Hello guys! long time no speak
These days, our cubesat (Step-1) revived. But we don’t have any transceiver beacuse it is under repare now. so we need to your help.
Could you try to receive our CW signal? we want to check voltage of the battery. CW means STEP1 and then value of voltage.
If you get sound files, Please send to my email.

In most observations (not just mine) I see a CW-like signal from 0 sec to about 200 sec into the recording, starting at about 17-20 KHz then drifting up to beyond 25 KHz. This creates a typical curve in the bottom right in the waterfalls.
I wonder if the TLE for STEP-1 as used by SATNOGS-client is accurate?
We use norad id assigned to step for fetching tle. My wild guess, that needs more investigation, is that this signal is from a satellite in the same path.
We need to check it, by finding which other satellites where deployed at the same time and have transmitters on that frequency.
As it wasn’t only on your observations I think that we can safely say that it is not a terrestrial transmission.
