Observation 443303: ISS (25544)

#1

Regarding Observation 443303 …
Any ideas what the signal at -20 Khz at the start of the recording is

#2

Also where would the rest of the conversation have been recorded

#3

Given that this signal is not visible to other observations of the same pass, it is a terrestrial signal.

You can find more details about this recording/pass at this thread.

Thanks I have been trying to grab just that section of audio but I guess its lost from the ogg and the RAW IQ won’t be saved on the pi?
Thanks for the pointer to the other thread very excited to listen to this :slight_smile:

Indeed the ogg is limited around the centered frequency and the IQ is by default disabled.
