[Elecraft] Power Supplies

[Richard Fjeld]

Kevin,
I will be interested in anything you find.  I have a RS-50M and I am not 
aware of any noise as you describe.  It may be my hearing.

I do have a line isolator in-line left there from the days when I had a 
G5RV.  That is the only time I have known of RFI.  It was pretty bad.

Dick, n0ce
