[hpsdr] Munin Enclosure

[Dick Faust]

I have not built my Munin as yet, but even though the Pandora enclosure 
is aluminum the paint will surely affect the heat transfer. I think 
cutting a hole for the heat sink and using an aluminum angle brackets to 
support and attach would be better. If you have placed a fan inside to 
blow across heatsink there may be enough ventilation to work.

As a side note I have put up some of Kjells Testing information on the 
Munin site today.
