Excited to announce that HydraSDR is sponsoring ph0wn CTF 2026 ! Ph0wn is a one-of-a-kind Capture The Flag event dedicated to hardware & smart device security and it's free for all participants thanks to its sponsors. ph0wn.org #ph0wn #CTF #SDR #InfoSec

Does somebody know if there was an ISS orbit correction, using the latest TLE update from the 23th but we see they are off.

For those that use my Kepler/TLE data, things have changed, please have a look at www.pe0sat.vgnet.nl/satellite/tle/

Per the International Earth Rotation and Reference Systems Service (IERS) Bulletin C, there will be NO leap second introduced at the end of June 2026: hpiers.obspm.fr/iers/bul/bul.... Additional information can be found at: hpiers.obspm.fr/eop-pc/index....

Keep an eye on our website (www.camras.nl) and this account for the official announcement of the CAMRAS-seminar which takes place 14 March. The title is 'Waterstof in je achtertuin', the subject is amateur observing of the neutral hydrogen line. The event will be mainly in Dutch. #savethedate

@hamsatnl.bsky.social We seem to have a signal on 437.725 that matches 66993 (2025-292A). This could be SLIPPERS2SAT because there are no signals on the IARU coordinated frequency. iaru.amsat-uk.org/finished_det...

The #PHASMAmission will run experiments to analyse the spectrum of terrestrial RF transmissions - to quantify global spectrum use, locate potential sources of interference, & detect possible signal transmission violations. @esa.int, @esaconnectivity.esa.int s.libre.space/PHASMA/mission 📷: Exolaunch

@hamsatnl.bsky.social BOTAN has a better match using object 65942. 65943 is a off as can be seen the second image with two curves

📌The SatNOGS Network continues to track satellites from the #Transporter13 launch, generating orbital data for the received #satellites. For more updates, follow: community.libre.space/t/transporte...

📌In Dec 2024, Paul Koetter & LSF's Manthos Papamatthaiou took the stage at the #38C3 in Hamburg, Germany. Sharing the journey of the #SIDLOC experiment & the Curium One #satellite 🛰️ from integration to flying to space successfully on the Ariane 6 maiden flight. 🚀 media.ccc.de/v/38c3-an-op...

With the help of @eelkevisser.bsky.social I was finally able the receive Blue Ghost. A 5 turn LHCP helix on a broomstick into a Nooelec wideband LNA, sysmocom S-band filter, Nooelec downconverter and Airspy R2. Pretty awesome.

News from the #hamradio dept: we managed to make a two-way QSO with Dan HB9Q, through passive reflection off a geostationary satellite, at an altitude of 35.000km. This is a first ever! #wsjtx www.camras.nl/en/blog/2025...

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography

Upcoming satellite launch (2024-12-27) with onboard CASAA-SAT community.libre.space/t/chinese-la...

Wishing everyone a wonderful, healthy and beautiful Christmas and New Year. May the new year bring fun challenges. The first is attached. www.pe0sat.vgnet.nl/download/Hid...
