Virtual Audio Cable Alternative Free: A Solution for Your Digital Mode Software Needs

As a ham radio operator, you may have encountered the need to connect your digital mode software to your rig's audio output and input in order to use it for transmission and reception. This can be achieved using virtual audio cables, which create a loopback sound card that allows your software to connect to it. However, what if you're looking for an alternative solution that is free?

One such alternative is VB-Cable, a free download that can be used as a virtual audio cable. In this article, we'll explore how to set up and use VB-Cable as an alternative to paid solutions like Virtual Audio Cable.

Firstly, let's understand the concept of virtual audio cables. These are essentially loopback sound cards that allow you to create connections between different audio sources and destinations on your computer. This is necessary in order to connect your digital mode software to your rig's audio output and input for transmission and reception.

To set up VB-Cable, you'll need to follow these steps:

1. Download and install VB-Cable from the official website.

2. Create two 'cables' as per the image below: one for the transmit audio and one for the receive audio.

3. Configure your digital mode software (such as WSJT-X) to use the virtual audio cable as its input and output device.

For example, in WSJT-X, you'll need to set the Input to 'Line 1 (Virtual Audio Cable)' and the Output to 'Line 2 (Virtual Audio Cable)'. Similarly, in wfview, you'll need to set the Audio Output to 'Line 1 (Virtual Audio Cable' and the Audio Input to 'Line 2 (Virtual Audio Cable)'.

It's also important to note that you'll need to ensure that the Sample Rate (SR) is set to 48000 Hz and the BPS Range is set to 16-bit. This will ensure that your audio signals are transmitted and received correctly.

In addition to VB-Cable, there are other alternatives available for Linux users, such as SoundFlower, which can be used on MacOS as well. These solutions work in a similar way to virtual audio cables, allowing you to create connections between different audio sources and destinations on your computer.

VB-Cable is a free alternative solution that can be used as a virtual audio cable for digital mode software like WSJT-X, Fldigi, etc. By following the steps outlined above, you can set up and use VB-Cable to connect your digital mode software to your rig's audio output and input for transmission and reception.
