Hello,

I’m using GNU Radio companion to try to receive a satellite signal in S  
band.  
As I have read with a doppler shift will be around ~60kHz. This will  
affect both the carrier frequency as well as the baseband signal.

I’m trying to set the parameters of the PSK demod (Frequency BW, time  
BW, phase BW) to correct the doppler. Right know they are set to 62.8m.  
I have been trying to find information about how to configurate this  
parameters but I can’t find information anywhere.

Thank you
