Operating an amateur radio club, VE2CEV details its activities, including regular meetings and a significant project involving the construction of a **satellite ground station**. The resource outlines the project's inception, team formation, equipment acquisition, and the physical installation of antennas and rotator systems. It specifically mentions the use of a dual-axis AZ/EL rotator and antennas for VHF, UHF, and SHF (2 meters, 70 centimeters, and 13 centimeters), along with the strategic use of **Heliax cables** to minimize RF signal loss. The club also provides information on its interconnected repeater network covering southwestern Montérégie. The content highlights the practical application of the satellite station for communicating via amateur satellites and the International Space Station (ISS). It details the collaborative effort of members in securing a powerful Linux server, negotiating antenna installation with local authorities, and the precise alignment of antennas. The club emphasizes its role in guiding new amateurs, offering demonstrations, and potentially organizing courses, indicating a focus on community engagement and technical education within the amateur radio hobby.

Amateur Packet Reporting System (APRS) operations often require compact, reliable solutions for transmitting position data, particularly for mobile or portable stations. This resource details the construction of the _Tiny Track-I_, a transmit-only APRS tracker designed for straightforward integration with a VHF radio and a Global Positioning System (GPS) receiver. It enables hams to broadcast their location without the complexity of a full-duplex TNC. The project outlines the printed circuit board (PCB) layout and schematic, based on an original design by N6BG, with a personal PCB drawing by SV1BSX. It includes specific component placement and notes an additional 10uF/10V capacitor (C5) for improved IC voltage decoupling, a modification not present in the original N6BG diagram. The unit connects to a computer or GPS via a DB9 female connector. This tracker is ideal for basic position reporting, offering a simple and effective way to participate in APRS networks. Its small footprint makes it suitable for vehicle installations or field deployments where space is limited, providing a **reliable 9600 baud** data stream for location updates.
