W4RNL tutorial on on inductively coupled (link-coupled) antenna tuners

This project outlines the construction of a 3-element reversible quad antenna specifically designed for the 40-meter band. The materials required include pushup towers, pressure-treated posts, insulated wire, and various electrical components such as relays and a balun. The construction process is straightforward, beginning with the installation of the posts in a straight line, followed by the assembly of the antenna elements and their elevation to the desired height. The antenna's design allows for directional signal reception, making it ideal for operators looking to enhance their communication capabilities on the 40-meter band. The project includes detailed instructions on tuning the antenna for optimal performance, ensuring that operators can achieve the lowest SWR possible. Additionally, the design can be adapted for other bands by extrapolating dimensions, providing versatility for amateur radio enthusiasts. Overall, this reversible quad antenna project is suitable for both beginners and experienced operators, offering a practical solution for improving signal strength and directionality in 40-meter communications.

The TU2T DXpedition log provides a critical resource for verifying contacts made during the 2011 operation from _Ivory Coast_. This online tool allows operators to quickly confirm their QSOs, which is essential for QSLing and award applications. Users can typically search by callsign, date, or band to locate specific entries, ensuring accuracy for their personal logbooks. Such online logs are indispensable for DXers pursuing awards like **DXCC**, as they offer immediate confirmation of rare or distant contacts. The ability to verify a QSO without waiting for a physical QSL card significantly streamlines the award application process. This particular log facilitates the confirmation of contacts with the TU2T operation, a highly sought-after entity.

If you're one of the many hams whose principal operating mode is SSB, then the easiest way to increase your enjoyment of the hobby is to use CW. If you disagree with that statement, then there's a good chance, if you're honest with yourself, that the reason is because you have never been good enough at Morse to make using it an enjoyable experience

Collection of modifications notes for the Kenwood TS850

Demonstrates a very fast and effective logbook solution for amateur radio, **HAM-LOG** by HB9CQV, which operates as freeware and supports multiple languages including German and English. This application is designed to be self-running, even from USB devices, making it a portable option for hams on the go. Its database capacity is practically unlimited, capable of handling up to a billion QSOs, a significant advantage for active DXers and contesters. The software offers multi-user networking capabilities and integrates with popular digital mode programs like MixW2, FLDigi, and MMVARI through DDE connections or clipboard/INI-file transfers. It streamlines QSO logging by saving entries directly from these programs and supports import/export via **ADIF** for compatibility with other tools such as MMSSTV. HAM-LOG also connects to DX Atlas and Ham-Cap for enhanced operational awareness. Further enhancing its utility, HAM-LOG includes automatic callsign lookup on QRZ.com and supports eQSL.cc for electronic QSLing. The resource also details two smaller utilities: an Online Callbook DLL for MixW, which automatically populates names from QRZ.com into MixW log entries, and an Online Callbook LookUp command-line tool that writes callsign and name data to an INI-file, both requiring QRZ.com credentials.
