[RFI] 48v DC Clean Power Supply

[Jim McCook]

Chuck,

I hear no sign of this noise anywhere on 80m.... or even up in the SSB 
portion.  Definitely nothing on 3.588 or nearby.

I just rechecked my own noise from this device that we confirmed by 
powering down the switch:

28.060
28.310
28.556

These are approximate frequencies.  The noise is about 10 KHz wide and 
looks like a hill, not a peak.  It's S-9 at 100ft away on 28.060 and a 
bit weaker on the others.  Frequencies vary constantly over several 
KHz.  I just realized there is a repeating interval at 250 KHz.  I 
wonder if you see the noise on 10m?

Today I find no sign of it on 15m or any other HF bands.
