We are ready for HAM RADIO 2026 in Friedrichshafen. You find our booth at A1-771. #amsat #hamradio

Tianwen-2 today again a High Data rate, likely QPSK at 2.048 Mbaud.

Tianwen-2 at #Asteroid (469219) Kamoʻoalewa now transmitting at High Data Rate!! Receiving with the 20m #Bochum antenna on X-Band.

📡Proud to receive this Certificate of Recognition from @NASA ! AMSAT-DL successfully tracked the Orion spacecraft during the Artemis II mission – proving that amateur radio operators can contribute to historic space exploration. Thank you, NASA SCaN! 🌕 #AMSAT #Artemis #HamRadio #Bochum

📌 Οur friends at @freecad.org are launching the first-ever community design contest, in partnership with @labcrafter.co.uk. The 2026 Contest focuses on #OpenScience hardware, inviting participants to design an open hardware pinch valve. Find out more at: blog.freecad.org/2026/05/01/f...

🚀 OSSIE confirmed to fly on the Transporter-18 rideshare mission with SpaceX. ... looking ahead for the ERMINAZ-2 🇩🇪 ride in Space with UARX 🚀🛰

Intruder Satellites on lower end of the 430 MHz UHF Amateur Radio band?

ESCAPADE-Blue on it's way to Mars, now 2.5 Mkm away. 📡〰️〰️🛰️ loud and clear on the 20m Bochum antenna.

FCC gave authorisation to AST SpaceMobile for the next 248 satellites to use the 435 MHz Amateur and Amateur Satellite frequencies for Telemetry & Telecommand (TT&C). docs.fcc.gov/public/attac...

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! **

Artemis-2 Orion Doppler - Day 6 (MET)

The video from Day 3 is now available: www.youtube.com/live/aF1Bmks...

Artemis-II / Orion: Doppler measured versus predicted from last nights pass. The noise on the left side is at AOS.

we had excellent signals from Orion #Artemis-2 throughout the whole night until LOS at 05:18 UTC (07:18 CEST) this morning. First measurement results of measured Doppler compared to predicted trajectory.. everything looks fine!!

Huge Signals from Artemis II, ORION at the Bochum Observatory!

Unfortunately, the Artemis II lunar mission will only be visible in Bochum and across Europe during the night hours.

Fly me to the moon - Sternwarte Bochum und AMSAT-DL verfolgen die bemannte ARTEMIS 2-Mission wie damals das Apollo-Programm der NASA. Mehr dazu in der Pressemitteilung:

In preparation for Artemis II, the Bochum and Dwingeloo radio telescopes, configured as an interferometer, jointly observed quasar J2136+0041 at S-band. (Team: @radiotelescoop.bsky.social @telkamp.eu Bochum Observatory, Peter Gülzow DB2OS)

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!

Im Vorfeld von Artemis II beobachteten die als Interferometer konfigurierten Radioteleskope in Bochum und Dwingeloo gemeinsam den Quasar J2136+0041 im S-Band. (Team: @radiotelescoop.bsky.social @telkamp.eu Sternwarte Bochum, Peter Gülzow DB2OS)

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!

ERMINAZ-2 mission 🛰 one step closer to launch on Falcon 9 Transporter-17 🚀 #AMSAT #PocketQube #hamradio

Lot's of activity with Tianwen-1 today, including high data rate !

Tiannwen-1 is back !!!! 🎉📡〰️🛰️
