[Elecraft] Silent power supply for a K3s

[Nate Bargmann]

I have an RM-50M at present.  To cut a lot of the audible hum I have it
setting on some plastic rings that fell out of a light fixture (d'oh!)
and it is thus supported on the bottom plate the transformer mounts to
rather than the feet of the supply.  As I have the supply under the
desk, I just reached over with my foot and by pressing on the top cover
I can cut the audible level considerably more.  I may have to
investigate a fix for this.
