[hpsdr] Munin Enclosure

[Kjell Karlsen]

Hi All.

I agree with Helmut.

But if you cut a hole in Pandora for the copper spreader and install it  
directly to the outside heat sink, the heat transfer will be better as  
normally the sink has a more flat surface than other aluminum.

Make the outside heat sink as large as possible if you will avoid using a  
fan.

I have installed Munin and the heat sink inside Pandora but I use a  
temperature controlled fan blowing through the sink. The sink I used was  
one I had in the scrap collection, do´nt know the PN.

73, Kjell
