preenfm2 and preenfm3 / USB noise - cheap solution!

I love my PreenFM2.

I had a slight issue with ground loop noise when using usb power; this is reduced, but not eliminated when using the 9v PSU.  However, I found a cheap solution by accident - the noise disappears when the Preen is connected to the PC via an old KVM switch (£5 from Ebay).
