Thomas Witherspoon recounts his renewed appreciation for the Elecraft K2 kit radio, highlighting its enduring appeal, build quality, and performance in both shack and field operations as of 2025.
* **Nostalgic Rediscovery:** Thomas rekindled his love for the K2 after using it on field activations, appreciating its superior audio quality and low noise floor, which make it a pleasure to operate.
* **Kit Radio Advantages and Challenges:** The K2’s status as a kit radio offers excellent serviceability, repairability, and long-term support, though build quality can vary and requires careful inspection when purchasing used.
* **Enduring Value and Legacy:** Despite being over two decades old, the K2 remains a highly satisfying and reliable transceiver, valued by operators for its simplicity, craftsmanship, and suitability for both QRP and QRO operations.

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.
Meshtastic is an open-source mesh networking platform designed to facilitate decentralized, long-range, and ad-hoc communication. This article provides a full guide on how to get started, covering its features, use cases, compatible hardware, and setup instructions.
QSL World offers an AI-powered tool to visualize ham radio contacts by uploading ADIF files and generating an interactive map. The tool integrates with QRZ.com for accurate data and allows users to select QSL card designs for confirmations.
It is a high-performance tracker designed for Meshtastic, as small as a credit card, effortlessly fitting in your pocket or attaching to your assets. It embeds Semtech's LR1110 (Supports 863-928 MHz range), Nordic's nRF52840, and Mediatek's AG3335 GPS module, providing Meshtastic users with a high-precision, low-power positioning and communication solution.
OpenEmbed is creating the MeshWalkie, a Meshtastic-ready LoRa handheld using the housing of a Baofeng UV-K6 radio. It features an Espressif ESP32-S3, a Seeed Studio Wio-SX1262 LoRa transceiver, and a Seeed L76K GNSS receiver, all on a custom PCB. The project aims to provide a rugged, open-source alternative to 3D-printed or expensive injection-molded handhelds.
This article discusses the role of amateur (ham) radio as an educational tool, a driver of innovation in telecommunications, and an inclusive community for STEM learning. It highlights the challenges ham radio faces regarding public perception and spectrum allocation, while advocating for its continued support and expansion in education.
Meshnology offers a range of IoT and Meshtastic related products including ESP32 LoRa modules, batteries, antennas, development boards, sensors, and cases.
This project details building a system to send images in real-time from high altitude using SSTV (Slow-Scan Television) and PMR walkie-talkies. It covers hardware setup, code configuration, and launch results. Note: PMR is under ham radio license in US.
