Online Log for D64K Comoros Island DX Pedition 2012

A shortwave radio listeners log book runs on Windows and MacOS Catalina and above. The KB6IBB SWL Logger is a program designed for the shortwave radio listener. It offers shortwave specific logging of stations, with most tasks handled automatically. The program also incorporates the use of EiBi shortwave database for logging and looking up various known shortwave stations world wide.

The F5GIT blog documents the amateur radio pursuits of Tony, F5GIT, offering insights into his DXpedition experiences and contest operations. It presents detailed accounts of his participation in events like the _CQ WW DX Contest_ and the _IARU HF Championship_, often including specific callsigns worked and operational strategies employed. The resource covers various aspects of station setup, antenna configurations, and radio equipment used for achieving contacts across different bands. Content includes discussions on antenna performance, such as a **2-element Yagi** for 10/15/20 meters, and operational challenges encountered during remote or portable setups. The blog also serves as a personal log, chronicling significant QSOs and providing a historical record of his amateur radio journey. It details specific locations operated from, like _Île de Ré_, and the unique challenges presented by such environments. Furthermore, the blog provides practical information on optimizing station efficiency and maximizing contact rates during high-intensity operating periods. It reflects a dedicated approach to improving radio skills and contributing to the global amateur radio community through active participation and sharing experiences.

TACLog offers a distinct approach to contest logging for **VHF/UHF/SHF** operations, diverging from the rigid input formats often found in other logging applications. This software prioritizes operational freedom, allowing contesters to input data in a sequence that suits their workflow during a fast-paced event, rather than being constrained by predefined field orders. It's particularly tailored for those participating in contests governed by **Region 1 rules**, ensuring compliance with established regulations. The program's design focuses on practicality for serious contesters, providing a robust platform for managing contacts. Its support for the EDI format is a significant advantage, streamlining the process of submitting logs to contest committees and facilitating data exchange within the amateur radio community. My experience with various logging tools confirms that flexibility in data entry can dramatically improve efficiency during multi-operator or high-rate single-operator contests, where every second counts.

The resource examines the operational characteristics and potential of Moxon Yagi antennas, drawing insights from Les Moxon's work and subsequent NEC modeling. It presents simulated current distributions and radiation patterns for a 40-meter Moxon, comparing its performance against a standard 2-element Yagi on the same band. Specific data points include forward gain, front-to-back (F/B) ratio, and feedpoint impedance, which are critical parameters for antenna design and optimization. Further analysis extends to a 20-meter Moxon, detailing its gain, F/B ratio, and SWR bandwidth across the band. The discussion highlights the Moxon's compact footprint and its ability to achieve respectable performance metrics, making it a viable option for hams with limited space. The content provides a technical assessment of the Moxon's advantages in terms of pattern purity and impedance stability compared to other compact directional arrays. The article also touches upon the practical considerations for constructing and deploying Moxon antennas, emphasizing the trade-offs between physical size and electrical performance. It includes graphical representations of antenna currents and radiation patterns, offering visual aids to understand the theoretical concepts discussed.
