical overview of the Meshtastic architecture, protocols, and hardware that make it possible.

What Is Meshtastic?

Meshtastic is an open-source firmware and app ecosystem that enables users to send encrypted text messages and telemetry over a self-healing, long-range mesh network using inexpensive LoRa radios. It is especially useful for:

• Outdoor adventures (hiking, skiing, biking)
• Emergency preparedness
• Decentralized communities
• Off-grid events (e.g., festivals, camps)

The Core Technology Stack

Meshtastic is composed of the following core components:

1. LoRa Radios

Meshtastic leverages Semtech’s LoRa transceivers (e.g., SX1262, SX1276), typically housed on modules like:

• TTGO T-Beam
• Heltec Wireless Stick
• RAK Wireless boards

LoRa (short for Long Range) is a physical layer radio modulation that operates in unlicensed ISM bands (e.g., 433 MHz, 868 MHz, 915 MHz). Its low data rate (typically < 300 kbps) is offset by its ability to reach distances of 2–10 km in open terrain with extremely low power consumption.

2. ESP32 Microcontroller

Most Meshtastic nodes are powered by the ESP32 platform, which provides:

• Wi-Fi/Bluetooth capability for local interfaces
• GPIO for peripherals (GPS, OLED)
• Adequate processing power for packet handling and encryption

3. Mesh Networking Protocol

At the heart of Meshtastic is its custom lightweight mesh protocol, designed to handle:

• Packet forwarding across multiple nodes (multi-hop)
• Message deduplication and timestamping
• Path discovery and optimization (basic flooding with filtering)
• Optional routing metadata for controlled message propagation

Encryption and Security

Meshtastic uses AES-256 encryption by default for all messages, ensuring that only authorized nodes in the same channel (with the same encryption key) can decrypt communications. Each mesh channel is defined by:

• Channel Name (hash seed)
• PSK (Pre-Shared Key) used for symmetric encryption

Key exchange is manual (or QR-based) to avoid over-the-air compromise.

Message Types

Meshtastic supports various message types, including:

• Text Messages (with delivery confirmation)
• Position Reports (GPS-based)
• Telemetry (battery, signal strength, uptime)
• Node Metadata (nickname, hardware info)
• Configuration Commands (e.g., set channel, transmit power)

Each packet is encoded using protobuf to reduce payload size and increase processing efficiency.

Interfaces: How Users Interact

1. Meshtastic App

Available for Android, iOS, and desktop, the app connects via Bluetooth or serial USB to a node. It provides:

• Chat-style messaging
• Channel settings
• Device diagnostics
• Firmware updates

2. Command Line Interface (CLI)

For power users, Meshtastic offers a Python-based CLI:

meshtastic --info
meshtastic --set is_router true

3. MQTT Gateway

With Wi-Fi enabled, a node can act as an MQTT bridge to a central server (e.g., Home Assistant, Mosquitto) for cloud-based communication and automation.

Power Consumption and Deployment

Meshtastic is optimized for low-power operation, allowing devices to run for days or even weeks on a single 18650 battery. Power-saving features include:

• Deep sleep mode between transmissions
• Adaptive transmission interval
• Minimal background processing

Users can deploy nodes as:

• Portable handheld devices
• Fixed solar-powered repeaters
• Backpack-mounted trackers

Community and Ecosystem

Meshtastic is maintained by a passionate open-source community and continues to evolve rapidly. Popular ecosystem projects include:

• Meshtastic-web: Web-based interface for configuring nodes
• Meshmap: Real-time network topology visualization
• APRSTastic: Bridging Meshtastic to APRS networks

Development is active on GitHub, and community support thrives on Discord and forums.

Limitations

Despite its versatility, Meshtastic has constraints:

• Not suitable for voice or real-time video
• Regulatory limits on duty cycle in some LoRa bands
• Message latency increases with network congestion
• No IP-level networking (not designed for TCP/UDP)

Final Thoughts

Meshtastic represents a powerful and elegant solution for decentralized, off-grid communication. By blending the reliability of LoRa, the accessibility of ESP32 hardware, and the flexibility of mesh protocols, it opens up a world of possibilities—from backcountry expeditions to disaster recovery.

