BroadWave Streaming Audio Software facilitates the broadcast of live and pre-recorded audio content over the internet, operating as a server on Windows PCs. It supports streaming from over 40 audio formats, automatically converting files for optimal delivery. The software allows for up to 8 separate live audio streams from a single PC and can serve up to 500 simultaneous listeners, contingent on available internet bandwidth. Listeners access streams directly through standard web browsers, eliminating the need for specialized client software. The free version, available for non-commercial applications, includes most features and does not expire. It supports recording live audio streams to WAV files and displaying the number of connected users. The professional version offers additional capabilities such as custom banner displays and integration with Zulu DJ Software for live mix streaming. System requirements specify Windows 7/8/8.1/10/11, with older versions compatible with earlier Windows OS releases. The application is designed for internet radio broadcasting, podcasting, and sharing live events, providing a direct method for **audio distribution** to a global audience without complex setup.

This resource presents a detailed analysis of the W6NL 2-element 40-meter **Moxon Yagi** antenna, covering its design, construction, and measured performance characteristics. It outlines key specifications such as a free-space gain of 6 dBi, 11 dBi at 70 feet, and a direct 50-ohm feed. The document highlights the antenna's physical attributes, including 52-foot elements, a 27-foot boom, and a weight of 75 pounds, engineered to withstand 125 mph winds. Modeling was performed using **AO6** and K6STI software, with a focus on the unique functions of the transverse tip elements for Moxon coupling, physical balance, efficient capacitive loading, and reduced wind load. The presentation includes comparative data, showing the Moxon's superior front-to-back (F/B) ratio and wider bandwidth compared to traditional loaded Yagis. Performance graphs illustrate the SWR, gain, and F/B across the entire 40-meter band (7.0-7.3 MHz), comparing measured results against calculated values. Azimuth and elevation patterns demonstrate high F/B, with the antenna's pattern matching that of a full-size 3-element Yagi on a 30-foot boom. It also notes a gain difference of 1.5 dB down relative to a K3LR 4-element Yagi on a 50-foot boom, providing practical benchmarks for performance evaluation.
