Nächste Abzweigung im Rabbithole Amateurfunk: Software Defined Radio. Mit einem RTL-SDR und der Software SDRAngel kann man ADS-B Flugdaten auf 1,09 GHz empfangen.

Testing out plane decoding on macOS. Seems to be pretty busy out there today. #sdr #macos #1090

Die #ISS sendet noch bis Sonntag Bilder in SSTV bei jedem Überflug, das kann man z.B. mit einem handelsüblichen #SDR und einer geeigneten Software (z.B. QSSTV unter Linux) empfangen.
Bonus: Man kann einen Empfangsbericht einreichen und bekommt einen hübschen Award zum Ausdrucken. Mein Junior hat einen bekommen und ist stolz wie Oskar

another interesting use for my #RTLSDR setup: Lightning produces fairly wideband bursts of RF energy, especially down in the VLF to HF frequencies https://ranous.wordpress.com/2017/08/03/diy-lightning-detection-with-sdr/ #SDR #amateurradio #softwaredefinedradio
Seeing some new feeders located in Bulgaria, Texas, Germany… thank you for your feeds, the glutenous drama engine welcomes additional sources of sustenance!
If you would like to feed the Drama engines by harvesting your sky drama with an SDR, check out acarsdrama.com to learn more.
Lots of new feeds in many countries the last few days!
Thanks to the most wonderful people in the world, we now have coverage of mystery galley fluids, broken coffee makers and lavs that won't flush in:
Barvaria, Germany
Winterthur, Switzerland
Dornbirn, Austria
Bangkok, Thailand
Saint-Nazaire, France
Thanks to all these feeders - if you'd like to feed the drama machine, check out https://acarsdrama.com for info!

Vorhin mal wieder einen Überflug von NOAA-19 mit dem SDR und satdump mitgenommen. Man kann recht gut aus den Daten erkennen, dass das Mittelmeer zu warm ist. Die nördlichen Meere sind wegen der geschlossenen Wolkendecke etwas zu kalt dargestellt.
If you’re looking for a quick and easy way to get started feeding the ACARS Drama engine, and lots of other great ADSB, VDLM2 and more projects - check out https://adsb.im.
The project is a single image with support for multiple aggregators, including, as of the new version that just dropped — ACARS Drama!!
Big thanks to the adsb.im crew for including us.

"This blog presents new advanced topics on software defined radio to interested amateurs and professionals. It provides current research topics as well as tutorials and introductory material on selected SDR and signal processing topics."
First time I supervised a master thesis, man I am getting old.
It was extremely fun though to see someone explore #DSP applications and mapping them to a #NPU with great success.
While perhaps no surprise as both use streaming processing, dataflow architectures and #VLIW microarchitectures. It is great to have the NPUs available in modern processors effectively allowing for accelerated #SDR or #DSP on mobile devices.
You can find the work here: https://repository.tudelft.nl/record/uuid:8dc57766-6205-4eb6-a8b2-48550198a9ee
Just got my RTL-SDR and started messing around with it.
Of course, local radio in North Carolina is mostly religious fundamentalism and car sales.
Gotta search for the emergency service frequencies.
How can you use #Python with Software Defined Radios (#SDR)? In this presentation, Patrick shows us his neat project of applying Python to recording radio signals. https://www.youtube.com/watch?v=MonR5zZL-Es
Does anyone know where to find a list with satellites and frequencies? I'm looking for std-c data from Inmarsat 4-f2
Boost welcome :)

I use Zello to link audio received on multiple SDR radios at home to my phone when I'm out and about.
Channels on the SDRs are fed via virtual audio cables to the Voicemeeter audio mixer, which has a remote macro addon which I use to prioritise some channels over others by having one channel mute others if they're active together. The mixer output is fed to Zello and Zello uses "vox" mode to key the "transmitter".
On 25th June Zello pulled support for the older free Zello PC app I used, and the service stopped working. Thank fully there's a workaround, as Zello are continuing free use for Friends and Family using the mobile app.
By running Zello mobile on the Bluestacks Android emulator in Windows, I can continue to use the facility. Happy days!
tried creating an image (using #chatGPT) of a concept Software Defined Radio using #RaspberryPi, #RTLSDR in custom casing, knobs, keyboard & screen running #SDR Software. I need to improve the prompt to be more detailed. #amateurradio #hamradio #AI #GenAI
Heute habe ich versucht mit einer L-Band Antenne Daten von Inmarsat GX5 zu empfangen. Leider hat das ganze nicht so wirklich geklappt. Gearbeitet habe ich mit satdump-ui und habe auch „etwas“ gesehen, aber konnte nichts decoden.
Kann ich irgendwo passende Neigungswinkel und Frequenzen für Satelliten nachschlagen? Ich glaube ich mache da noch etwas falsch. Die Sicht auf den Satelliten war aus meiner Sicht frei.
