The _Fuji-OSCAR 20_ (FO-20) amateur radio satellite, launched over six years prior, continues to operate reliably, despite a gradual decrease in its Nickel-Cadmium storage battery capacity and solar cell degradation. The satellite's power system can still supply approximately **10 W**, enabling operations. During the non-eclipse period, typically from mid-June through March, the satellite experiences a 0% eclipse rate, ensuring sufficient power generation. This allows for the potential operation of the onboard BBS, which had been previously suspended due to concerns about power shortages. An "eclipse rate" refers to the proportion of time a satellite spends in the Earth's shadow during each orbit. When the satellite's orbital plane is perpendicular to the sun's direction, the eclipse ratio becomes zero, meaning continuous solar illumination. Understanding these eclipse periods is crucial for managing satellite power budgets and scheduling operations, particularly for power-intensive functions like the BBS, which can now be considered for activation during periods of sustained solar exposure. -

The Noantri WebCLX presents real-time DX spots, including frequency, DX callsign, country, and comments, facilitating active DXing and contesting. It operates as a web-based cluster, offering an alternative to traditional Telnet clusters for accessing spotting data. The interface displays current UTC, allowing operators to track propagation and activity across various amateur bands. This service is maintained by the _Noantri DX Group ARI Roma_, indicating its origin within the Italian amateur radio community. It supports the dynamic exchange of DX information, crucial for operators seeking new entities or participating in competitive events. Key features include the display of spots for modes like FT8, and it functions as a DXSpider-based system, providing a robust platform for **DX spotting** and **propagation analysis**. -
