Why the RM-2

2 watts of transmit power. Double the RM-1's output, for more signal headroom through terrain, timber, and noisy RF. When the repeater doesn't reach the canyon floor, the RM-2 gives you more to work with.
Built to take a beating. Extruded-aluminum housing, rubber shock bumpers at both ends, sealed waterproof USB-C, and a durable gooseneck antenna. IP-68 / MIL-STD-810H (certification pending).
Best-in-class antennas. An active helical GNSS antenna for precise location fixing in any orientation, and a custom-tuned LoRa antenna for high performance and pristine signal quality.
American-made LoRa board. A new U.S.-manufactured PCB designed by AT-Labs, built around the Ebyte E22-900M33S module. Designed and assembled in the U.S.
Fits your team's kit. Same size as the RM-1, works with every RM-1 accessory, and runs on the same mesh as your RM-1s and standard Meshtastic channels. Runs Meshtastic, MeshCore, or Reticulum with no subscription.
Firmware that is easy to find and manage. Every RM-2 ships with AT-Labs firmware loaded and transmit power already set. Builds and updates live on the AT-Labs firmware site.

Built for SAR teams, field medics, community responders, and civilians who expect their gear to work when everything else fails. The RM-2 fits the team whose last training op hit a dead zone and needs more power per node.

Portable or Infrastructure

From the field

"This thing punches through RF when nothing else will. Some say higher power defeats the purpose of Meshtastic — but in RF-dense environments, you need it. The RM-2 lets me hit an antenna site flooded with 900MHz noise and still cut through the noise. This thing's awesome."

Michael T., Verified Buyer

"If you're considering an RM-2, you're getting a thoughtfully built American-made product and a team that genuinely stands behind it."

Setting up your RM-2

Every RM-2 ships with AT-Labs firmware already loaded and transmit power already set. Getting on the mesh takes three steps.

Attach the antennas.
Turn on the radio.
Pair with your phone. Use the Meshtastic app. You're ready to go.

Updating the firmware

When an update is due, follow our step-by-step guide: How to update the firmware on your Meshtastic radio. AT-Labs builds for Meshtastic, MeshCore, and Reticulum are at firmware.at-labs.tech. Flash over USB, since the aluminum housing blocks Bluetooth too much for a reliable update.

Keep TX power at 8 or below. If you ever flash stock firmware or reset the radio, set LoRa TX power to 8 before you set the region. Settings above 8 permanently damage the radio module and are not covered by warranty. The AT-Labs firmware holds this setting for you, so if you stay on it there is nothing to manage.

Every RM-2 is covered by AT-Labs' 1-year warranty.

The RM-2 is a Part 97 device. Operators are responsible for running it within the laws of their region.

When to choose the RM-2

If you work somewhere you have to be sure your signal gets through, the RM-2 is the node for you. The extra power gives your signal its best chance to get out. That is what the 2W buys you.

It runs on the same mesh as the RM-1 and standard Meshtastic channels, so it drops into a team that already has radios in the field.

FAQ

What's the difference between the RM-1 and RM-2?

The RM-2 is AT-Labs' flagship. It has the same housing, battery class, and accessories as the RM-1, plus double the transmit power (2W vs 1W), a new American-made LoRa PCB, IP-68 sealing (certification pending), and the RC-2 charger with 12V DC input. Both run on the same mesh.

Why does the RM-2 cost so much?

Every part in the RM-2 is the best available on the market, and the whole radio is custom built for first responders and search and rescue. Nothing was cut to hit a price point. Portable is $795 and Infrastructure is $895, and each ships with the RC-2 Quick Charge Adapter.

Portable or Infrastructure: which one do I need?

Portable is worn or carried and built for individual field use. Infrastructure is a fixed repeater with mounting brackets and a solar panel, meant to run unattended and extend your team's coverage. Most teams start with a mix: portables for personnel, infrastructure for fixed high points.

What's in the box?

The RM-2 radio, RC-2 charger, GNSS antenna, custom-tuned LoRa antenna, and a waterproof USB-C cable.

Does the RM-2 handle video?

No. The RM-2 isn't a video platform. Text and GPS come first. If your team needs video over mesh, look at NATAK Mesh's Nucleus.

Will the RM-2 work with my RM-1s?