Whether you’re an amateur radio enthusiast, an emergency planner, or a curious maker, Meshtastic is a fascinating project to explore—and possibly contribute to.

When you dive into the world of open-source software, you’ll eventually come across different licenses—each one spelling out what you can and can’t do with someone else’s code. One of the most well-known and widely used is the GNU General Public License version 3, or simply GPLv3.

But legal documents are hard to read. So let’s break it down in plain language.

What Is GPLv3, Really?

At its heart, GPLv3 is a license that protects freedom—your freedom to use, modify, share, and improve software.

It was created by the Free Software Foundation (FSF), an organization that believes software should serve its users, not the other way around.

So GPLv3 isn’t about restricting you—it’s about making sure that everyone has equal rights to software.

What Can You Do with GPLv3 Software?

You’re allowed to do a lot, including:

1. Use it however you want
   • Personal, commercial, educational… anything goes.
2. Modify it
   • You can change the code to suit your needs.
3. Distribute it
   • You can share the software with others, either in its original form or after you’ve made changes.
4. Charge money for it
   • Yup. You can sell GPLv3 software if you want—but you have to follow the rules (more below).

But There Are Some Rules…

GPLv3 is often called a “copyleft” license, meaning that it flips traditional copyright on its head. Instead of restricting copying, it requires sharing, with the same freedoms.

If you modify and distribute GPLv3 software (especially to the public), you must:

1. Also, share the source code
   • If you give someone a binary (compiled version), you must also give them the source code, or offer it.
2. Keep the license intact
   • Your users must get the same rights you got. You can’t restrict them from modifying or sharing.
3. State your changes
   • Be clear about what you changed and who did it.
4. Do not lock the software down
   • No DRM tricks. You can’t stop users from modifying the software you distribute.

What About “Tivoization”?

Back in the day, companies like TiVo started using GPL software in their products, but added hardware restrictions that blocked users from running modified versions. That didn’t sit well with the FSF.

So GPLv3 fixed that loophole. If you distribute GPLv3 software in a product, you must give users everything they need to actually use modified versions—including keys or documentation to bypass any restrictions.

Can I Use GPLv3 in My Business?

Yes—but be careful.

• If you only use GPLv3 software internally (e.g., running it on your servers), you’re fine.
• But if you distribute it (e.g., ship devices, sell software), you must comply with all the sharing requirements.
• If you mix GPLv3 code with proprietary code, things get tricky. You may be forced to open-source your code if it’s tightly integrated.

So, GPLv3 is great for collaboration, but it’s not ideal if your business model depends on keeping your source code private.

Why Do People Choose GPLv3?

People and projects choose GPLv3 because they want to:

• Promote freedom and community-driven development
• Prevent their code from being locked down or taken private
• Ensure that everyone who benefits from their work can also contribute back

Think of it like a software version of “take a penny, leave a penny.”

Quick FAQ

Q: Can I make money with GPLv3 software?
Yes! You can sell it, offer services, or build products with it—just follow the rules.

Q: Do I have to share my code if I just use GPLv3 software privately?
No. The license only kicks in if you distribute the software or a modified version.

Q: Can I use GPLv3 code in my app and keep my code closed-source?
Usually no. If the GPL code and your code are deeply connected, your code must also be GPL.

What GPLv3 Means

If you’re using, modifying, or even building something, GPLv3 grants you:

The freedom to use the software however you want
The right to modify the code
The ability to distribute original or modified versions
The option to sell

But it also requires you to:

Share the source code of any modified version you distribute
Keep the software under the same license (GPLv3)
Allow users to modify the software themselves (no locking down with DRM or proprietary hardware)

Final Thoughts

The GPLv3 is not about control—it’s about freedom. It’s designed to ensure that no one can take a shared resource and turn it into a walled garden. It encourages innovation, collaboration, and fairness. If you’re okay with giving back to the community and playing by open rules, GPLv3 is a powerful tool for building great software together.

Using software licensed under GPLv3 gives you the freedom to study, modify, and distribute it, but it doesn’t give you ownership over the original work. While you’re free to add your features or improvements and even copyright those specific changes, the entire combined project must still follow the rules of the GPLv3 license. That means you cannot lock it down, claim it as entirely your own, or prevent others from using it under the same terms. GPLv3 is about sharing knowledge, not claiming exclusive rights over a community-driven effort.

