[hpsdr] Power Supplies

[Mike Naruta]

Ah, that's very interesting Mike.  Thank you.


I planned on outboarding the power supply.
Less heat in the HPSDR.  And my son gave
me a beautiful chromed PC supply.

I plan to have an outside connector, with
feedthru capacitors, ferrite beads, and
overvoltage and overcurrent protection,
then an internal cable to the Atlas.
I'm a shielding freak.

I hope someone can tell me part numbers of
some clamps/zeners.


Also, can someone recommend 2 and 6 pin header
sockets, as used on the UCB, Ozy, and other
HPSDR stuff?  I've poked around Mouser and
MPJA, but haven't found anything yet.
