[hpsdr] OZY Startup Info

[John Koster]

Oh my,  

What causes the difference?  Is it the change from 171 to 170?  I 
substituted 170 parts for the 171 part on the Atlas because of the 
availability.  The only difference I spotted was the thickness of the 
part.  I thought marking the cathode on a diode was the accepted standard 
and didn't think to check that when I was comparing specs for the 
substitution.

I haven't received any comments back on the Atlas kits I sent out. 

Yes I have the reel of RED LEDs here.  I haven't shipped any of those yet 
with any kits.  I was just about to print the 'instruction sheet' for 
another batch, so I'll need to add some notes before I do so.
