Is there a frequency error somewhere?
I think there is signal from the sat about -25 kHz in the waterfall.
Or do you have some other explenation?

It is the signal of GRBALPHA from the same launch at 437.025 MHz.
OK, seems reasonable. So would you say that CubeSX is not transmitting at all or is my receiver bad?
Not at all, you can see CubeSX-Sirius-HSE in the middle starting around 240s. GRBAPLHA is the signal at the left.
The waterfall has dynamically generated power scale depended on the power of signals/noise that receives. So in this case, there is a low pass that receives GRBALPHA which has strong signal in comparison with CubeSX-Sirius-HSE but you still be able to see CubeSX-Sirius-HSE. That makes it a very good reception.
OK, now that u say it i see it too. Thanks for enlighten me.
