It is also possible by running this command from the Raspberry Pi: <code bash> alsamixer </code> {{ :fr:alsamixer.png?nolink |}} To adjust the reception input level (microphone of the USB audio card), let's start to set the potentiometer to 3/4 of its stroke and set the software Mic adjustment // // (CAPTURE) to the high gain position (or maximum). While generating a BF audio signal in the input of your reception, simply by speaking, you're going to decrease (adjust) the level of the Mic channel // // (CAPTURE) until a saturation of the input BF signal is not indicated. To be able to follow these 2 information's you'll need to open two term consoles: the first one dedicated to SvxLink and his tracking, the second one for the software level adjustment with alsamixer utility. <code> Rx1: The squelch is OPEN (4.44352) Rx1: Distorsion detected!
