BTW, know what the power supply on a Microtrack is?
Switchmode.

How could it possibly be anything else?

Laptop supplies usually have ground connected usually causing ground loops.
Switchmode supplies are typically better at isolating 60Hz feedthrough..

Laptop supplies are usually the worst possible switchmode devices, and spew
huge amounts of high frequency junk on both their inputs and outputs. And
plenty of RFI too!
