Facilitates efficient logging of amateur radio contacts, offering a robust solution for hams managing their station activities. The software integrates _CAT control_ capabilities, allowing direct interfacing with popular transceivers from manufacturers like Yaesu, Icom, and Kenwood. This feature streamlines the logging process by automatically capturing frequency, mode, and other QSO details directly from the radio, reducing manual entry errors and improving operational efficiency during contests or DXing. _HAM-LCT_ includes a comprehensive database, enabling users to store and retrieve contact information, QSL data, and other relevant details for each QSO. The program supports various operating modes and provides tools for searching and filtering log entries, which is beneficial for award tracking and station analysis. Its design focuses on providing a user-friendly interface for everyday logging tasks. While the original author, _HB9CQV_, has discontinued development of HAM-LCT in favor of a newer logging application, this version remains available as a functional freeware option for Windows users seeking a dedicated logbook with integrated rig control.

One common challenge in antenna systems is mitigating common-mode current on the feedline, which can distort radiation patterns and introduce RF in the shack. This project details a 1:1 balun design that ingeniously avoids traditional ferrite beads, often a costly component, by substituting them with steel wool. The steel wool, when integrated into the balun's construction, effectively attenuates unwanted RF on the outer braid of the coaxial cable, ensuring that the antenna radiates efficiently and as intended. The construction involves winding coaxial cable through a PVC former, with the steel wool strategically placed to provide the necessary common-mode impedance. This method offers a practical and economical alternative for hams looking to build effective baluns without the expense or availability issues associated with ferrite cores. The design principles focus on creating a balanced feed to the antenna, crucial for optimal performance of dipoles and other balanced radiators. Experimentation with such designs can lead to improved field results, particularly for those operating with limited budgets or seeking innovative solutions for their antenna systems. The simplicity of using readily available materials like steel wool makes this a compelling build for many radio amateurs.

The Radio Attic serves as a dedicated online marketplace for **antique radios**, offering a platform for enthusiasts to buy and sell vintage communication equipment. The site features classified advertisements, each displaying full-color photographs of the radio, a detailed description, and a direct link to the seller's email address. This structure facilitates direct communication between buyers and sellers, as transactions are handled independently, not by the webmaster. Listings are categorized by style, manufacturer, and year of manufacture, including models from Admiral, Airline, Atwater Kent, Crosley, Emerson, Fada, General Electric, Philco, RCA, Silvertone, and Zenith. The platform also tracks new additions, with 49 radios and 6 books added in the past 30 days, and highlights recently sold items, totaling 157 radios this year. Beyond sales, the site provides resources like a price guide and information on upcoming swap meets, such as the Southeastern Antique Radio Society's Spring Swap Meet in Forsyth County.
