Demonstrates the practical application of APRS (Automatic Packet Reporting System) through the lens of HB9PVI's activities in Switzerland. It covers the system's core function of reporting geographical positions and telemetry data from various objects, including mobile stations, aircraft, and the ISS, distributed via packet radio and internet gateways. The resource highlights the routing paradigm shift introduced in April 2005, specifically the recommendation to use _WIDE1-1_ instead of RELAY and WIDE for digipeating to reduce duplicate packets. The page presents real-time maps displaying the positions of amateur radio stations in Switzerland and around Bern, updated every few minutes. It details specific callsigns like _HB9BA-2_ (HB9PVI's home QTH), _HB9BA-8_ (a weather station), and _HB9BA-4_ (a WIDE digipeater on Weissenstein mountain), providing context for their roles within the local APRS network. Links to track HB9PVI's mobile operations (_HB9PVI-9_) and handheld devices (_HB9PVI-15_, _HB9PVI-7_) are also provided. Furthermore, the resource curates a list of APRS software options for various operating systems, including _JavAPRS_ for Europe, _UI-view_, and _X-Astir_ for Linux, alongside digipeater/IGATE software like _DiXPRS_. It also offers downloadable APRS information, including a PDF article by HB9PVI and HE9ZGN, and a PowerPoint presentation in German, making it a repository of practical and historical APRS data.

Heil Sound PR-35 vs Heil Sound PR-781 vs Electro Voice Blue Cardinal by K4QKY

The online Morse code translator and decoder provides functionality for converting plain text into Morse code and decoding Morse code back into text. Users can input text directly into a designated box for translation to Morse, with the tool ignoring characters that lack a Morse equivalent. Conversely, Morse code can be entered using periods for dots and minus signs for dashes, requiring a single space to separate letters and a forward slash to delineate words. The interface also supports direct Morse input via a button, where a half-second pause separates letters and a 1.5-second pause separates words. The resource details the historical context of Morse code, noting its invention by _Samuel F.B. Morse_ in the 1830s for telegraphy, and its continued use by amateur radio operators for recreational purposes and emergency signaling, such as the **SOS distress signal**. Guidance on learning Morse code suggests using online translators for practice and listening to amateur radio transmissions. The tool offers an audio playback feature for translated Morse, allowing users to hear the code at various words per minute (WPM) settings. It also includes a visual chart to aid in memorizing the dot and dash sequences for the alphabet.

This article documents the author's latest go-box build for outdoor ham radio operations using a Yaesu FT-891 transceiver. The go-box is constructed from a plastic "50-cal ammo case" and contains various components, including the transceiver, LDG Z11 Pro autotuner, DIY Yaesu FH-2 remote control keypad, and an external battery. The author details the design considerations, the mounting of components inside the box, and addresses issues related to ventilation and cable management. The go-box is geared for CW operations and POTA activations, with further modifications planned for a microphone and DATA jack. This project allows for rugged, environmentally protected outdoor radio operations while maintaining portability.
