Great news, Jim! We should always be calling vendors/mfrs to fix problems like this.

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,
