I have a question about this radio.
If I plug the AC jack in the wall and I have the 12 volt connection hooked
up to a battery as a power failure backup will it damage the radio? Is there
an internal switch to protect it from both sources being connected at the
same time?

I don't know. But I run mine on 12v all the time. The R8B runs extremely cool
if you do that; you can even stack things on it then.
