MeshCore Presentation in Nacogdoches | November 3, 2026

What if you could send text messages across town without using a cell tower, Wi-Fi network, or Internet connection?

That is one of the ideas behind MeshCore, and we’ll take a closer look at it at the next meeting of the Nacogdoches Amateur Radio Club.

The presentation will be held:

Tuesday, November 3, 2026 at 7:00 PM
Nacogdoches County Emergency Operations Center
727 FM 3314, Nacogdoches, TX 75964

What Is MeshCore?

MeshCore is a communications system that uses small LoRa radios to send digital messages over radio.

A personal MeshCore device can connect to a smartphone through Bluetooth. Your phone gives you the screen and keyboard, while the small radio handles the actual radio communication.

Dedicated repeaters can then help those messages travel farther.

In simple terms, it can look something like this:

Phone → Personal Radio → Repeater → Another Radio → Another Phone

The local radio network can continue working without depending on the Internet.

What Will We Demonstrate?

Andy Delgado, KE5EXX, will share some of the MeshCore equipment he has been experimenting with and explain how the pieces work together.

The presentation will include personal Companion nodes that connect to a phone by Bluetooth, along with a solar-powered MeshCore repeater that can operate independently from normal household power.

We will also look at some of the ideas we have been exploring for a local network around Nacogdoches.

That includes placing repeaters at useful locations, extending coverage from one part of the community to another, and eventually exploring things such as Room Servers and optional Internet gateways.

No, we are not building Skynet.

At least not Tuesday night.

Why Is This Interesting to Amateur Radio Operators?

MeshCore is not a replacement for amateur radio, public-safety communications, or cellular service.

It is another technology worth learning about.

For amateur radio operators, it combines several familiar ideas:

  • radio propagation
  • antennas and elevation
  • repeaters
  • solar-powered equipment
  • portable communications
  • network planning
  • experimentation

It also gives us a chance to work with technology that may be useful in places where ordinary Internet or cellular coverage is limited.

And because the equipment is relatively small and low-powered, it opens up some interesting possibilities for portable and remotely powered installations.

Could We Build a Local Network?

That is one of the questions we want to explore.

Imagine several repeaters around Nacogdoches. Personal nodes could communicate through whichever repeater or path was available.

Later, other communities could build their own local networks and experiment with ways to connect them.

We are still very much in the learning and testing stage, which is part of the fun.

Rather than starting with a finished system and a stack of claims about what it can do, we want to build it, test it, measure it, and learn from the results.

Everyone Is Welcome

You do not need to own a MeshCore radio.

You do not need to understand LoRa.

You do not even need to be an amateur radio operator to find the technology interesting.

If you are curious about radio, mesh networking, off-grid communications, solar-powered electronics, or just enjoy seeing new technology in action, we would be glad to have you join us.

Tuesday, November 3 at 7:00 PM.

Come see what we have been experimenting with and help us explore where this might go next.

What Is Amateur Radio, Anyway?

Imagine sitting at a picnic table in East Texas, connecting a radio to an antenna, and hearing someone answer from another state. On another day, with the right setup and conditions, that answer might come from another country.

That’s one part of amateur radio, better known as ham radio. But long-distance conversations are only the beginning.

So, what is ham radio?

Amateur radio is a hobby and a communications service in which licensed operators use radio equipment to communicate, learn, and experiment. The people who participate are often called “hams.”

In the United States, amateur radio operators are licensed by the Federal Communications Commission, or FCC. We’ll cover how to become licensed in a future article. For now, you don’t need an electronics background to understand the appeal.

A radio contact might be a conversation across Nacogdoches, a quick exchange with someone across the country, or a hello from halfway around the world. How far you can reach depends on your equipment, antenna, frequency, conditions, and the way you communicate.

Sometimes the fun is the conversation. Sometimes it’s the surprise of where your signal ends up.

Is it the same as CB radio?

Both let people communicate by radio, but they’re different services.

CB, short for Citizens Band, uses a defined set of channels and doesn’t require an individual FCC license in the United States. Amateur radio requires licensing and offers access to a wider range of frequencies and ways to communicate, along with opportunities to build and experiment with equipment.

There’s room to enjoy both. Someone who likes chatting on CB might also find plenty to enjoy in ham radio.

There’s more than a microphone

Ask several hams what they enjoy, and you may get several different answers. The hobby includes:

  • Voice conversations: Catching up with nearby friends or meeting someone far away.
  • Morse code: Sending messages using patterns of short and long signals.
  • Digital communication: Connecting radios to computers to exchange text, images, or other information.
  • Satellites: Communicating through amateur radio satellites orbiting Earth.
  • Portable operation: Taking a radio and antenna to a park, campsite, or other outdoor spot.
  • Experimenting: Building an antenna, adjusting equipment, and seeing what works.

Some operators enjoy contests, trying to make as many contacts as possible within a set time. Others collect contacts from different places or simply enjoy a relaxed conversation.

You don’t have to enjoy every part of the hobby. You can find the part that makes you want to turn the radio on.

Why bother when we have smartphones?

Because making a connection yourself can be fun.

Sending a message on your phone is convenient. Sending one through a radio system you’ve assembled offers a different kind of satisfaction. It’s a little like the difference between buying vegetables and growing a garden.

Modern ham radio also makes use of computers, digital technology, GPS location information, and internet-linked systems. Some methods use those tools; others can work independently of phone networks and the internet.

Public service is another reason people participate. Trained volunteers can help with communications at community events or supplement normal communications during emergencies. That provides another option when appropriate, rather than replacing police, fire, or professional emergency systems.

For others, the draw is friendship, preparedness, technology, or the chance to try something new.

Start with a little curiosity

Here in East Texas, the Nacogdoches Amateur Radio Club, W5NAC, gives that curiosity a local starting point. Our website has information about club meetings, getting licensed, and becoming involved in amateur radio around Nacogdoches.
