Edward F. "Ed" Hare, Jr., W1RFI, a long-time ARRL Lab engineer, passed away on October 10, 2025, at the age of 75. He was a dedicated ham radio operator, RFI expert, and contributor to ARRL advocacy efforts.
Frozen intends to be a radio BBS optimized for slow connections. This is the very beginning of the project. It has a working message board, admin tools, a terminal client, and a server supporting serial and TCP connections to Meshtastic radios.
This article details a dsPIC-driven radio build by Minh Danh that receives FM and AM (all bands, SW, MW, LW), plays MP3s from USB, and records incoming signals. It highlights the use of Si4735 for radio functionality, TDA1308 and NS8002 for audio, and a resistor ladder for front panel button input. The project is praised for its thorough documentation.
A Python package for looking up DMR IDs from radioid.net. It's a lightweight command-line tool with features like callsign lookup, pretty table output, CSV saving, and ID lookup.
"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.
Researchers discovered that renewable energy facilities across Central Europe use unencrypted radio signals to control power generation, posing a potential threat to the grid. If intercepted and manipulated, these signals could disrupt grid stability by causing power imbalances, possibly leading to a continent-wide blackout. This raises significant concerns about the security measures currently in place and the need for more secure alternatives like iMSys, which uses encrypted LTE for communication.
Application for Flipper Zero device to control radio boards. Supports the TEA5767 board and includes pin configuration instructions. Inspired by Arduino Radio project with acknowledgments to contributors.
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.
Dr. David Todd and C.F. Jenkins attempt to intercept signals from Mars using a Jenkins Radio Camera in 1924.
