Osmocom Source (frequency deviation)

[Artur Nogueira]

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,

Artur
