Presents a construction project for a 1:1 current balun, specifically detailing the _Sorbie Balun and Bottle Choke_ design. The resource outlines the winding technique, employing 4+4 turns of mini coaxial cable on a large ferrite core, and provides insights into the physical assembly. It includes specific material recommendations, such as the type of ferrite and coaxial cable, crucial for achieving the desired impedance transformation and common-mode current suppression. The content covers the practical steps involved in building the balun, from preparing the coaxial cable to securing the windings on the ferrite toroid. It also discusses the integration of the balun into an antenna system, emphasizing its role in maintaining pattern integrity and reducing RF interference in the shack. The resource offers a clear, step-by-step approach, making the project accessible for homebrewers. Illustrations and photographs accompany the text, visually guiding the builder through each stage of construction. The article concludes with performance expectations and considerations for deployment, ensuring the constructed balun functions effectively across the intended frequency range. -
The m0xpd keyer project utilizes a PIC16F628A microcontroller, offering Iambic A and B modes, adjustable speed from 5 to 40 WPM, and variable weight control. It incorporates a sidetone generator with adjustable frequency and volume, along with a PTT output for transceiver control. The design includes a 16-pin DIL IC socket for the PIC, a 3.5mm stereo jack for the paddle, and a 3.5mm mono jack for the PTT output. Powering the keyer requires a 9V DC supply, which is regulated down to 5V for the PIC. The circuit board layout is designed for through-hole components, facilitating home construction. A detailed schematic and a parts list are provided, guiding builders through the assembly process. The project also discusses the firmware programming for the PIC16F628A, essential for the keyer's functionality. Construction details cover component placement and wiring, ensuring proper operation. The keyer's compact size makes it suitable for portable or shack use, providing a reliable CW interface. -

Operating as a local amateur radio club, the Wireless Association of South Hills (WASH) provides a community hub for hams in the Pittsburgh, PA area, identified by the N3SH callsign. The club engages in a range of activities including the Annual Field Day, the PA QSO Party, and a 2 Meter Contest, fostering participation in various aspects of the hobby. WASH also supports local ARES/RACES efforts, highlighting the critical role of amateur radio in emergency communications during disasters, and facilitates ARRL/VEC exam sessions for new licensees. Beyond contests and emergency preparedness, WASH hosts club picnics and an annual hamfest, promoting social interaction among members. The club maintains VHF/UHF repeaters, which are essential for local communication and extending range for members. Regular activities include a Monday evening WASH NET at 8:00 PM, providing a consistent on-air gathering point. The club's focus on both recreational and public service aspects of amateur radio, from making new friends to providing vital disaster communications, underscores its comprehensive approach to the hobby. -
