[hpsdr] punched metal backplate for Pandora

[Graham / KE9H]

All:

Since the primary goal is to keep mice out, and the panel does not have to
be structural, I recommend that you consider having the "panel" made out
of printed circuit board material, instead of metal.  Easier for most 
people to
work or drill, if needed, and probably cheaper to make in small volumes.
