1. during the 10:40 utc pass over the delfi-c3 groundstation on thursday 15th of may, the linear transponder was successfully tested and activated for a short time. the cw beacon was received well and subsequently good signals using ssb were received.

an audio file of the test can be found at:

2. we are currently performing tests while the spacecraft is over our groundstation in order to address the downlink dropout issue. since we take it step by step, the satellite may still experience downlink dropouts over the coming days.

3. tle's for object g match best at this moment, we are becoming more and more confident that g is in fact delfi-c3.

4. up to this date, we have received over 130,000 ax.25 frames from all over the world, thank you very much for your efforts and observations so far!

5. delfi-c3 has been given an oscar number by amsat, and is now also known as do-64, which stands for delfi-c3 oscar 64 or dutch oscar 64. it is a true honour for all team members to have delfi-c3 join in the long tradition of oscar satellites.

看過日本一台大電容電動腳踏車... 電容器有一個人的重量, 才幾個 ah 的容量, 耐壓很低, 能量密度遠不及電池... 目前最適宜太空飛行的電池還是鎳鎘或鎳氫, 容易伺候,...
