The Digirig also lacks any galvanic isolation of the audio or USB data interfaces. It is a compromise designed to be small and portable.
I have had good luck with XGGCOMMS interfaces. They have a bit more isolation built in.

The FT-857 radios are notorious for RFI issues. Make sure you have plenty of ferrites and good grounding. You should probably be using premium cables.
Gaston, the Techprepper on Youtube I believe found some shorter better shielded cables for connecting digirig to an FT-857, if you aren't rolling your own.

Setup was working fine. Then it started failing. With FT8 on WSJTX or Winlink - at some point (I think on end of transmit) the radio would turn off and on again - sometimes repeatedly...
I tried it on two different computers (and RPi and a Windows machine) that had both been recently working (FT8 on 15M was great to Europe from California earlier this week)
"I didn't change a thing" - but perhaps there is some radio setting? or a failure in either the radio or the digirig?
Suspecting RFI - I reset all of the antenna connectors - switched battery - reset all digirig connectors.
