Quelle soirée extraordinaire hier grâce à @ericlagadec.bsky.social et @guillaumemeurice.bsky.social à Rouillac (16) ! De l'ambiance ! Scientifique et apolitique comme il faut 😂 Merci ! ainsi qu'à Marion, Nathalie, Adrien et Ulysse malgré eux.

Chang'e-3 transmitted today for over 5.5 hours from Mare Imbrium, when Sun's elevation as seen by Chang'e-3 on the #Moon for its current illuminated period reached ~25°. Spectrum waterfall shows command station sweep and lock. AOS in Bochum at 12:50 UTC, LOS (transmitter off) at 18:08 UTC.

Hope to meet you in few days at fosdem.org/2026/schedul... Talk about #plutosdr clones and firmware.

My friend Pascal F6HCM is spending so good time over French Polynesia islands ! 🥥 ☀️🤿 Anyway he took a QRP transceiver with him. Active as FO/F6HCM on 15 mtrs band 21030-21040 CW (15-20 WPM) usually around 1600-1800 UTC and 0200-0400 UTC. Not every day, when possible. Good luck ! #hamradio #DX

Après 120 ans, la fin du Coupon Réponse International (IRC).

Énième rappel : en cas d'évacuation d'urgence d'un avion, ON NE PREND PAS ses bagages, il s'agit d'une question de vie ou de mort, ni plus ni moins.

Amateur Radio (DATV) An experiment using a digital TV mode has been carried out on the 10m band between Belgium and Greece, using a bandwidth of only 150kHz. EI7GL reports on his blog page: https://ei7gl.blogspot.com/2025/11/digital-amateur-tv-experiment-between.html #amateurradio #datv

Glad to see someone mentioning DragonOS on BS ! I'm using DragonOS on my machines since years, even my customers are falling in love for DragonOS 😅 With tens of pre-installed SDR applications, nothing to do once installed, except playing with your SDR devices. Brilliant CemaXecuter! #hamradio

Ooohh ! #GRAVES forever.

Début 2025, un gigantesque incendie a ravagé plus de la moitié de l’île Amsterdam. De retour sur place plusieurs mois après, des scientifiques tentent d’en estimer les conséquences sur ce havre de biodiversité à la croisée de l’océan Indien et de l’Antarctique.

J'ai reçu le certificat pour la 'SSTV Series 30' 😀 D'habitude je ne fais pas la demande, mais la session a été si courte que ça valait le coup d'avoir ce collector. Cerise sur le gâteau mon 'heroe cosmonaut' Sergueï Krikaliov est en bonne place. Thanks @arissintl.bsky.social ! #ISS #hamradio #SSTV

25 years ago this week the ISS Expedition 1 crew activated their first educational payload. Amateur Radio on the International Space Station went on the air with two test contacts! Our STEM mission continues to serve students and life long learners around the globe!

Received first image from the serie 30 , nr 11/12. As usual using a Baofeng. Low elevation 17 deg, under the trees, so not so bad. #ISS #SSTV #ARISS

Et une petite pensée pour Enzo, le vrai, qui justement suit ENSO de près 😂 Joli la boulette !

Becoming addict to #ISS live stream provided by SEN. The foot page dashboard is really useful. And sound ON Moreover an excellent geography learning experience ! 👍 www.youtube.com/watch?v=fO9e...

Today we are proud to have supported the return of live HAM-TV video from the ESA Columbus module on board the International Space Station during an ARISS school contact in the UK. 📡🚀👨‍🚀

got pictures #6 #7 at 11:25UTC pass and vigorous shower (rain) at the same time. #ISS #SSTV #hamradio

As usual, a simple Baofeng with the stock antenna is enough to make you happy. #ISS #SSTV

A false colour crop of the Iberian peninsula from a Fengyun 3F pass @ 10:55 UTC. Absolutely shocking to see how big the burnt areas from the recent wildfires are !

Quiet place just for a minute : inside the eye of hurricane

EOL for satellites NOAA-15 (Aug 12) and NOAA-19 (Aug 19). For years, these 2, and recently decommissioned NOAA-18, were staples for amateur radio enthusiasts with a passion for weather. What's next? vu3dxr.in/the-end-of-n... @armelcastellan.bsky.social @ensembleator.bsky.social @spann.bsky.social

This morning, somewhere in a lost place of West Africa, testing (double) portable setup for cubesats link. Amazing experience, got the expected signal, but not #hamradio.

A lire en entier pour les explications 👍

HamTV (DATV) transmitter is still active now over Europe. Just a single carrier at this moment. live.ariss.org/hamtv/ #hamradio

HamTV Acquisition of Signal (AOS) reports! Thanks to several European hams for confirming the HamTV carrier transmissions earlier today. Several North American passes upcoming, so we'll watch for those reports too.

Tous sans exception, avec un bagage à mains, contrairement aux consignes d'évacuation. Décidément ça devient une habitude.

... this time, Space Force made a typo, and instead of 64786's orbit being a copy of 48274 Tianhe, it's a copy of 48724, a debris object from a NOAA satellite in an entirely different, polar, orbit! So, TLE users, please ignore data for 64786 until this is fixed.

Here is the thing. Amateurs figure out how to get satellite data needed for hurricane forecasts after the US administration decided to turn off the supply www.theregister.com/2025/07/21/s...

Il nostro (mio e di @aang23.satdump.org ) lavoro di decodifica di SSMIS, strumento essenziale per rilevare e caratterizzare gli uragani, ma interrotto per motivi politici, ha attirato l'attenzione del Register che ha dedicato un articolo al nostro #SatDump! www.theregister.com/2025/07/21/s...

Souvenir de Roger Gicquel avec son non-sourire habituel (sic) annonçant qu'il n'y a pas de petits hommes verts sur Mars 😅

🛰 Un télescope ça sert pas que à faire des belles photos. On peut aussi observer (et surveiller) des satellites avec 😋 La nuit dernière, j'ai filmé pendant 5h le groupe de satellites de télécommunications ASTRA 19.2°E, dans l'arc géostationnaire telescopius.com/pictures/vie...

CyberChef is one of my favorite online tool to parse, convert, encrypt or decrypt data. gchq.github.io/CyberChef/

Demodulating MTG-I1 raw data @ 26Ghz received in Panska Ves. It is 188M OQPSK 1/2 and RS I=5. Unfortunately, it is encrapted. It's very disappointing considering it's supposed to be public life-saving data... S-Band is not encrypted.
