Philosophy and Goals
This guide is about establishing practical, decentralized communications for neighborhoods. We believe in creating networks that are autonomous & resilient, and having fun while doing it. It’s not about being tactical cosplay preppers or lone-wolf electronics experts; it’s about equipping regular people with alternative comms that work. We use humor, beer, and backyard test-runs to build trust & muscle memory. Our goal is to turn casual hobbyists (and even laypersons) into calm, capable operators when it matters most.
Baseline Setup
Our foundation includes Meshtastic LoRa radios for text-based mesh networking, TAK (Team Awareness Kit) server for map-based coordination, VHF/UHF ham/GMRS radios for local voice comms, and HF ham radio for regional/long distance comms. Unlicensed neighbors can pick up a Meshtastic node and instantly become part of the network. We favor the LilyGO T-Deck for its standalone utility (screen, keyboard, no phone required).
"Field" Ops
We communicate from backyards, parks, and hiking trails with battery-powered portable HF and VHF/UHF gear. Our most successful DX (long-range) radio contact was from Florida to Finland on 40 meters with 50 watts from a backyard home-brew HF setup. Propagation planning is done casually, often by ear and experience. Frequency plans are ad hoc but increasingly informed by field testing & ARRL band plans. Power comes from a mix of LiFePO4 packs, solar, and USB banks.
Advanced Layering
We layer in TAK integration via a bridged Meshtastic node. This allows text and location data to flow directly into the TAK server and map interface. SDR gear feeds ADS-B (aircraft), AIS (ships), and drone data into TAK to build a live situational picture. This keeps people on our neighborhood network not just in-touch, but aware.
Emergency Activation Plan
If the normal comms go down (e.g., hurricane aftermath), the plan is simple: text messages can be sent over the mesh network by anyone, while licensed users spin up the VHF/UHF voice nets. HF can be used to relay messages outside of the immediate area. Conditions permitting, individuals circulate the neighborhood to check on neighbors and relay updates about those in need. Comms traffic should stay light, concise, and intentional. Roles are informal but encouraged; relay runner, mapping hub, radio operator, local scout. We practice these things casually so activation will feel natural.
Tools & Scripts
We’re currently building scripts to automate TAK backups & restores, Meshtastic node config exports, and SDR sensor backups. We plan to share hardware photos, config dumps, and wiring diagrams in an open repository. It won’t be pretty, but it’ll do. These systems aren’t meant to impress, they’re meant to survive.
