Hi Jeroen,
Good to see this discussion on Demeter. We are very close to seeing how
well the small switching power supply that plugs directly into the ATX
connector on Atlas works with Mercury i.e. the picoPSU-120.
I am using switching regulators on all my HPSDR supplies and have no
problem with noise etc.
I suggest you review the use of a switching regulator to provide +5v
and -12v from 13.8v after the results of the above test are completed.
I am concerned that a linear regulator for the 5v supply will be very
inefficient.
