This may need re-stating. The reverse polarity protection goes IN THE
RADIO, not the power supply. Right fellas?

I'm not understanding something here. You want to design a power supply
that
protects against reverse voltage and overvoltage. OK. Is this power
supply a
battery or are you actually building a power supply that runs from the
wall
outlet?

The requirements are quite different, depending on what you are trying to
achieve.
