John, KK4BOB; the whooshing dishwasher noise you describe is coming from your switching power supply---that's exactly what was driving me nuts until I got a linear supply into my system.  The culprit was an Astron switcher but it was almost 15 years old when it started acting up in such a noisy fashion.
 
This is my first posting/email to the digest; hope it gets through properly!

Best regards,
 
Jeff,  NH7RO
