Meshtastic is an off-grid mesh network for short messages, but its use is limited by the need for a phone app or web UI. The T-Deck offers a standalone solution, though it has its issues. The article covers the installation and use of the experimental T-Deck UI firmware, its limitations, and community reactions.
An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices.
"This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an Arduino library for the SI473X BROADCAST AM, SSB and FM/RDS RADIO RECEIVERS. Frequency ranges of AM and SSB modes are 150kHz to 30MHz, and FM mode is 64 to 108 MHz."
This repository is intended to share implementations using the Si4735/Si4732 chip with the library written by PU2CLR/Ricardo Caratti. It includes projects for TTGO T-Display Board and Lilygo T-Display S3 Board.

The article highlights the importance of preserving the history of amateur radio through the Digital Library of Amateur Radio and Communications (DLARC) project.
Nick Farrow has created MeshBoard, a text-based bulletin board system inspired by the BBSes of the 1970s and 1980s, running on a Raspberry Pi using the Meshtastic mesh network. The project allows for menu navigation and interactive games like Tic Tac Toe and an Escape Room, with no internet required. It leverages Python to create a modular and easily extensible platform, with plans to expand features such as file transfer over the Meshtastic network.
GUI application for using HackRF as a spectrum analyzer with features like optimized settings, easy retuning, peak/persistent display, and more.
Google researchers demonstrated the ability to use GPS signal measurements from millions of anonymous Android mobile devices to map the ionosphere with high accuracy, potentially improving GPS navigation worldwide.
This GitHub repository contains the development of an APRS hub that transmits various sensor data like spO2, location, and altitude. The project uses Raspberry Pi, Tiny Circuit Python boards, and MQTT for data transmission.
