The resource, formerly JH6QIL's blog, now displays a service termination notice from teacup. byGMO, the hosting provider. It explicitly states that the teacup. byGMO service ceased operations on August 1, 2022. The page conveys a message of gratitude to users for their past patronage of the platform. This content serves as an archival record of the service's discontinuation rather than an active amateur radio blog. The original blog content from **JH6QIL** is no longer accessible through this URL, indicating a complete cessation of the hosted service.

The G5O Contest Group blog documents contest operations and related activities of the Stockport Radio Society. It covers various **HF** and **VHF** contests, providing insights into station setup, antenna configurations, and operational strategies employed during events. The content frequently includes post-contest analyses, discussing scores, propagation conditions, and technical challenges encountered. The blog entries detail specific contest participations, often featuring photographs of the operating environment and equipment used. It serves as a chronicle of the group's contesting history, offering practical examples of multi-operator station management and logistical planning for competitive amateur radio events. The group's focus on both local and international contests is evident through the range of events covered. Regular updates provide a continuous record of the group's engagement in the amateur radio contesting community.

Documents the _XT1T_ DXpedition to Burkina Faso, active from February to March 2013. This operation provided DXers worldwide with an opportunity to work a relatively rare entity, with the team focusing on maximizing contacts across various bands and modes. The expedition utilized an online log provided by _IDT_ (Italian DXpedition Team), enabling immediate verification of contacts and facilitating QSL requests. The _IDT_ system allowed participants to check their QSOs shortly after they were made, a crucial feature for contesters and award hunters aiming for DXCC credit. The expedition's success was measured by the total number of unique contacts and countries worked, contributing significantly to the global DX community's pursuit of new entities.

Visualizing DXCC award progress often requires manual parsing of Logbook of the World (LoTW) reports, which can be time-consuming and prone to error. This web-based utility streamlines the process by allowing hams to upload their LoTW DXCC Credit Report spreadsheet, providing an interactive dashboard for tracking confirmed entities, bands, and modes. It processes .xlsx, .xls, and .csv files, performing all calculations client-side within the browser for privacy and speed. The tool presents a comprehensive stats overview, detailing total entities, confirmed slots, and overall completion percentage. It includes progress bars for bands from _160m_ through _2m_, and modes such as CW, Phone, and DIG. A sortable DXCC Entity Details Table lists each entity, its confirmed count, and specific missing band/mode slots, with a CSV export option. Further features include a Band/Mode Matrix grid for granular confirmed status per entity, toggles for specific bands like _6m_ and _2m_, and tracking for DXCC Challenge progress across 10 eligible HF/VHF bands. It also highlights nearly complete entities and identifies most-wanted DXCC entities based on the uploaded data.

Analyzing 433 MHz radio signals from common wireless devices, such as temperature sensors and remote controls, involves understanding **On-Off Keying (OOK)** modulation. This resource details the process of capturing these signals using a Software Defined Radio (SDR) like Gqrx and then visually inspecting the captured audio data in a sound editor such as Audacity. It differentiates between **Pulse Width Modulation (PWM)** and Pulse Position Modulation (PPM) encoding schemes, illustrating how to identify and decode binary data by eye based on pulse and gap durations. The article provides a step-by-step walkthrough for decoding a wireless thermometer's data, correlating bit patterns with known temperature, humidity, and channel values. It also demonstrates decoding an RF remote control's button presses, highlighting the constant and varying parts of the transmitted packets. The content further introduces automated decoding using tools like RTL_433, explaining its capabilities in parsing various device protocols and showing how to interpret its output, including modulation type and decoded data. Specific examples include analyzing Prologue sensor protocol specifications from RTL_433's source code and noting common operating frequencies like 433.92 MHz in Europe and 915 MHz in the US.
