Regarding my March 25 post about RFI from a Unifi US-8-60w internet 
switch on 10 meters:  The neighbor just called for a test and the big 
noise source is gone.  Apparently his IT guy found a separate power 
source (not sure what, he wasn't in the mood to discuss it).  His switch 
is working and my noise is gone. There are some very low level S-2 noise 
sources that repeat at 16 KHz that I don't remember seeing before, but 
they are not a concern.  Probably from another switcher somewhere.  73,
