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.

Thanks for the information, please check again, object 67684U 1998-067YA seems a better match.
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
I guess a type and needs to be SPNeX
The Slipper2sat team shared that this signal is most likely from Egyptian 6U satellite SPNIX. They also would like to hear from the community if we do receive GMSK 4k8 signals on 437.375
@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...
This is the PHASMA-LAMARR of the Libre Space Foundation's #PHASMAmission
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.

The GMSK signals are at +/- 437.375
@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...
On the assumption that AIAinSat is using 400.650 MHz (some confirmation would help) it is following 62688. If BLUEBON is indeed using 400.850 (again we need confirmation) there where no signals detected in a 24 hour window.
📌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. 🚀

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.
tinyGTC being developed youtu.be/v3Kyu8TlOcs?... I hope the translation will do a good job.
Screenshot of WSJT-X with the details of the QSO
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

This image shows the hourglass shape of the nights shortening and lengthening from winter to summer and from summer to winter, passing clouds, the Moon passing through the night sky every month (diagonal bands) and the Sun climbing higher in the sky during summer.
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

Sorry to hear, but the launch failed.
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...