Enter the NAS — Network Attached Storage — a powerful and often overlooked tool for modern amateur radio operators. Whether you’re a casual hobbyist or a serious station manager, a NAS can simplify and secure your digital life in the shack.

Let’s explore how NAS systems can benefit amateur radio operators, practical use cases, and some guidance to help you set one up.

What is a NAS?

A NAS is a dedicated device or server connected to your local network that stores data and provides services like file sharing, media streaming, backups, and more. Think of it as your personal cloud, available on your LAN (and remotely if you allow it).

Open-source NAS systems like TrueNAS, OpenMediaVault, Rockstor, and XigmaNAS make it easy and affordable for hams to build one using spare hardware or a Raspberry Pi.

Why Hams Should Consider a NAS

Here are several ways a NAS can become a central part of your shack:

1. Logbook and Data Backup

Store all your digital logbooks (e.g., N1MM, CQRLOG, Ham Radio Deluxe, Fldigi) in one place and access them from multiple devices.

• Automatically back up logs from your Raspberry Pi or Windows machine.
• Share your logbook with your contesting team on the same LAN.
• Keep a version history in case of accidental deletion.

2. SDR Recordings & Waterfalls Archive

Running SDR receivers like SDRplay, HackRF, or RTL-SDR? Those I/Q recordings and spectrogram images can take up a lot of space. A NAS lets you:

• Store massive SDR data files securely.
• Host them for playback or offline analysis.
• Use ZFS/Btrfs snapshots to prevent data corruption.

3. Web Server for Shack Tools

Host useful ham tools like:

• Local callsign lookup database
• DX cluster web interface
• OpenWebRX or KiwiSDR server
• Static wiki/documentation for station SOPs

A NAS with Docker support can run these tools as services—without tying up your main shack PC.

4. Shared Resources and Scripts

Many hams use scripting (Bash, Python, Node-RED) for automating things like antenna switching, remote rig control, or APRS messaging. Store all your scripts and station configs in one place.

Bonus:

• Sync with Git for version control.
• Share with your team during field day or emergency comms ops.

5. APRS and Meshtastic Gateway Backups

Running APRS I-Gates, Meshtastic bridges, or Direwolf/KISS TNC setups? Store:

• Config files (JSON, ini, conf)
• Logs of packet traffic
• Diagnostic captures (tcpdump, AX.25 monitoring)

Keep everything ready for instant restore if your SBC or microSD card fails.

6. SSTV and Digital Mode Archiving

Store and organize:

• SSTV images
• JS8Call messages
• FT8/FT4 decoded logs
• Signal reports and waterfall screenshots

Add tags or naming conventions for contests, satellite passes, or unusual propagation events.

7. Emergency Communications (EmComm)

Prepare for EmComm deployments by:

• Preloading maps, ICS forms, and software installers.
• Hosting offline resources (e.g., Wikipedia snapshot, repeater directory).
• Synchronizing field logs to your home NAS when the network comes online.

Choosing the Right NAS Setup

Pro tip: Use a UPS (Uninterruptible Power Supply) with your NAS to avoid data corruption during power outages—especially during storms or field deployments.

Real-World Ham Use: Example Scenario

Imagine this:

• You’re operating remote HF from your home, using a Raspberry Pi to control a rig via Hamlib.
• The Pi is running WSJT-X for FT8.
• Logs are automatically pushed to your NAS.
• You’ve configured your NAS to back up these logs to a cloud provider weekly.
• You also run Node-RED dashboards on the NAS to monitor temperature, power, and SWR sensors remotely.

This setup gives you flexibility, reliability, and peace of mind—all using open-source tools and amateur radio creativity.

Getting Started

1. Reuse an old PC or get a Raspberry Pi 4 with a USB drive.
2. Choose your NAS OS (TrueNAS, OpenMediaVault, etc.).
3. Connect it to your local network via Ethernet.
4. Enable services like SMB/NFS, Docker, and snapshots.
5. Start saving, sharing, and serving your ham shack data like a pro.

