Day 8 (MET): Last opportunity to see the live signal from #Artemis-2 / #Orion with the 20m dish in Bochum. After listening to the #Apollo Missions over 50 years ago, it was a great honor for #SternwarteBochum and #AMSAT-DL to be officially part of the #NASA challenge to provide Doppler measurements.

#AMSAT #QO100 Unfortunately some people are starting to using the NB for LORA transmissions, which exceed the 2.7kHz bandwidth. See below with different spreading factors. ** This is a violation of the NB transponder bandplan, please move to the WB transponder! **

The radio waves from this very distant quasar have been travelling through the universe for 10 billion years before being captured by our SDRs, and correlated between the sites. This is more than twice the age of our solar system!

Die Radiowellen dieses sehr weit entfernten Quasars sind 10 Milliarden Jahre lang durch das Universum gewandert, bevor sie von unseren SDRs empfangen und zwischen den Standorten korreliert wurden. Das ist mehr als doppelt so lang wie das Alter unseres Sonnensystems!
