    I have this frequency for SICRAL 1B. on 11.5° E.


    It is hard for me to tell with the 1.2m dish. It does not look like Comsat's X band TT&C so you are probably right, thanks.


    The earlier plot was without a GPSDO. The one below is with GPSDO so the frequency should be correct now.


    I left it running and noticed that the modulation changed for a while around 18:45GMT. See 2nd plot.


    /edit by qwer: Changed toppic name. Thank you!
