Presents the W9VT Tri-Town Radio Club, an ARRL-affiliated organization serving the Illinois amateur radio community. The club maintains a 2-meter repeater on 147.180 MHz (+600 kHz offset, 107.2 Hz CTCSS) and a 70-centimeter repeater on 444.825 MHz (+5 MHz offset, 107.2 Hz CTCSS), both located in Woodridge, IL. Regular meetings are held on the second Tuesday of each month at 7:00 PM at the Woodridge Public Library, focusing on technical discussions, operating practices, and community service. The club participates in Field Day, supports local public service events, and offers licensing classes for Technician, General, and Extra class examinations. Members engage in various amateur radio activities, including DXing, contesting, and digital modes, fostering skill development among hams. The club's repeater infrastructure provides reliable local communication for members and supports emergency preparedness efforts within DuPage County. Participation in ARRL-sponsored events like the Simulated Emergency Test (SET) and various operating awards promotes active engagement and technical proficiency. The club provides a platform for mentorship, allowing experienced operators to guide newer hams through licensing and operational aspects.

The purpose of this book is to provide a common source for WIRES-X, gather information from manuals, experiences from the Amateur Radio Community, and the best practices from both the Amateur Radio Community and the Bakken Amateur Radio Society. To provide a platform for learning, experimentation, and advancement of Amateur Radio skills and art. A platform of Discovery and to have FUN. To encourage networking, sharing, and exchange of interesting technical information of WIRES X, where people are encouraged to help each other out.

Automated use of EZNEC. AutoEZ is an Excel application that works in conjunction with the EZNEC antenna modeling programs and allows you to use variables to control diverse aspects of the model. You can then run multiple EZNEC test cases while AutoEZ automatically changes one or more variables between runs. Commercial version and free demo available for download.

Evaluates the **LDG Z100 autotuner**, a device designed to automatically match antenna impedance for optimal transmission efficiency. The review discusses its performance in comparison to the MFJ-902, noting that while the Z100 is a reliable autotuner, it does not match the range of impedances that the MFJ-902 can handle. The Z100 is suitable for operators seeking a 100-watt autotuner that covers HF bands, providing a practical solution for those who require automatic tuning without manual adjustments. The review highlights the Z100's operational context, focusing on its use in HF bands and its practical application in amateur radio setups. While it offers a straightforward tuning process, the Z100's limitations in impedance matching are noted, making it less versatile than some competitors. This comparison provides valuable insights for operators considering an upgrade or replacement for their current autotuner. The Z100's performance is positioned within the broader market of autotuners, offering a clear perspective on its strengths and weaknesses in real-world amateur radio operations.
