That wouldn't do anything to stop the RFI.
Some more observations about this incredibly RF-dirty supply:
S9 +40 db on entire 6m band - white noise (not pulsing, not buzzing, just broadband white noise)
S5 or so on HF bands on my 1000D.
I wonder if this is getting into an IF, as it makes no sense that the lower bands are better - unless this really is 50 MHz trash.
Shielded body and ran power output cord through braid - noise went to S9 +10 or so on 6.
Unplug open supply, noise stays until caps inside supply discharge. Remove power cord at supply, same amount of noise until caps discharge.
I'm about ready to bust this thing open and have a look tonight.
Dell is still on my "Duty-list" for this!
