My $1200 Pioneer P9 does not power with antenna with radio only .

My Sony did .

Anyway I complained to Pioneer and they told me it requires tapping into the Logic circuit if you have a single button that rotates between sources. If your radio has a separate button for CD, Radio, etc., you can try tapping at the switch. If you run off the power of the tuner it may create noise issues. You need some form of isolation.

So the easy thing to do is add an external switch on the antenna wire .
