Over 20 years of development have gone into _Shacklog_, a logging software designed for radio amateurs and Shortwave Listeners (SWLs), primarily from the UK. This resource provides a detailed overview of its capabilities, which include real-time and post-event QSO logging, comprehensive log analysis and reporting, and the ability to print QSL labels. It also features a country status display, rig control integration, and supports importing existing logs, along with interfacing with CallBook CD-ROMs for callsign lookups. The software facilitates efficient management of radio contacts, allowing users to track their DXCC status and other awards. Its analytical tools help operators review their operating patterns and contest performance, while the QSL label printing function streamlines the process of confirming contacts. The integration with rig control systems enhances the logging experience by automating data entry, making it a practical tool for both casual logging and competitive contesting.

The 6 Band Inverted L Antenna MK3 is a versatile multiband antenna designed for amateur radio operators. This antenna covers 160m, 80m, 40m, 20m, 15m, and 10m bands, making it suitable for a wide range of HF communications. The design is based on a W3DZZ configuration, incorporating traps for optimal performance. The MK3 version features a sturdy 5/8th CB mast, replacing the original timber mast, which enhances durability against harsh weather conditions. The antenna's construction allows for effective operation, particularly on the 40m band, where it has been successfully used to contact distant locations including ZL, VK, and Antarctica. Constructing this antenna requires careful attention to detail, especially regarding the radials and grounding. The traps resonate at specific frequencies, and additional resources are available for building coaxial traps. The antenna is designed to work efficiently without an ATU on the lower bands, while higher bands may require tuning. This project is ideal for both beginner and intermediate operators looking to enhance their station with a reliable multiband antenna.

The purpose of the APRS-Beacon is to provide simple APRS-compatible position beacons for up to three Objects. It is designed to 'stand alone' and does not monitor other traffic on the frequency. It can use a single-port TNC (in 'native' mode), a single- or dual-port TNC in Kiss mode or the AGW Packet Engine in order to transmit on up to four radio ports.(When running with AGWPE, APRS-Beacon will also work with Windows 2000)

Described is a simple inverted-V antenna which, when used with a balanced ATU, can be used on all the main Radio Amateur HF bands (80, 40, 20, 15 and 10m). The cental support is made in such a way that the wire can be coiled up for storage when the antenna is taken down.

M0VEY shares insights into constructing a 160-meter mobile DX aerial, detailing the process of sourcing materials and assembly. The project began with a goal to avoid a £50 commercial antenna, instead utilizing a £10 reel of _enamelled copper wire_ and salvaged components like alloy tent poles and plastic water pipe. A friend fabricated a custom stainless steel tube for mounting, featuring a 3/8” thread for a mag-mount, enabling secure vehicle attachment. The aerial's design incorporates four alloy tubes, one plastic tube, and a five-foot whip, engineered to split into two pieces for convenient storage. The loading coil, wound with approximately 115 feet of 0.75mm wire onto a plastic former, was then sealed with blue heat shrink. M0VEY reports successful operation, making contacts across the UK and Europe, with the aerial standing about ten feet tall for local nets at 1.972 MHz and taller for the DX window around 1.845 MHz. Future plans include a base-loaded 160m aerial and an 80m version, leveraging components from the existing _160m DX Mobile Aerial_ to maintain a similar overall size with a smaller coil.