Final Thoughts

In 2025, the amateur radio shack is no longer just radios and antennas—it’s also data, software, and services. By adding a NAS to your setup, you gain control, resilience, and smarter station management.

Whether you’re a contester, experimenter, satellite operator, or EmComm volunteer, a NAS is an investment that pays off in convenience, security, and scalability.

Stay curious, stay connected, and happy experimenting!

In an age where reliable communication is mission-critical—whether in the battlefield, disaster zones, or even off-grid adventures—mesh radios are becoming increasingly essential. Unlike traditional radio systems that depend on centralized infrastructure like towers or repeaters, mesh radio systems form decentralized, self-healing networks that adapt dynamically to changing conditions.

But what exactly is a mesh radio? How does it work, and who uses it?

What Is a Mesh Radio Network?

A mesh radio network is a type of wireless communication system where each radio device (or node) connects directly, dynamically, and non-hierarchically with other nodes in the network. Instead of relaying messages through a central hub, each device can send, receive, and forward data to other nodes.

Key Characteristics:

• Self-healing: If one node fails or moves out of range, the network reroutes the data automatically.
• Scalable: The more nodes, the stronger the network becomes.
• Decentralized: No reliance on traditional infrastructure.
• Ad-hoc: Can be deployed rapidly in the field.

How It Works

Imagine each node as a two-way radio with built-in intelligence. When a message is sent, it travels from one node to the next until it reaches its destination. If a direct link isn’t available, the data “hops” across multiple radios. This process is known as multi-hop routing.

Protocols like B.A.T.M.A.N. (Better Approach To Mobile Adhoc Networking) or proprietary algorithms in commercial systems ensure that the network selects the most efficient path for communication.

Mesh Radio in Military Use

Modern armed forces require resilient and secure communications in complex and hostile environments. Mesh radios allow soldiers, vehicles, drones, and command posts to stay connected even when GPS is jammed or cellular infrastructure is absent.

Example Use Cases:

• Soldier-to-soldier comms in dense urban terrain
• Vehicular convoys maintaining networked awareness across kilometers
• Unmanned systems (UAVs and UGVs) relaying intel to command units
• Joint tactical operations with real-time positioning and voice/data updates

Products: TrellisWare TW-400, Persistent Systems Wave Relay, Silvus StreamCaster

First Responders & Emergency Services

During disasters like earthquakes, floods, or large-scale fires, conventional communication systems often fail. Mesh radios allow police, paramedics, firefighters, and SAR teams to maintain contact.

Key Benefits:

• Rapid deployment without infrastructure
• Inter-agency communication with mesh bridges
• GPS tracking and data sharing over mobile mesh nodes

In Malaysia, Civil Defence (APM) have tested and used mesh-capable radios during exercises and disaster drills, especially in remote areas or post-flood zones.

Amateur Radio & Civilian Applications

Thanks to open-source projects and commercial offerings, mesh networking is also accessible to radio amateurs, off-grid adventurers, and community groups.

Amateur Radio (Ham):

• AREDN (Amateur Radio Emergency Data Network): Uses modified Wi-Fi gear on ham bands to create IP-based mesh networks.
• High-speed mesh links between repeaters, clubs, or shelters.
• Message relays and APRS integration over mesh networks.

Civilian / Recreational:

• Meshtastic: An open-source, low-power mesh radio system using LoRa (Long Range) for messaging and GPS sharing.
• Used by hikers, bikers, and preppers in off-grid areas.
• No cell signal? No problem—your group stays connected via Meshtastic nodes in their backpacks or vehicles.

Real-World Example: Meshtastic in Malaysia

In Malaysia, Meshtastic is gaining popularity among radio hobbyists and rural explorers. With nodes running on ESP32-based boards and LoRa modules.

Thanks to its GPS and text-messaging features, it also offers a unique integration with APRS for location-based tracking over amateur radio.

Final Thoughts

Mesh radio systems are transforming how we think about wireless communication—offering redundancy, flexibility, and autonomy. Whether you’re a soldier in a contested zone, a firefighter navigating a collapsed building, or a ham radio enthusiast testing a hilltop node, mesh networking gives you the power to communicate, even when everything else fails.
