[Elecraft] Noise with KX1 and Powerwerx supply

[Dennis Moore]

I'm using a Powerwerx switching supply I picked up last week, testing it 
out in place of my regular Astron RS-35M to run my K3/P3. So far I 
haven't run into any noise issues with it, seems to be working as well 
as the Astron.

> 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.
