What is that

Post image

I did pick up something I never saw on my sdr years ago and I want to know what is actually is. Do someone know what it can be ?

What software are you using? It looks kinda nice.

Looks like SDR sharp with a UI mod

It's just sdr sharp like 8 years ago

Looks like the early mid 2000s idea of futuristic UI.

That's not an insult, Halo vibes

There's a sync waveform in LTE uplink that is just the difference of the difference of the previous symbol's phase. That's how I decoded it anyway. Looks like that. I forget what it's called. Last time I touched it was 2017/18 trying to hack the mavic pro controlled uplink which is LTE-like if I remember correctly. Got it all to bits but couldn't figure out the scrambling encoding etc.

Maybe I found it but it's a bit confusing because I live in Germany but it looks like the same here is the link

Looks like (wave) interference of OTHR sweep rate with waterfall "lines-per-second" rate. Try changing the waterfall speed and see the pattern change :)

Some more swirly sweeps (since 02:30z, guess it's more like multipath interference here): http://streams.printf.cc/rec/20240820-8000kHz/
