- | ===== About the Antenna ===== | ||
- | |||
- | Since 2024 a "Mini Whip Active Antenna" | ||
- | Planned to be replaced with an Eggbeater antenna in 2025, which has a lower noise floor compared to the Mini Whip, it is located on the side of the building, it's best exposition is along the North South axis. | ||
- | |||
- | The Eggbeater Satellite Antenna has a Ground Plane and is resonant on 70 cm. | ||
- | We have tested it and has proven itself to be a great omnidirectional base station antenna receiving antenna for all Amateur Radio, Broadcast bands and many services. | ||
- | The ground plane elements under the Eggbeater increases the overall upward gain of the antenna, useful for hearing Satellites and the International Space Station. | ||
- | |||
- | ===== About the Diplexer ===== | ||
- | |||
- | DIAMOND MX-62M Diplexer for the ranges between 1.6 MHz and 56 MHz, and between 76MHz and 470 MHz. | ||
- | Allows to connect one antenna to two receivers. | ||
- | |||
- | The diplexer limits the optimal ranges of the SDRs to an overall smaller bandwidth, | ||
- | this limitation can be overcome by bypassing the diplexer for the required time, at the cost of using one SDR at a time. | ||
- | |||
- | ===== About the KiWi SDR SW HF Receiver ===== | ||
- | |||
- | It comes with a GPS Antenna for precise timing. | ||
- | The KiwiSDR is a software-defined radio that attaches to a Seeed BeagleBone Green (BBG) embedded computer. | ||
- | It is a standalone device that allows access through LAN and optionally through the Internet. | ||
- | |||
- | ===== About the OpenWebRX SW running on Raspberry Pi ===== | ||
- | |||
- | OpenWebRX is a multi-user SDR receiver that can be operated from any web browser without the need for any additional client software. | ||
- | Requires a computer, an SDR device and network access. | ||
- | |||
- | OpenWebRX is designed for public shared access. | ||
