Ok.......so you need a pulse transformer to break up the ground loop.
If you put it on on the RX side, you can use it come up with a differential output to the RX chip.
Newava makes a good one. Pulse Engineering is ok. I do not like the Scientific Conversions models, despite all their hype. Whatever you do, make sure that it is a 1:1 model.

I listened to this advice and obtained excellent results with Newave S22610. Thanks Jocko.
S22083 looks very promising as well.... I haven’t tried it.
I did try S22133 and compared it with S22610. S22133 was noticeable worse.
Make sure no DC goes in to primary winding.
