[hpsdr] Silly question from a learner

[Bill Tracey]

Ahhh - yes go ahead.  The Atlas is designed to be powered from a PC 
power supply.  If you want to make sure all is well,  connect the 
power supply to the Atlas with no cards installed in it and check the 
voltages on the Atlas bus connectors.  You should find:

A1,C1: +12v
A26,C26: -12v
A28,C28 -5v
A30, C30 +3.3v
A32,C32 +5v

Ozy and Janus only use the +12, -12 and +5 lines on the Atlas bus so 
you can get away without the other voltages.

Cheers,

Bill (kd5tfd)
