On 25.03.2009, AMSAT-DL sent radio signals from Bochum Observatory to Venus, receiving an echo after nearly 100 million km. This marked Germany’s first planetary radio echo and set a record in amateur radio, surpassing Earth-Moon-Earth reflections by over 100 times. (try subtitle translation on)

Talking about reflections, this is the received echo from Venus of our transmitted S-Band signal (6kW). "HI" message in very slow morse code (.... ..), bounced off Venus. The entire transmission and reception of this morse code took almost two hours. Bochum, March 26th, 2009

There is more radio science on #BGM1 #Firefly_Space than just "Doppler". Below is last nights Doppler curve from Blue Ghost at the 20m dish in Bochum done by Peter Gülzow. From 01:00 to 01:30 UTC you can apparently see the signals from BGM-1 reflected from the surface of the Moon! ⬇️

On Valentine's Day, a student asked the swordmaster: "What shall I give my beloved?" "A sword. It shows you trust them, and trust their abilities." Satisfied, the student left. Another student asked: "I am single, what shall I do?" The swordmaster thought. "Buy yourself a sword. You deserve it."

"Has the old place been invaded?" "If so, they must have regressed- Ah! It's the monkeys!" "Monkeys?" "Walked upright, made stone tools, great painters, you remember?" "Huh. They've been busy." "We left fifty kiloyears ago. Shall we say hi?" "Nah, they must have forgotten us dragons by now."

"What happens to books that nobody reads?" the king asked. "We send them to the archive for safekeeping," the librarian said. "There are many more books in the archive now than we have on the shelves." "That must cost a fortune!" "Not at all. Centuries ago, we found a dragon who hoards books."
