Hi Peter,

Maybe, yes. But i wouldn't expect it.

The timing is accurate!
pi@Raspi1 ~ $ sudo ntpdate ptbtime1.ptb.de
7 Jul 21:18:29 ntpdate[3404]: adjust time server 192.53.103.108 offset 0.001204 sec

Is the signal near 18.2 kHz in the plot that you sent a local signal? VTX?

That's from the "RDL-Chain" at 18.2 kHz.
According to Stefan's spectrogram VTX transmits
at 17 kHz currently.

@Stefan:
1.
There's a signal visible at 23 kHz which should be
at 25 kHz. Maybe a "Nyquist-mirror" ?
2.
Timing seems to be way off on the RPi over there.
