Satellite Operating Modes
Satellite modes resources for hams worldwide.
Satellite operation offers hams a unique way to make QSOs, often with low power, across vast distances. Operators use a variety of techniques to track and communicate through orbiting repeaters, from simple handheld setups to complex steerable antenna arrays. This mode challenges operators to master Doppler shift compensation and precise antenna pointing to maintain a solid signal during short pass windows.
This category provides resources for tracking satellites, including real-time systems like Heavens Above and Celes Trak for NORAD Two-Line Element Sets. Hams can find homebrew projects for antennas and transceivers, such as the DSP Satellite Transceiver, along with guides for working satellites with common rigs like the ICOM IC-706MKIIG. There are also resources for receiving weather satellite images and information on various digital modes used for satellite activity.

This article describes how to make a quadrifilar helix (QFH) antenna easily, from inexpensive materials: uPVC plumbing pipe and RG-58U co-axial cable. A low-cost, easy-to-build Quadrifilar Helix (QFH) antenna for weather satellite reception using uPVC plumbing pipe and RG-58U coaxial cable. Unlike traditional designs requiring copper pipe and plumbing skills, this approach enables construction with basic tools and minimal technical expertise. The antenna's shorter, wider proportions favor higher elevation angles, reducing interference from horizon-level pager transmitters. Electrical connections are simplified at the antenna's apex, with the coaxial cable forming the radiating elements. Testing demonstrated consistent signal strength throughout satellite passes, proving effective weather satellite reception is achievable without precision engineering to sub-millimeter tolerances. -

The DSP Satellite Transceiver is a conceptual transceiver designed as a dedicated unit for amateur satellite operators. The initial concept was brought about by the lack of satellite functionality on modern amateur radio transceivers, and the specialized requirements of the ham radio operator who utilizes OSCAR amateur satellites. -
Smart homebrew antenna-ELEVATOR system with linear actuator. The actuator is a cheap and heavy tool with high enough torque, ideal for elevation systems, but in practice it needs quite an effort in order to operate correctly in your homebrew antenna system. This page inform you of the actuator's secrets. -

SAT filters ensure effective full-duplex satellite QSOs by mitigating interference between 145 MHz uplink and 435 MHz downlink signals. Custom coaxial and SMD-based filters address transmitter harmonic interference and improve receiver isolation, achieving over 70 dB suppression in the undesired band. Designed for simplicity, these filters maintain optimal VSWR and are housed in shielded brass enclosures. Practical implementations with Yagi antennas demonstrate compatibility with SDR systems, enabling seamless communication even in challenging satellite conditions, such as low-elevation passes and DX pile-ups. -
