[hpsdr] Ground: Some questions of a newbie

[Alexander Geckeler]

Dear all!

I'm a happy owner of a HPSDR Reveiver (Atlas, Ozy and Mercury) which I 
successfully brought to life two days ago with the support of Horst 
(DL6KBF) who provided me the right version of PowerSDR.

Because I feel a bit uncomfortable to have the Atlas board and the 
modules on it without any housing on my desk, I will build a case for 
it. Regarding this small project I came up with some questions re. 
ground, which I can't answer by myself because I missed the knowledge 
(To be honest, I'm a newbie).
Maybe someone of you guys can help me and give me some answers.
The questions are:
1. Is it necessary to mount ground to the Atlas board. If so, how?
2. Should Atlas be connected to the case (planned is a metall hounsing) 
and the case to ground?
3. What kind of board spacer is appropriate - metall or plastic - to 
mount Atlas into the case?

Many thanks in advance for your answers and help.

73, Alexander
