Thanks to everyone who posted comments.  I need to find out more from the owner regarding charging.... whether he plugs in AC or plugs in a charger.  Regardless, I always assume the problem with ALL electronic charger RFI is noise backing up into house wiring.  In this case it could also be radiating from the van's internal wiring.  If only these chargers would employ adequate filtering like we have in our radio equipment power supplies!  Apparently the charging time is programmable, so if a charge from 10pm to 6am would sufficiently maintain the lithium batteries, it could be a simple solution.  I need more research and information from the mfr/dealer.  The owner is trying to be helpful.

Unfortunately he just completed a large ADU that has multiple noise sources, so I will also be working to get his electrician to substitute analog power supplies wherever possible.

It's nice to know the Tesla chargers apparently don't create RFI, at least in Jim's case.     73, Jim W6YA
