When severe weather strikes or an unexpected emergency unfolds, communication becomes the most important tool you have. For the WSHE379 GMRS community, staying connected can mean the difference between confusion and coordination, isolation and assistance. While GMRS is an excellent primary system for family and community communication, having more than one type of radio available is a critical part of emergency preparedness. One of the most valuable backup options is Citizens Band (CB) radio.

Why Redundant Communication Matters

Emergencies rarely unfold in predictable ways. Power outages, damaged infrastructure, overloaded cellular networks, and even terrain can all disrupt communication. That’s why experienced emergency communicators rely on redundancy—having multiple systems that can operate independently of each other.

If one system fails, another can take its place.

In a severe weather event, for example:

• Cell networks may become congested or fail.
• Internet-based communications can go offline.
• Repeaters used by GMRS or amateur radio systems may lose power.

Having a backup radio service that operates independently ensures you still have a way to communicate.

What Is CB Radio?

CB (Citizens Band) radio is a short-range radio service that operates on 40 channels in the 27 MHz band. Unlike GMRS, CB does not require a license in the United States and is widely used by truck drivers, travelers, off-road groups, and rural communities.

CB radios have been a staple of emergency communication for decades because they are:

• Simple to use
• Widely available
• Independent of infrastructure
• Operable during power outages with battery power

Even when other systems are unavailable, CB radios can often still reach nearby drivers, travelers, and residents who may be monitoring channels.

Why CB Makes a Good Backup to GMRS

While GMRS provides clearer audio, repeaters, and more structured community communication, CB offers a different frequency band and user base. That difference can become an advantage during emergencies.

Here are several reasons CB works well as a backup system:

1. Different Frequency Band
CB operates on 27 MHz (HF), while GMRS operates around 462–467 MHz (UHF). If conditions affect one band, the other may still function well.

2. Different User Community
Truck drivers frequently monitor CB Channel 19. During major highway incidents, weather events, or evacuations, this can provide valuable real-time information from people already on the road.

3. Infrastructure Independence
CB requires no repeaters or internet connections. Communication is radio-to-radio, which makes it resilient when systems fail.

4. Wide Availability
CB radios are inexpensive and widely sold. Many vehicles, especially in rural areas, already have them installed.

Weather Events and Emergency Use

In severe weather situations such as:

• Tornado outbreaks
• Ice storms
• Flooding
• Hurricanes
• Long-term power outages

communications infrastructure can fail quickly. A prepared household may have:

• A GMRS radio for family and neighborhood coordination
• A CB radio to hear highway and regional traffic reports
• A NOAA weather radio for official alerts

Each radio serves a different purpose, creating a layered communication strategy.

Staying Connected When It Matters Most

Preparedness is not just about having equipment—it’s about having options. The more communication paths available to you, the more likely you are to stay informed and connected during a crisis.

The WSHE379 GMRS network is built around community support and reliable communication. Adding a CB radio as an emergency backup strengthens that mission by ensuring members have additional ways to share information and reach others when conditions are at their worst.

A Simple Preparedness Step

If you already operate GMRS radios, consider adding a small CB radio to your emergency kit or vehicle. It’s a simple and affordable way to increase your resilience during severe weather and unexpected events.

When emergencies happen, redundancy saves lives.
Stay prepared, stay informed, and most importantly—stay connected.

Over the past few years, a new type of communication network has been gaining popularity in the amateur radio and maker communities: LoRa mesh networking. Two of the most talked-about systems are Meshtastic and MeshCore.

Both allow users to send messages across long distances using low-power radios without relying on cellular networks or internet infrastructure. For emergency communications, experimentation, and off-grid messaging, these systems are becoming an exciting addition to the modern radio toolkit.

Let’s look at what they are, how they work, and how you can get started.

What is LoRa Mesh Networking?

Both systems use LoRa (Long Range radio) technology operating in the license-free ISM bands (typically 915 MHz in the United States). LoRa allows radios to transmit very small amounts of data over long distances with extremely low power consumption.

Instead of communicating directly point-to-point, devices form a mesh network. Each radio node can relay messages to others, allowing communication far beyond the range of a single transmitter.

This makes it possible to:

• Send text messages across towns or cities
• Build off-grid communication systems
• Deploy emergency backup communications
• Track GPS locations
• Create sensor networks

Messages hop from node to node until they reach their destination.

What is Meshtastic?

Meshtastic is one of the most popular open-source LoRa mesh networking platforms today.

It uses inexpensive LoRa radios paired with a smartphone app to send and receive encrypted messages across the mesh network.

Key Features

• Off-grid text messaging
• AES-256 encrypted channels
• GPS location sharing
• Smartphone apps (Android & iOS)
• Easy setup and large community

Meshtastic uses a technique called managed flooding, where nodes rebroadcast messages so they propagate across the network. Messages typically travel up to 7 hops through other radios.

