5 Band 1/4 wave Telescopic Antenna. The 20m to 10m, antenna is simple and cheap to make, and has a performance that matches commercial antennas but at cost considerably lower. The design was purposely based on a telescoping fibre glass fishing rod as this allows it to be easily stowed away in the car.

Operating a G5RV antenna effectively often raises questions regarding its installation and performance across various bands. This archived discussion from the TowerTalk mailing list captures a real-world exchange, where KI0DZ shares practical insights from her own setup. She details her G5RV strung diagonally between trees, sloping from 25 feet to 10 feet, and notes its use with a Yaesu FT-757's automatic antenna tuner. KI0DZ recounts working 80 meters with 100 watts, achieving contacts up to 1000 miles, and confirms the general requirement for an antenna tuner. The thread also touches upon the G5RV's performance in an inverted V configuration, with a recommended angle of at least 90 degrees, and the ease of building one's own versus purchasing a manufactured version. While not an "antenna expert," KI0DZ's field results and direct experience provide a useful perspective on the G5RV's capabilities for "modest purposes" across multiple bands, offering practical answers to common inquiries about height, configuration, and band coverage.

The **Black Cat CW Keyer** is a macOS application designed for amateur radio operators to transmit Morse code directly from their computer. It provides functionality for typing text to be sent, either immediately or buffered, and allows for the creation and transmission of pre-defined messages via single-key shortcuts. This software addresses the need for a flexible and accessible CW keying solution, particularly for Mac users who might find fewer dedicated ham radio applications compared to other operating systems. It integrates basic text-to-CW conversion, offering a straightforward interface for generating Morse code signals. Operators can utilize the Black Cat CW Keyer for various CW activities, including casual QSOs, contesting, or beacon operation. Its ability to buffer text allows for smoother transmission, while the single-key macro feature streamlines repetitive message sending, such as CQ calls or contest exchanges. While specific comparisons to other CW keying software are not detailed, its macOS focus provides a niche solution for Apple users. The program's utility lies in its direct approach to computer-based CW transmission, making it a practical tool for those seeking a dedicated **CW keyer** on the Macintosh platform.
