@estima5633 unfortunately there aren’t frequency only observations in SatNOGS.
About IQ, that would be the ideal but it will need a lot of storage, of course you can limit it only when the satellites are in your field of view.
Another solution would be to use STRF for example check the recent thread about it. While it will not give you the opportunity to decode the signals if received, in combination with the time and the frequency will give you a good hint which object is the satellite.
