Testing for power supply "hash"
 

I want to see if my new switching supply creates "hash" on any band.

Is it enough to hook up to a dummy load and listen to the difference
between battery power and the power supply in the middle of every band
of interest? Should I disable any controls or automatic adjustments?

What does hash sound like? I have been fortunate not to have
experienced it (to my knowledge).
