Good evening Jshua,
Thank you for your answer, that helped me a bit. I adjusted the TX and RX gain on the bottom left of the screen.
So now the TX signal works, I can also see the Rx signal in the waterfall, but only weakly.
I have to feed it with an HF signal from the S9+ so that it looks normal and also decodes it.
As already mentioned, FT8 works perfectly.
So I think it's due to the level setting in the mic input of the Raspberry pi/FLDigi software.
I use KMix as control software, here the volume is set to 100%.
I'll probably have to install another software with which I can also make microphone amplification.
What do you think about?
Thanks in advance for your answer.
