Amateur radio operators frequently seek efficient methods for logging contacts, particularly during contests or DXing sessions where speed and accuracy are paramount. MiniLogBook addresses this need by providing a streamlined logging utility designed for Windows environments. The software facilitates rapid entry of QSO data, offering an automated lookup feature for previous contacts based on recent callsigns, which significantly reduces redundant data entry. The application's distinctive utility lies in its integration capabilities with other ham radio software, specifically _MRP40_. Users can select text within the MRP40 receive window and, with a double-click, automatically insert that text into MiniLogBook. This feature is particularly advantageous for operators engaged in digital modes like RTTY or PSK, where copying callsigns and exchange information accurately and quickly is critical. The tool aims to simplify the logging workflow, allowing operators to focus more on the contact itself rather than manual data transcription. While primarily a logging tool, its focus on quick entry and interoperability with specific third-party software distinguishes it from more feature-rich logging suites. The software is distributed as freeware by _Polar Electric_, making it accessible without cost. Its small footprint and direct functionality cater to operators who prefer a minimalist approach to logging, prioritizing efficiency over extensive database management or advanced reporting features.

URLog, version 0.1.10, functions as a freeware amateur radio logging application designed for basic QSO record-keeping. The software provides core functionalities for inputting contact details, including callsign, date, time, frequency, and mode, which are fundamental for maintaining an amateur radio logbook. Its design emphasizes ease of use, making it accessible for operators who require straightforward logging capabilities without extensive advanced features. The application's utility lies in its simplicity for everyday logging tasks, particularly for those who prefer a local software solution over web-based loggers. While specific data formats supported are not detailed, standard logging practices suggest ADIF compatibility for export, facilitating integration with other ham radio software or online logbooks. The software's compact download size of approximately 4.5 MB indicates a lean installation, minimizing system resource usage.

The resource presents a mobile antenna mast mount designed for rapid deployment from a vehicle's trailer hitch, addressing specific design criteria for portability and ease of use. It outlines seven key design goals, including fitting inside a vehicle, handling various mast diameters, and enabling one-person setup without tools. The construction utilizes offset T-handled stainless bolts for tool-free mast securing and a "tab" mechanism to prevent collar slippage. Detailed deployment instructions are provided, covering steps from attaching the bottom collar to securing the mount in the hitch, erecting the mast, and tightening both collars. The author, K0EMT, reflects on potential improvements, such as welding the bottom collar for enhanced stability versus transportability. The project also credits AA0ZC for the physical construction.

An Halo antenna for the six meters band in French

A 6 dB gain Moxon rectangle antenna, designed for the 2-meter band, offers an excellent solution for hams seeking a compact, directional antenna for **SSB** operation, particularly in restricted spaces like an attic. This design emphasizes ease of construction using readily available materials such as 4mm OD brass tubing and plywood, making it an accessible project for many radio amateurs. The antenna's inherent characteristics, including a high front-to-back ratio of 37 dB and a 50-ohm feed impedance, contribute to its effectiveness in mitigating local noise and focusing radiated power. The project leverages the free MoxGen program for precise dimension calculations based on the desired frequency and wire size, and utilizes 4nec2 for pattern analysis, confirming a 3 dB beamwidth of 80 degrees. Construction involves bending brass tubing for the driven and passive elements, mounting them on an 800 x 350 mm plywood boom, and securing them with cable clips and epoxy resin. Initial SWR measurements at 144.3 MHz showed 1.6:1, which improved to 1.3:1 at 145.3 MHz across a flat band from 144.1 MHz to 145.5 MHz after adding a **coaxial choke** to mitigate common mode current.
