[hpsdr] Debugging Atlas

[Orval Chadsey]

 What I've been doing, is to get the data sheet for all the parts
that I solder or plug in.
Only the Atlas is in kit form in the HPSDR so far.
So that is the one I'm sure of.

 The Tantalum capacitors (C1-C5) have a line at the positive end,
and the board has a (+) plus sign for each one.
 The connectors have a bevel on the corner for pin A1, and the Atlas
has a square solder pad at the A1, B1 & C1 position on the board.
The bevel goes next to the J1-J6 silkscreen labels on the board.

I just use the bill of materials to look on the catalog web page,
Mouser in this case, by using the search function on their web site.
They have a link to the data sheet for each part, and I download that
for reference while building and for troubleshooting if needed.
By having the manufacturer's data sheets, along with all of the
documents provided by HPSDR, I have a "service manual" for both
assembly and maintenance.

Is this for all the boards? or just some of the boards?
