What about a battery with an analog trickle charger?
The analog trickle charger should be RF-quiet.
And wouldn't the battery isolate any PS RFI?

Update to the Spectrum Cable box testing,
What I have tried.
- RF Chokes (Material 31) on power, HDMI & RG6 - DID NOT FIX RFI
- Tightly wrapping the entire box in foil. - DID NOT FIX RFI
- Putting the box on a 12v battery - VIOLA - NO RFI
So now that we know its the power supply, I have to find a 12v 3A wall
wart that is not affected by RFI. Suggestions?
Thanks!
