Re: Osmocom Source (frequency deviation)

Artur,

You haven't mentioned what software you are using, how you have it configured, or what your flowgraph looks like.

If you are using two SDRs and the frequency difference is a few kHz, then that is just oscillator differences.

Hi everyone,

I'm comparing the spectra of a pair of transmitted/received GMSK signals (carrier frequency = 923 MHz).

As expected, there is a certain channel attenuation.

Nevertheless, there is this frequency deviation at the Osmocom Source output:

I suppose this is something related to the receiver hardware.

Do you have a suggestion on how to compensate for this effect at a software level?

Best regards,
