Hi @fredy, I have updated my tle’s and I got slightly newer ones. Then I made a search with rffit and got the expected 4 candidates:
rms limit (kHz): 1
49066 0.511 kHz 435.191058 MHz
49067 0.060 kHz 435.190294 MHz
49068 0.053 kHz 435.190270 MHz
49069 0.048 kHz 435.190248 MHz
Identified 4 candidate(s), best fitting satellite is 49069.
The 49066 is not Ledsat, because it is really different from the other 3. I checked that in the waterfall plot. The other 3 a very close together and have similar small doppler rms errors. It suggests that 49069 is Ledsat, but I think it is too close to call. Maybe @cgbsat has more experience in deciding what is right 
Updated, because there was one bad measurement point.
