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 AT-AUTO automatic antenna tuner handles 1.5kW CW operation, employing stepper motors under microprocessor control to precisely position a roller inductor and air-dielectric variable capacitor, avoiding relay-switched discrete components. This design choice prevents loud relay clacking and burning contacts, a common issue with competing products. The tuner features auto-retuning capabilities and receives periodic firmware updates, ensuring continuous improvement and added user-requested features. Its companion product, the _CX-AUTO_ coaxial switch, also features an embedded microprocessor controller. It enables selection of 1-of-8 coaxial outputs via a serial data interface. When integrated with the _AT-AUTO_, the tuner can associate specific coaxial outputs with amateur radio bands, automatically commanding the _CX-AUTO_ to select the correct antenna when the operator QSYs to a different band. Don Kessler began designing the AT-AUTO in 2005, with its debut at the 2006 Dayton Hamvention. Kessler Engineering also offers custom RF product design and electrical engineering consulting, specializing in Class-E RF amplifiers. -

Over 20 distinct discussion categories are available on the Amateur Radio Discussion forum, encompassing a wide array of topics relevant to radio enthusiasts in the UK and beyond. The platform facilitates exchanges on technical aspects of amateur radio, including antenna designs, equipment reviews, and operating practices across different bands. Specific sections are dedicated to CB radio and shortwave listening, broadening its appeal beyond licensed amateurs. The forum's structure supports detailed discussions on operational challenges like the "Work All Postcodes" award, which encourages contacts across UK postal districts. Members can track personal statistics, manage contacts, and engage in challenges, fostering community participation and skill development. The resource provides a centralized hub for sharing knowledge and experiences among radio operators, offering practical insights into diverse radio communication facets. -

The WB5RVZ Genesis Radio G40 build log documents the construction of a 5W QRP 40m SDR transceiver kit, detailing each phase of assembly from power supply to RF filtering. It provides specific component lists, parts placement diagrams, and testing procedures for stages like the local oscillator, Tayloe detector, and RX op-amps. The resource highlights discrepancies between documentation versions and offers practical advice for builders, including a "virtual build" approach to preemptively address potential ambiguities in component identification and placement. It also addresses a specific "VK6IC Fix" for early board revisions, involving trace cuts and jumper wires for improved performance. The build log presents measured voltages and expected current consumption for various stages, such as the 4.9-5.0 Vdc on the 5V rail and under 100mA for RX current. It outlines critical adjustments like image rejection tuning, a common procedure for direct conversion receivers. The resource also includes practical tips for handling components like the 2N3866 transistor and its heatsink, emphasizing pre-assembly. It details the winding of two 1.45 uH toroidal inductors on T50-6 cores with 17 turns of #20 AWG wire, crucial for the RF path. -
