Virtual Audio Cable Alternative Free: A Cost-Effective Solution for Digital Mode Operations

For those involved in digital mode operations, using a virtual audio cable is crucial to connect their software and rig efficiently. While there are several options available, finding a free alternative can be challenging. In this article, we will explore the concept of virtual audio cables, their importance, and discuss a reliable free alternative.

A virtual audio cable connects the output of one program to the input of another, allowing data to flow seamlessly between them. This setup is particularly useful for digital mode operations like FT8, PSK, and others that require the transmit and receive audio to be sent via wfview. To achieve this, it's essential to create 'virtual audio' connections.

One popular option is Virtual Audio Cable (VAC), a paid software that requires registration and costs $30 for non-commercial use. However, there are free alternatives available, including VB-Cable, which can be downloaded from the official website. While we have not tested VB-Cable yet, it's expected to work similarly to VAC.

For users connected to their rig via LAN/WiFi, virtual audio cables are necessary to facilitate digital mode operations. Fortunately, these cables can be created using various tools and software. For Windows users, Virtual Audio Cable is a reliable option, while for Linux users, similar functionality can be achieved using SoundFlower on MacOS.

To set up virtual audio cables, follow these steps:

1. Connect the output of wfview to the input of WSJT-X.

2. Set the Input device in WSJT-X to 'Line 1 (Virtual Audio Cable)' and Output device to 'Line 2 (Virtual Audio Cable)'.

3. In wfview, set the Audio Output to 'Line 1 (Virtual Audio Cable)' and Audio Input to 'Line 2 (Virtual Audio Cable)'.

4. Ensure the Sample Rate is set to 48000 and BPS Range is set to 16bit.

By following these steps, you can create virtual audio connections using a free alternative like VB-Cable or Virtual Audio Cable. With this setup, you'll be able to connect your digital mode software and rig efficiently, enabling seamless operations in FT8, PSK, and other digital modes.
