Sound card: ASUS Xonar Essence STX

The heart of G11 SDR Transceiver is without any doubt the sound card. The better the card, the better the performance. My choice of sound card is ASUS Xonar Essence STX, which comes as PCI-E x1.

STX is available online for under $200.

The installation is very much straight forward - just follow the included instructions.

The card comes with an adapter lead to convert two RCA outputs into 3.5mm stereo output. The input is LINE IN is 6.3mm socket.

After the installation set the STX as your default Windows sound device.

Open the Xonar Essence Audio Center and set parameters as shown below.

Make sure not to enable any sound effects!

Set the volume.

This is pretty much it. Your PC is now ready for installation of GSDR software.
