How to Install Virtual Audio Cable to SDRuno

SDRuno is a powerful Software Defined Radio application platform designed for use with SDRplay's range of Radio Spectrum Processing receivers. When it comes to decoding WEFAX transmissions using an RSP and SDRuno, there are some crucial steps to follow.

Firstly, ensure that your antenna is placed outdoors and configured in an Inverted delta loop configuration pointed N/E-S/W. This will provide a stable signal reception. Any model RSP can tune WEFAX transmissions, including the RSPduo from SDRplay using its Hi-Z input.

However, users may encounter issues when trying to install Virtual Audio Cable (VB Cable) on their systems. Microsoft's recent changes in the audio chain have caused problems for some users. As a result, it is recommended to set up an insider build and test VB Cable before the upcoming spring Windows update, which could potentially cause more widespread issues.

In this article, we will guide you through the process of installing Virtual Audio Cable to SDRuno. To begin with, make sure that your system is running a current public release version of Windows or an insider build. If you are not already running an insider build, it is advisable to set one up and test VB Cable.

For those who have already installed an insider build, however, they may encounter the 'unspecified sound device' error when selecting the VB Cable output in SDRuno. This issue persists on later insider builds but works correctly with VB Cable on current public release versions of Windows.

To resolve this issue, you can try setting the output of SDRUno to VB Cable using the software defined receiver (SDRPlay RSP2) running SDRPlay's SDRUno software. Ensure that your machine is an i7 desktop with onboard sound, a GT710 graphics card, and 8GB RAM.

In conclusion, installing Virtual Audio Cable to SDRuno requires some specific settings and configurations. By following these steps and using the correct software versions, you can successfully decode WEFAX transmissions using an RSP and SDRuno.
