Osmocom use

[ikibalamRF]

Have you read the HackRF documentation?

no

What outcome were you hoping for?

transmit and receive a cosine using hackrf one and using the block osmocom

What outcome actually happened?

In the receiver I try to demodulate but I don't know how the osmocom block works. At the receiver I am multiplying by a cosine to demodulate and using a low pass filter to recover the original signal which is a cosine but the signal appears to still be modulated

What operating systems are you seeing the problem on?

windows 11

What is the output of hackrf_info?

Are you using any third-party software?

GNU RADIO

Are you using any third-party hardware?

antenna

Multiplying by a cosine doesn't demodulate a signal, it just shifts the frequency.
Can you explain a bit more about what sort of signal you're working with and what you want to do with it?

@ikibalamRF Judging from your comment, it seems that you're trying to demodulate an AM signal.
Yes, by multiplying and filtering is possible to demodulate a receiving AM signal. But that will only happen successfully if your LO is matched with the carrier frequency of the transmitted signal, and I think that's were your problem resides.