Best Use Cases

Meshtastic excels in situations where users are mobile or temporary, such as:

• Hiking and outdoor activities
• Public events
• Emergency response groups
• Amateur radio experiments
• Disaster preparedness

Because every node can relay traffic, a network can form automatically as users join.

What is MeshCore?

MeshCore is another open-source LoRa mesh system but designed with a different philosophy.

Rather than having every device relay messages, MeshCore uses dedicated repeater nodes to handle network routing. Personal devices are called companion nodes, which connect to repeaters but do not relay traffic themselves.

Key Features

• Structured routing architecture
• Multi-hop routing (up to ~64 hops)
• Store-and-forward messaging
• Optional end-to-end encryption
• Modular firmware roles (repeaters, companions, servers)

Because routing is more structured, MeshCore networks can be more efficient and less congested when properly designed.

Best Use Cases

MeshCore works best when you can deploy fixed infrastructure nodes, such as:

• Rooftop repeaters
• Solar powered hilltop nodes
• Community mesh networks
• City-wide emergency systems

MeshCore vs Meshtastic: Key Differences

Feature	Meshtastic	MeshCore
Network Type	Ad-hoc mesh	Infrastructure-based mesh
Routing	Managed flooding	Path-based routing
Hop Limit	~7 hops	Up to ~64 hops
Node Roles	All nodes can relay	Repeaters relay traffic
Ease of Setup	Very easy	More planning required
Community Size	Very large	Smaller but growing

In simple terms:

• Meshtastic = quick, easy, spontaneous networking
• MeshCore = structured networks with dedicated infrastructure

Many groups experiment with both systems, sometimes using the same hardware with different firmware.

Hardware You Can Use

Most mesh nodes are small development boards that combine:

• A microcontroller
• A LoRa radio chip
• Optional GPS
• Bluetooth or Wi-Fi

Popular hardware includes:

• LILYGO T-Beam
• Heltec LoRa32 V3
• RAK4631 WisBlock
• LILYGO T-Deck

These devices typically cost $20–$80, making them affordable for experimentation.

Most run for days on small batteries thanks to LoRa’s low power consumption.

Many of these boards support both Meshtastic and MeshCore, so you can simply re-flash firmware to switch between systems.

How to Get Started

1. Buy a LoRa Node

Choose a supported board like a T-Beam or WisBlock.

2. Install Firmware

Flash either Meshtastic or MeshCore firmware onto the device.

3. Install the Mobile App

Meshtastic has official Android and iOS apps.
MeshCore typically uses companion apps or command-line tools.

4. Connect via Bluetooth or USB

Your phone connects to the radio which becomes your gateway to the mesh.

5. Start Messaging

Once two or more nodes are online, the mesh begins forming automatically.

Range Expectations

Range depends heavily on terrain and antenna height.

Typical results:

• Urban areas: 1–5 miles
• Suburban areas: 5–15 miles
• Hilltop to hilltop: 30–100+ miles

With multiple nodes relaying messages, networks can span entire regions.

Why Amateur Radio Operators Are Interested

While these systems operate on unlicensed ISM bands, they share many principles with amateur radio networking:

• Digital experimentation
• Mesh networking
• Emergency communications
• Infrastructure building
• Community collaboration

Many amateur radio groups are experimenting with mesh nodes alongside traditional radio systems to create hybrid emergency communication networks.

Final Thoughts

Both MeshCore and Meshtastic represent a new generation of digital radio experimentation. With inexpensive hardware and open-source software, anyone can participate in building decentralized communication networks.

If you’re interested in experimentation, emergency communications, or just learning something new, LoRa mesh networking is worth exploring.

And as always in amateur radio…

The best way to learn is to get on the air and experiment.

WB4RL Repeater System News Release – March 2026

The WB4RL Repeater system continues to operate reliably and has seen several exciting upgrades and developments throughout March 2026, bringing enhanced digital communications and connectivity to the local amateur radio community.

Repeater Technical Information

The WB4RL repeater provides strong regional coverage and continues to serve as a central communications hub for local operators.

System Details

• Callsign: WB4RL
• Frequency: 443.8250 MHz
• PL Tone: 100.0 Hz
• Mode: FM Analog Voice
• Location: North Alabama region
• Coverage: Approximately 10–20 mile radius depending on terrain and station setup
• Linked Systems: AllStarLink Winlink and EchoLink

The repeater site also hosts several digital communication systems including packet radio, APRS services, and a Winlink RMS Gateway.

These systems operate together to support everyday communications, digital experimentation, and emergency communications capability throughout the region.

---

Winlink RMS Gateway – New “Post Office” Feature

One of the most exciting upgrades this month is the activation of the Winlink RMS Gateway Post Office function, which significantly expands packet radio capabilities available to local operators. The Winlink system operates on 2 Meters at 145.0500 24 hours a day.

Traditionally, a Winlink RMS Gateway serves as a connection point between radio users and the global Winlink email system. When a packet station connects to an RMS Gateway, the gateway normally forwards messages through the internet to the central Winlink servers.

