This is the usual process:
- Find all the satellites that transmit on similar frequency in SatNOGS DB. This can be done in the transmitters page. Here is a list of satellites that transmit ±65.1KHz:
40320, 41603, 43907, 39431, 40968, 39435, 39439, 39440, 32788, 43156, 39446, 43677, 43679, 43681, 39463, 39087, 52148, 41783, 40377, 27844, 38340, 46276, 43721, 47945, 40012, 40014, 37841, 33493, 41558, 52950, 53463, 49017, 33499, 47964, 28895, 47458, 40931, 43880, 38761, 38763, 39153, 53107, 41460, 49396, 46839, 40056, 39417, 41339, 41340
- Then you can find the TLE sets at the time of the observations. I usually use space-track.org, for example for the 7096731:

- Finally with the TLE list you can use ikhnos and find which of these TLE sets fit the other signal. Have in mind that for fitting exactly at the signal you need to adjust the frequency offset parameter.
