This is a video demonstration on how you can use VBAudioCable to decode digital HF signals like FT8, SSTV, and more without any radio or an antenna.
It works by sending audio from your speakers to a virtual microphone port. We can tune a webSDR, and play the audio straight into applications like WSFT-X and MMSSTV and more.

VBAudioCable can be downloaded here:
vb-audio.com/Cable

We are using a webSDR to pipe the audio into the software. You can find a HF Radio on this website:
websdr.org

There are many digital ham radio modes you can do this with, so do let me know what fun things you used it for in the comments below.
