[hpsdr] Power Supply

> Pico makes four supplies that seem to be candidates, maybe.  According to
> their manuals, the -12v ratings are:
> PicoPSU-120            50ma
> PicoPSU-120-WI-32 100ma
> PicoPSU-120-WI-25 100ma
> PicoPSU-80              50ma
> 
> At the TAPR booth in Dayton I saw what looked like a Pico supply driving
> Janus and Ozy, so it appears that one of the supplies is appropriate for
> TWO boards.  My question is while the Pico supplies be adequate as Mercury
> and others are added (excluding a PA).  I notice that Mercury does not
> need -12v, but does it fit within the ratings for the other voltages?