The Post Office feature adds a local message server that can store and route messages directly between radio users entirely over RF.

How the Post Office Works

The RMS Gateway now includes a local message database that allows packet stations to exchange messages even if internet service is unavailable.

Operators connecting via packet radio can:

• Send messages to other local packet users
• Retrieve stored messages waiting in their mailbox
• Exchange traffic between stations connected to the system
• Store messages until the receiving station connects

Messages addressed to local stations remain stored within the gateway until the recipient connects and downloads them.

This essentially turns the system into a local packet mail server, similar to classic packet bulletin board systems used widely in amateur radio in the past.

Benefits for Packet Operators

Local RF Messaging

Stations can exchange messages entirely over radio without needing internet connectivity.

Emergency Communications

During disasters or outages, the gateway continues operating as a local message hub, allowing operators to pass traffic between stations and emergency groups.

Store-and-Forward Packet

Messages can remain stored until the receiving station connects later.

Training and Digital Experimentation

The system allows operators to practice digital messaging techniques commonly used in emergency communications.

Example Scenario

A portable station operating during a storm or public service event could connect to the WB4RL packet gateway and leave a message for another operator. The message remains stored in the local Post Office until the receiving station checks in and retrieves it.

If internet connectivity is available, the gateway will also continue routing messages to the global Winlink network as normal.

This hybrid capability allows the gateway to function as both:

• A global Winlink email gateway
• A local packet message system

---

APRS Network Performance

The WB4RL-10 APRS system has also been performing extremely well throughout the month. The system operates on the 2 Meter band at 144.390 MHZ 24 hours a day.

During the recent storms that passed through the region, numerous APRS weather stations were active across the network. Many of these stations successfully digipeated and IGated weather telemetry, helping distribute real-time environmental data.

Weather station packets included:

• Wind speed and direction
• Rainfall totals
• Barometric pressure
• Temperature and humidity

Several stations relayed this information through the WB4RL-10 APRS infrastructure, allowing reports to reach the wider APRS internet network and contribute to broader weather monitoring systems.

This activity demonstrates how amateur radio and APRS infrastructure can assist with situational awareness during severe weather events.

---

New T-Mobile 5G Internet Connection

Another major improvement to the WB4RL system is the installation of a T-Mobile 5G internet connection at the repeater site.

This high-speed connection now supports multiple communications services simultaneously, including:

• Winlink RMS Gateway operations
• APRS iGate services
• Packet radio networking
• Repeater monitoring and control
• AllStarLink connectivity
• EchoLink connectivity

The increased bandwidth and reliability of the 5G connection has noticeably improved the performance of digital services hosted at the site.

---

AllStarLink Node Operations

The WB4RL repeater is connected to the nationwide AllStarLink network, allowing the system to link with repeaters and nodes across the country. The WB4RL Allstar Node 556940 operates 24 hours a day.

With the new internet connection, the AllStar node has shown improved stability and audio quality. Operators can easily connect to regional or national nets and communicate with stations far outside the normal RF coverage area.

This connectivity significantly expands the reach of the WB4RL repeater.

---

EchoLink Connectivity

In addition to AllStarLink, the WB4RL repeater also supports EchoLink, allowing licensed amateur radio operators to connect to the repeater using internet-connected devices such as computers, smartphones, or other radios running EchoLink software. The WB4RL Echolink Node 454955 operates 24 hours a day.

This capability provides several benefits:

• Remote access for operators traveling outside the repeater coverage area
• Ability for operators without a local VHF radio to participate in repeater activity
• Additional linking capability with other EchoLink repeaters and conference servers

EchoLink support allows operators to stay connected to the local amateur radio community even when they are away from the region.

---

Amateur Radio News and Updates

Several developments across the amateur radio community have taken place recently.

The Federal Communications Commission (FCC) has extended certain amateur radio license renewal filing deadlines that were affected by the 2025 federal government shutdown, allowing additional time for operators to submit renewal applications.

Updates have also been implemented for the 60-meter amateur band, aligning U.S. amateur radio operation with international allocations approved during the World Radiocommunication Conference.

Amateur radio operators and scientists are also preparing for upcoming ionospheric research events and propagation studies that use amateur radio signals to better understand the upper atmosphere.

---

Looking Ahead

The WB4RL repeater system continues to evolve as a modern communications platform combining traditional FM repeater operation with advanced digital radio services on our 2 Meter and 70 CM radios and repeaters.

With the addition of the Winlink Post Office feature, strong APRS performance during severe weather events, EchoLink connectivity, and improved system infrastructure through 5G internet, the system is better equipped than ever to support:

• Daily amateur radio communication
• Digital experimentation
• Remote connectivity
• Emergency communications readiness

Operators throughout the region are encouraged to get on the air, explore packet radio and Winlink messaging, and take advantage of the many services provided by the WB4RL system.
