I have uSDX black radio. I did some QSO but during transmission my signal is not very clear. I know this radio has some settings and I really do not know , what should I change?

You can try lowering the audio level from Digirig. On the radio you can see if there is mic gain setting you can adjust.

You can monitor Digirig’s audio output by plugging regular headphones into audio socket. The tones will be heard on the right side.