Yes. It's backward-compatible with RM-1 nodes and standard Meshtastic channels as long as both run the same core firmware, and every RM-1 accessory fits.

Can I upgrade my RM-1 to an RM-2?

No. The RM-2 uses a different radio module, so it isn't a firmware unlock. Your RM-1 accessories all carry over to a new RM-2.

Is there a pouch for the RM-2?

Yes. We recommend the SX-E Radio Pouch, custom built for the RM family of radios. A standard tactical radio pouch works too.

Is this the right radio for a SAR team?

Yes, when you need a pouch-compatible mesh node with days of battery, open firmware (Meshtastic / MeshCore / Reticulum), and more power per node, on U.S.-assembled hardware you can hand to volunteers with no subscription.

How is this different from a $30 Meshtastic board?

A $30 board is a starter node. These are duty radios: a custom-built board, an aluminum housing that fits standard radio pouches, a ~10 Ah battery for multi-day missions, and an ~8-week made-to-order build. Same open mesh idea, different job.

How long until it ships?

Each RM-2 is built to order by AT-Labs and ships in about 8 weeks. For bulk or international orders, email sales@constellationresponse.com.

I do not normally write reviews

I do not normally write reviews, but Constellation Response earned this one.

After ordering two RM2 radios, I noticed that both had an excessive power-drain issue. I contacted Rob and Kenny, explained what was going on, and sent both radios back for evaluation. They addressed the problem immediately, corrected the issue, and got the radios returned and back in service quickly.

What stood out most was the customer support. Whether I have called or emailed with a question, Rob has been quick to respond with a clear, knowledgeable, and genuinely helpful answer. It is refreshing to deal with a company that stands behind its equipment and treats customers like their concerns matter.

The RM2 radios are a valuable part of my communications setup, and it gives me confidence knowing Constellation Response is responsive, capable, and committed to taking care of its customers. Highly recommended.

A genuinely American-made product, backed by people who care

I recently purchased an RM-2 and wanted to share my experience, because both the product and the people behind it deserve the recognition.

The RM-2 is American-designed, manufactured, and tested in Tennessee — and that matters. I ordered through an authorized retailer, starting with the stock infrastructure configuration. Midway through the order, I asked Rob at Constellation Response if a small custom deviation was possible. Not only did he accept the request without passing along any additional cost, he also took the time to ask about my specific usage so he could better understand how customers are actually putting the RM-2 to work. That kind of curiosity from a vendor is rare.

The custom request did push out the delivery timeline, but honestly it never felt like a problem. Rob was completely transparent throughout — clear updates, realistic expectations, no guesswork on my end. And knowing that Kenny and his team at AT Labs were heads-down doing what they do best, manufacturing and testing a genuine American-made product, made the wait feel worthwhile.

When the RM-2 arrived, it was carefully wrapped and packaged. One small detail I appreciated: a fine layer of red clay dust on the unit itself — a quiet signal that it had almost certainly been individually tested before being boxed up and sent my way. That kind of attention to detail tells you everything you need to know about how this product is made.

The included documentation was helpful, but what I valued most was the post-purchase Q&A correspondence with Rob and Kenny. They patiently walked me through where I had misinterpreted certain aspects of the RM-2, reset my understanding, and made sure I had the right expectations going in. On top of that, the Bluetooth connectivity has been outstanding — better than I expected.

If you're considering an RM-2, you're getting a thoughtfully built American-made product and a team that genuinely stands behind it. I couldn't recommend Rob, Kenny, and the work coming out of Constellation Response and AT Labs more highly.

I don't normally do reviews-- HOWEVER the RM-2 is IMPRESSIVE.

I don't normally do reviews; however, I purchased a RM-2 to evaluate and was impressed with it. Not only is it solid and ruggedly built but it punches through when other equipment doesn't connect in side by side comparisons. The support has been outstanding ... I had questions before and after my purchase. I highly recommend this radio!

Goes the distance when needed.

Aside from its absurdly rugged appearance and capabilities, this thing punches through RF when nothing else will. Some people say higher power defeats the purpose of MeshCore or Meshtastic but people don’t realize that sometimes extremely RF dense environments are impossible to get through. The RM-2 allows me to hit an antenna site, flooded with 900mhz RF and get through the noise. This things awesome.
