The Quadrifilar Helical antenna provides circular polarization and complete hemispherical reception, which is precisely what is needed to receive the polar orbiting weather satellites, and as a 2 meter antenna it will receive horizontal, vertical and clockwise circular polarization.

A checklists of amateur (ham) radio satellites, including launch dates and images of the satellites.

This project is a portable device used to automatically point a directional antenna towards an orbiting satellite. It takes all the effort out of little kids holding the antenna and figuring out where to point it. It allows students to talk through Amateur Radio satellites or download weather satellite images. Note: This is a complex DIY project for the advanced kit constructor.

History of all OSCAR satellites from 1961 till today in chronological order.

This antenna was conceived mainly for high-speed digital transmission via satellite. The antenna is made of two full waves loops , mounted at right angles to each other. Then coupled together, 90 degrees out of phase over a horizontal circular reflector. With this configuration the antenna is omni directional and circularly polarized.

OpenHamClock is a modern, open-source dashboard for amateur radio operators, designed as a web-based successor to the original HamClock. Deployable locally on a Raspberry Pi or via the cloud, it centralizes essential DX operations into a single, intuitive interface. At its core is an interactive world map that visualizes real-time DX spots, signal paths, satellite tracking, and POTA activators. The software seamlessly integrates critical tools like WSJT-X, DX Cluster, and PSKReporter for monitoring digital traffic. Additionally, it provides vital environmental data, including real-time space weather indices, solar activity, and personalized HF propagation predictions. With customizable themes and a modular architecture, OpenHamClock offers modern operators comprehensive, at-a-glance situational awareness of global radio conditions

Before the advent of satellite communication, maritime communication adhered to an international protocol requiring ships and coastal stations to observe silent periods twice an hour, reserved specifically for emergencies. These silent periods were marked by red sectors on the 500 kHz frequency and green sectors on the 2182 kHz frequency. The 4-second red bars facilitated the manual transmission of the SOLAS distress signal.
