Off Grid Texting! Why Meshtastic u0026 What is it? Devices Antennas Setting Up u0026 What I've Learned

WA7JNJ Radio

What is Meshtastic and why is it something you may be interested in? Sending text message to family members by creating my own LoRA Mesh network, and having this network strengthened by others having mesh devices intrigued me after hearing an interview with some of the Meshtastic developers (Ham Radio Crash Course video link below).

I shared this presentation with our WA7LAW Snohomish County Hams Club on May 25, 2024, and wanted to make sure the information was available for those unable to attend. The presentation discusses: Why Meshtastic, How it works, How to choose devices, Antenna info, How to start basics, and my lessons learned so far. I've included the question time afterward in case you may have similar questions, or please reach out in comments and I'll do my best to help.

Video Updates:
Anker Powerbank not powering devices? Another user mentioned they had this issue with RAK device only, but were able to use power bank for Lilygo devices. Great commment provided that some Ankers have an "always on" mode that will power low consumption devices (activated by double pressing the power button).
Ham mode local SOTA POTA activator reached out and he has a device setup for making QSO's. Set device to ham mode, with zero hops (for simplex or direct only communication). I'm going to look into more, and would be fun to activate a SOTA summit using LoRA Meshtastic!
5/29 Tested devices today (portable units from the video RAK and LILYGO Supreme) from work parking lot to home (11 miles good line of sight). Excited that it worked to send a direct message! Need to check next time testing if it was direct or took one hop. Have been also confirm sending messages from kids school to home (about 1.5 miles), and downtown Marysville (~23 miles).
