I think you'll find that power Schottkys don't have any lower drop than
a typical silicon rectifier. They are not like the Schottky signal
diodes in that regard.

Hi all,
A diode was my first try, but there are several problems with that approach.
The first being the additional volt drop can make battery charging more of a
problem with a fixed supply, though a schottky diode would help to some
degree on that score. The biggest problem was the generation of heat was greater
than would have comfortable with and there was not enough room within the PSU
case to add the additional heat sinking required for the diode. However, the
DC current requirements were rather higher for the repeater application than
would be required to drive a basic K2.
Yes, a diode could certainly be used with care.
