 first one selects the frequency in the upper spectrum/waterfall. If one wants to listen to a running QSO, one clicks on the left edge of the signal, because it is USB (Upper Sideband).
-Now you go to the lower waterfall and do the fine tuning. Either use the mouse wheel or click in the area around the 0 Hz line to move the frequency.

 Here is an example of a correctly tuned SSB signal. It is in the lower waterfall between the 0 and 3kHz line:

-  * AGC ... increases the volume when speaking softly and decreases the volume when speaking very loudly. The AGC is always recommended, it can also avoid the "Leila" response when speaking very loud for a short time.
+  * AUDIO ... opens a window with settings for the microphone sensitivity (Mic-Boost should be set to 1 at first. Only if the sound is too quiet you can turn it up) and a bass boost. The bass boost is needed for electret microphones which deliver only little bass.
   * MUTE ... reduces the volume in headphones or loudspeaker while transmitting. So you are no longer disturbed by listening back. Quietly one hears oneself for control purposes still.
-  * Compress ... switches the audio voice compressor on/off, 3 compression levels can be selected. The compressor makes the signal louder and more understandable, but it can sound slightly distorted.Especially recommended if you have only a quiet signal.
+  * Compress ... switches the audio speech compressor on/off.
-  * RX and TX filters ... the bandwidth of the audio signal can be set separately for receive and transmit. For SSB QSOs the default setting is: RX = 3.6kHz and TX = 2.7kHz.

+  * TX Bass ... affects the frequency response of the TX audio signal, if enabled, more bass can be heard.
-  * Audio Loop ... The audio signal of the microphone is switched directly to the speaker. This allows to check the correct function of microphone and speaker.

-  * RF Loop ... the Pluto receiver is set to its own transmit frequency. So you receive your own transmission without going over the satellite. With this you can check the function up to the Pluto output. Possibly you have to screw a small antenna to the Pluto RX/TX connectors. But usually it works without an antenna.

+in many cases the default setting is ok. If you want to correct the volume settings, this is done with the volume mixer "pavucontrol". This is installed and can be called by clicking the "MIXER" button.
+In addition to the volume setting, you have comfortable options for assigning audio devices. For example, you can switch the receive signal between the headphones or the speakers in the HDMI monitor without having to change the SETUP of the QO100 transceiver.

+LOCK/FREE ... Switching on and off the automatic beacon synchronization. When using a slow computer like Raspberry 3B+ the beacon synchronization must be switched off (FREE).
