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.
Panoradio SDR | Advanced Software Defined Radio
https://panoradio-sdr.de/
"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 :)
This seems to be digital, using large bandwidth.
Probably 2G cellular?
The HackRF One came out a decade ago, but there's finally a major hardware uprev. The HackRF Pro. #electronics #sdr https://greatscottgadgets.com/hackrf/pro/
Radio Software
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
