Mesh radio communication is a network topology where each node in the network can relay data to other nodes, creating a robust and flexible communication structure. This approach is used in various technologies, including LoRa, and other waveform techniques.

  1. Mobile Ad-hoc Network (MANET)
  • Decentralized
  • self-forming, self-healing network.
  • Wireless networks
  • Autonomous
  1. Modern MANETs
  • Are highly advanced and use SDR
  • Can be integrated into vehicle platforms (Ground & Aerial)
  • Encrypted
  • Broadband

If you are looking to build a robust P.A.C.E that fill the need for encrypted FHSS mesh technology communications you should look at the Beartooth Radio.    

The interest in LoRa mesh communication is blowing up. The first place you will notice is when you go buy one online. Between the manufacture direct site or through distributors you find “out of stock” as common phase on these sites. Even if the website doesn’t say the stock beware because you may be waiting much longer than normal for your to be fulfilled. With that said, this is a good problem because there are more LoRa nodes in the network. If are lucky those nodes may be in your local area thus increasing your local network size.  

In this video I make my case for purchasing GMRS handheld radios. Additionally, we discuss the future of GMRS technology. Radio manufactures are now building radio that texting and GPS location sharing feature which could really up you emcomm game.   

It is time to up my game and expand my local mesh network. If you are asking yourself what a mesh network is or LoRa. Here is a short explanation. LoRa mesh networks utilize the Long Range (LoRa) technology to create a decentralized and self-configuring network infrastructure. These networks consist of numerous LoRa-enabled devices that can act as both end nodes and routers, allowing for data transmission over long distances with low power consumption. Each device in the network communicates directly with neighboring devices, forming a mesh-like structure where data can hop from one device to another until it reaches the intended destination. This mesh architecture enhances network coverage, improves scalability, and provides robustness by offering multiple communication paths, enabling reliable and efficient communication for various applications such as smart cities, industrial monitoring, agriculture, and environmental sensing.

LoRa Mesh communications offer numerous benefits that make them a compelling choice for various applications. One key advantage is their ability to create a decentralized network, eliminating the need for a centralized infrastructure like cell towers or Wi-Fi routers.

Mobile radio go bag project

I have been looking to solve a communication problem I had for some time now. I am a member of my local ARES team and a prepared-minded person. Hence, amateur radio communication equipment in my vehicles is a must. However, with multiple vehicles and teenagers that are sharing them. Permanently equipping each vehicle is impractical and expensive.
My solution is to build a “go bag” for an Anytone 578 mobile radio. Stay tuned for future updates as this project develops.

I am super excited about the possibilities of these two-way communication devices. I have added two more to my collections and will likely add more in the future. To learn more watch the video above and checkout meshtastic.org

Does encrypted off-grid communications interest you? If the answer is yes then you should check out LoRa Meshtastic devices. 

Amateur radio can be intimating however, there is no replacing its versatility. Especially when it comes to emergency situations amateur is nearly irreplaceable, even with today’s smart devices. 

Your mobile communications equipment is only as good its batteries. Therefore, it is crucial you build comms kits to support your devices. 

Cell phone have become an integral part of our daily lives. In an emergency cellular service can be interrupted but not always. Additionally, cellular service companies have several clever ways to rapidly restore service after a disaster. In this video I provide some tips for using your cell phone before, during, and after a disaster.

This week’s Emergency Communication Plan video is about monitoring radio communications using devices like Scanners, Shortwave Radios, Software Defined Radio (SDR) and even your basic AM/FM radios. 


General Mobile Radio Service (GMRS) it the best option for back-up comms for most. Thre main reasons: no test, affordable, off the shelf ready and easy to use with little to no training. 

Today we explore developing P.A.C.E plans as the foundation of our emergency communication plans. Do you still have questions about P.A.C.E then check the website: https://medium.com/firewatch-solutions/emergency-communications-what-is-a-pace-plan-694f14250bd2


Today I start a seven part series of emergency communication. This is a category of preparedness that is often over looked yet, is very important.

I have been using the Storm2 Liquid Power bank for two months now. One of the reasons I bought this was for the adjusted output voltage feature. This allows me to recharge things like Handheld Radios while in the field. I had to purchase an USB C to 5.5 x 2.1 mm adapter cable from Amazon to allow me to charge my Anytone 878 DMR HT.

Storm2 Specs:

100W PD In/Out | 27600mAh/99.36Wh | 3.3-25.2V DC Out | 2 USB-C+USB-A+DC | Airline Safe | Compact Battery Bank
