Signal analysis of 433.92 MHz signal with Universal Radio Hacker

Sub-GHz
#1

Hi,

I am trying to record and replay a rather simple signal with Flipper Zero. It does not work, however, neither with the AM nor FM options.

Next, I recorded the signal with RTL SDR and Universal Radio Hacker. To me it seems like this is a PSK modulation, which probably explains why Flipper cannot record or replay the signal properly.

Can anybody have a look at the attached record and let me know what can be done to replay this on a Flipper?

Thank you a lot!

PS: This is how the raw signal looks like

FM deviation can be determined in sdrsharp, half the width between the peaks

Okay, so you think this is FM and not PSK? I am not very experienced with interpreting the raw signal yet. Since Flipper was unable to read any FM protocol, I assumed it would be something else.

I think FM. What exactly are you reading, photos?
