Over 15 years of continuous operation, Ham365 provides a web-based logging solution for Amateur Radio Operators, allowing them to maintain and share their QSO records online. Originally launched as the online logbook component of Ham Radio Deluxe, it has since evolved into an independent platform, now integrating with numerous other logging applications. The platform shares its database with HRDLOG.net, ensuring that operations performed on one site are reflected on the other, maintaining data consistency for users. Key features include an overview of the latest hour's activity, a display of the most recent QSOs, and a map visualizing recent contacts. It also highlights "Most Wanted" entities and ongoing DXpeditions, providing a dynamic view of current amateur radio activity. The logbook supports various operating modes, including SSB, RTTY, PSK31, and FT8, and handles ADIF data for interoperability. Users can manage their logbooks, track DX activity, and utilize features like OQRS (Online QSL Request System) through its integrated functionalities. The system is designed to be accessible to a wide range of operators, from casual ragchewers to avid DXers and contesters.

This project revisits a minimalist software-defined radio (SDR) receiver built using a Raspberry Pi Pico, now optimized for simplicity and affordability. Designed for breadboard assembly with through-hole components, the receiver covers 0–30MHz, supporting CW, SSB, AM, and FM modes with an OLED display and spectrum scope. Key improvements include enhanced frequency accuracy, reduced op-amp saturation, and lower-cost components. Powered by three AAA batteries, it delivers standalone operation for global signal reception. Ideal for hobbyists, the design fosters experimentation and is documented with firmware and schematics available online.

This is some general information about the lowell amateur radio club!

The Washington County Amateur Radio Club (WCARC) was formally established on June 26, 2014, serving amateur radio operators and enthusiasts in Washington County, Texas. The club provides a local community for hams to gather, share knowledge, and participate in various radio activities. Its formation date indicates a relatively recent establishment within the amateur radio landscape. The WCARC aims to foster interest in amateur radio, offering a welcoming environment for both licensed operators and individuals new to the hobby. Membership is open to anyone with an interest in amateur radio, promoting engagement across different experience levels. The club's activities likely include regular meetings, field operations, and support for emergency communications within the local area.

How to Design and Build a Field Expedient End-Fed Half-Wave Antenna for 20m, 40m and 80m. This Shorty 80m EFHW comprises a 49:1 autotransformer (to match the very high impedance at the end of a half-wave wire), a half-wavelength wire for 40m (also a quarter-wavelength for 80m), a loading coil and a short tail wire. The coil and the short tail wire (about 6 feet) make up the other quarter wave on 80m.

The UniBalun is a PCB for building a lightweight antenna transformer (Balun) or impedance converter (UnUn) for low power radios.

Amateur radio portable operation has a lot to offer, even if you are a shack sloth and have an awesome setup.

Operating within the low-frequency spectrum, transformers serve critical roles in antenna systems, particularly for 160m applications. The resource details the construction and performance of 1:1 transformers built on BN-73-202 cores, emphasizing their use as hybrid combiners or phase inverters for RX antenna arrays. Measurements reveal that these transformers exhibit minimal losses, around 0.12 dB at 1.8 MHz, with variations based on wire type and number of turns. The analysis includes comparative data on transformer performance, highlighting the impact of different winding techniques on frequency response. Notably, the use of coaxial cable for winding improves bandwidth while maintaining low-frequency efficiency. The resource also discusses braid breaker transformers, which minimize inter-winding capacitance, achieving low losses around 0.21 dB at 1.8 MHz. These insights are crucial for optimizing low-band antenna systems, allowing operators to make informed decisions regarding transformer design and implementation.

DXFile is a Windows shareware application designed for amateur radio operators, providing comprehensive log management capabilities. The software, developed in Pascal, facilitates real-time and deferred QSO entry, automatically populating fields like frequency, mode, and DXCC country based on user input and system time. It includes features for searching, modifying, and deleting QSO records, with options to sort logs by date, callsign, or entry order. The program offers various printing functions, including QSL card labels in multiple formats, and can generate standard logbook printouts. Beyond basic logging, DXFile integrates modules for tracking progress towards major operating awards such as DXCC, _IOTA_, WAZ, WAS, DDFM, and DIFM. It provides detailed summaries of contacts by band and mode, including graphical representations of HF traffic. A dedicated QSL Manager module assists in processing received QSLs, allowing users to mark confirmations and print multi-line QSL labels. The application also incorporates a DXCC list viewer, which can be updated to ensure accurate country and zone data for logging and award tracking. A distinctive feature is its HF propagation prediction module, which calculates optimal frequencies and signal levels for paths between **250 km** and **6000 km**, considering both E and F layer ionospheric conditions. This module helps operators determine the best times for long-distance contacts. Additionally, DXFile includes a _Web-Cluster_ interface, enabling connection to various DX cluster servers like DXLITE, DXSCAPE, and NC7J for real-time spot information.
